This sleeping bag is different than I had expected. It's made of a slippery material. However it is large enough to fit 2-3 people,or closes with the pull for one person. Right now,it's still hot here but I think it will do a good job of keeping me warm in the winter. I like that it comes with a pull tie bag to keep it in when not in use,which is fantastic for storage reasons,also is washable which is highly important,especially if you're using it outside.
