"We must, indeed, all hang together or, most assuredly, we shall all hang separately." - Ben Franklin
I remember a post for DIY "netted hammock"...
So, now just get some paracord or fire retardant rope and weave your own.

-Are you doing a 5lbs. survival trip in Canadian winter?
-What kind of temps are you anticipating with your "survival trip"?
