The Sport Loop is soft, breathable, and lightweight. Its hook-and-loop closure allows for quick and easy adjustment. The two-layer nylon fabric has a dense weave on the inside, providing soft padding while allowing moisture to escape. The fabric is made from 82% recycled yarns, some of which are derived from discarded fishing nets. The Sport Loop contains 45% recycled materials by weight. 100% of the electricity used in its production comes from clean energy sources.
