Frequently bought together:


The Western Mountaineering Puma Infinium -25F Degree Down sleeping bag is what you want when it all gets real, on a high-altitude mountaineering trip. The 850+ fill power down lofts this bag to a full 9", for a warmth rating of minus 25 below! Few mountain ranges require anything warmer than the Puma Gore Infinium, and you'll be happy to have this portable furnace when you really need it.
