Abstract: A sleeping bag that allows a user to comfortably sleep on their side without their sleeping bag twisting or otherwise hindering their ability to rest and sleep. The sleeping bag has an increased amount of insulation in one or more of the hip region, the shoulder region, and the footbox as compared to the torso region and the leg region. The sleeping bag may have two different types of insulation in the region having the increased amount of insulation versus one type of insulation in the other areas of the bag.
Abstract: A sleeping bag that provides a user a greater amount of room, on demand, within the interior of the sleeping bag by including at least one expandable panel. The expandable panel has an “open” position and a “closed” position. In the open position, the panel is expanded providing an increased girth and interior volume to the sleeping bag, compared to when the panel is closed. The expandable panel may have a reduced amount of insulation compared to the rest of the sleeping bag.
