Summary

             

Great for early season or mobile hunting.



           

 





A good pair of thermal underwear should keep you warm whether you’re working outside, braving the early morning cold on a run, camping in the backcountry, or hitting the slopes on fresh powder days. I live in Wisconsin, where winter temps can hit brutal lows, so having a solid pair of thermal underwear is critical, especially since I spend most of my time outdoors. While some options are rated for different temperatures and activities, the best thermal underwear for men should keep you warm and dry under all conditions.









Things to Consider Before Buying Men’s Thermal Underwear





Long johns, base layers, thermal underwear, or whatever you call them, their purpose remains the same—keeping you warm and dry. Thermal underwear keeps you warm by trapping your own body heat close to your skin to provide a warming effect, even when the temps drastically drop. And a material’s ability to wick moisture ensures that you’ll stay dry in the sweatiest or wettest conditions.





co*panies typically make thermal underwear from wool, synthetic material, or a blend of the two. And depending on your activities, some might be better suited than others for specific outdoor adventures. Other than a pair of the best hiking shoes, a great pair of thermals might be the most important piece of gear you buy for outdoor activities in the cold.   





Wool 





Wool, especially merino wool, is one of the best materials for thermal underwear. It can absorb up to 30 percent of its water weight and remain dry during cold, wet conditions. However, thermal underwear made from low-quality wool tends to be itchy and ineffective at wicking moisture. And depending on the temps or your activities, wool might be too warm for your specific needs.  





Synthetic





Synthetic thermal underwear usually features a blend of polyester or nylon. These synthetic blends typically have excellent durability and moisture wicking capabilities, and I actually prefer a synthetic blend over other materials. These materials also tend to have more flexibility and not restrict your range of motion or movement.  





Weight 





If you want something that’s super lightweight but warm, Wool can sometimes be heavier while synthetic materials usually run lighter. And if you’re counting ounces in the backcountry, lighter materials probably fit the bill better. Oftentimes, however, you sacrifice that warmth for weight. But for most outdoor excursions, the slight weight difference in materials probably doesn’t matter that much, especially if you’re not counting ounces. Depending on your activities, look at which thermal underwear will work best for your needs. 





Fit





Thermal underwear should be skin-tight to keep you warm. Consider thermal underwear brands that offer a slim profile vs a baggy one. The fit should be co*fortable but not too loose. If your thermals fit loosely, they won’t keep out air or warm you as adequately as they would with a tighter fit.  





Cost





I learned quickly that most cheap thermals just don’t cut it when it matters most. There’s nothing worse than shivering to death when you’re on a camping trip, and you realize that the thermals you skimped on are actually making you colder instead of warmer. And if you think there’s not a difference between a high-end set of thermal underwear and a cheap pair from your local dollar store, you’re in for a rude awakening. I’m a firm believer in getting what you pay for, not that there aren’t exceptions to this, but for the most part, warm, moisture wicking thermals don’t co*e cheap. However, when you bite it and take a face and chest-full of snow thirty minutes into your ski day, they’ll pay for themselves.

Why It Made the Cut 





Smartwool’s 150 thermal line offers lightweight, long-lasting performance at a reasonable price. 





Key Features 





  • Slim fit 
  • Flatlock seam construction 
  • 87 percent merino wool, 13 percent nylon core
  • Weight: 6 ounces




Pros 





  • Slim, lightweight
  • Durable
  • Super warm
  • Not restricting
  • Multiple colors and patterns 




Cons 





  • Too warm for some activities




Product Description 





I have been a fan of Smartwool for years. Their products are durable and downright co*fortable, and the 150 line is no exception. Once I slipped the tops and bottoms on, I almost forgot I was wearing them. And I don’t mind wearing these all day. These Merino layers do a fantastic job of regulating your body temperature and wicking moisture. I’ve used them skiing, camping, and hiking in cold temps, and I’m always impressed by how well their profile contours your body and keeps you warm. Pair these with some of the best hiking pants, and you’ll be prepared to face even the most frigid temps outdoors.

Why It Made the Cut 





Whether you’re on the slopes or running on the trails, this thermal top is light, soft on the skin, and moves easily with your body.





Key Features 









Pros 









Cons









Product Description  





As soon as I tried on the Patagonia Capilene Air men’s medium top and medium bottoms, I was immediately impressed by how co*fortable they were. The top felt lightweight with a snug fit, and the bottoms, though form fitting, didn’t restrict any movement. I also appreciated their breathability, especially during long runs.





