These Vietnam issue nylon jungle hammocks work perfect for jungle environments in helping to keep you off of the ground. The damp environment does not lend itself well to sleeping on the ground in a feather sleeping bag. You can also use the poncho liner in combination with the jungle hammock to stay high and dry. This particular style jungle hammock featured special elastic straps that were secured to the ropes that hold the hammock from a tree. These elastic strap work with a small toggle to fit into the grommets on the poncho (not included). The poncho would be positioned above the sleeping soldier to keep the rain off and also to stretch over a mosquito net.
