Peak Design Mobile Cuff Wrist Strap (M-WPS-BK-1), Black

A slim, secure wrist strap that keeps your phone or small camera close without getting in the way.

Mobile Cuff provides drop protection for your phone, point-and-shoot camera, or any small device with a strap or lanyard connection point. The Micro Anchor™ connection system lets you attach and remove your device easily while keeping it secure and tangle-free.

The basket-woven nylon/poly rope balances strength, padding and stretch. In the event of a drop it cinches onto your wrist. An aluminium stopper lets you set your preferred minimum loop length.

Integrates seamlessly with the built-in strap connection points on Peak Design cases and Apple iPhone cases (17 and onwards). Also works with any point-and-shoot camera or small device with a strap or lanyard connection point. An included universal adapter enables compatibility with almost any third-party phone model or case.

Spare Micro Anchors are sold separately.
