An alpine fact: Sweaty leads turn into cold belays. Designed to manage the extremes of high output exertion in cool to cold conditions and to 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 face that glides easily under layers. Details include a brushed elastic waistband and a gusseted crotch with a functional fly. Made of a 5.4 oz Polartec Power Dry 100% polyester double knit, with Polygiene permanent odor control. Fabric is bluesign approved.
