The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 41mm and 45mm Apple Watch models, and were offered in sizes to fit 130–200mm wrists (41mm) and 145–220mm wrists (45mm). The bands also fit older Apple Watch sizes.
This Oat Milk/Lemon Zest band used a two-stripe design first introduced in Fall 2021. One stripe was “Oat Milk,” a shade of off-white, and the other was “Lemon Zest,” a shade of bright yellow. The edges were black and provided a striking contrast to the lighter stripes. The connector plastics were off-white—a similar shade to the “Oat Milk” color—and the closure plastic was black.
Apple described the Apple Watch Sport Loop band:
“Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability.”
