If you're going to buy only one top, this should be it. What distinguished this top from other base layers in our test, though, was its comfort and fit: Our lankiest testers applauded its long sleeve and shirt length, which kept their wrists and backs covered. It managed to fit correctly and look good on testers of different shapes and heights. The microweight fabric—made of merino wool yarn spun around a nylon core—was particularly soft and durable compared with the competition. Heat and vapor were able to escape quickly during movement, especially in comparison with the synthetic Duofold base-layer top we tested.
Everything we recommend Our pick. Do your clothing and the planet good by washing your base layers only when they need it. We also thought about ethics in the manufacturing process.

- The colder months can be pretty darn brutal, but sometimes staying bundled up next to the fire isn't an option.
- You can thank us later.
- Our experts tested these bottoms on a wide array of adventures and across a spectrum of environments and temperature ranges, from fall river trips in Utah to winter trail runs, hikes, and climbs in the Rockies to wind-blown ridgelines in the Cascades.
If you're going to buy only one top, this should be it. What distinguished this top from other base layers in our test, though, was its comfort and fit. Our lankiest testers applauded its long sleeve and shirt length, which kept their wrists and backs covered. The microweight fabric—made of merino wool fibers spun around a nylon core—was particularly soft, non-itchy, and durable compared with the competition.
Heat and vapor were able to escape quickly during movement, especially compared with the Hot Chillys and Duofold base layers we tested.
Because it breathed so effectively and offered UPF 30 protection, testers were able to wear this base layer as sun protection with the sleeves rolled down even on warmer days. It performed equally well layered under jackets for skiing in Colorado, and it stayed warm when it got wet in the moist Pacific Northwest.
In our tests, the stretchy, velvet-soft fabric kept the shirt from riding up during movement and made this top ultra-comfortable. Multiday backpackers and testers who did not wash it after a single wear complained of odor, too. The thick waistband stays up without digging into your belly or rolling over uncomfortably, and the fabric is soft and stretchy without the plasticky feeling of other synthetic base layers.
We found it genuinely worth the cost for the fit. We had to pry it away from our testers. With a stay-put fit rivaled only by our top pick, this US-made base-layer bottom sacrifices some stretch and softness for a better price.
These natural-fiber long johns reduced stink and fit our bodies better than others. The workhorse of base-layer bottoms, the Icebreaker BodyfitZone Zone Leggings were among the best of the bunch in our tests. Plus, merino wool has natural anti-odor capabilities—and for us, it worked.
In addition, I interviewed Justin Lichter and Shawn Forry , the first and only people to hike the 2,mile Pacific Crest Trail in the winter, and pioneers of several 1,plus-mile treks in places like New Zealand and the Himalayas. In the offseason, Lichter is a ski patroller and Forry is an associate director for Outward Bound. At the time of our interview, Noland did not represent any of the companies we considered, but she has since gone on to represent Trew.
She told us which features distinguished notable base layers in her two decades of public relations and outdoor experience. We also picked the brain of designer Outi Pulkkinen from Duckworth to learn how fit could impact the performance of a base layer.
Lastly, we talked with Robert Thomas no relation to the author of this piece , senior apparel product line manager at Smartwool, who talked to us about base-layer fit and core-spun yarn technology.
The best base layer for you will be the one that fits the dimensions of your body and has a design that you are comfortable wearing. That way you can stay warm whether you are working up a sweat, sitting around the campfire, or occupying that cold transition time in between. We perused blogs and customer reviews for dozens of brands, ultimately deciding on the best model from each brand based on the reviews.
To supplement what we read, we talked to dozens of outdoor-garment buyers to get their opinions on what they used in the backcountry. The inclusion of Lululemon might surprise you, but we had found that many John Muir Trail hikers all women were trying to stretch their dollar by using yoga wear as a base layer on the trail.
This is a phenomenon documented by REI, which featured a blog article suggesting that yoga-style pants will work for about 50 percent of people enjoying the outdoors. Because many outdoor enthusiasts look to stretch their buck by choosing activewear that works indoors, outdoors, and as a style piece, we wanted to test whether yoga wear could hold up to the standard outdoor-apparel competition. When we began picking models to test, we eliminated those made with cotton and cotton blends immediately.
