It's a scam. When you look closer, you realize there's a lot of nonsense in the SuperStraps advertisement.
-It's not similar to pulling your backpack forward. It doesn't create that same horizontal force. It creates a vertical force, pulling things together. Exactly like tightening existing straps.
-The load does NOT get distributed over a larger area. Logically, the force is on the inner part, against your body. You know, like your existing straps.
-The foam is similar to the foam you have on your backpack. And if you don't have foam backpack straps, I suggest you buy a new backpack and not these straps. Also, memory foam wouldn't work any better, because it would get squashed by the pressure against your body.
-The benefits assigned to this are the benefits of tightening your backpack straps (closer to spine, better posture). The 27 lbs claim seems to come from thin air.
My advice: just tighten your existing backpack straps! SuperStraps are just another redundant product this company is selling.
I got to use some Super Straps prototypes on several day hikes and I was always surprised with the mount of relief I felt when I activated the arcs. So awesome!
i have had this for about a month now and normally i just have training shoes and a water bottle in my backpack but yesterday went shopping and it absolutely helps.
how ever if you have a big backpack with multiple ways of customizing the straps to your body type then i don't think it will do anything.
