REI® Down Time provides great warmth for its weight, plus excellent durability and compressibility--ideal for mountaineers and backpackers. Cover and lining 100% Nylon. Plumb/Black Plumb/purple color shows best in 4th and 5th pictures. This bag has original New tags on it so it may be a pre-owned non-used bag even though tags have taken a beating from being in storage and moving (Genuine Military Surplus-previously owned by soldier). Sewed on tag got caught and ripped moving in our facility.
