Thermal underwear for men can be used for skiing and riding, and even year-round activities depending on the material and weight. We picked the best long underwear that can get the job done keeping your body temperature regulated for anything from a simple dog walk around the block to a week-long winter camping expedition.
The Best Thermal Underwear for Sports
My favorite base layer as of late goes to a new company called Kora. Developed in the Himalayas, Kora yak wool has been the go-to piece of insulation in the high mountains for a heck of a long time. Kora has a great story behind this wool, it’s harvested by nomad families in the Qinghai Tibet plateau in the Himalayas, talk about stuff you can feel good about wearing. Plus Yak Wool is super soft, doesn’t itch and according to Kora, it’s 66% more breathable and 40% warmer, weight for weight than traditional Merino wool.
Fabric: Kora Yak Wool
Fit: Tight, Form Fitting
One of the best lightweight base layers on the list comes from Ridge Merino based in Mammoth Lakes, California. What Ridge Merino offers is a lightweight, breathable piece of gear that can be worn throughout the year. This gear was built for skiers and riders by locals in Mammoth. Ridge Merino is the perfect Merino wool base layer for trail running in the spring, hiking early mornings or for spending a long day skiing and snowboarding.
Fabric: 84% Merino Wool, 16% Nylon
Fit: Form Fitting
The tried and true Patagonia Capline continues to improve year after year. Don’t just think of base layers and thermal underwear for skiing and riding either. Everyone you know should own one of these essential pieces of clothing. What’s great about Patagonia’s Capiline is it works wonders when used as intended as a base layer, yet can double as a nice around the town piece with a great fit that’s not too baggy. Once you experience the temperature regulation that’s offered in Patagonia’s Capilene you may find yourself reaching into your underwear a lot more often.
Fabric: Polartec Power Grid 100% polyester (93% recycled) double knit.
Dahlie Airnet Base Layer
There is no other base layer on earth like the Airnet from Dahlie. What sets this performance long john apart from the pack is its incredible breathability. Thanks to the use of mesh backing the DÆHLIE Airnet is possibly the lightest base layer on the market. Where this piece shines is during high output workouts. If you like to run with a base layer top or bottom throughout the year then you found you’re new favorite piece of gear for training.
The only downside to this piece is it won’t keep you the warmest on super cold days. And the cut is a little more on the European slim side of things. Size up and use the Dahlie Airnet for your next hike, run, cross country ski, bike ride or spring ski tour and you will instantly become a life long fan of this great outerwear company founded by legendary cross country skier Bjørn Dæhlie.
Fabric: 100% merinowoo
Fit: Tight (Go up a size)
Take away some of the fancy features of the Patagonia Capilene and you get your less expensive, fully functional, traditional ski base layer. Made of “super-lightweight” and “high-performance Helly Hansen baselayer material, this baselayer will certainly keep you cool on those long tours, with quick dry-technology protecting you from getting too cold at the end of the day.
For the fair price of 45 dollars, grab this baselayer which is modestly priced and highly functional. This baselayer can be best used for anything from a solid resort pow day to your everyday outdoor activities off the snow such as running, hiking, biking. And camping.
Fabric: HH LIFA
Fit: Form-Fitting to Tight

Here we have, in my opinion, the most bang for your buck. With the turtle neck for extra protection, zip neck for better temperature control, and versatility to be used for anything from a day on the resort to a multi-day trip, this piece is worth your money. If you can only afford one, fair-priced base layer, this is the one to go with.
It may not have the bells and whistles of some of the other brands, but the North Face Long-Sleeve Zip Neck can take you on all different types of outdoor activities for multiple days, for a good price.
Fabric: 63% Polyester, 37% Repreve Recycled Polyester

The midweight long neck is just that coming in camo, rasta, and multiple other colorways, this top can have you feeling comfortable and warm on the hill while also looking good off the hill.

Along with the recycled paper the company uses soy ink and comes in a resealable package.
