Apple Watch Ultra band - my husband got this watch for Christmas and got the trail loop band instead. He used this band for 2 weeeks.
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.
