What to know:<\/strong> The best base layers manage moisture and regulate body temperature in cold weather. After testing all last winter, our team of expert testers named the Smartwool Thermal Merino Mock Neck<\/a> the best overall base layer for women, and the <\/em>Kari Traa Saga Half Zip<\/a> and Pants<\/a> the warmest base layer for women. Keep reading for four more top recommendations.<\/em><\/p>\n

You can\u2019t construct a strong building on a weak foundation. The same goes for layering. The best waterproof shell in the world won\u2019t save you if you don\u2019t wear a solid base layer underneath. But instead of concrete and lumber, base layers are built from fabric\u2014technical when you\u2019re skiing, and cozy for apr\u00e8s or yurt life. The market is flooded with options these days, from high-quality natural fibers\u00a0and proprietary blends to fun patterns and various fits.<\/p>\n

Our crew of badass mountain women put almost 70 base layer tops and bottoms through the wringer last winter on hut trips in British Columbia, resort skiing in the Swiss Alps, and backyard missions in the Tetons, Sierra Nevada, and Cascade Mountains. We braved blisteringly cold temps, relentless storms, slushy spring conditions, and even a little bit of rain, evaluating the best women\u2019s base layers for warmth, comfort, breathability, style, and fit.<\/p>\n

Best Overall Base Layer for Women<\/strong><\/h2>\n

Smartwool Thermal Merino Mock Neck<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Merino wool<\/p>\n

Pros and Cons<\/strong>
+ Stylish for apr\u00e8s and town wear
+ Midweight design is highly versatile
\u2013 Mock neck can interfere with hoods<\/p>\n<\/section>\n

We hardly went any days last winter without the Smartwool Classic Thermal Merino Mock Neck base layer. Comfortable and cute, this long-sleeve joined us for bell-to-bell days at Jackson Hole and hut trips in Switzerland. \u201cI loved that I could wear it all day and into the evening too,\u201d said one tester after skiing in Italy. \u201cIt\u2019s like a cute winter top that\u2019s technical. Plus, it never stinks.\u201d<\/p>\n

The full merino wool construction provided optimal warmth and breathability on the hill. Testers wore this layer under shells and insulation and even on its own in temps ranging from \u221210 to 52 degrees F, dubbing it \u201cthe most versatile layer in the closet.\u201d<\/p>\n

The fit isn\u2019t as snug as other base layers for women\u2014so it\u2019s flattering and relaxed enough to pair with jeans but fitted enough to keep chilly air from sneaking in. The only complaint? A couple testers felt the mock neck was bulky when paired with a neck gaiter and a stack of hoods.<\/p>\n

Best Value<\/strong><\/h2>\n

Quince Merino Wool All-Season Base Layer Long Sleeve and Cold-Weather Legging<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Merino wool<\/p>\n

Pros and Cons<\/strong>
+ High value
+ Comfortable fit
\u2013 Top isn\u2019t super warm<\/p>\n<\/section>\n

Merino wool for under $50? You have our attention. Quince usually isn\u2019t our first stop for outdoor gear, but when we saw affordable merino base layers for women among their offerings, we knew we needed to take a set into the mountains. After wearing them on storm days and springlike conditions at Jackson Hole Mountain Resort in February, testers were impressed with Quince\u2019s basic and lightweight merino wool long-sleeve and leggings.<\/p>\n

\u201cIf you hadn\u2019t told me this top cost less than $50, I would never have been able to tell,\u201d said one Idaho tester after a ski tour on Teton Pass. \u201cIt\u2019s comfy, breathable, and just kind of disappears.\u201d<\/p>\n

Both the tights and crew top are fitted but not overly tight for a sleek, next-to-skin fit that we put on and never fussed with. We found that the women\u2019s base layer top wasn\u2019t the warmest: On an 18-degree F day at Grand Targhee Resort, we found ourselves reaching for an extra midlayer. But on the plus side, we\u2019ll keep these in the rotation for spring camping trips, too. The tights are closer to midweight, and we found them perfectly toasty for days ranging from 15 to 40 degrees F.<\/p>\n

Warmest Base Layer<\/strong><\/h2>\n

Kari Traa Saga Half Zip and Pants<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Wool<\/p>\n

Pros and Cons<\/strong>
+ Extremely warm
+ Stylish
\u2013 Not very breathable
\u2013 Stretches out after wear<\/p>\n<\/section>\n

Cozy warmth meets Scandinavian style with the Kari Traa Saga Half Zip and Pants. Testers found this knit wool set to be the warmest in the women\u2019s base layers test, providing sweet relief from the most frigid days on the hill. \u201cThis kit was perfect for early Tram at JHMR on a 10-degree F morning,\u201d said one tester. \u201cWhile everyone else was shivering, I was on the porch eating a waffle.\u201d<\/p>\n

