A backpack is provided with a mechanism whereby it can be used in a compact form for carriage of smaller loads or in an expanded form to carry larger loads. In its initial compact form, the backpack's cargo space is divided into two separate compartments which are fixedly attached along their outer vertical seams to the outer edges of the backpack's main panel, and are releasably attached to each other along a central vertical seam by means of a zipper or similar such fastening system. When this said fastening system is released, the primary storage compartments hinge and rotate outwardly, exposing a space that is made available for additional storage. A collapsible supplemental storage compartment is sewn or otherwise attached into this space in such a way that it can be opened and expanded when the afore-mentioned primary storage containers are outwardly deployed. The backpack is fitted with two shoulder carrying straps, and in a preferred embodiment would be fitted with a waist belt.
