The Apple Watch 38/40mm Silicone Watch Strap Sport Pine Green is made of high-quality fluoroelastomer. That makes the watch strap very strong, but also flexible, soft, and light. The silicone strap is made by Apple and will last a long time, thanks to the strong material. The pin clasp, which can be found on the inside of the strap, doesn't protrude at the end of the watch strap. It's concealed nicely behind the silicone strap.
This original Apple watch strap is suitable for the Apple Watch 38mm and 40mm and fits a wrist of 130 to 200mm.
