Tree Straps protect tender tree bark by evenly distributing the weight over a wider area while also protecting both the rope and the tree from abrasion. When hanging your hammock from a smooth surface such as a pole or post, tree straps act as a tension belt to prevent slippage. Tree Straps are completely adjustable and are ideal for quick set up and fast take down of your hammock. If there is one thing you get to make your hammock easier to use, this is it. Strength tested for 350 lbs. Includes two straps.
