Marcus Bonna Backpack Straps are made with a long rubberized neoprene pads and Quick-Link endpoints for security against accidental detachment (a Quick Link is a single steel chain link with a threaded nut in the center). Similar to item 128740 (single strap), but these are sold as a pair and feature a snaplink connector in the front that joins the two straps together. This feature, common on camping and wilderness backpacks, makes for better balance and easier carriage. These can be used on any Bonna case with mounts for backpack straps.
Available in these designs:
Note: This model is described in the Bonna catalog as having "caribiner" clips. In the U.S. they are known as Quick-link clips.