While such pieces work well enough as thermals when dry and are good at wicking, cotton is not an effective insulating layer when wet either from sweat or rain. Worse yet, cotton takes so long to dry that it makes wearers feel colder than if they were wearing nothing. By banning cotton from our review, we cut out common brands like Hanes and Fruit of the Loom the least expensive options available. We then concentrated on brands and performance fabrics meant for outdoor exercise.
We also included several brands better associated with fashion or athletic wear than with the outdoors, such as Under Armour, Cuddl Duds, and Uniqlo. For this guide, we leveled the playing field by testing items with as similar design features as we could find read: basic crewneck, long-sleeve tops without frills. Last time, we tested base-layer tops with all sorts of elements—hoods, half-zips, thumbholes in the cuffs, and pockets.
By testing lightweight layers, we were able to better determine which fabric had the best warmth-to-weight ratio versus which one was simply the heaviest. With our chosen layers in hand, our seven testers hiked, skied, snowboarded, mountaineered, and climbed their way through four months of testing. Nearly all of our testers had thru-hiked a 2,plus-mile trail at minimum—an experience that requires living in the same base layer from four to six months—so they had opinions.
They subjected a few of our top-ranked base layers to hundreds of miles of use on similar trips. Some lived and worked in base layers, while others loved layers for casual hiking and day-to-day wear. Our testers took these base layers to extremes in Colorado, California, Oregon, Washington, Japan, and Florida why not?
Fit: Long johns keep you warm by trapping heat in the small gap between your skin and the base layer. The key is to make sure that gap is the right size.
Winter-adventuring duo Justin Lichter and Shawn Forry suggested that a base layer should have a relaxed form fit—trim enough to layer over without being bulky. It should not hang off loosely from any part of your body.
A tighter fit can constrict circulation, so the body feels colder. Exposed skin: We asked testers of varying heights and body types whether the design of the layer left any body part feeling naked. Comfort: Does the fabric feel soft, stiff, or plasticky and wetsuit-like? Does it allow a full range of movement? Is it scratchy? Does it make you itch? Some base layers up their breathability with mesh-like panels in key hot-spot areas, such as the armpits.
Wicking: In addition to allowing water vapor to escape through breathable fabric, base layers help the body regulate temperature by wicking moisture drawing it away from the skin and spreading it to a broader surface area to evaporate faster.
Wickability depends a lot on fit. There is nothing in the fiber that gives it that feature. They need a treatment. When a manufacturer treats these fibers on the outside of the garment with a hydrophilic or water-loving topical treatment, the synthetic fabrics start attracting water away from the skin and toward the outer layer of the fabric.
Hydrophilic treatments absorb water and disperse it to a greater surface area to reduce evaporation time. These treatments turn the synthetic fabric into a moisture-wicking layer but can wash out of the garment over time. The better your layer wicks, the less cold you will feel from sweat when you stop being active. Drying time: Once moisture has wicked away from your skin and into the fabric, it should disperse across a wider surface area to help the layer dry out faster.
We tested drying time by running all the layers through the wash and hanging them up. We ordered the layers based on how moist they felt right after the spin cycle. Then, every five minutes, we rearranged the order based on moistness until all the layers were dry, recording how long each layer took to attain dry status.
Temperature: This one seems obvious, but it can be a little tricky because a base layer needs to keep you warm in a variety of temperature-changing situations.
Base layers work by switching from a wicking layer when you are active to a thermal layer when you are taking a break in the cold. They also need to work during the transition time in between. Odor: Wool has natural antibacterial features. Style: Is the piece stylish enough to wear alone, or do you always need to wear this underwear under something else? Can it work as an athleisure or athletic-lifestyle fashion accessory in addition to a performance piece? Value for price: High-end and high-price base-layer fabrics include cashmere, mohair, and alpaca wools.
These materials tend to have higher tensile strengths, feel less itchy, and be less absorbent. We kept our eyes peeled for American-made long johns, as well as companies that offered recycling or take-back programs for used gear.
