A foldable carrier is provided with a vertical support panel structure made as a first component, and an external side wall structure as a second component. The vertical support panel structure and the external side wall structure are joined together to form two separate receptacles extending from opposite sides of said vertical panel structure to hold objects to be carried in the carrier. Preferably, the vertical support panel structure is made of an untreated and relatively inexpensive material, and the external side wall structure is made of a material treated to give it good resistance to weakening when wet.
