I bought this bag specifically for using in deep cave systems which are notoriously wet and maintain a constant temperature ranging from 35'-50' depending on the cave system. After having read the other reviews disputing the bag's 0' rating, I decided this bag would probably be adequate for my intended use. To ensure this, I decided to do several test runs in the open outdoors. I used the bag on three separate campouts, one in which I was dry with outdoor temperatures of 25' F, one in which I was damp at 32' and another in which I crawled into the bag soaking wet at 45' after subjecting myself to mild hypothermia (shivering for 30 minutes). Each of these three experiments offered a warm, comfortable night. In each of the trial runs I was wearing polyester long johns. Next I intend to do a test run at 32 or lower soaking wet.
