The Patagonia Men'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 your most arctic expeditions. The Polartec® Power Grid panelling system and Polygiene® odor control locks in heat while also letting it escape freely with the moisture and odor that may come with your activities. The tailoring on this crew allows for free movement of arms and also keeps placement of pack in mind-allowing for less strap chafe if worn backpacking. Add this crew to your coldweather collection for superior wicking and warmth!
