versatile hammock
I pack this and a tarp into my motorcycle panniers when I go touring as it takes up very little space when packed. The double liner means you can slot an air mattress in between to keep your back and bum warm on those colder nights. It works great as a bivi too except you still need to rig up a tarp to keep the rain off. Once you get used to lying in a hammock across the diagonal, this thing is more comfortable than most beds.
