Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability. When you buy the (PRODUCT)RED Sport Loop, we will now send a contribution to the Global Fund to fight COVID-19. Your support can make all the difference.
