Made from a custom high-performance fluoroelastomer with compression-molded perforations for breathability, the Nike Sport Band is durable and strong, yet surprisingly soft. The smooth, dense material drapes elegantly across your wrist and feels comfortable next to your skin. An innovative pin-and-tuck closure ensures a clean fit. See Dimension section below for band sizing information.
