Trusted by marine enthusiasts since 1967, our Marine cooler collection is built with the essential features for life on/near the water. You can depend on this extra-large and super-spacious Marine Ultra ice chest (it fits 149 cans!) — as an avid fisher, an occasional boater or someone who frequents the outdoors with family and friends — to keep your catch or your provisions chilled. We included thoughtful details to make life easier, like UV protection, grippy handles (even in wet conditions), rust-resistant hardware, drain plug, etc.
