This belt set is not what I used it for. I have 9.4 ounces on my scale (including carrying case). The sling part must prevent damage to the tree trunk. In my experience, that's half true. The system works by tying knots in the rope and attaching carabiners to the loop you make around the tree. If you tie more knots for different positions, be careful. As I was packing my hammock, I noticed knots banging against the tree due to my weight (200 pounds). These knots are extremely difficult to untie once tied, as the weight of your body pulls them tight while you are in the hammock. I would advise potential buyers to look for chain straps instead to avoid damaging trees or whatever you tie to your hammock. Also, the straps are nylon, so they will sag over time, forcing you to tie more knots. It's not that much in the long run. I give this product 2/5 stars for the lackluster design, but it will work if the above doesn't bother you. or if you have big hands to untie those knots :) AJSmith
