Apple 46mm Ultramarine Sport Loop

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 yarn, some of which contains material from discarded fishing nets.
This strap 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 aeroplanes.
