Abstract
Abstract A multi-compartment, expansible luggage bag has a main storage compartment with one or more expansible joints to increase the size of the main storage compartment. In conjunction with the main storage compartment, there is also provided a separable end storage compartment having an inner flexible membrane that can be extended inwardly beyond each of the expansion joints to maximize the volume of the end storage compartment when the expansion joints are open.
