Technical warmth-retaining construction and high-lofting down, room to sleep comfortably, and unmatched ventilation make the Ascent sleeping bag an incredibly versatile backcountry bag.
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 up 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, one of very few on the market. 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.
