Oh man. The kids set these up at our last campsite, and they really, really enjoyed them. They're generously sized, and seem to be made of parachute-like material- thin, but very strong. They were a BARGAIN at the price, although I would highly recommend getting tree straps for them, as the original ropes aren't all that great. The hammocks themselves, though, are wonderful, and I would buy them again, if we needed more hammocks for camping.
