The key to any successful outdoor excursion is staying warm and comfortable<\/strong>, and your\u00a0layering system starts with base layers.<\/strong> Next-to-skin apparel is foundational for winter sports, alpine adventures, and the shoulder seasons. Base layers are made in various densities \u2014 lightweight, midweight, heavyweight \u2014 and each one provides a different degree of warmth and hand feel based on the material choice.<\/p>\n

The higher the percentage of wool, the warmer a base layer will be. Among our favorites are the medium-weight Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong> and matching Bottoms<\/strong>, which provide middle-of-the-road warmth for moderately cold days at the ski area. Wool has the bonus of holding warmth even when it\u2019s wet and beating back odors. <\/p>\n

But synthetic fabrics have a lot to offer. They\u2019re often more durable, elastic, and affordable than wool, like the Helly Hansen LIFA Crew Base Layer<\/strong>, which you can snag for less than $50. And while you tend to give up some odor control, synthetics are the fastest-drying textiles. <\/p>\n

Since this guide was first published in 2019, our team continues to thoroughly test ladies\u2019 base layers in a range of weather conditions and climates. To learn about base layers, jump down to the Buyer\u2019s Guide<\/strong>, which spotlights Price & Value<\/strong>. Also, have a look at our Comparison Chart<\/strong> to steer your decision-making.<\/p>\n

Editor\u2019s Note: We updated our Base Layers for Women buyer\u2019s guide on November 12, 2024, to include the Cotopaxi Debajo Seamless Baselayer Tight <\/strong>and Crew<\/strong>, along with additional info about odor protection in our buyer\u2019s guide. <\/em><\/p>\n

                                                  How We Tested the Best Base Layers for Women<\/h2>\n

                                                  The GearJunkie product testing team includes a range of skiers and snowboarders from intermediate to expert who explore ski areas around the world, venture into the backcountry, skin uphill at the resort, apr\u00e8s in the parking lot, and enjoy Nordic trails. We don\u2019t shy away from winter runs and embrace the mantra \u201cthere\u2019s no bad weather \u2014 only bad clothing\u201d when it comes to playing outside in the depths of winter.\u00a0<\/p>\n

                                                  Our team includes avid hunters and folks who live in wintry, cold, mountainous locations from Bozeman, Montana, to Crested Butte, Colorado. We backpack, alpine climb, hunt, and track elk in the fall shoulder season. In the spring, we go ice climbing and mountaineering. The first iteration of this guide was authored by then-contractor Morgan Tilton, in 2019, following extensive field tests. <\/p>\n

                                                  To narrow down the top 10 base layers on the market, she heavily researched, coordinated, and dispersed base layers to a diverse group of outdoor professionals and athletes nationwide, who reported detailed findings in addition to Tilton\u2019s personal field tests in Colorado. Since then, this guide has evolved through eight published updates as of September 2024. Today, the guide highlights 14 tested product collections that represent the best of the best base layers for women.<\/p>\n

                                                  GearJunkie Senior Editor Morgan Tilton specializes in snowsports and manages the majority of the publication\u2019s winter guides, including Base Layers for Women, which has been on her edit desk since 2022. Raised in Telluride, Colorado, she grew up playing at Telluride Ski Resort and now lives in Crested Butte. She\u2019s worn a ton of base layers over the past three decades \u2014 and the ladies\u2019 designs really do keep getting better.<\/p>\n

                                                  As an outdoor industry journalist, Tilton has covered winter gear for more than 12 years, including reporting for the\u00a0Snow Show Daily<\/em>, and serving as Snowboard Editor at\u00a0Teton Gravity Research<\/em>. She\u2019s Wilderness First Responder certified and has completed all three AIARE recreational-level avalanche training courses.\u00a0<\/p>\n

                                                  In addition to a sugar beet harvester and ski patrol tail guide, the contributing field testers for this guide include: <\/p>\n

                                                  Our Testing Grounds<\/strong><\/h3>\n

                                                  GearJunkie Senior Editor Morgan Tilton lives and primarily tests gear in the Elk Mountains. She skis, snowboards, snowmobiles, and shovels unbelievable amounts. She\u2019s also tested base layers on the blustery slopes of Eldora Mountain, foggy and icy days at Utah\u2019s Snowbasin Resort, powder rounds at Telluride Ski Resort, and the backcountry of the San Juan Mountains. The majority of her inbounds gear testing takes place at Crested Butte Mountain Resort, a few miles away from her shoveling habitat.\u00a0<\/p>\n

                                                  While using these second skins, we adventured across North Dakota farmlands, up cracks in Utah\u2019s Indian Creek, and throughout Colorado\u2019s high-elevation peaks and limestone walls. Temperatures stretched from splitting cold at sunrise in the glades to scorching under the sun during fieldwork.\u00a0<\/p>\n

                                                  In spring 2022 and 2023, Crested Butte Mountain Resort was the host location for the GearJunkie Ski and Snowboard week, where our team met to test goods.<\/p>\n

