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 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.
