Stone Sport Band for Apple Watch 46mm Case - M/L. Purchased this band with an Apple Watch 11 and used it only once. There is one spot of original, hard-to-see dirt. The Sport Band is made from a custom-developed, high-performance fluoroelastomer, making it durable and strong. Yet, it's surprisingly soft. The flexible, high-density material drapes elegantly across your wrist and feels comfortable against your skin. The pin-and-tuck closure is an innovative design that ensures a clean and secure fit. Material: Fluoroelastomer Compatibility: Apple Watch models 44mm 45mm 46mm 49mm Thank you for looking.
