The Western Mountaineering CloudLite 15° Sleeping Bag is an ultralight down sleeping bag designed to deliver excellent warmth and comfort without adding unnecessary weight to your pack. Rated to 15°F (-9°C) and weighing just over two pounds, it features premium 850+ fill-power goose down and fully baffled construction with 5.5 inches of loft to maximize heat retention and eliminate cold spots during cold nights in the mountains. The wide-cut semi-rectangular design provides extra space from shoulders to feet, making it a great option for side sleepers or anyone who prefers more room than a traditional mummy bag. An ultralight 12D ExtremeLite™ shell fabric offers a balance of durability, breathability, and water resistance while maintaining exceptional packability. Additional features such as a full down collar, insulated draft tube, and dual full-length YKK zippers help seal in warmth or allow the bag to open flat and function like a backcountry comforter, delivering spacious comfort and high-performance insulation for demanding backcountry trips.
