Sea to Summit Ascent 15

Sea to Summit says:
Ascent Down Sleeping 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.
