For years as a Boy Scout I struggled to keep cool enough in my sleeping bag to sleep well. More often than not, I ended up with the heavy synthetic-fill mummy bag unzipped as far as it would go—to my knee—and my leg closest the zipper outside on the tent floor. It wasn’t until years later—and after many discussions with my wife concerning optimal nighttime thermostat settings—that I realized I was by nature a very warm sleeper. Of course, everything is relative; camping out in Southern California is a completely different game from anyplace that gets truly cold. Nonetheless, my foray into sleeping quilts has proved a remedy to nearly all my outdoor-sleeping idiosyncrasies.
What is a sleeping quilt? Essentially, a sleeping bag with a large part of the bottom removed.
