Nomad sport strap Apple Watch 38 / 40 mm grey The Nomad sport strap gives any Apple Watch a modern and sporty look, while being perfect for intensive workouts and everyday use. The sport band has a lightweight and breathable design, made from a soft, flexible fluorocarbon rubber for extra comfort. Fluorocarbon is a fluoroelastomer that is antimicrobial and can be easily cleaned with soap and water. The material provides the ideal balance between comfort and durability. Thanks to the internal ventilation channels at the bottom, the wristband is breathable. The pin closure provides a firm grip. Both the aluminum pin and the sports band itself are waterproof and therefore require no special maintenance. Whether you train at home, swim or jog - the sport strap can withstand all sporting challenges.
