Collection: Men's Baselayers

Men's Baselayers

These long johns, pullovers, and more aren't just an important part of your system, they're the foundation. The breathable moisture transportation of your entire system starts at ground zero with these selections. Sweat is wicked directly off the skin and then breathed out and up as vapor, moving its way to your next layer and eventually into the air beyond. Choose the ideal next-to-skin choice for your system and enjoy sweat-free performance.
