<p>A sleeping bag that 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 adjustement may be accomphished quickly and easily via one or more secondary external zippers (5, 10) or a system of toggles and loops (20), allowing the sleeping bag user to respond to even sudden changes in temperature.</p> |