                                                  Our Testing Process<\/strong><\/h3>\n

                                                  Our team field tests all of the women\u2019s base layers that are included in this guide.\u00a0While the Smartwool and REI base layers constructed for extended sizes have not yet been field tested, we have onboarded plus-size testers for the winter of 2024-2025. For our current reports, we have tested those products in alternative size runs, attended plus-size apparel panel presentations, interviewed the plus-size base layer designers, and researched consumer impressions.<\/p>\n

                                                  While she teams up with many gear testers, Tilton puts goods to the grindstone between keyboard blocks. To date in 2024, Tilton has packed in 62 days and 216 hours of testing women\u2019s base layers. From January to December 2023, Tilton tested women\u2019s base layers across 68 days and 198 hours of recreation \u2014 including blizzards, sub-zero temps, harsh wind, heavy and wet snow, plenty of perspiration, and sunshine. Her outings took place in the frontcountry and backcountry including bebopping via snowmobile. But that metric excludes daily errands and shoveling responsibilities.<\/p>\n

                                                  Environmental journalist Kylie Mohr runs and skis in Montana in various and blustery conditions. She wore these base layers in and out of bounds to see what most kept her warm and dry. Avid snowboarder and Utahan Julia Spadaro spends her winters at the resort and splitboarding in the backcountry, as well as hiking in the shoulder seasons. She tests women\u2019s base layers throughout her adventures and delivers knowledgeable reports on what she does and doesn\u2019t like.<\/p>\n

                                                  Testing Metrics<\/strong><\/h4>\n

                                                  Throughout our field tests and personal experience, we determine the most competitive women\u2019s base layers based on a variety of metrics including quality, comfort, fit, longevity, and value. We take a close look at each product\u2019s warmth, breathability, wicking and drying capability, material, elasticity, stretch, weight, density, seams, hems, cut, hand feel, and style.<\/p>\n

                                                  We also consider the most innovative, sustainable, legacy, award-winning, and popular designs on the shelf today. Hands down, these women\u2019s base layers serve a wide range of athletes, applications, and budgets.<\/p>\n

                                                  Buyer\u2019s Guide: How to Choose the Best Women\u2019s Base Layers <\/h2>\n

                                                  In our guide, we focus on the best options for cold weather and the winter season, which are often long-sleeve tops and ankle-length bottoms.<\/p>\n

                                                  Technically, women\u2019s base layers feature a range of designs, including tank, long-sleeve, and short-sleeve tops, as well as ankle-length or capri pants. Some tops feature a hood, partial zipper, or thumb holes. Others are tailored with a crew collar, mock neck, or turtleneck. While most against-skin layers lack pockets, we\u2019ve seen leggings popping up with a spacious side pocket, which is useful to stash a phone, especially post-activity when you pull off your snow pants.<\/p>\n

                                                  Two fundamental umbrellas will help you decide which women\u2019s base layers to buy: <\/p>\n

                                                    \n
                                                  • You\u2019ll want to consider how cold the climate is where you play outside. The colder the zone, the more you\u2019ll want to consider a wool-based blend, higher-density fabric, and heavier fabric weight.<\/li>\n
                                                  • The second variable is how active you\u2019ll be while you\u2019re wearing that apparel. During exercise, like shoveling or going on a winter run, your body is generating heat that would necessitate a more breathable, less density, low-weight top and bottom. <\/li>\n<\/ul>\n

                                                    If you plan on being physically active in above-freezing but cool weather, we recommend a synthetic blend. If you\u2019ll be rounding out winter days in a below-freezing climate, wool can be your greatest companion for warmth. Other factors can influence the best base layer choice including your body\u2019s circulation, skin sensitivity to fibers (like wool), and the layers you put on top. <\/p>\n

                                                    Layering System\u00a0<\/strong><\/h3>\n

                                                    Your alarm goes off. Don\u2019t snooze: It\u2019s time to get up and dressed for cold weather fun. Your layers will work in a tiered system:<\/p>\n

                                                      \n
                                                    • Base Layer:<\/strong> Next to skin to wick sweat<\/li>\n
                                                    • Midlayer<\/strong>: Adds warmth to retain body temperature<\/li>\n
                                                    • Outer Layer:<\/strong> Protection from the elements, repels precipitation, blocks wind; insulated outer layers increase warmth <\/li>\n<\/ul>\n

                                                      First, put on your underwear and socks. They better be wool or a synthetic blend \u2014 not cotton. Your warm, dry epidermis will thank you.\u00a0Your base layers go on next. <\/p>\n

                                                      Base Layer<\/strong><\/h4>\n

                                                      Add your base layer top, bottom, or onesie. If your bottoms are long, make sure they go over your socks. Unless you like your socks on the outside of your bottoms \u2014 that\u2019s personal preference. If your bottoms are mid-shin length, like some compressive performance options, adjust your socks and fabric, so there aren\u2019t any overlapping, uneven points that could rub or chafe.\u00a0<\/p>\n

                                                      Midlayer<\/strong><\/h4>\n

                                                      Now, it\u2019s time to slip on your midlayer top and bottom, depending on the day\u2019s activity.\u00a0<\/p>\n

                                                      Going skiing in bounds? Reach for a streamlined fleece that still allows a full range of motion. Hanging out at the campsite? Pull on a bulky deep-pile sherpa fleece.<\/p>\n

