This is the single most versatile piece of military hardware ever devised, it's a tent, camo net, water collector, pack, life raft, stretcher, blanket, sleeping bag, raincoat, and hammock. And that is all without the woobie (insulated liner).
"This is a camping tent hammock I made about 20 years ago. It is made of nylon and was stored away from light, which helps explain its good condition. It uses flexible 3/4 inch PVC pipe for the stretcher bars. The curve is adjustable by adjusting the length of the center end rope."
