Made from the same high-performance elastomer as the Ocean Band, this band extension lengthens the 49mm Ocean Band by an additional 50 millimeters - perfect if you need extra length to wear the band over your wet suit. The extension comes with an extra adjustable, corrosion-resistant titanium loop which you can place in any tube to tuck the excess band into. This extension must be used with the regular Ocean Band.

The ultra-thin, lightweight Trail Loop is made from a nylon weave creating a soft strap with increased elasticity for a comfortable fit. The strap is infinitely adjustable with a convenient pull tab for quick adjustments on the go. This strap is carbon neutral. The Trail Loop contains 30% 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.

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.
