I have a real cheap but very large hammock.
It is made out of nylon twine fish net, about 1/2 inch square mesh. I think the total size is about 30 feet 8 feet. It is used in layers in the hammock for increased support. There os plenty of cord for tying it up.
It is (I admit) an odd way to make a hammock. However it rolls up compact and it is not very heavy. It dries out fast if it does get wet too.
