Apple Nike Sport Loop Band Black Nylon, Recycled polyester, Spandex

Redesigned with reflective yarn, the Nike Sport Loop is a soft, breathable and lightweight strap that has a subtle shine. A hook-and-loop fastener and a woven pull tab featuring the Run Swoosh logo make 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.
