Description The Western Mountaineering CloudLite 15Adeg Sleeping Bag is an ultralight down sleeping bag designed to deliver excellent warmth and comfort without adding unnecessary weight to your pack. Rated to 15AdegF (-9AdegC) 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(TM) 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.
