This Nike Sport Loop Apple Watch band was released in 2018. 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. Style names have included Bright Crimson/Black, Pearl Pink, Smokey Mauve, Midnight Fog, Celestial Teal, Cargo Khaki, Black/Pure Platinum, Black, Summit White, Desert Sand/Volt, Pink Blast/True Berry, Royal Pulse/Lava Glow, and Summit White. This example is Olive Flak. Most Nike styles tended to use an “interpretive” word in addition to a color, while Apple styles were arguably more concise, color-focused names.
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.”
