For the photographer/birdwatcher carrying a heavy camera or binoculars, the SUPER CLASSIC STRAP is a great option. It has the same tailored design as the popular CLASSIC STRAP; however, it adds the patented internal control-stretch system found in S.O.S. Strap in addition to Non Slip Grip. This combination is ideal for the individual wanting a narrower strap design that has the needed strength and comfort features required for handling a heavy load. A choice of two popular connection options are available. SUPER CLASSIC STRAP is sure to please!
