Zenith ALPS Mountaineering

The ALPS Mountaineering Zenith 0° Sleeping Bag is built for serious cold-weather adventures where warmth, comfort, and weight savings are critical. With down insulation, a contoured hood, and a mummy shape, this high-performance bag seals in heat on frigid nights while staying lightweight and packable for backpacking in Rocky Mountain National Park or winter camping near Estes Park.

Designed with an insulated chest and zipper baffle, the Zenith keeps warmth where it belongs — inside your bag. The included compression stuff sack ensures it packs smaller than comparable models, leaving more room in your pack for essential gear. Perfect for mountaineers, backpackers, and winter campers who refuse to compromise on warmth.
