For a multiday traverse along the exposed Tonto Plateau, these lightweight baselayer bottoms offer exceptional breathability, stretch and ultrafast dry times. Capilene Lightweight is our lightest-weight, fastest-drying and best-wicking baselayer. The fabric's subtle grid pattern sits lightly and comfortably on the skin; the smooth outer face glides easily in any layering system. Highly breathable for high-exertion and warm conditions, the fabric is bluesign approved, 100% recycled polyester with 35-UPF sun protection and is treated with Polygiene permanent odor control. Features include a flat waistband with brushed inner elastic for next-to-skin comfort, a gusseted crotch for mobility and flatlock seams to minimize chafing.
