Description

One bag to rule them all. This ingenious multi-flap design means that you really get three bags in one. With the blue topper zipped on, its good down to 40 degrees. With the yellow, its good down to 20 degrees. And with both of them its good down to 5 degrees. I used it in the cold wintertime mountains of Rocky Mountain National Park, sleeping in 5 degree ambient temperatures on top a foot or so of snow. It works.
