A parachute silk hammock, can lay sideways or lay long and roll-up in it.
W/hammocks you reallyneed something under you as the wind moving will make your backside freezing cold!

I'm adding a light-weight (kind of pricey) tarp to use as a rainfly for it. I also have 1 woolblanket and 1 wool/poly blanket mix that would make a night out comfy.
I also have a tube tent, a couple 60gallon white baggys and maybe some 80gallon (i forget I just know they are huge). And I have lots of paracord to make al ot of stuff.
A couple space blankets to use as wind shields, and maybe a few other things.