                                                      Your activity will dictate what appropriate midlayers to add on the bottom. Maybe you\u2019ll pull on a fleece or insulated puffy pants for extra warmth below workwear trousers or snow bibs.\u00a0\u00a0<\/p>\n

                                                      Outer Layer<\/strong><\/h4>\n

                                                      Headed to the backcountry? Wear a comfy insulated jacket on the way to the trailhead then strip down to your baselayer or midlayer to start, given you\u2019ll quickly warm up from exertion in the cold temps. Running in a breeze on an otherwise warm afternoon? Go for a softshell with no insulation.<\/p>\n

                                                      If we\u2019re resort skiing in below freezing temps, and we run cold, we\u2019ll often do this trio: an uninsulated ski shell over both a fleece and puffy jacket. Insulated jacket wearers will likely find they don\u2019t need all three.\u00a0<\/p>\n

                                                      An ideal layering system is all about learning what works for you and how many layers you need to stay warm and dry.<\/p>\n

                                                      Fabric Blends<\/h3>\n

                                                      The fabric blends of women\u2019s base layers include wool, synthetic, or a blend of the two. Within those fabrics, there are various densities from lightweight to midweight or heavyweight.<\/p>\n

                                                      Wool<\/h4>\n

                                                      We love wool. It regulates temperature really well and provides warmth when it\u2019s damp or wet. It\u2019s evolved to be much more comfortable against the skin and resists odors like a champ. The warmth-to-weight ratio is high, packing a punch in a fairly light package. It\u2019s an ideal choice for low-intensity outdoor activities like ice fishing or spectating a hockey game. Among our top base layer choices are the\u00a0Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong>\u00a0and\u00a0Smartwool Women\u2019s Classic Thermal Merino Base Layer Bottom<\/strong>, a 100% Merino wool collection.<\/p>\n

                                                      That said, 100% merino wool tends to be less stout than synthetics, wears holes more quickly, and can get baggy throughout use. If you have sensitive skin, even the smoothest 100% merino wool might feel a tad less than cloud-like next to the skin. Wool gets heavier when it\u2019s wet and doesn\u2019t dry as fast as synthetics. Depending on your preference, activity level, and the weather conditions, you might prefer a wool blend or straight synthetic materials.<\/p>\n

                                                      Wool can cost more than its counterparts. Beyond merino-sourced wool, we have tested base layers with wool from yaks, which was a premium thread, extremely soft, and super insulating.<\/p>\n

                                                      Synthetic<\/h4>\n

                                                      An alternative to wool is a synthetic fabric, which is typically a blend that includes polyester plus elastane or spandex for rebound, form, and long-lasting use. Some synthetic fabrics are proprietary to a brand with treatments that enhance their odor-fighting ability and moisture-wicking prowess \u2014 the qualities that occur naturally in wool.<\/p>\n

                                                      Synthetic blends do not offer as much warmth and overall temperature regulation that wool provides. Because they don\u2019t absorb as much moisture and they dry fast, they\u2019re a great choice for high-intensity activities that produce a lot of perspiration without long moments of standstill, like during a hunt, when a chill could set in.<\/p>\n

                                                      These fibers can work really well for people with sensitive skin, especially for exercise use, and the bonus of greater durability, stretch, and elasticity. Also, synthetics typically cost less than wool. One of our favorite synthetic options is the\u00a0REI Co-op Lightweight Base Layer Tights Women\u2019s Plus Sizes<\/strong>, at a whopping $40.<\/p>\n

                                                      One drawback: Odor-intense days are not typically covered up well by this fiber in its naked form. <\/p>\n

                                                      Wool-Synthetic Blend<\/h4>\n

                                                      Many folks find a fair balance of managing heat and chill, sweat absorption, and covering up odors in a design that weaves together both wool and synthetic fibers. Adding synthetics to blends can enhance the strength and overall lifespan of wool apparel. <\/p>\n

                                                      One of our all-time favorites for wearing from the skin track to happy hour is the Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong><\/strong>, which includes 5% elastane and maintains a nice shape throughout long days.<\/p>\n

                                                      Weight<\/strong> Class or Thermal Category: Lightweight, Midweight, Heavyweight<\/h3>\n

                                                      When you shop for women\u2019s base layers, the products are categorized by three weight zones, which generally refer to how heavy or light the layer is and feels. The weight class is influenced by the fabric density and thickness, which changes the activities that the layer is compatible with.<\/p>\n

                                                      Here, we listed the weight class in each product\u2019s specs \u2014 under Thermal Category \u2014 which is based on our test results.<\/p>\n

                                                      Weight class isn\u2019t directly correlated to warmth. A lightweight, pure wool top can bounce back a ton of body heat. It will be easier to move in, less dense, and more breathable than a midweight or heavyweight wool design.<\/p>\n

                                                      While everyone\u2019s circulation and preferences are different, here\u2019s a general starting point for deciphering a weight class based on activity level and outdoor temperature:<\/p>\n

