With the Apple Watch 42/44mm Silicone Watch Strap Nike Sport Anthracite/Black, you can wear your Apple Watch while exercising. The strap is made of fluoroelastomer, which is a durable material. The strap is strong, yet soft and flexible at the same time. The holes in the strap provide more ventilation, so your Apple Watch stays around your wrist comfortably during exercise. Thanks to the pin closure, the end of the watch strap doesn't protrude.
This original Apple watch strap is suitable for Apple Watch 42mm and 44mm and fits around a wrist of 140 to 210mm.
