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