In colder weather, I noticed these thermals did an excellent job wicking moisture while I ran or biked. Even after sweating and wearing these for several days, I didn’t notice any terrible odor. They didn’t smell brand new, but they didn’t necessarily need washing either.





Best for Extreme Weather: Icebreaker Merino Leggings

Why It Made the Cut 





These warm, excellent moisture wicking leggings are ready to co*bat the coldest temperatures and highest winds. 





Key Features 









Pros









Cons









Product Description 





I have thick, stocky legs, so finding thermals that don’t feel like they’re cutting off circulation often proves challenging. But the Icebreaker 260s fit co*fortably, and I didn’t notice them restrict any movement. These 100 percent merino wool thermals kept me warm on some of Wisconsin’s coldest days, yet they were extremely breathable. While the Icebreaker 260s work great for super cold days, they’re probably too warm for milder temps or super active outings.





Best for Running: Gore Wear R3 Thermo Tights

Why It Made the Cut 





Running and thermals don’t always mix, but these lightweight, moisture-wicking thermals will keep you warm and dry on your coldest, toughest runs. 





Key Features 









Pros 









Cons









Product Description





The minimal profile of the R3s sold me on these thermals. These super lightweight bottoms kept me warm on some of my coldest runs, yet the GoreTex proprietary material wicked moisture and helped me stay dry. While these are plenty warm, they’re not too hot for long, tough runs. Not only does the R3 line excel performance wise, but the thoughtful details like reflective strips, the side pocket on the thigh, and the rear pocket for keys or your phone makes them a no-brainer for running. And the fleece-lining feels like you’re wearing a cloud even on that last mile.





Best for Skiing: Minus33 Yukon Men’s Crew

Why It Made the Cut 





This warm yet flexible construction of Minus33’s thermal makes it an excellent option for skiing, especially those long, snowy days on the slopes. 





Key Features 









Pros 









Cons









Product Description  





As a skier, I prioritize warmth over all else when it co*es to thermals, and these exceed that requirement. They’re thicker than most but also co*fortable and not too snug on the skin. And I’ve never had an issue with mobility while skiing in them thanks to the strategically stitched seams. These Minus33 thermals are plenty warm for the coldest days and co*fortable whether you are carving groomers or plowing through powder. They’re also excellent at wicking moisture and holding scent to a minimum. Even after multiple hard ski days in a row, these thermals didn’t smell the worst. If they have any downfall, it’s that they’re probably too warm for activities that don’t involve snow.

Product Description 





This Meriwool 100-percent merino wool henley makes a great versatile thermal for your camping layers. It’s warm enough to layer for colder temps, yet breathable enough to wear as a standalone piece.





The nice button closure at the top and slim-fit make this a layer you can wear to dinner, whether it’s served at the campfire or restaurant. And the raglan sleeves don’t inhibit any movement. While wearing this thermal, I noticed that it moved with me no matter what I did, and I even forgot that I was wearing it when I wore it as a base layer.

Cons





  • Some might not prefer 100% polyester construction 




Product Description 





I tested these Carhartt thermals on some of the coldest Wisconsin winter days this year. These kept me warm while I shoveled tons of snow and split and stacked firewood. They make an excellent midweight base layer that’s warm and co*fortable to wear. And their 100% polyester construction may not be as warm as merino wool, but they’re highly flexible and designed for constant movement. They don’t wick moisture as well as other options on this list, but they still do an adequate job. But as long as you’re not running, these thermals make an excellent option for long days in the cold.

Why It Made the Cut





For under $30, this synthetic thermal set will keep you decently warm on a budget, and their slim, co*fortable fit makes this feel like a steal. 





Key Features





  • 4-ways stretch fabric 
  • Micro-fleece lined 
  • Top and bottom set 
  • Mix of polyester and elastane fabric
  • Weight: 3.2 ounces




Pros 





  • Warm
  • Snug fit
  • Easy to layer
  • Breathable




Cons





  • Runs small




Product Description 





This best thermal underwear for men packs a price tag that’s hard to beat. Cheap thermal underwear usually fails to keep you warm, runs too bulky, or doesn’t wick moisture as efficiently as it needs to; however, I was impressed by how much warmth these actually provided. And the stretch and microfleece lining make them co*fortable to wear all day. As far as moisture wicking goes, these did an adequate job while I ran in them, but for long distance runs, they might not be the best option.





The TSLAs definitely weren’t the warmest in the test, but that’s to be expected at this price point. While the other options I tested ran true to size, these ran a bit small, and I would suggest sizing up, especially if you have muscular or thick legs. Still, these make a great option for everyday use, and you won’t lose sleep over this price tag.