We also thought about ethics in the manufacturing process. It creates a warm microclimate, like a thin, personal temperature-regulated bubble. So the other job of a base layer—besides warming and cooling—is to wick sweat away from your skin to keep you from feeling chilled.
Which fabric makes the best base layer is an age-old debate in the outdoor sphere. Blends aim to the capture the benefits of each one, but also have their drawbacks. Wool fibers are naturally stretchy, which makes the fabric feel formfitting and look flattering on a wide variety of people.
Unlike synthetics, merino wool naturally wicks sweat away and breathes well after all, sheep use it to regulate their temperature, too. If a spark jumps out of your campfire, the wool layer will resist it better than the synthetic which will likely melt. Synthetic-merino blends aim to get the benefits of both fabrics while offering a high-quality base layer at a good price. Of course, these blends often also come with the negative features of their parent fabrics—odor retention, reduced insulation, and long drying times.
Our top pick, the Smartwool Merino , is constructed of an 87 percent wool and 13 percent nylon fabric made of a yarn constructed of merino wool spun around a nylon core.
We reached for blends when doing endurance activities like backpacking and mountaineering because we wanted the thermal qualities of wool plus the durability of synthetic. The Sustainable Apparel Coalition created an index to rank the environmental friendliness of various fabrics used in outdoor clothing, including base layers. It takes into account the social and labor impacts of outdoor wear, as well as the life cycle of the piece including what happens to it after it wears out.
The process of manufacturing base layers—regardless of how sustainable it is—leaves an impact on the environment. The SAC also tracks the ethics and labor-supply policies of outdoor-apparel companies. Brands that use wool in their base layers have been criticized for sourcing from farms with reported animal-welfare issues. Meanwhile, the relationship that outdoor-apparel companies have with their labor and suppliers is an ethical issue for both synthetics and wool, because regardless of the fabric, someone has to sew these garments.
The International Trade Union Confederation Global Rights Index can be a source of information about the work conditions the sewers face based on where the garment was constructed or where the fabric was woven at the country level.
If environmental, ethical, or animal-welfare concerns influence how you shop, be sure to read up on the brands highlighted in this guide. Some people are allergic to wool. Others may find synthetics scratchy. Look for a fabric that feels soft and that has a texture you like. Made from merino wool spun around a tough nylon thread core, this machine-washable and machine-dryable, odor-resistant shirt is a practical choice if you want to own only one base-layer top.

Ski long underwear. Why You Should Trust Us
Synthetic fabrics are notorious for being smelly. The polyester fabric dries extremely fast but doesn't quite breathe as well as merino layers. Being such a lightweight fabric these are not made for deep winter ventures but are perfect if you need a versatile and comfortable pair of longies to accompany you on outings in every situation but deep cold. Overall we are extremely impressed with the quality, comfort, fit, and unbeatable price of these bottoms!
If you read the review for the SmartWool Merino top you know how we feel about this fabric! These bottoms balance extreme warmth and breathability with grace and comfort that is worthy of praise.
Built for the coldest conditions but wicking away sweat and breathing so well that they perform just as beautifully when the temps warm up a bit. Flatlock seams and a wide merino covered waistband offers all-day comfort. With a bonus of merino's natural anti-odor abilities, you don't have to worry about making a stink after a long hard day in the hills.
These bottoms tend to stretch out after use which we don't love. The fabric will recover from its stretch after a wash but washing them less means they will last longer. Although the comfort is heavenly the fit could use some fine-tuning, especially the crotch.
The infamous long underwear crotch sag still lives on in these bottoms. For there not to be an extra pocket of fabric below your crotch, the impressively comfortable waistband must be worn above the belly button.
These bottoms are perfect for those working or playing in extreme cold conditions and anyone that needs a versatile layer that can not only perform in warm and cool weather but also proves itself in bitter temps. Read review: SmartWool Merino Bottom.
