Abstract
A sleeping bag constructed such that its outer circumference is greater than its inner circumference includes additional integrated protuberances, or space fillers, that are added to the interior lining of the sleeping bag to fill-in around the sleeper's body. Making the circumference of the outside of the bag greater than the inside maintains the thickness of the insulation in selected areas. To maintain insulation thickness at other locations around the sleeper's body, the insulation-containing space fillers are incorporated into the interior of the bag and expand under the influence of the insulation to fill-in around the sleeper for reducing the internal volume of the bag. This construction can be carried the length of the sleeping bag.
