Soft, breathable nylon sport loop bands for Apple Watch, Samsung Galaxy Watch, Fitbit and more. The woven nylon is lightweight and quick-drying, which makes it a favourite for workouts, warm days and all-day wear, and the hook-and-loop fastener adjusts to almost any wrist size for a precise fit.Choose the band that matches your watch model and size — Apple Watch bands fit by case size (38/40/41mm or 42/44/45/46mm), while most Samsung and other watches use a 20mm or 22mm lug. Bands swap in seconds with no tools. Not sure how? See how to change a watch band.
