Patagonia Men's Capilene® 3 Midweight Bottoms
An alpine fact: Sweaty leads turn morph into cold belays. Designed to manage the extremes of high-output exertion in cool to cold conditions and keep you dry and warm beneath layers, Capilene® 3 Midweight is versatile and fast-wicking. Brushed on the inside for warmth, it's soft and compressible and has a jersey exterior that glides smoothly under layers. Details include a brushed-elastic waistband and a gusseted crotch with a functional fly.
