Nike Sport Loop bands use a hook-and-loop fastener plus a woven pull tab for quick adjustments. The skin-side has dense loops that cushion the wrist and help moisture escape for a comfortable, secure fit.

Nike watch bands use hook-and-loop fasteners on Sport Loop styles and pin-and-tuck closures on Sport Band styles; some Sport Bands include an aluminum pin.

Nike bands are grouped by case size. Bands labeled 40mm/41mm/42mm are compatible with one another, while bands labeled 44mm/45mm/46mm/49mm are compatible within that larger-size group.

Some Nike Sport Loop bands reuse excess woven nylon (at least 68% from previous seasons). Certain Sport Band styles and decorative flakes use recycled fluoroelastomer — bands may contain at least 30% recycled fluoroelastomer, and the flakes are reported to contain at least 66% recycled fluoroelastomer.

Nike bands designed for fitness use soft, lightweight, and breathable weaves, dense loops or compression-molded perforations to improve airflow and wick moisture, and reflective thread on some Sport Loop styles for visibility during runs.

Nike bands feature durable attachment anchoring, double-layer nylon weaves with dense skin-side loops for cushioning, and materials chosen to be both durable and soft for all-day wrist comfort.

The colorful flakes are made from recycled fluoroelastomer. Listings note the flakes form a randomized pattern and that each flake contains a high percentage of recycled fluoroelastomer.
