Abstract: A sleeping bag has an elongate shell defining an inner volume sized and shaped to receive a user therein. The shell has a head portion, a foot portion, a middle portion extending longitudinally between the head and foot portions, an overlying portion adapted to overlie the user during use, an underlying portion adapted to underlie the user during use, and a vent. The vent is selectively moveable between a closed configuration and an opened configuration to enable the user to access the exterior of the sleeping bag from within the sleeping bag. The vent comprises 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 configuration. The outer panel is spaced from the inner panel in the opened configuration to define a passage to enable the user to extend his or her feet through the vent.

Abstract: A luggage and luggage cart assembly includes a piece of luggage selectively moveable between a collapsed configuration and an expanded configuration. The luggage has a greater longitudinal length in the expanded configuration as compared to the collapsed configuration. A cart is selectively moveable between a retracted position and an extended position. The cart, in the retracted position, is sized and arranged to carry the luggage in the collapsed configuration and, in the extended position, is sized and arranged to carry the luggage in the expanded configuration. The luggage is selectively attachable and detectable from the cart. With the luggage in the collapsed configuration and the cart in the retracted position, the luggage and cart collectively have a maximum size less than or equal to 45 linear inches so that the assembly can be carried onto an aircraft.
