Very thin, Stretchy cotton. Not even as thick as a cheap towel. The best part of it is the wood stretcher and hanging rope harness. I imagine in a month all that will be left is the wood stretcher and the hanging harness. Definately not built to last.
An easy to hang, comfortable and colorful way to enjoy the breeze in your back yard or at the beach if you can find a couple palm trees nearby. I love to enjoy late afternoon sunsets on the lake behind my home between a couple coconut trees. A one person hamnock doesn't put a great strain on palm trees. It is doubtful you'll find a better bargain.
