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 Dark Cherry/Forest Green band used a two-stripe design first introduced in Fall 2021. One stripe was “Dark Cherry,” a shade of dark red, and the other was “Forest Green,” a shade of dark green. The edges were pale melon and provided a striking contrast to the dark stripes. The connector plastics were dark red—a similar shade to the “Dark Cherry” color—and the closure plastic matched the pale melon color of the edges.
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.”
