The Nike Sport Loop has been designed to use excess yarn from previous seasons to create a soft, breathable, and lightweight band with a bold pattern. The hook-and-loop fastener and a woven pull tab featuring the Nike Swoosh makes it easy to adjust on the go. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape.

The Nike Sport Loop contains at least 68% excess yarn from previous seasons, saving over 3 tons of primary yarn.
