I read the reviews on this bag before I bought them, so I had some reservations about the temperature ratings and, notwithstanding the guy who insists you should sleep in this bag without warm clothes on, found the bag to be way over-rated for temperature.
While the one I checked out in the local sporting goods store looked to be "OK," I had strong suspicisions about how warm we would stay in this bag when I unpacked them, since after three days they still didn't recover much loft. While I think this is, and will be, a very servicable bag for what we intend to use it for (Scout campouts), we (my son and I) both got cold on our first night using them when the temperature got down to the lower 30s, and that with two layers of warm clothes on inside (maybe I need to try the "no warm clothes option").
The second night, my son used one bag inside the other and stayed warm when the temp got down to 29. The zippers do have a tendency to snag on the fabric, which is frustrating in the middle of the night when one needs to get up. I'm sure I'll learn to avoid that problem with further use, and it's not a problem if you can sleep all night without having a call from nature.
There is also the problem with unzipping the zipper too far when getting out and having the two parts separate (like they are suposed to do if you want to connect bags together). Again, another "problem" that you don't like to deal with when you are already cold, but one that is easily avoided with a safety pin in the right spot.