                                                      Sedentary:<\/strong><\/p>\n

                                                      • 15-25 degrees: Midweight, wool<\/li>\n

                                                        Active: <\/strong><\/p>\n

                                                        • 25-32+ degrees: Lightweight, synthetic<\/li>\n
                                                        • 15-25 degrees: Lightweight, wool-synthetic<\/li>\n
                                                        • \n<\/li>\n<\/ul>\n

                                                          Well-made base layers dry fast, so you can lounge in your kit after activity; (photo\/Xander Bianchi)<\/figcaption><\/figure>\n

                                                          Lightweight<\/h4>\n

                                                          If you\u2019re running hardpack snow trails, snowshoeing, skate skiing, or doing uphill ski workouts in 30-degree temps, a lightweight base layer top or bottom should do the trick, as long as there\u2019s no wind chill.<\/p>\n

                                                          Lightweight layers dump heat really well. These could be a good piece for warmer spring laps at the ski resort. But sitting idle on lift rides in cold temps typically calls for a warmer midweight base layer. One of our favorite lightweight synthetics is the Helly Hansen Women\u2019s HH LIFA Long-Sleeve Crew Base Layer<\/strong> and a lightweight wool blend that\u2019s super soft and versatile is the Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong>.<\/p>\n

                                                          Midweight<\/h4>\n

                                                          Not too airy and not too stuffy, the midweight base layer is optimal for wintry days skiing and riding at the resort. It\u2019s a good choice for snowmobiling, when pulling the throttle can pack windchill at high speeds.<\/p>\n

                                                          That said, for intense heat-building activities like huge ski or splitboard tours or snowshoeing, a midweight layer might be too much unless the temps are colder, like 15 degrees or less. <\/p>\n

                                                          Squarely midweight, we love the\u00a0Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong>\u00a0and\u00a0Smartwool Women\u2019s Classic Thermal Merino Base Layer Bottom<\/strong>\u00a0<\/strong>as a well-rounded kit for cold or below-freezing temps and days at the ski resort. <\/p>\n

                                                          Heavyweight<\/h4>\n

                                                          When we\u2019re talking extreme temperatures \u2014 15 degrees with windchill to well below freezing \u2014 then your best bet is a heavy-set base layer, especially for ski resort laps when you are sedentary on the way up. <\/p>\n

                                                          Other more passive outdoor activities could include ice fishing, sailing, hunting, spectating events, hanging at base camp during a mountaineering expedition, or snowmobiling groomed trails, especially if sightseeing stops are frequent.<\/p>\n

                                                          We don\u2019t currently have any bulky heavyweight options in our guide. Many of our 100% wool midweight selects can be layered beneath a midlayer fleece and down jacket for super cold conditions, and we prefer that versatility. The Kari Traa Rose Half Zip Baselayer Top<\/strong>\u00a0and\u00a0Kari Traa Rose High Waisted Baselayer Pants<\/strong>\u00a0feel lean but are packed with heat. These are our go-to on a 0-degree day at the ski resort. We don\u2019t usually like wearing these while we ski tour to avoid an oven effect.<\/p>\n

                                                          Fabric <\/strong>Density<\/h3>\n

                                                          A standard unit for measuring fabric density is gsm (grams per square meter). The higher the gsm, the denser and warmer that textile will be. A fluid-feeling blouse might be as low as 50-100 gsm, while denim reaches into the 340-450 gsm range.<\/p>\n

                                                          Some women\u2019s base layers do not weigh much but have a dense fabric or high gsm. Therefore, they swing a high warmth-to-weight ratio, such as\u00a0the Kari Traa Rose High Waisted Baselayer Pants<\/strong> with 240 gsm. After testing, we associated that legging as midweight, thanks to the relatively low density yet high heat punch. <\/p>\n

                                                          Rather than adding gsm labels to our product reviews here, we shared the general weight class \u2014 lightweight, midweight, and heavyweight \u2014 which is more ubiquitously used across brands. Our listed weight class is based on our test results. That said, understanding how to interpret the density of a base layer is a very useful tool. <\/p>\n

                                                          Here\u2019s a broad rule of thumb for gsm: <\/p>\n

                                                            \n
                                                          • Ultralight base layers:<\/strong> >150 gsm<\/li>\n
                                                          • Lightweight base layers:<\/strong> 150-195 gsm<\/li>\n
                                                          • Midweight base layers:<\/strong> 195-250 gsm <\/li>\n
                                                          • Heavyweight base layers:<\/strong> 250-320 gsm<\/li>\n<\/ul>\n

                                                            You\u2019ll want to match your physical exertion or circulation to the fabric density. If you plan to do high cardio activity, choose a base layer design with a lower density.<\/p>\n

                                                            If you plan to be more sedentary \u2014 such as waiting in long ski lift lines during a blizzard, ice fishing, watching a hockey game, or running errands \u2014 opt for a higher gsm. A higher fabric density is also a good option for folks who have poor circulation or tend to get chilled during winter activities.<\/p>\n

                                                            In addition to trapping heat, it\u2019s important for your base layer to breathe well and efficiently wick moisture. Freezing sweat will make you colder faster. Generally, the lighter or less dense a design is, the more breathable it will be. Merino wool is also more breathable than synthetics. Base layers can be made with a blend of materials that place more breathable textiles in high-heat zones.<\/p>\n

