en's Stretch Thermaskin Long Underwear Pants

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.
