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. | Apple | | 49mm Ocean Band | Natural Titanium | Neon Green | Best Buy
