Description

When you picture Long Johns, what springs to mind? Itchy, thick fabric? That weird bunching thing that always seems to happen around the crotch? Butt sweat? Yea. Us too. That’s why we’ve reinvented them. Introducing our newest addition to the Step One fam: Long Johns!

Step One Bamboo has nearly 2x the permeability of standard cotton underwear.
