The Sea to Summit Ascent -9°C/15F down mummy sleeping bag redefines the meaning of versatile. In colder temperatures you can pull down the technical hood, close the draft tube protected zips and let the 750+ Ultra-Dry goose down keep you warm.In warmer temperatures, the triple-zip Free-Flow Zip system allows you to open the zip in different configurations for excellent ventilation. On warm nights, you can even open the Ascent -9C sleeping bag completely to turn it into a quilt. You can also close the snap fasteners in the shoulder area, open the zip of the foot box and 'wear' the Ascent like a piece of clothing when camping. All this makes the Ascent a true three-season backcountry sleeping bag - one of the few commercially available.
