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.
