They are way better than bungee cords. I use them to secure a bag to my motorcycle when touring. There are no hooks to scratch anything or “bend loose” as they secures with a loop in the strap itself. They are easy to use: attach, buckle, tighten.
When I first saw them at a motorcycle show, I thought yes, they are cool, but they are kind of pricey. I put it on my Christmas list and have used them this past riding season including several multi day trips. I now think they are easily worth it. They have uses beyond the motorcycle world… think anywhere a bungee would be used.
They offer several sizes for different applications. I use the model that adjusts between 18″ and 60′. It’s one-inch wide.
