When you picture thermals, 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: Thermals!
Step One Viscose has nearly 2x the permeability of standard cotton underwear.

Keeps you warm, dry and wicks sweat AWAY from your body
Our thermals have all the same incredible features as our boxers, with the added benefit of keeping you warm and comfortable all day long. Wear them to the snow! Wear them around the house! Wear them to the office that your boss insists on keeping at 0 Degrees all day long!
