Although they’re intended for motorcycle and ATV users, I think Piggyback Anchor Straps® would also work well in other applications such as securing things in the back of your pickup. They appear to be easy to use, and are certainly not likely to provide that “smacked in the face by an overstretched bungee cord” effect — which hurts, a lot. Just trust me on that.
This $28 kit comprises two short Piggyback straps, each having two D rings (seen above), two 60″ long straps, and two 72″ long straps. All of the straps are 1″ wide nylon webbing with a loop at one end. Once you’ve tied down an object using the D-ring and 60″ straps, you can “piggyback” another load using the 72″ straps and the second D ring.
Hey, it’s tons better than leaving your gear strung out all over the road.
