Some of the best days are the sweatiest-like when you start full throttle in the morning and end wandering by headlamp to find the trailhead. We make our Capilene Lightweight, our lightest-weight, fastest-drying and best-wicking baselayer, for days like this. The fabric’s subtle grid pattern sits lightly and comfortably on the skin, while the smooth outer face glides easily in any layering system. Highly breathable for high-exertion and warm conditions, the fabric is 100% recycled polyester with Polygiene permanent odor control. Features include a self-fabric collar with internal neck tape for chafe-free comfort, full underarm gussets for unhindered shoulder mobility, flatlock seams that minimize chafing, offset shoulder and side seams that lie smoothly beneath pack straps, and a drop tail for additional coverage. Fair Trade Certified sewing.
