Why We Like The Western Mountaineering Puma GORE-TEX INFINIUM Sleeping Bag

Designed to conquer extreme weather conditions across different terrains, the Western Mountaineering Puma GORE-TEX INFINIUM Sleeping Bag is our top pick for sub-zero temperature mountaineering and camping.

With its ample room and exceptional insulation, it surrounds us with baffle construction, interlocking draft tubes, a draft collar, and a hood that are filled with a generous amount of 37 ounces of premium, 850+ fill power goose down.

This sleeping bag is also wider than most mummy bags, making it suitable for larger individuals and offering enough space to protect delicate equipment from freezing overnight.

Designed to withstand temperatures as low as -25F, this winter mummy bag allows us to pursue our mountaineering and cold weather camping adventures with confidence, thanks to the reputation of Western Mountaineering for using high-quality materials and expert craftsmanship.
