Picked up a WW2 A-2 sleeping bag for $12.00 today. I've never seen a bag like it. Large enough for two people to easily fit inside, with no zippers just snaps. It spreads out like a down comforter with an od wool blanket liner that snaps inside. Exterior of bag is dirty in places, and looks like it's got signs of bird crap on it in a couple places. Interior is fine, and all snaps are intact. Liner is moth eaten in several places but all in one piece. the tag in the corner reads; Type A-2 Sleeping Bag...Property of Air Force, US Army You fold one half over the other and snap it up, thing weigh
