We absolutely had to design a tree friendly solution with our suspension. We used wide polyester webbing to protect the trees you hang from. If you're a nature lover, please don't support the cheap hammocks that come with typical ropes. Ropes bite and rip into tree bark leaving permanent scars and damage. We follow Leave No Trace and each Serac tree strap is designed to be wide enough to protect the trees we love. Keep our forests strong and healthy for the next generation.
