Your eyes aren't deceiving you – that's an undershirt with a built-in hood and face covering. But that's not even the best part. We reserve that for the fabric: our very own Thermaskin™, purpose-built to keep you dry and warm. All in just the right weight and fit for layering under your everyday looks.
Wear our men’s thermal long underwear shirts when you’re outside in the freezing cold this winter. With these base layer shirts, the temperature won’t bother you when you’re ice fishing, watching an outdoor football game and making snowmen with your kids. Under winter gear, our men’s underwear will keep you warm and dry. The best thermal underwear are also made rugged so they keep up with your every adventure.
These men’s thermal long underwear shirts can be comfortably layered under your casual men’s clothing because they’re never bulky. That means the warm in these base layer shirts are also easy to move in as you ski or shovel snow. Versatile, our men’s underwear moves are essentials when you’re going camping in late fall or going sightseeing on a Winter Wonderland vacation. Just as important, our best thermal underwear is machine washable and resists shrinking.
