The Cap Air Hoody from Patagonia we believe to be one of the comfiest and warmest base layers in the market. The blend of merino wool and polyester allows moisture to wick away from the body, dries quickly and resists odour. All of Patagonia's virgin wool is certified to Responsible Wool Standard.

• Fine merino wool from New Zealand blended with Capilene® recycled polyester for enhanced warmth balanced with improved wicking durability and dry time
• 18.5-micron-gauge yarn; lofted-wool innovation
• Fabric stretches and is soft against skin
• Seamless 3-D construction eliminates chafe points through the entire garment and has almost no wasted material
• High collar and seamless hood with anatomical shaping for warmth
• Soft stretchy elastic knit in cuffs and hem for added recovery and comfort over extended use
• All of the virgin wool Patagonia sources is certified to the Responsible Wool Standard (RWS) to help ensure protection both for the animals that supply it and the land they graze
