Unisex. New never worn. For your cold-weather treks, heat and water-repellency go a long way to making you forget the chill. We went to Iceland to research and develop gear that can handle those frigid conditions. The result? The head-to-hem coverage of this warm and relaxed puffer jacket, made with at least 75% sustainable materials, using a blend of recycled polyester and recycled nylon fibers.
