This Nike Sport Loop Apple Watch band was released in Fall 2020. The packaging described this product as “Hook and Loop Closure Reflective Thread Detail.”
The Apple Watch Nike Sport Loop band has been available in several color combinations that matched one or more Nike shoe or clothing products upon release. This example is called “Obsidian Mist.” Close inspection of the threads reveal that the design is primarily gray thread, but also includes black and green thread. The plastics are all in a shade of gray matching the gray thread. Inside, the Apple WATCH | Nike logo and the 44mm size is set in hot pink.
Apple described the Apple Watch Nike Sport Loop band:
“Soft, breathable, and lightweight, the Nike Sport Loop is designed for fitness, with select colors matched to the new line of Nike running shoes. It features a nylon weave with reflective thread designed to shimmer when light strikes it. A hook-and-loop fastener makes for quick and easy adjustment, and dense loops on the skin side provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability.”
