What is claimed is:
1. Sleeping bag comprising inner and outer shell layers formed of thin, highly flexible, substantially non-elastic fabric, baffle fabric means extending therebetween defining a plurality of separate compartments therewithin, and a plurality of portions of a highly resilient insulating fill material having the characteristics of down contained within said compartments urging separation of said inner and outer shell layers, defining an insulated bag-like structure extending from a neck opening, wherein said inner and outer shell layers within a shoulder encompassing region are non-differentially cut and seamed generally curvalinearly extending medially across the shoulder region between the side edges of the bag and the side edges of a neck opening to define a contoured shoulder portion enabling the outer shell to be fully lofted thereat by pressure of the fill material away from an occupant's shoulders while the inner shell is lofted inwardly thereby to self-adjustably accommodate to the shoulders of such occupant and wherein said inner and outer shell layers, said shoulder encompassing region and a foot encompassing region are differentially cut enabling said outer shell to be fully lofted from said inner shell so that body pressures against said inner shell produce minimal compression of the fill thereat.
