If this bag worked properly, it would be awesome! The flex construction is fabulous for my flailing sleeping body. The problem is the zipper. Once you tuck yourself into it, zipping it up is a bit tricky. It often gets stuck on the up-zip.
But the major problem is unzipping the bag. As a claustrophobic type of person, being trapped inside my bag is not pleasant. The zipper requires a lot of pushing/pulling/yanking before it will move. And then it will go down a short distance before getting stuck again. I have had friends try to get me out and they have the same problem. I have sent mine in for warranty because it is pretty lousy to sleep in.
