With the Apple Watch 38/40mm Silicone Watch Strap Nike Sport Platinum/Black, you can happily 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 38mm and 40mm and fits around a wrist of 130 to 200mm.