The form-fitting design on both the top and bottom made layering easy, with thumb loops that slid easily into jackets. Testers loved the extra-wide waistband that provided support and fit smoothly underneath ski pant buckles (though we noticed some stretch after each wear, and opted to wash and dry these layers more frequently to maintain their shape over time). Throw a vest over the patterned design, and you\u2019ve got a killer apr\u00e8s outfit. While warmth earned high marks, versatility was a bit lower. We found the Saga kit to be a hit during December and January, but on sunny days in late February and March, we reached for lighter layers.<\/p>\n

Best for the Wool-Sensitive<\/strong><\/h2>\n

Helly Hansen Lifa Merino Midweight Graphic Top and Pant<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Merino wool, polypropylene<\/p>\n

Pros and Cons<\/strong>
+ Two-layer construction ideal for wool-sensitive people
+ Excellent moisture management
+ Flat seams are chafe-free under other layers
\u2013 No thumb holes<\/p>\n<\/section>\n

Helly Hansen\u2019s two-layer LIFA merino tech, which sandwiches an internal synthetic layer with an external merino layer, allows folks who are wool-sensitive to experience the material\u2019s benefits. The result was a hit among our testers, who uniformly felt that LIFA\u2019s combination of warmth and breathability made this the ultimate women\u2019s base layer for any winter activity where big temperature swings make staying warm and dry essential.<\/p>\n

While testing this set in regions ranging from the Northeast to the Tetons, testers agreed that the LIFA Merino Midweight crew top and bottom provided warmth on lift rides and windy summits but also wicked moisture extremely efficiently. One tester who happened to have it on while digging out her snowed-in van was impressed with how dry she stayed throughout the physical exertion. For folks wanting even more ventilation, HH makes a zip-neck version for quickly dumping heat.<\/p>\n

Warm, breathable, quick drying, this is the lightweight zip-t you\u2019ll be reaching for all season. This fleece pullover is perfect for cool mornings and versatile enough to act as a mid-layer in colder conditions. It\u2019s also durable and water resistance to keep you protected from the elements and dry all day long. Layer it with anything, wear it in any conditions, and never miss a beat on the trail.<\/p>\n<\/section>\n

Best 3\/4 Bottoms<\/strong><\/h2>\n

Ortovox 185 Rock\u2019N\u2019Wool Short Pants<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Merino wool<\/p>\n

Pros and Cons<\/strong>
+ Lightweight
+ Hits at boot-top
+ Excellent movability
\u2013 Runs a little short<\/p>\n<\/section>\n

A tried-and-true three-quarter option, Ortovox\u2019s 100 percent merino Rock\u2019N\u2019Wool bottom gives you the barely-there feel you want during a hard-charging tour or in-bounds hike. They were the go-to women\u2019s base layer for one tester who wore them all season, storm-skiing to spring touring, and appreciated the breathability, loose fit, and not having to maneuver ski socks around them. These are a lighter-weight bottom, and some testers who run cold found that they preferred a burlier base layer on the coldest days but picked these out of the pile on high-exertion outings and in temps of about 32 degrees F and above. It\u2019s worth noting that if you have long legs, the bottom cuffs might ride up a bit.<\/p>\n

Best Lightweight<\/strong><\/h2>\n

Le Bent Women\u2019s Featherweight Hooded LS Crew<\/strong><\/h3>\n

Sizes:<\/strong> XS-L
Key materials:<\/strong> Bamboo, merino wool, nylon<\/p>\n

Pros and Cons<\/strong>
+ Extremely versatile
+ Hood adds protection
\u2013 No XL size<\/p>\n<\/section>\n

Ski touring can feel like a temperature rollercoaster, and a lightweight base layer is typically the safest option. Le Bent\u2019s Featherweight Hooded LS Crew has been available for a few seasons now, and no matter how many layers we try, we find ourselves returning to this women\u2019s top time and time again. Testers took this lightweight, stretchy, stink-resistant top to Chamonix, British Columbia, and Hakuba, Japan.<\/p>\n

Built with a blend of bamboo, merino, and nylon, this hoodie draws the best of everything from each fiber, with a smooth and luxurious next-to-skin feel. \u201cI typically run cold, but get super hot with big efforts,\u201d said one tester after a trip to Canada\u2019s Selkirk Mountains. \u201cThis was my primary layer for a weeklong backcountry lodge trip in BC. A typical day was eight hours and 5,000 feet with lots of stopping, so temp control was key.\u201d<\/p>\n

We used the hood plenty while touring along windy ridges, and the relaxed fit was comfy to lounge in for lodge life. Our only complaint was the size run\u2014most base layers for women we tested offered sizes up to XL, though this layer only goes up to a large.<\/p>\n

Key materials:<\/strong> Merino wool, Tencel, nylon, spandex<\/p>\n

Pros and Cons<\/strong>
+ Transitions between technical and casual
+ Super warm
\u2013 Too warm for ski touring<\/p>\n<\/section>\n

