Abstract
A sleeping bag allows users to adjust the bag between a conventional rectangular bag and a narrowed mummy-style bag, thereby adjusting the internal volume of the bag. This allows a user to reduce the inner air space of the bag forming a tapered mummy-style shape for maximum comfort in cold weather. The sleeping bag user may also expand the inner space of the bag into a non-tapered, substantially rectangular shape for maximum comfort and freedom of movement in warm weather. This adjustment may be accomplished quickly and easily via one or more secondary external zippers or a system of toggles and loops, allowing the sleeping bag user to respond to even sudden changes in temperature.
