The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. They were available for the 38/40mm and 42/44mm 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 Pomegranate Sport Loop uses two shades of pink as base colors with the edges in a pale pink. The closure and connector plastics are in a shade of pink that matches the lighter pink thread color.
This band’s namesake, the pomegranate fruit, comes from a shrub grown for thousands of years in the Middle East, India, the Mediterranean region, and now across the globe. The exterior of the fruit is the light pink color of this watch band, while the interior features an “inner flesh that’s packed with crunchy, juicy edible seeds called arils.” The arils are red/dark pink and resemble the darker color of the band. The accent color resembles the color of the interior flesh of the fruit that surrounds the pomegranate seeds.
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.”
