I purchased this as a sleeping bag liner to hopefully keep my filth out of my bag and make it last longer. I also liked the addition as it felt more like having a blanket than with just the sleeping bag, but I'm a big baby like that. I've read reviews about these type of liners bunching up and getting tangled, but I didn't have any problems. The only thing I wish it had was straps to secure it to the inside of my bag, but I sacrificed that feature because I was going for cheap. It's not anything too special but it fits my needs just fine and I'd definitely recommend it as a nice basic sleep sack for a sleeping bag liner or for traveling.
Bought this to take with me to Europe. Very light love the handy sack it packs in. Comfy enough for being just a sheet. Really warm, pillow fits in it great would recommend if you are just looking for a basic camping sheet or sleep sack.
