Unique early TNF Bivy Sack. Simple construction of one ply rip stop nylon in blue and green. Grommets at the corners for staking down. Not entirely sure if this was the complete unit or if there would have been a tarp or tube tent covering. Good for a layer of wind proofing and would keep your bag clean as is though.
Measures 92″ overall. 76″ foot to neck and 39″ wide.
