An alpine fact: Sweaty leads turn 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 the most versatile of our performance baselayers. Brushed on the inside for warmth, these bottoms are soft and compressible and have a smooth knit face that glides smoothly under layers. Details include a flat mesh-backed waistband and a gusseted crotch. Made of 5.4-oz Polartec® Power Dry® 100% polyester double knit, with Polygiene® permanent odor control. Fabric is bluesign® approved.
