The Apple Watch Sport Band is crafted from a custom, high-performance fluoroelastomer that is remarkably durable, strong, and surprisingly soft, featuring a smooth, dense material that drapes elegantly across your wrist for all-day comfort. Designed specifically for active use, this lightweight and sweat-resistant band utilizes an innovative pin-and-tuck closure system to ensure a secure, clean fit during workouts or daily wear, while the medium/large (M/L) size configuration offers a versatile fit for wrist circumferences typically ranging from 150mm to 210mm. | Refurbished Excellent | | Watch Band FIT Apple 45MM M/L | Red | Best Buy
