Since its not ripstop, when it fails it will really fail hard! Somewhere on the web, some one made a hammock out of silk, sounded pretty good, (except no ripstop) I almost made one, and then happened to come across a hiking journal entry about the silk hammock failing (massive rip) on the 2nd day of a 2 week trip. Needless to say, the hiker was not happy! He spent the rest of his trip sleeping on the ground. I think the key word it "fail safe" !
