The Igloo Marine Ultra Quantum 28 Quart Roller Cooler utilizes UV inhibitors and infrared technology that protect the cooler against sun damage. This cooler features a locking, telescoping handle equipped with gear hangers to hold totes, bags, and more, plus, non-marking, soft ride rally wheels for easy transport and a smooth ride. Cool Riser Technology improves cooling performance by elevating the cooler body from hot surfaces. Four self-draining cup holders have been built into the lid to keep your drinks secure and handy. Integrated pouring channels in the liner allow for easy purging of melted ice. The lockable lid loops used for maximum security also allow extra gear to be tied to the cooler for easy transport.