                                                            When we\u2019re talking about engineering, we can\u2019t forget about the Icebreaker 260 ZoneKnit Long Sleeve Crewe Thermal Top\u00a0and Icebreaker 260 ZoneKnit Thermal Leggings, <\/strong>which have a breathable mesh-like merino wool layer in all the important places \u2014 the lower legs, behind the knees, across the back and upper glutes, under the arms \u2014 so sweat can\u2019t ruin the day. The Kari Traa Rose Half Zip Baselayer Top<\/strong>\u00a0uses a lighter density merino wool under the arms and along the sides, which feels more breathable.<\/p>\n

                                                            In general, we found that the Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong> <\/strong>is a warm winter layer that breathes pretty well. It\u2019s our top pick for the dead of winter but also for alpine pursuits in fall and winter. The Voormi Women\u2019s Baselayer Bottoms Full Length<\/strong> and <\/strong>Long Sleeve Baselayer Crew<\/strong> also breathe rather well and repel water, keeping us dry after sweaty ascents and snowmobile rips.<\/p>\n

                                                            If you know you\u2019re going to be busting it uphill on a warm day in the springtime, look for an even lighter and more breathable layer. Something like the Helly Hansen Women\u2019s HH LIFA Long-sleeve Crew Base Layer or REI Co-op Lightweight Base Layer Tights Women\u2019s Plus Sizes<\/strong> and T<\/strong>op<\/strong> will be a key part of your layering system.<\/p>\n

                                                            If you\u2019re packing minimally for multiday use, like a hut-to-hut ski, merino wool does wonders with hiding odors. Generally, synthetic materials don\u2019t resist odor as well as this natural fiber. Merino wool wicks sweat away from your body, allowing it to evaporate rather than sink into your clothes. Wool fibers absorb nearly twice as much water vapor as cotton and 30 times as much as polyester. The structure of wool binds with odors, playing keep away from bacteria.\u00a0<\/p>\n

Silver-based compounds and triclosan and triclocarban treatments are toxic to odor-causing bacteria, keeping the nose-pinch at bay. Keep in mind that these treatments\u2019 effectiveness could decrease over time as a garment is washed.\u00a0<\/p>\n

                                                            Many base layers hidden beneath midlayers or outerwear jackets will never see the light of day. But others, especially lightweight ones geared for year-round or springtime use, will. That\u2019s where sun protection is a nice added feature. <\/p>\n

                                                            The REI Co-op Lightweight Base Layer Long-Sleeve Crew Top Women\u2019s Plus Sizes<\/strong> boasts a UPF rating of 50+, as does the Le Bent Women\u2019s Feathertop Ultralight Hooded Long Sleeve Tee<\/strong>. But Le Bent\u2019s design also offers a hood, so you\u2019re getting additional protection of your ears, plus the back of the neck. The Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong><\/strong> likewise sports a UV 50+ tag. <\/p>\n

                                                            Durability<\/h3>\n

                                                            Thermal layers are an investment, so it makes sense that you want them to last. They\u2019re also only one piece of a long list of gear that\u2019s needed to venture out in the winter. <\/p>\n

                                                            Synthetic layers are often more steadfast than wool but can cause more trouble with retaining odors. Manufacturers often add synthetic fibers to their wool apparel to help increase the overall timestamp. Wool is naturally warmer and odor-fighting but tends to be more fragile. You\u2019ll want to take care putting them on, as well as how you wash and dry them. <\/p>\n

                                                            Hands down, the most durable construction of any of these base layers is that of the Voormi Women\u2019s Baselayer Bottoms Full Length<\/strong> and\u00a0Voormi Women\u2019s Long Sleeve Baselayer Crew<\/strong>. In the brand\u2019s proprietary process, in-house seamsters create their Dual Surface material, a precision-blended wool technology with a lean interior layer of fine micron-wool plus a portion of polyester and nylon. After several years of use, we don\u2019t see holes surfacing in these layers any time soon. <\/p>\n

                                                            Women\u2019s base layers come in a range of creative patterns and colors; (photo\/Jason Hummel)<\/figcaption><\/figure>\n

                                                            Comfort & Fit<\/h3>\n

                                                            Most base layers offer a degree of flexibility and are soft or nonabrasive, which supports overall comfort and fit. But some base layers we\u2019ve tested in the past have had a tighter compression fit for optimal athletic performance. <\/p>\n

                                                            One of the more challenging base layers to pull on is the Voormi Women\u2019s Baselayer Bottoms Full Length<\/strong> and\u00a0Voormi Women\u2019s Long Sleeve Baselayer Crew<\/strong>, especially at the seams. However, we love how tough and durable this design is. The next most close-fitting design in our guide is the Halfdays Hallie Midweight Merino Legging<\/strong>, but it does offer ample stretch, even along the seams.<\/p>\n

                                                            When we test base layers, we\u2019re looking for tops that provide enough range of motion across the chest and shoulders, as well as when lunging or squatting. The seams need to be smooth or flat, and the gusset needs to be well-constructed so we don\u2019t feel any jabs or experience chafing. The construction is very smooth across the Ortovox 185 Rock\u2019N\u2019Wool Short Pants<\/strong>\u00a0and Ortovox 185 Rock\u2019N\u2019Wool Long Sleeve<\/strong>.<\/p>\n