Outdoor Educator and guide Roland Mott authors this review, bringing the experience and attention to detail that only comes from a life avidly spent engaged in a variety of outdoor activities often spent wearing long underwear. Roland earned a degree in Outdoor Recreation Leadership in and has guided rivers, backpacking, and climbing for 12 years throughout the US and Central America. He currently co-directs wilderness courses for a Colorado-based experiential education program.
Finding out what long underwear model is best among a large group of contenders started off with internet searches and hours spent reading reviews. Like many products we test, the protocol involved a combination of field use and lab tests. Aspects like warmth, comfort, and fit were evaluated primarily while wearing the underwear in a variety of outdoor settings, while durability and breathability were best served with lab tests, such as the 8-inch granite abrasion test we devised for testing how well the garments resisted abrasion.
Long underwear, or base layer, bottoms play an important role in keeping you warm out in the cold and regulating your body temperature while you're crushing in colder conditions. Bottoms aren't used as frequently as tops but when you need them, they're a lifesaver and quite versatile too. Wearing them as tights while trail running, layered under your favorite pair of jeans for a night out, or underneath a technical shell ice climbing and skiing, they are a non-negotiable layer for colder activities.
Related: Buying Advice for Long Underwears. We tested bottoms across a range of activities, temperatures, and environments to understand how they stacked up to one another across four metrics. If you're a mountaineer, go on multi-day ski tours, love winter camping, or just spend a lot of time recreating in cold conditions, investing in a high-end level is easier to justify. However, if you're looking for a pair to slap on under your ski pants for something cozy next-to-skin for some resort laps, you can keep the price range lower.
Just don't drive your price line so low that you reach for cotton bottoms — we don't recommend those. Our Best Buy Award winner from REI Co-op is a totally fine pair of bottoms that are at home walking the dog on cold winter days and carving up groomers on skis, and the price is very reasonable. We don't recommend buying this type of product used to save a few bucks, but hey, you do you.
A bottom's ability to keep you warm stems from a few factors: the thickness of the fabric, yes, but also its ability to breathe and wick sweat away from your body keeping you dry and comfortable across a diverse range of activities and temps. To provide you with an accurate review of how warm these bottoms are compared with one another we made sure to test them in a wide range of situations. Working up a sweat skinning steep terrain, walking the dog in freezing temps, winter hiking and backpacking, and sleeping through the long dark cold nights.
Things to think about are: what temperature range will you be using them for, what intensity of activity will you be engaging in, do you want versatility across seasons, do you naturally run cold or hot, or are you wearing them under a technical hard shell layer, like ski pants, that traps heat well and isn't super breathable?
Breathability is a quality that can make or break how effective a base layer is at regulating your body temperature, keeping you warm in the cold, cool when your busting chops, and dry and comfortable through it all. A garment's ability to breathe lives in the fibers of the fabric. Breathability is the capacity of the fiber to move heat induced moisture or perspiration from the inside of the garment, transferring it to the outside, and then allowing it to evaporate.
This process keeps you from overheating and allows the bottoms to stay dry when you're working up a sweat which all adds up to comfort while moving and relative warmth throughout a range of body and outside temps.
Our temperature doesn't fluctuate as intensely on our bottom half as it does on our top half, but it is an area that is good at producing consistent heat. To test breathability we skinned up windy ridges, ran icy mountain trails, and wore bottoms in boiling hot huts a little too much stoke in that wood burning stove right before bed, buddy.
In addition to never taking them off for months except to occasionally shower, we also performed a controlled test in the lab.
One at a time and in a temperature-controlled, indoor environment, we work up a sweat with the same short but rigorous exercise routine, consisting of pull-ups, push-ups, mountain climbers, burpees, and jump squats while wearing each base layer. We then time how long it takes for our skin to dry after stopping. All the merino layers we tested are great at breathing, a natural quality and benefit of merino, but the two mentioned stood out above the others with their ability to breathe, wick away sweat, and dry quickly next to your skin.
Long underwear bottoms are historically notorious for a poor fit. The days of yore gave us no choice but cotton longies that were baggy had a waistband that stretched four sizes by the end of the day, and a crotch that darn near reached your knees.
