Whether you're getting out for a winter hike, running errands or even feel a chill at home, some days you just need a base layer. They're made with innovative fabric that generates heat by absorbing body moisture. These pants give you an extra layer of warmth that's made to move with you, thanks to the thicker, buttery soft jersey fabric and just-right stretch. Plus, they're lightweight and bulk-free for a smooth and easy feel under other pants. And with a moisture-wicking fabric finish, you'll stay warm AND dry.
