Mountain Hardwear Bozeman Sleeping Bag

Unlike traditional, restrictive mummy bags, the Comfort Mummy cut offers a slightly more generous fit in the shoulders and hips. It provides the thermal efficiency of a mummy bag while giving you enough room to shift positions comfortably throughout the night.

This bag uses ThermalQ recycled synthetic insulation, which is specifically designed to retain its loft and warmth even when damp. It is a much more reliable choice for humid or wet environments than down insulation, which can clump and lose heat when wet.

Yes. The full-length zipper with double sliders allows you to open the bag completely flat. You can unzip it entirely to use it as a quilt or blanket, or simply unzip the bottom to vent your feet if you overheat.

Yes, this bag is compatible with other bags that feature a similar full-length zipper system. It is a great feature if you are camping with a partner and want to share warmth.

With a comfort rating of 30°F (-1°C), this bag is best suited for three-season camping—spring, summer, and fall. While it has an extreme rating of -13°F, that is a survival limit, not a comfort recommendation, so you will be most comfortable in temperatures above freezing.
