Launched in 2014, quantum, Igloo's new series of hard-sided coolers, features a distinctive, modern design created with user convenience in mind. With multiple built-in value features, Quantum exceeds traditional coolers with a bright look, bold graphics, honeycomb-textured inserts, integrated pouring channels in the liner, lockable lids, and self-draining cup holders. This Ice chest cooler with wheels is 52-quart.
