The wool is sourced from suppliers who care about animal welfare and meet the Responsible Wool Standard (RWS), which bans the practice of mulesing. The fleece lining provides for additional warmth. Made with polyester recycled from used PET bottles. The knitted headband is stylish, comfortable and warm, whether you’re out skiing, hiking or anywhere else you run into cold, blowing winds. Made with love by a small family business in Germany.
