Coleman Classic Series 52-Quart Marine Hard Cooler

For camping: Definitely lasts multiple days for 2-3 persons if you follow a few simple tips: Freeze gel packs (not ice) at your freezer's lowest setting, Freeze or refrigerate all food and drinks, Pre-cool the cooler for hours before loading, Load just before you leave, Keep the cooler covered or out of the sun. That's it -- lasted 5 days for us and everything was cold. Excellent quality cooler.

We do a mid major city farmers market. We take 20 to 28 coolers every Saturday, 52 weeks a year, with rather expensive frozen meat products. All of our coolers are Coleman marine coolers. and in the last year, we started making the switch to the 52 quart 316 series cooler. They have proven to be extremely rugged, reasonably priced, and most important of all, keep our frozen meats frozen till we get home 10 hours later, even on the hottest of summer days. These coolers have proven themselves to stand up to constant use and rigors of our business. Thanks Coleman.