Whether we were chasing early ups on a storm day or lounging around the house on a rest day, Stio\u2019s Alpin PeakWool Midweight Hoodie got plenty of mileage. Built from a blend of merino, Tencel, nylon, and spandex, this women\u2019s base layer struck a luxurious balance of warmth, stretchiness, and breathability. \u201cI\u2019d recommend this hoodie for anyone who skis midwinter,\u201d said one tester after a season in the Sierra. \u201cIt\u2019s comfortable and warm, and the combination of wool and smooth weave lets you forget you\u2019re wearing technical clothing.\u201d Though it felt a little too warm for a ski tour, we loved the cozy, relaxed fit for kicking back at the lodge after a big day on the hill.<\/p>\n

Wild Rye Bassett Half Zip and Legging<\/strong><\/h3>\n

Sizes:<\/strong> 0-18
Key materials:<\/strong> Merino wool<\/p>\n

Pros and Cons<\/strong>
+ Wide size run
+ Super breathable
\u2013 Fair amount of stretch after wears<\/p>\n<\/section>\n

For yurt life, ski tours, and chasing our pals around the hill, we loved the cozy feel and breathability of the Wild Rye Bassett Half-Zip and Leggings. \u201cMy winter uniform,\u201d reported one tester in Jackson, Wyoming, after a season of backcountry and resort skiing in the Tetons. Merino wool with a touch of spandex offered all the warmth, breathability, and odor resistance we could want out of a winter layer. The only downside was that we noticed a fair amount of stretch after each wear, and we found ourselves re-shrinking them in the dryer frequently.<\/p>\n

PAKA Women\u2019s Thermal Crew<\/strong><\/h3>\n

Sizes:<\/strong> XS-XXL
Key materials:<\/strong> Royal Alpaca fibers, merino, Tencel<\/p>\n

Pros and Cons<\/strong>
+ Warm but not heavy
+ Odor-resistant
+ Form-fitting
\u2013 Expensive<\/p>\n<\/section>\n

When it comes to base layers for women made from natural fibers, merino is by far the most readily available. But times are changing: bamboo has made an appearance over the last few years, and now alpaca is making its way onto the scene.<\/p>\n

PAKA\u2019s base layers are made with 40 percent Royal Alpaca fibers combined with 40 percent merino and 20 percent Tencel for stretch and comfort. Testers expected the Thermal Crew to be a little coarse, so they were pleasantly surprised to find otherwise. \u201cThis alpaca is super soft and very cozy,\u201d commented a Jackson, Wyoming\u2013based tester who wore it throughout the season in mild to moderate conditions. \u201cI\u2019ve tried others that are scratchy and itchy but this feels like a nice sweater.\u201d<\/p>\n

In addition to the top\u2019s natural odor resistance, testers appreciated how the ribbed construction allowed it to hug curves without being too tight or restrictive. Consider PAKA if you\u2019re wool-sensitive, but still want a warm and comfortable natural fiber top for pretty much any winter pursuit.<\/p>\n

Skida Viska UPF Sun Hoodie<\/strong><\/h3>\n

Sizes:<\/strong> XS-XL
Key materials:<\/strong> Polyester, Lycra<\/p>\n

Pros and Cons<\/strong>
+ Fun pattern
+ Highly breathable
\u2013 Only for super warm days<\/p>\n<\/section>\n

A fun patterned base layer for passionate spring skiers, Skida\u2019s Viska UPF Sun Hoodie became a solid corn-harvesting companion during April and May, when we just couldn\u2019t bear to hang up the ski boots. \u201cWhy not add flowers to every ski day?\u201d said one tester after a slushy day at Crystal Mountain in Washington. Made of polyester and Lycra, this women\u2019s base layer is all about breathability, ideal for those 50-degree F days when you might<\/i> ski in a bikini but know you need that sun protection.<\/p>\n

How to Choose the Best Base Layer for Women<\/strong><\/h2>\n

When shopping for women\u2019s base layers, consider how they will perform when you\u2019re out in the wild. First and foremost, are they comfortable? These are your next-to-skin layers so they need to feel good on your body. Are the seams compatible with backpack straps? Does the hem work well with your ski pants? Does the half-zip, button-up, mock neck, or crew neck satisfy your style? Are you looking for something to wear during long days of uphill travel in the backcountry, or will you be spending the day riding chair lifts?<\/p>\n

Merino wool fibers are naturally odor-resistant, moisture-wicking, and breathable, but generally less durable as synthetic materials. Because synthetics are usually a blend of fabrics, they are popular with those keen on stretchiness and moisture management. It\u2019s better to buy something that is thoughtfully designed and durable rather than something cheaply made that might fail you on the mountain. Beyond the technical details, you may also want to determine if what you are buying is sustainably produced. Most reputable brands have information about their sustainability practices available on their websites.<\/p>\n
