The Apple Watch Sport Loop band is woven from nylon thread to create a hook-and-loop closure. They were available for the 38/40mm and 42/44mm Apple Watch models, and were offered in sizes to fit 130–190mm wrists.
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.”
This Flash Light Sport Loop has an overall bright yellow-green appearance. It’s name includes “Light” to differentiate it from a previous Apple Sport Loop color called “Flash,” released in Fall 2017. The original Flash Sport Loop featured bright yellow edges and plastics, but included black thread woven into the center creating a dark yellow appearance, while “Flash Light” consisted only of the light and bright yellow-green hues.
This Flash Light Sport Loop is paired with an Apple Watch Series 7 in silver stainless steel.
