Sleep soundly under the stars with the Mummy Sleeping Bag — a reliable 3-season bag designed for the temperature ranges you will encounter at campsites across Kyushu and western Japan. The mummy shape minimizes dead air space for maximum warmth efficiency, while the contoured hood seals in heat on cold mountain nights. A smooth YKK zipper runs the full length of the bag and can be fully unzipped to use as a blanket on warmer evenings. Packs down into the included compression sack to a surprisingly small size that fits easily in any backpack.