Well, the wild west days of long johns are gone and we've entered an era of functional design and technical materials. Comfort is a metric that is reasonably uniform across different users but fit is very objectively based and differs wildly between varying body shapes, sizes, lengths, and types.
We try to give you an idea of how a garment generally fits so as to not have a bias to any one body type, but with that being said, we always suggest trying things on in-person to see if they fit you well.
Armed with a long list of skeptical inquiries, we broke down the comfort and fit of each to equip you with the best knowledge of how comfortable and well fitting these bottoms are. We'll let you know if they fit too baggy like your JNCO pants in middle school or too snug like that one time, also in middle school, you tried on your sister's pleather tights while she wasn't home you didn't think we knew about that, did ya?
Both with a simplistic design, great mobility, super comfortable fabrics, and a thoughtful fit these bottoms wear like a second layer of skin. The SmartWool Merino blasts the roof off of comfort with their beloved weight soft cush merino wool and super comfy waistband but has a bit of what we refer to as SCS Soggy Crotch Syndrome.

Last Updated on October 16, When it comes to ski and snowboarding clothing jackets and pants are definitely the glamour products. What you put next to your skin while you are on the slopes can make a huge difference to your enjoyment of your sport. Researching the best thermals for men can be so confusing with multiple materials, features and prices.
There are great products out there if only you could find them. Cutting through the complexity is what this guide is about.
There are three main fabrics to choose from. Merino wool , synthetic , and blends. Each has benefits you might favor. Merino is warm, light and breathable.
The antimicrobial quality of merino wool means that it suppresses bacteria and body odor. The thermal effect of this fabric makes it perfect for cold environments. Synthetic fabrics are hard wearing and effective at wicking moisture away from the body.
This keeps you dry, regulates temperature and is comfortable. Some synthetic fabrics have ant-bacterial treatments added to them to prevent odors. There is another option. Blends of synthetic fibers and merino wool offer comfort and performance. These fabrics usually come at a premium price.
How warm your base layer is, depends on the weight of the fabric used. Best for mild weather and less severe conditions.
They offer a balance between warmth and breathability. When skiing or boarding you might find them a little warm if you are exerting yourself in milder weather. They may keep you warm on the ski lift but you may find them too much when working hard on the slopes. The alternative to selecting one thickness of thermal underwear is to use layering. The best base layer for skiing combined with a mid layer provides warmth, breathability and the option to remove a layer if necessary.
You will, therefore, expect it to last. Be prepared for some differences in the durability of the products on offer. Merino is really soft and comfortable but it does wear and can develop small holes. Synthetics will last longer and you should expect several seasons of good performance, making them one of the best thermal underwear materials to choose from.
Zips, fit and style are things you might think are merely personal preferences for clothing that is generally not seen. You should think carefully about how they affect the comfort and performance of your base layer. For a base layer to be effective as insulation it needs to be a snug fit. This also helps with wicking moisture away from the skin.
You might regret it when the weather closes in on the mountain. There are no shoulder seams and the flatlock seams throughout mean no chafing. Some have reported that this mens thermal underwear has helped maintain healthy body temperatures in low points down to F.
This means it slides easily on anything you layer over it but wicks really well on the inside. The thumb loops keep your sleeves down and hands covered.
The added odor control is a nice feature. The taller collar is warming and the zip means you can ventilate if needed. The structure of the weave promotes wicking and stretch. There are lightweight panels to help thermal regulation.
Use it as a base layer for skiing or on its own for general outdoor use. It has good length in the body so stays tucked in.
Great for colder conditions with wicking capability too. The soft interior traps warm air and keeps you dry. One thing you need when snowboarding or skiing is full movement. Added layers can sometimes feel constricting but these leggings stretch four ways. With a convenient fly and elastic waistband built for comfort, they are a solid pick. This is a quality made product with non-itch wool. Boring but important. They are easy to wash on a wool setting in a washing machine with a liquid wool detergent.
They dry quickly too. Come aboard the pirate ship and be a part of the crew. Get the latest info and deals on skiing and snowboarding equipment.
