My harness system seems to be pretty inefficient. It consists of a wrap around belt with buckle (similar to the actual buckle) with suspenders that go over my shoulders and connect to the jet pack via black snap things. This seemed like it would work fine originally, but after a day of conning last year, my back was torn up. There is way to much stress placed on the shoulders and upper back, while the bottom of the back rests on my butt and scrapes my back. Do you guys have an attachment at the bottom of your back to the belt of the harness? There has to be some way to even out the weight.
