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. This weave is made with 82% recycled yarns, some of which contain material from discarded fishing nets. This band is carbon neutral. The Sport Loop contains 45% recycled content by weight, 100% of manufacturing electricity is covered by clean energy, and 50% or more of all carbon neutral Apple Watch products are shipped without airplanes.

The Ocean Band is molded in a high performance elastomer with a tubular geometry allowing it to stretch for a perfect fit, even over a wetsuit. The corrosion-resistant titanium buckle and adjustable loop secure the band during high-speed water sports. For extra length, an extension band is sold separately — perfect if you need extra length to wear the band over your wetsuit.
