Peak Performance Thermo LJ 220 W

Back by popular demand - Oour lightest, most versatile and breathable base layer. Specifically designed for high intense activities, they fit closely and contain highly wickable ThermoCool that dries quickly and drags sweat away from your body and efficiently pushes it to the next layer. We use these functional long johns as a base layer in early spring when we're out on the trails and know things might get pretty sweaty.
