Abstract: A sleeping bag with an integrated air mattress includes outer and inner shells, an inflatable tube grid, insulation, and means for selectively inflating the tube grid. Both the outer and inner shells have inner and outer surfaces, and each defines an opening. The inner shell's outer surfaces are positioned adjacent the outer shell's inner surfaces, and the inner shell's opening is aligned adjacent the outer shell's opening. The tube grid defines a plurality of grid cavities and is sandwiched between the outer and inner shells. Insulation is positioned in the grid cavities and sandwiched between the outer and inner shells. When the tube grid is inflated, the user may enter the sleeping bag through the inner shell's opening. To pack the sleeping bag, the tube grid is deflated, causing the tube grid and insulation to shift from an expanded to a compressed configuration, taking up a minimal amount of space.
