The new Nike Sport Loop, made from surplus yarn from previous seasons, is a soft, breathable and lightweight strap with an original pattern. It has a hook-and-loop fastening and a fabric tab with Nike logo to adjust it on the fly. The dense weave of the double-layered nylon fabric ensures maximum comfort against the skin, but allows sweat to evaporate. The Nike Sport Loop contains at least 68% surplus yarn from previous seasons, saving over three tonnes of new yarn.
