The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 41mm and 45mm Apple Watch models, and were offered in sizes to fit 130–200mm wrists (41mm) and 145–220mm wrists (45mm).
This 2023 version of the Midnight color was a single shade of black (the previous 2022 version was a multi-color stripe design). The connector plastics matched the black color of the band, and closure plastic was putty.
Apple described 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.”
