A dry-compartment cooler has a dry compartment (1) with compartment walls (3) that are connected water-tightly to a compartment floor (4). The compartment walls are articulated to extend upwardly from proximate a riser framework (6) on a cooler floor (7) to proximate a bottom side of a cooler lid (8

A dry-compartment cooler has a dry compartment (1) with compartment walls (3) that are connected water-tightly to a compartment floor (4). The compartment walls are articulated to extend upwardly from proximate a riser framework (6) on a cooler floor (7) to proximate a bottom side of a cooler lid (8) of a predetermined cooler. One or more ice compartments (10, 11, 12, 13, 14) separate ice and water from inside surfaces of the compartment walls and from space inside of the dry compartment. The ice compartments are in fluid communication intermediate proximate the bottom side of the cooler lid and riser-framework space (9) where the riser framework is positioned under the compartment floor. The compartment walls can have heat-conveyance members (27) for conveying coldness and for deterring moisture formation on food and other items being cooled.
