The soft and compressible Patagonia Women's Capilene 3 Mw Crew provides excellent insulation and ultimate comfort next to the skin. It is one of the most versatile and fastest-wicking performance base layers, it stretches, dries quickly, and resists wear. It is brushed on the inside for warmth, with a jersey exterior that glides smoothly under layers. Crew details include a self-fabric collar, raglan sleeves with underarm panels for mobility and a tuckable hem.
