MARINER LOOPS To accompany you on your next wild adventure - introducing our MARINER LOOPS. Designed for the Apple Watch Ultra, yet backward compatible with any classic Apple Watch Series 1-11, or SE. The ridged, tubular design, is complete with two methods of fastening your clasps. Pin & Tuck - For those more familiar with a traditional watch clasp, simply fix in the Metal Loop (Keeper) into a the appropriate tubular slot, and remove the C-Hook at the end of the strap. Pin & Hook - If that super secure fit is what you're after, pin it, and hook it. Anchored shut with the C-Hook at the end of your strap, you'll get that perfect fit without compromising comfort. Available in a variety of high-visibility colors to match your gear, the MARINER LOOP is by far, the most versatile band in our range. *Both C-Hook & Keeper are included with the straps. SIZING & FIT 44 / 45 / 46 / 49mm fits wrist 166 - 257mm 40 / 41 / 42mm fits wrist 166 - 257mm
