The Patagonia Women's Capilene Thermal Weight Crew is great paired with a fleece and waterproof shell for any frigid activities. Meant for layering, the thermal weight can be worn for cold ski days, back country trips in winter conditions, or even the most arctic expeditions. The Polartec® Power Grid paneling system and Polygiene® odor control locks in heat while letting moisture escape freely during more active moments. The tailoring on this crew is gender specific, allows for free movement of arms and also keeps in mind the placement of your backpacking pack for less strap chafe. Add this crew to your cold-weather collection for superior wicking and warmth!
