Description
Our most versatile sleeping bag available. In colder temperatures you can cinch down the technical hood, zip up the draft-tube protected zippers, and allow the 750+ Ultra-Dry Goose Down to keep you warm. In warmer conditions, the Free-Flow Zip system lets you unzip in different configurations for superior ventilation and even open flat to turn the Ascent sleeping bag into a quilt on the warmest of nights.
All of the above make the Ascent a true three-season backcountry bag. Close the snaps at the shoulders, open the footbox zipper, and wear the Ascent at camp—hardcore adventures don't have to be hard all the time.
