The Lockstraps G3 (the third generation) are 8.5-foot-long straps that come with tough carabiners, combination locks, and a strong sliding clasp. The Lockstraps G3 are built with braided stainless-steel cable that's embedded between double nylon straps. The steel, heat-treated carabiner locks use galvanized steel rivets. As tough as they are, Lockstraps also are made to be soft enough to not scratch your gear. You can set your own personal combinations on either carabiner. $40 to $45 each.