                                                            We care about the silhouette, because we prefer arms that at least cover our wrists and torso lengths that don\u2019t allow the lower back to be exposed to the elements. <\/p>\n

                                                            Pant Length\u00a0<\/strong><\/h4>\n

                                                            Most base layer pants reach down to your ankle but some capri styles hit below the knee, near the shin bone. We like a cropped length for easy layering with our socks and ski boots. The Ortovox 185 Rock\u2019N\u2019Wool Short Pants<\/strong> reach the knee and eliminate the need to layer our pants over socks.<\/p>\n

                                                            Bottoms that reach closer to your feet are usually tapered and snug, so they can be easily tucked in when necessary. But there\u2019s usually enough pliability in the fabric to slide your winter socks underneath if you prefer.\u00a0<\/p>\n

                                                            A higher fabric density and weight often correlates with a warmer base layer; (photo\/Jason Hummel)<\/figcaption><\/figure>\n

                                                            Onesie & Drop Seat<\/strong><\/h3>\n

                                                            Sometimes a separate top and bottom just won\u2019t cut it. We\u2019re thinking about those best-of-the-season powder days where a gap in base layer coverage could lead to snow where the sun doesn\u2019t shine. Base layers with a seamless connection are a rare, but increasingly popular, option in the base layer lineup. They\u2019re called onesies or one-pieces that include a top and a bottom sewed together. Think wet suits and footie pajamas.\u00a0<\/p>\n

                                                            Leading the charge is the Wild Rye<\/strong> Olivia Onesie<\/strong> base layer. Wearers are treated with head-to-toe merino wool. A hood adds coziness, and fun patterns like chunky yellow florals stand out against your friends\u2019 all-black arsenal. A half-zip helps regulate temperature on this warm, 230 gsm style. <\/p>\n

                                                            The best feature on a onesie is a rear zip \u2014 or drop seat \u2014 for easy release. The drop seat is a removable backside flap, usually with zippers that span hip to hip above your booty, to make using the bathroom easier. No one likes having to get totally naked to answer nature\u2019s call. Brr! Though we haven\u2019t tested this one yet, the Backcountry Airblaster Merino Ninja Suit<\/strong> <\/strong>is another onesie option on the market. \u00a0<\/strong><\/p>\n

                                                            Base layer pants can help protect the legs when vents are open, especially if the design lacks a mesh liner; (photo\/Eric Phillips)<\/figcaption><\/figure>\n

                                                            Hoods & Collars\u00a0<\/strong><\/h3>\n

                                                            Hoods are fairly rare on base layer tops. After all, how many hoods do you really want to be wearing at once? Hoods can sometimes add bulk around the neck and head area, especially if your base layer, fleece, puffy, and shell all have one. <\/p>\n

                                                            But some of our favorite base layers rock a hood, like the First Lite Kiln Hoody<\/strong> and the Le Bent Women\u2019s Feathertop Ultralight Hooded Long Sleeve Tee<\/strong>, which is superb for spring mountaineering and sunny, warm ski tours. It can be nice to have a slender hood around your neck to layer under a helmet or hat, which can further block the sun and wind.\u00a0<\/p>\n

                                                            Certain base layers have a scoop neck, while others have collars with a quarter- or half-zipper at the chest and d\u00e9colletage. We like a mock turtleneck cut to fully protect our neck and chest without the restriction of a full turtleneck. The Kari Traa Rose Half Zip Baselayer Top<\/strong> combines a half-zip with a mock turtleneck.<\/p>\n

                                                            Thumbholes can provide additional coverage over the wrists and hands but so can long arms like this\u00a0Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong><\/strong>; (photo\/Eric Phillips)<\/figcaption><\/figure>\n

                                                            Sleeve Cuffs & Thumbholes<\/strong><\/h3>\n

                                                            On long-sleeve base layers, the cuff is a piece of fabric that demarcates the garment\u2019s edge at the wrist. It\u2019s sewn on to help prevent fraying and increase comfort. The lengths of base layer sleeves, as well as the depth and elasticity of their cuffs, can greatly vary. Longer sleeves can reach the knuckles, covering the backs of the hands and palms. Others end at the wrist before extending over the hand.<\/p>\n

                                                            Thumb holes, also known as thumb loops, are technical slits in long cuffs in which the thumbs can sit in. It\u2019s like a seatbelt on a cocoon that helps to keep your hands and wrists warm. Adding thumb loops helps the sleeve stay drawn across the hand. That way, the fabric won\u2019t bunch up when you pull on your outer jacket.<\/p>\n

                                                            The precise width and placement of the loop that goes around your thumb varies by brand and design. A handful of thumbhole designs are simple elastic bands. But many thumbhole designs are created with a wide piece of fabric and include seams.<\/p>\n

                                                            Sometimes, thumbholes can be tedious to slide into, cumbersome under ski gloves, or incompatible with a watch. Some ski jacket designs have built-in wrist gaiters with thumbholes, which leads a traffic jam around your wrist \u2014 and at worst, poorer circulation \u2014 if your base layer top also has thumbholes. <\/p>\n

