It holds up My 285lb frame along with the Haven safari Hammock Tent! Amazing. It is difficult to undo once you’ve used it. I find that just getting the tension off it between uses and it is easy to move back and forth again. ### ⭐⭐⭐⭐⭐ Works as advertised *by S***. on February 2, 2025* Like the easy set up of the hammock. ### ⭐⭐⭐⭐ Whoopie straps *by A***R on July 26, 2026* This works really good once you learn to use it weights almost nothing packs small takes a bit to learn to use it especially if you tighten it down to much took two people to undo it when I over tightened the hammock with it. I finally figured out how to use it works really good I recommend this to anyone looking for whoopie straps.
