The Best Long Johns for Men

Jeans are great and all, but sometimes they don't cut it. Cold weather is one of those times. When the skies get snowy and the sun goes down, you'll want to turn to thermal underwear — or long johns — to keep you warm. While stiff denim bunches up around your ankles and creates bulk underneath snow gear, man's trustiest tundra-approved clothing stays soft and slim. Many modern long johns utilize moisture-wicking fabrics, and even more of them are fleece-lined to offer extra insulation. We’ve scoured the web for the hottest johns at a modest price, so read on for our shortlist of top-tier long underwear.

Frequently Asked Questions

How tight should my long johns be?

Though this depends on personal preference, it’s generally accepted that thermal underwear should be as tight as possible without restricting mobility. Thanks to the addition of spandex to many modern fabric blends, most long johns are fairly form-fitting, which helps to properly insulate your body from the cold. It may take some getting used to, but tighter johns keep you warmer than baggier ones.

What is “moisture-wicking” fabric and why is it better than cotton?

Moisture-wicking is a fancy term for the way highly absorptive fabrics can soak up sweat and quickly transfer it to the outer layer of the fabric for rapid drying. Though cotton absorbs liquid well, it retains that moisture for a long period of time. Synthetic polyester blends can generally soak up more liquid and dry more quickly. This helps you stay warm even when sweating in low temperatures.
