The Patagonia Capilene Midweight Bottoms are excellent medium-warmth baselayers for wicking sweat and staying toasty during high-output activities like skiing, snowboarding, and adventures in cold weather. They are so comfortable that you might find yourself wearing them as pajamas and around town. HeiQ Fresh technology means you have some protection against the inevitable odors that start to build up in your layers after spending all day working up a sweat.
