The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. They were available for the 38/40/41mm and 42/44/45/49mm Apple Watch models.
The Apple Watch Sport Loop band has been available in several styles and colors. This particular design is comprised of a two-tone design with one accent color. This Khaki Sport Loop uses dark khaki brown and dark chocolate brown as base colors with edges in a very light beige. The closure and connector plastics are all in a shade of dark khaki that matches the thread color.
Apple describes 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.”
