  7. The quilt of Claim 1, wherein each discrete quilt fastener element disposed on the inner surface comprises a cord loop, and each discrete quilt fastener element disposed on the outer surface comprises a hook structurally arranged so as to engage and retain a respective one of the cord loops.
  8. The quilt of Claim 1, wherein each discrete quilt fastener element disposed on the outer surface comprises a cord loop, and each discrete quilt fastener element disposed on the inner surface comprises a hook structurally arranged so as to engage and retain a respective one of the cord loops.
  9. The quilt of Claim 1, wherein each discrete quilt fastener element disposed on the outer surface comprises a first snap element, and each discrete quilt fastener element disposed on the inner surface comprises a second snap element that mates with the first snap element of the corresponding quilt fastener element disposed on the outer surface.
  10. The quilt of Claim 1, wherein the set of discrete quilt fastener elements disposed on the outer surface comprises at least one quilt fastener element of a first fastener element type and at least one quilt fastener element of a second fastener element type, and each discrete quilt fastener element disposed on the inner surface comprises a quilt fastener element of the same fastener element type as the corresponding fastener element disposed on the outer surface.

Description

CROSS-REFERENCE TO RELATED APPLICATION 1. FIELD OF THE I NVENTION The field of the present invention relates to sleeping bags. In particular, disclosed herein are various closure arrangements for a sleeping bag. 2. BACKGROUND US4217662 discloses a comforter having a blanket-like body member which is provided with closure members for enclosing a lower portion thereof so that one lower side edge is secured to a corresponding opposite lower side edge and the bottom edge is secured together to define a sack-like robe configuration. A snap fastener is disposed at each upper corner for attachment to associated snap fasteners disposed adjacent to but slightly above the closure member on the side edges so that the upper half side edges can be held in a folded condition to provide a pair of sleeve portions on the body member, each sleeve portion having a predetermined maximum sleeve opening. At least two additional snap fasteners are disposed at intermediate positions on each upper half side edge for securement together to obtain a preselected sleeve opening smaller than the maximum sleeve opening. Preferably, several snap fasteners are disposed along the top edge of the body member for engagement therebetween to enclose the body member around the wearer's chest. 3. SUMMARY A first inventive article comprises a quilt usable as a sleeping bag, first and second pairs of discrete, mating bottom fastener elements, an inner set of one or more quilt fastener elements, an outer set of one or more quilt fastener elements, and a draw cord. The bottom fastener elements are attached to the quilt along the quilt bottom edge; one discrete bottom fastener element of the first pair is positioned between the discrete bottom fastener elements of the second pair, and one discrete bottom fastener element of the second pair is positioned between the discrete bottom fastener elements of the first pair. The bottom fastener elements thereby define a first quilt bottom edge lateral segment between the first pair of bottom fastener elements but not between the second pair of bottom fastener elements, a second quilt bottom edge lateral segment between the second pair of bottom fastener elements but not between the second pair of bottom fastener elements, and a quilt bottom edge central segment between both pairs of bottom fastener elements. The inner set of quilt fastener elements is attached to the quilt inner surface along at least a portion of a linear or curved inner quilt attachment path; the outer set of quilt fastener elements is attached to the quilt outer surface along at least a portion of a linear or curved outer quilt attachment path. The inner quilt attachment path extends from the first quilt lateral edge to the first quilt bottom edge lateral segment and defines on the quilt inner surface an inner quilt- overlap areal segment bounded by the inner quilt attachment path, the quilt bottom edge, and the first quilt lateral edge. The outer quilt attachment path extends from the second quilt lateral edge to the second quilt bottom edge lateral segment and defines on the quilt outer surface an outer quilt-overlap areal segment bounded by the outer quilt attachment path, the quilt bottom edge, and the second quilt lateral edge. With the quilt wrapped in an overlapping footbox-wrapped arrangement, (i) the outer quilt-overlap areal segment faces a portion of the quilt inner surface, (ii) the inner quilt-overlap areal segment faces a portion of the quilt outer surface, (iii) each quilt fastener element of the inner set is substantially aligned with a corresponding, mating quilt fastener element of the outer set, and (iv) engagement of the corresponding mating quilt fastener elements of the inner and outer sets with each other retains at least a footward portion of the quilt in the overlapping footbox-wrapped arrangement. With the quilt wrapped in the overlapping footbox-wrapped arrangement, (i) the first pair of mating bottom fastener elements is positioned so as to engage each other, (ii) the second pair of mating bottom fastener elements is positioned so as to engage each other, and (iii) engagement of the first pair of bottom fastener elements with each other and engagement of the second pair of bottom fastener elements with each other retain at least the quilt bottom edge in the overlapping footbox-wrapped arrangement with the first and second quilt bottom edge lateral segments overlapping each other. The draw cord is engaged with the quilt bottom edge. With the quilt retained in the overlapping footbox-wrapped arrangement by engagement of the first pair of bottom fastener elements with each other, engagement of the second pair of bottom fastener elements with each other, and engagement of the corresponding quilt fastener elements of the inner and outer sets with each other, pulling the draw cord gathers the quilt bottom edge to form a closed, wrapped footbox of the sleeping bag. A second inventive article comprises a sheet adapted f
