Reflective Guy line set is easy to use and thoughtfully designed to be stronger than steel. It will support your weight easily and won’t damage the trees you use as anchors. This strong sling works with any hammock with carabiners. Simply wrap it around the tree, pick the setting on your tree sling, and clip your hammock into place. Use it with the Firefly Hammock by Una Caminata Sports for a setup that is quick and easy and feels like a dream to relax in.