                                                            We especially like the thumbholes on the Black Diamond Women\u2019s Solution 150 Merino Baselayer Crew<\/strong><\/strong>. They are stretchy enough to be comfortable while wearing them for back-to-back hours. The Wild Rye Olivia Onesie<\/strong>\u00a0<\/strong>thumbholes include a beefy cuff, so they\u2019re cozy to wear indoors, but outside, we pull them back to put on gloves. We found the thumbholes of the Voormi Women\u2019s Long Sleeve Baselayer Crew<\/strong>\u00a0to be too small and restrictive, greatly due to the lack of stretch in the seams. The First Lite Kiln Hoody<\/strong>\u00a0thumbholes are really easy to pull on and off, as are the ones on the Icebreaker 260 ZoneKnit Long Sleeve Crewe Thermal Top.<\/p>\n

But conscious consumers can shop with Mother Nature and humanity in mind. <\/p>\n

                                                            Finding sustainable base layers includes recycled materials, ethically sourced materials, and responsible manufacturing facilities like those that don\u2019t dump harmful toxins into nearby waterways and pay their employees a livable wage.\u00a0<\/p>\n

                                                            Certified Materials<\/strong><\/h4>\n

                                                            Some women\u2019s base layers are certified by Blu<\/strong>esign<\/strong>, an organization that works to keep chemicals out of the supply chain for the health of humans, wildlife, natural resources, and the earth. Approved factories meet standards for pollution control and worker safety. Products reach those standards partially or as a whole.\u00a0The Helly Hansen Women\u2019s HH LIFA Long-sleeve Crew Base Layer<\/strong> is Bluesign-approved. <\/p>\n

                                                            The Le Bent Women\u2019s Feathertop Ultralight Hooded Long Sleeve Tee<\/strong>\u00a0features Nuyarn fibers, which set an impressive benchmark: Responsible Wool Standard Certified, Bluesign-certified, Oeko-Tex Standard 100, and the Global Organic Textile Standard.<\/p>\n

                                                            Similarly, the REI Co-op Lightweight Base Layer Tights Women\u2019s Plus Sizes\u00a0<\/strong>and <\/strong>Top<\/strong> <\/strong>is made in a Fair Trade certified factory. That certification means the factory meets safe working conditions as well as environmental protections and that the supply chain is transparent. Ortovox gives two stamps to its Ortovox 185 Rock\u2019N\u2019Wool Short Pants<\/strong>\u00a0and\u00a0Ortovox 185 Rock\u2019N\u2019Wool Long Sleeve<\/strong>: validation from the Fair Wear Foundation for equitable working conditions and climate neutrality.<\/p>\n

                                                            We\u2019ve seen the brand\u00a0Daehlie <\/strong>do well with material sourcing for products, selecting fiber from fast-growing eucalyptus trees on a farm that\u2019s certified by the Forest Stewardship Council. <\/p>\n

                                                            Using textiles sourced from recycled materials, such as old plastics, is one way that companies reduce waste and demand for petroleum-based products. Materials can be partially or fully recycled, like the recycled polyester in the Patagonia Capilene line.\u00a0<\/p>\n

                                                            Smartwool<\/strong> argues that wool is an inherently responsible choice: It\u2019s not plastic, and it breaks down in water and soil. The brand\u2019s wool is ZQ-certified by a New Zealand-based group that sets standards for animal welfare, social responsibility, and environmental sustainability. You\u2019ll see this wool in the Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong> and Bottom<\/strong>, as well as all of the brand\u2019s base layer offerings.\u00a0<\/p>\n

                                                            Our favorite women\u2019s base layers run from $40 to $229. That includes options for the budget-conscious shopper and the athlete wanting to splurge on a technical textile.<\/p>\n

                                                            The most economic choices have a basic construction, fit, and work well. The blends are synthetic, not as complex or articulated, and typically do not include wool. You won\u2019t find pockets in the leggings. The weight category, thermal power, and fabric density is usually lower. You probably won\u2019t see a synthetic fabric coated to block odors. <\/p>\n

                                                            But if you need a basic base layer for sledding and ski hill laps, these certainly get the job done. On this lower end, there\u2019s the REI Co-op Lightweight Base Layer Tights Women\u2019s Plus Sizes<\/strong><\/strong> and Long-Sleeve Crew Top<\/strong>, each for $40, and the Helly Hansen Women\u2019s HH LIFA Long-Sleeve Crew Base Layer<\/strong> <\/strong>at $45. <\/p>\n

                                                            In the \u201c100 bucks, give or take\u201d shelf, you\u2019ll see a bump up in the complexity of the textiles, how they\u2019re constructed, as well as a slightly higher quality and softer feel of materials. Merino wool enters the game. <\/p>\n

