This Coleman sleeping bag is water proof unless it is soaking wet. The bag is good for cold weather 10-30 degrees, as shown on the bag, but not for extreme cold. If winter camping is your thing or you are headed for the Arctic Circle, you will want to keep looking. But, for most normal camping use, this bag will keep you warm and dry for a reasonable price. I have spent many nights in this bag and have no complaints about it at all.
