A winner in our 2010 report, the Coleman 50-Quart Wheeled Ultimate Xtreme gets top honors again. writer Tom Bartlett gives this cooler high ratings for its ability to sit under a hot sun for four days and still keep food and drinks cold; he adds that while this doesn't quite meet the manufacturer's claim of six days, it could probably do so if kept in the shade and properly packed. Bartlett and other reviewers also like the cooler's roomy capacity, and ease of loading and hauling. Amenities such as large, smooth-rolling wheels; easy-open lid; sturdy handle; and cup holders are nice details.

User reviews on retail sites such as,, and praise the cooler's rugged, hard-shell exterior, which protects food and drinks from getting smashed; its 72-can capacity; and its channel drain that allows you to empty ice melt without having to tip the cooler over. It's important to note that several sites, such as and, have reviews for various sizes of the Coleman "Xtreme" but not the Ultimate Xtreme; this new and improved model promises to keep food and drinks cold for six days instead of five.

This Australian consumer website conducts tests on a variety of medium-sized coolers by first chilling them to 71 degrees F, then loading them to 35 percent capacity, filling them with ice and placing them in a 90-degree F room. Tester James Thomson then checks each cooler to see how long it takes for the cans inside to warm up a few degrees; he also tests the coolers for lid latch security, and ease of loading and hauling.

There's only one review available for the 50-quart Wheeled Ultimate Xtreme model (although other sizes of Ultimate Xtreme coolers also get enthusiastic posts); however, this owner gives the review some weight by saying the cooler can hold ice throughout a five-day trip in the desert.