                                                            These are among our favorite base layers out there. We\u2019ve got the Smartwool Women\u2019s Classic Thermal Merino Base Layer Crew<\/strong> and Bottom<\/strong> for $115. There\u2019s also the Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong> <\/strong>for $105. The Ortovox 185 Rock\u2019N\u2019Wool Long Sleeve<\/strong> and matching Short Pants<\/strong>\u00a0are tagged at $110-$100.\u00a0Despite being super cohesive and inherently water resistant, the Voormi Women\u2019s Baselayer Bottoms Full Length<\/strong> and <\/strong>Long Sleeve Baselayer Crew<\/strong>\u00a0sits at $119.<\/p>\n

                                                            While the Wild Rye Olivia Onesie <\/strong>is available at $249, it\u2019s close to a mid-tier price point when you consider the price of a bottom and a top base layer that\u2019s woven together in a single package. This stylish one-piece is the most technical to create and includes a drop seat for bathroom breaks.<\/p>\n

                                                            But those tad higher price points include the Kari Traa Rose Half Zip Baselayer Top<\/strong> for $120 (the Kari Traa Rose High Waisted Baselayer Pants<\/strong> are labeled at $110), which is woven with high-quality wool from merino sheep, has an articulated cut and the patterns are stylish.

                                                            Base layers \u2014 as their name implies \u2014 are meant to be worn as the base of your clothing system, next to your skin. If you pile on cotton underwear and a cotton T-shirt under your base layers, you\u2019re negating all the ways a base layer is intended to work. Most base layer bottoms are intended to be worn as long underwear. Incredibly soft base layers like the Le Bent Women\u2019s Core Lightweight Crew Base Layer<\/strong><\/strong><\/strong> make this a breeze.<\/p>\n

                                                            Be sure to pick out a chest layer from The Best Sports Bras of 2024 that can stay put, wick sweat, and help keep you comfortable in winter\u2019s playground.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n

                                                            A base layer should have a close fit to your body without sacrificing freedom of movement. Some of our favorite base layers are tight-ish, but not restrictive or circulation-ending, while others are a tad roomier but not bulky.<\/p>\n

                                                            Also, your skin and the fabric need to be touching in order for the base layer to do its job: absorb moisture. Base layers that are too loose, or saggy under the arms or around the groin or torso, can\u2019t efficiently wick sweat.\u00a0<\/p>\n

                                                            Unless they\u2019re heavyweight and bulky, most base layers should fit nicely beneath a fleece midlayer, as well as a pair of Carhartt pants, overalls, or ski outerwear.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n

                                                            Really, it comes down to what you can afford and what activities you do. Most of the women\u2019s base layers on this list are 100% wool, a wool-synthetic blend, or a synthetic blend. Synthetics are highly relentless, high-wicking, and can be treated with odor-beating technology. Synthetics usually have a lower price tag.<\/p>\n

                                                            Wool is less staunch, but it has temperature-regulating properties that can work in a wide range of weather. Wool combats odors and also wicks well. Wool, often sourced from Merino sheep, typically costs more than synthetic blends. In blends, wool is woven with other fibers for longevity, elasticity, and fit. The percentage of wool varies in each design, which is why some blends are warmer than others. Be sure to check the percentage of wool to get a better idea. The Black Diamond Women\u2019s Solution 150 Merino Baselayer Crew<\/strong> is approximately three-quarters wool and one-quarter polyester.<\/p>\n

                                                            The weight category of the apparel you choose is also important. Some people will do well with a pair of lightweight base layers. If you\u2019re perpetually cold or doing a sedentary winter activity, grab midweight or heavyweight base layers or a wool blend. If you\u2019re buying base layers to backcountry ski, run, or another intense activity, go light. <\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n

                                                            For the greatest warmth and protection, you\u2019ll want to wear full underwear and a sports bra followed by base layers, which wick sweat and help manage body heat during high output or laidback activities.<\/p>\n

                                                            Base layers fit beneath a mid-layer \u2014 like a fleece, micro-down jacket, or synthetic insulation layer \u2014 followed by an outer layer, like a shell, that protects against the elements from precipitation to wind. The shell can be insulated or non-insulated. <\/p>\n

                                                            Depending on the day\u2019s activity and climate, you might prefer to wear a base layer beneath an outer layer and skip that middle piece of insulation.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n

                                                            Of course, for us gals, bras are often a necessity, especially during activity. So don\u2019t make the mistake of wearing a non-wicking bra beneath your base layers. Find yourself a\u00a0sports bra<\/strong>\u00a0that fits, wicks, and supports to combat sweat and chills on your upper half. Then let any of these base layers work their magic!<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n

                                                            A women\u2019s base layer top and bottom are essential components of your ski and snowboard gear. They build the base \u2014 literally \u2014 for a warm, dry day on the slopes. <\/p>\n

                                                            Improper layering, or having materials like cotton next to your skin, is a recipe for a wet, cold, disaster. Getting sweaty without a good base layer to wick away moisture or one that quickly dries can lead to serious body chills, discomfort, loss of energy, and can steal away the fun. Getting goosebumps outside on a winter day is a mild inconvenience at best and potentially deadly at worst, leading to hypothermia if you\u2019re not near a place where you can warm up, like in the backcountry.<\/p>\n

                                                            Basically, base layers will help you stay warmer on the slopes, so you can happily ski bell to bell or midday to apr\u00e8s.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
