Extra-wide mummy with windproof, highly water-resistant shell; 15° F.

Don't let a little claustrophobia keep you from getting into a mummy bag; everything about the Western Mountaineering Badger Gore Infinium is built for comfort. The 15-degree Badger is a mammoth 66 inches wide at the shoulder and 41 at the foot, and this girth is kept in line with a warm down-filled collar that provides a barrier against convective heat loss and a full-length insulated draft tube along the zipper. The hood is cut large and fills around your face without having to be cinched tight. On top of all that, the Badger Gore Infinium has a highly water-resistant/breathable shell for extreme weather protection. This shell is the most water-resistant, windproof, and breathable fabric suitable for sleeping bags.

Like all of Western Mountaineering's bags, the Badger is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.


The GORE-TEX INFINIUM™ WINDSTOPPER® series enhances quality and performance, combining versatile aspects of support and comfort without the need for total waterproof protection. Durable water resistance combined with increased breathability, better packability, and optimized lightweight elements are the defining features of this technology. GORE-TEX INFINIUM™ WINDSTOPPER® is totally windproof and provides highly water-resistant protection for unstoppable performance.
