My NECKSTRAP is a unique application of climbing rope that is simple, comfortable and rugged. The climbing rope is soft and absorbs shocks. My 9mm thick NECKSTRAP will accommodate up to 5 lbs of camera and lens. Mounting is quick and easy with steel ring mounts. Adjust length to convert to a shoulder mount by tying a knot in the rope. For use on cameras only. Not designed for use in mountain climbing.
