A mobile cooler having a flexible tank track for moving the cooler over sand or irregular ground surfaces. The track members of the flexible tank track are normally made of rubber and are recessed into the outermost surfaces of the side walls of the insulated container to improve appearance of the cooler and to provide minimum obstruction to other articles when the cooler is stored in trunks or other compartments of automobiles. A retractable cord, attached to a spring loaded pulley recessed into the lower front wall of the cooler, facilitates towing of the cooler from place to place in a picnic area. A vertical levelling slot in each of the front axle supports keeps the track members in maximum contact with the surface of the ground during the towing process. Conventional pivotable handles attached to the front and back walls of the insulated container allow the cooler to be easily lifted or lowered in storing or retrieving the unit from storage.
