Closed-cell foam is considered a better insulator than open-cell foam because the tiny bubbles of gas in closed-cell foam remain independent from one another. Air bubbles that do not share cell walls and in effect stay insulated from one another are better at reducing the overall transfer of heat through the foam. Closed-cell foam is also much more expensive to produce than open-cell foam. The resulting product is strong and especially rigid feeling, and typically it weighs more than 1.7 pounds per cubic foot with more than 90% of its air cells closed to one another. Closed-cell foam is also water-impermeable—so it’s an ideal material for, say, surfers’ wetsuits.
We tend to steer clear of most bargain-basement coolers—they may work well for a day or two but often lack the impressive ice retention of premium models and won’t stand up as well to regular outdoor use. Igloo’s Ecocool 52 isn’t totally exempt from these drawbacks, but it’s more well rounded and functional than much of the budget competition. For just $60, the Igloo boasts a generous 52-quart capacity, and the proprietary foam insulation does a good job keeping food and drinks coleman instant tent chilled for up to three days (in the right conditions, of course). The feature set is also pretty well sorted for the price, including four self-draining cup holders and functional lifts at the bottom that slightly elevate the cooler off the ground or truck bed. Igloo also added holes in the swing-up handles, allowing you to string a bungee between them to make carrying heavier loads easier. We’ve tested soft coolers for many years, and the Engel HD30 continues to impress us.
This particular market includes a huge range of prices that make one wonder if a plastic ice box could be worth that much money. In some cases, that extra cash does bring excellent insulation performance, greater utility, and convenience. In other cases, you can spend far less without a substantial drop in overall performance. It’s also helpful to consider how often you find yourself needing the cooling and insulating services these ice chests provide and how burly and rugged you need your gear to be. The most crucial aspect of any wheeled model is how easily it gets you there, which the RovR does spectacularly. That said, it lags a little in the insulation department compared to some intense rivals, which is likely due to the imperfect seal between the top of the body and lid.
Downsides are even more weight (the RovR and Igloo weigh around 35 lb.), bulk, and cost. Additionally, these wheeled beasts still struggle over rough terrain and may require carrying if you don’t have a defined path to follow. But for camping, days at the beach, or even tailgating, a rolling cooler can be a solid choice. It’s the only model we tested that has actual pneumatic tires instead of cylindrical plastic chunks labeled as wheels.
However, blocks are bulky and take up a lot of space in the cooler since they don’t conform around your food and cans. If we have enough space, our preferred method is to use both block and crushed ice together, and Yeti has more great tips here. The drain plug isn’t the only factor that makes emptying water easy or annoying.
The Interagency Grizzly Bear Committee keeps a running list of certified options, which includes a number of coolers from this rundown. Several models I’ve tested from Cabela’s, Orca, Rovr, Magellan Outdoors and Yeti all make the cut. If we’re going to talk about performance, we should talk about capacity first.
