This Nike Sport Loop Apple Watch band was released in Fall 2019. 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 “Royal Pulse/Lava Glow” and appears light gray on a black background with flecks of light blue and link. Nike Apple Watch styles tend to use more abstract descriptions of colors than Apple designs. In this case, the “Royal Pulse” description likely refers to the light blue threads, while the “Lava Glow” threads are likely the pink threads. Inside, the Apple WATCH | Nike logo and the 44mm size is set in bright green.
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.”
