If there’s one thing we’ve learned from Wisconsin winters, it’s that you don’t skip your base layer. That extra bit of warmth can be the difference between feeling mildly annoyed by the cold ... and feeling like you just got hit by an ice-nado. More than just feeling warm, though, we want you to be comfortable. So we developed a fabric that’s significantly stretchier than the stuff we’ve offered in the past. The extra give provides a more natural, flexible feel that makes it virtually disappear. And since the last thing you want to be is damp when it’s cold, Thermaskin™ technology pulls moisture away from your skin to keep you comfortably dry, too. This is one base layer you don’t want to skip.
