Ascent Women's Down Sleeping Bag In colder temperatures, cinch down the technical hood, zip up the draft-tube protected zippers and allow the 750+ Ultra-Dry Goose Down to keep you warm. As temperatures rise, unzip the Free-Flow Zip system for additional ventilation or completely unzip to be a quilt for use during the extra warm nights. The Ascent sleeping bag is one of very few true three-season backcountry bags available. You can even close the snaps at the shoulders, open the footbox zipper and wear the Ascent at camp giving you real freedom on your backpacking adventures.
