Abstract
A sleeping bag includes batts (17, 18) transversely positioned in a shingle arrangement between outer and inner shells (10, 23). The sleeping bag includes a top flap and a bottom flap (11, 12). The batts in the bottom flap are straight, and overlap enough to provide two layers of insulation. A group of batts (17) in the top flap are curved toward the head end of the sleeping bag, and the remaining batts (18) in the top flap are curved toward the foot end. The batts that are curved in the same direction overlap enough to provide two layers of insulation. Some of the batts that are curved in opposite directions are close enough to overlap in three layers in the upper torso area to provide greater insulation where it is most needed. The curved batts provide a more efficient distribution of insulation, without increasing material weight or manufacturing cost.
