This shirt is possibly even more of a mid than base layer, that can handle real abuse. An 100% natural fibre ‘active’ base layer that helps to regulate your temperature, insulates even when wet, and wicks moisture form the skin. This base layer brings consistent comfort, as well as reliable warmth and durability, to winter hiking, running and skiing.
