Made with compression-molded perforations for breathability, the Nike Sport Band is durable and strong, yet surprisingly soft. It features colorful flakes that create a randomized pattern, making each band completely unique. The smooth, dense material drapes elegantly across your wrist and feels comfortable next to your skin. An aluminum pin-and-tuck closure gives the pin a fresh matte finish. This band contains at least 30% recycled fluoroelastomer, with each flake containing at least 66% recycled fluoroelastomer.
