Patagonia's most versatile synthetic baselayer keeps you dry and warm. 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; our Capilene® 3 Midweight is the most versatile and fastest wicking of our performance baselayers. Brushed on the inside for warmth, Capilene 3 is soft and compressible, and the smooth jersey exterior glides smoothly 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® polyester (65% recycled) double knit with Gladiodor® odor control for the garment. Recyclable through the Common Threads Recycling Program.
