Men's Thermal Underwear

Get back to basics.

With men's thermal underwear, you're set to take on cold conditions with ease. With both tops and bottoms available, you're sure to stay toasty in any weather. And since they are designed to act as a base layer, you can be sure the rest of your cold-weather outfit will work together with the thermal underwear to offer maximum comfort.

Men's Thermal Underwear Features

While men's thermal underwear obviously is designed to keep you warm, several other prominent features offer added comfort that you can count on.

Stretch fabric offers the ideal fit, keeping the garment close to your skin, while freely moving right along with you. In addition to the stretch component, many thermal underwear fabrics feature moisture-wicking elements. This ensures that any sweat you produce while wearing the items is drawn away from your skin, keeping you dry.

Other essential features to keep an eye out for are SPF or UPF protection, flat seams, odor control, and more - all designed to keep you feeling your best in harsh environs.
