A vented sleeping bag comprising an elongate shell defining an inner volume sized and shaped to receive a user therein. The shell has a head end, a foot end, left and right sides extending longitudinally of the shell, an overlying portion which overlies the user, and an underlying portion which underlies the user. The overlying portion of the shell has at least one vent. A closure is selectively movable between a closed position for closing the vent and an open position for creating a vent opening for ventilating the inner volume of the shell.

What is claimed is: 1. A vented sleeping bag comprising: an elongate shell defining an inner volume sized and shaped to receive a user therein, the elongate shell having a head end, a foot end, left and right sides extending longitudinally of the shell, an overlying portion adapted to overlie said user and an underlying portion adapted to underlie said user; a fastener selectively joining the overlying and underlying portions such that the overlying and underlying portions can be partially separated to allow entry into and exit out of the inner volume of the shell by the user; at least one vent in said overlying portion of the shell located adjacent the foot end of the shell between the left and right sides of the shell; a closure selectively movable between a closed position for closing said at least one vent and an open position for creating a vent opening for ventilating the inner volume of the shell; and a mesh cover attached to the shell for covering the vent opening, said mesh cover collapsing within the shell when the at least one vent is closed. 2. The sleeping bag as set forth in claim 1 wherein the at least one vent extends longitudinally of the shell. 3. The sleeping bag as set forth in claim 2 wherein the at least one vent extends longitudinally from generally about the foot end of the shell toward the head end of the shell a distance corresponding to about 10 to 50 percent of the overall length of the shell. 4. The sleeping bag as set forth in claim 3 wherein the at least one vent is about midway between the left and right sides of the shell. 5. The sleeping bag as set forth in claim 1 wherein the shell further comprises an end panel closing the foot end of the shell. 6. The sleeping bag as set forth in claim 5 wherein the at least one vent extends into the end panel of the shell toward the underlying portion of the shell. 7. The sleeping bag as set forth in claim 1 wherein the at least one vent is defined by adjacent edges of the shell, said edges being separable when the closure is in said open position to create said vent opening for ventilating the inner volume of the shell. 8. The sleeping bag as set forth in claim 7 wherein the shell tapers toward the foot end of the shell when the closure is in said closed position, and wherein said edges of the shell defining said vent are separable when the closure is in said open position to expand the said inner volume of the shell adjacent said foot end of the shell. 9. The sleeping bag as set forth in claim 1 wherein the closure comprises a pair of slide fasteners for selectively adjusting the size and position of the vent opening. 10. The sleeping bag as set forth in claim 1 wherein said fastener is a slide fastener. 11. A vented sleeping bag comprising: an elongate shell defining a inner volume sized and shaped to receive a user therein, the elongate shell having a head end, a foot end, left and right sides extending longitudinally of the shell, an overlying portion adapted to overlie said user, and an underlying portion adapted to underlie said user; a fastener selectively joining the overlying and underlying portions such that the overlying and underlying portions can be partially separated to allow entry into and exit out of the inner volume of the shell by the user; at least one longitudinal vent in said overlying portion of the shell located between the left and right sides of the shell and extending longitudinally of the shell; a closure selectively movable between a closed position for closing said at least one longitudinal vent and an open position for creating a vent opening for ventilating the inner volume of the shell; and a mesh cover attached to the shell for covering the vent opening, said mesh cover collapsing within the shell when the at least one vent is closed. 12. The sleeping bag as set forth in claim 11 wherein the shell further comprises an end panel at the foot end of the shell and wherein the at least one longitudinal vent is partially positioned within the overlying portion and the end panel. 13. The sleeping bag as set forth in claim 11 wherein the at least one longitudinal vent is located about midway between the left and right sides. 14. The sleeping bag as set forth in claim 11 wherein the closure comprises a pair of slide fasteners for selectively adjusting the size and position of the vent opening. 15. The sleeping bag as set forth in claim 11 wherein the at least one longitudinal vent is defined by adjacent edges of the shell, said edges being separable when the closure is in said open position for ventilating the inner volume of the shell. 16. The sleeping bag as set forth in claim 11 wherein said fastener is a slide fastener.
