For more than 50 years, Engel has been developing the very best Coolers in the business. As the Original High Performance Cooler Company, Engel was first to develop the High performance Roto-Molded Cooler. Not just an improvement on the old models, but a brand new concept, designed from the ground up to re-define what an ice chest could be. Rugged enough to stand up to a hungry Grizzly bear, with a full two-inches of dense polyurethane foam injected in the top, bottom and sides, to provide 8-10 days of cold-keeping capability. Patents are pending.
