Certified bear-resistant by the IGBC (Interagency Grizzly Bear Committee), these coolers are made so tough even a Grizzly can't open them. And their features are plenty. To start, they hold ice up to 10 days (large models), thanks to freezer-grade gaskets and 2" polyurethane insulation (except 20 qt). Press and pull latches are extra wide for gloved use, while all hardware is stainless steel to resist corrosion. They also come with molded-in tie downs, molded-in lock hasps, and molded-in handles (except 20 qt) for extra durability. And depending on the model, they include either trolley or flip-style handles. Non-skid, non-marking feet are standard, too, as are sloped drains and tethered, threaded plugs; built-in bottle openers; and lifetime guarantees.
