A sleeping bag has an elongate shell defining a longitudinal axis and an inner volume sized and shaped to receive a user therein. The shell has a pair of fastener-less arm ports. Each of the arm ports is selectively moveable from a closed port position to an opened port position. Each of the ports has an inner panel and an outer panel. The inner panel is positioned in overlapping face-to-face engagement with the outer panel in the closed port position such that the inner and outer panels are generally in the same plane as the overlying portion. The outer panel is spaced from the inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port.

The sleeping bag of claim 1, wherein the inner and outer panels are generally perpendicular to the overlying portion in the opened port position. 3. A sleeping bag of claim 1, wherein one of the inner panel and the outer panel includes a stiffener. 4. The sleeping bag of claim 1, further comprising a fastener for holding the inner and outer panels in the closed port position. 5. The sleeping bag of claim 4, wherein the fastener comprises a first part disposed on the outer panel and a second part disposed on the inner panel and adapted to engage the first part. 6. The sleeping bag of claim 1, wherein the head end panel, the foot end panel, and the pair of spaced side panels extend between the overlying portion and the underlying portion. 7. The sleeping bag of claim 6, wherein each of the ports is disposed in the overlying portion and spaced from the side panels. 8. The sleeping bag of claim 1, wherein each of the ports in the closed port position forms an angle with the longitudinal axis. 9. The sleeping bag of claim 8, wherein the angle formed by the ports and the longitudinal axis in the closed port position is between about 10 degrees and about 50 degrees. 10. The sleeping bag of claim 1, wherein, in the opened port position, the inner and outer panels are generally parallel to a side portion of the shell. 11. The sleeping bag of claim 1, further comprising a draft curtain attached to the overlying portion and to the underlying portion. 12. The sleeping bag of claim 1, further comprising a draft curtain that extends outward from the inner panel and toward the overlying portion. 13. A sleeping bag comprising: an elongate shell defining an inner volume sized and shaped to receive a user therein, the shell having:an underlying portion adapted to underlie the user during use; andan overlying portion adapted to overlie the user during use, the overlying portion including a longitudinally extending zipper providing user ingress to and egress from the inner volume of the shell, a pair of arm ports being selectively moveable from a closed port position to an opened port position for allowing the user external access from within the bag, each of the ports comprising an inner panel, an outer panel that is separate from and overlapping face-to-face with the inner panel, and a draft curtain attached to the overlying portion and to the underlying portion, the draft curtain being positionable to inhibit air from entering the inner volume in the closed port position. 14. The sleeping bag of claim 13, wherein each of the inner panels are positioned in overlapping face-to-face engagement with the respective outer panel in the closed port position such that the inner and outer panels are generally in the same plane as the overlying portion, the outer panel being spaced from the respective inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port. 15. The sleeping bag of claim 14, wherein the inner panel has a width that is substantially equal to a width of the outer panel. 16. The sleeping bag of claim 14, wherein one of the inner panel and the outer panel includes a stiffener. 17. The sleeping bag of claim 14, wherein the draft curtains are positioned within the inner volume. 18. The sleeping bag of claim 17, wherein the draft curtains are attached to respective inner panels. 19. A sleeping bag comprising: an elongate shell comprising a head end panel, a foot end panel, and a pair of spaced side panels extending longitudinally between the head end panel and the foot end panel, the elongate shell defining an inner volume sized and shaped to receive a user therein, the shell having:an underlying portion adapted to underlie the user during use andan overlying portion adapted to overlie the user during use, the overlying portion including a longitudinally extending zipper providing user ingress to and egress from the inner volume of the shell, a pair of arm ports being selectively moveable from a closed port position to an opened port position for allowing the user external access from within the bag, each of the ports comprising an inner panel and an outer panel wherein at least one of the inner panel and the outer panel has a longitudinal end attached to a respective side panel of the pair of spaced side panels, the inner panel being positioned in overlapping face-to-face engagement with the outer panel in the closed port position, the outer panel being spaced from the inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port, each of the ports being fastener free. 20. The sleeping bag of claim 19, further comprising a draft curtain adjacent each of the ports and selectively positionable to inhibit air from entering the inner volume in the closed port position. 21. The sleeping bag of claim 20, wherein each of the draft curtains are disposed in the inner volume. 22. The sleeping bag of claim 19, wherein the inner and outer panels are generally in the same plane as the overlying portion in the closed port position. 23. The sleeping bag of claim 22, wherein the inner and outer panels are generally perpendicular to the overlying portion in the opened port position. 24. A sleeping bag comprising: an elongate shell comprising a head end panel, a foot end panel, and a pair of spaced side panels extending longitudinally between the head end panel and the foot end panel, the elongate shell defining a longitudinal axis and an inner volume sized and shaped to receive a user therein, the shell having:an overlying portion adapted to overlie the user during use;an underlying portion adapted to underlie the user during use; anda pair of arm ports disposed in the overlying portion, each of the arm ports being selectively moveable from a closed port position to an opened port position for allowing the user external access from within the bag, each of the ports comprising an inner panel and an outer panel, wherein at least one of the inner panel and the outer panel has a longitudinal end attached to a respective side panel of the pair of spaced side panels and at least one of the inner panel and the outer panel extends co-axially outward from the respective side panel, the inner panel being positioned in overlapping face-to-face engagement with the outer panel in the closed port position such that the inner and outer panels are generally in the same plane as the overlying portion, the outer panel being spaced from the inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port. 25. The sleeping bag of claim 24 wherein the inner panel and the outer panel extends co-axially outward from the respective side panel and toward the head end panel. 26. The sleeping bag of claim 25, wherein the outer panel includes a curved surface between the side panel and the head end panel. 27. A sleeping bag comprising: an elongate shell defining a longitudinal axis and an inner volume sized and shaped to receive a user therein, the shell having:an overlying portion adapted to overlie the user during use;an underlying portion adapted to underlie the user during use;a front panel, a back panel, a head end panel, and a foot end panel wherein the head end panel and the foot end panel are attached to the front panel and the back panel; anda pair of arm ports, each of the arm ports being selectively moveable from a closed port position to an opened port position for allowing the user external access from within the bag, each of the ports comprising an inner panel and an outer panel wherein at least one of the inner panel and the outer panel is attached to the head end panel at an intersection of the front panel and head end panel, the inner panel being positioned in overlapping face-to-face engagement with the outer panel in the closed port position such that the inner and outer panels are generally in the same plane as the overlying portion, the outer panel being spaced from the inner panel in the opened port position to define a passage for allowing the user to extend their arm through the respective port.
