A breathable, lofted baselayer to keep you warm in cold conditions. Patagonia Women's Capilene Thermal Weight Zip Neck is made from Polartec® Power Grid® fabric, with HeiQ® Pure odour control - it has a smooth face for easy layering. This fabric’s open-grid pattern next to skin provides superior warmth, breathability and moisture-wicking performance.  Offset shoulder seams eliminate chafing under pack straps and the long center-front zipper vents body heat and is backed by kissing welts for low-bulk comfort next to skin.
