Query: Great roomy sleeping bag!

Great sleeping bag, warm and strong. Nice and roomy to move you feet and legs around. I really don't like mummy bags. Enough room I can roll over. My last bag, the zipper broke when I turned over, and that was a good Coleman XL bag...not cheap. The only thing I didn't like about this was that it does not completely unzip all the way around the bag. I like to open them up sometimes and sleep with one open on the bottom and one open on the top. I also like to open them up when I wash and dry them, which I can still do, but the zipper stops at the bottom corner and doesn't open flat. Other than that, it was great. Very warm. So far have only used it in 35 degree weather though, but don't expect a problem in colder weather.
