Some use cans as a unit of measure, while others use liters, quarts, or gallons. That said, “cans” is the most commonly used measurement for soft coolers (hard-sided models are generally listed in quarts), and we’ve utilized that spec throughout this article whenever available. That said, igloo soft cooler there are still some discrepancies to be aware of, the biggest of which is whether or not ice is included in that estimate. We did our best to clarify in the write-ups and comparison table above, but it’s an important distinction to keep in mind when shopping for a soft cooler.
The REI Trail Pack is one of our favorites for fully loaded distance missions, offering all the comfort of a backpacking backpack with its perfectly padded weight-bearing waistbelt. Though not completely waterproof, we still find ourselves reaching for its straightforward functionality and above-average insulation time and time again. The most inexpensive cooler we generally recommend is the Arctic Zone Titan. It’s surprisingly easy to use and handy for infrequent use at a bargain price. This rigid cooler doesn’t fold down, and its footprint is rather large. That said, with a full load of groceries, its bulky size can be awkward to carry.
We periodically checked, making notes regarding melt rate, condensation, and leaks. Each reported time is based on when 100% of the ice was converted to water. But when traveling outdoors, these controlled igloo water cooler variables disappear and the ice will likely melt faster. We took this cooler on a two-person, 3,400-mile road trip from Colorado to Washington for ski mountaineering followed by ocean surfing.
It’s hard to gauge how stiff or user-friendly a soft cooler might be from a product description since few manufacturers list the thickness of their cooler’s walls in their specifications. Many longer-lasting soft coolers weigh between 5 and 10 pounds, which gets heavier as you add heavy liquids and ice. Consider how long you need a cooler to retain cold and how far you might be carrying it on an average outing as you balance weight and performance concerns in your purchasing decision. While we tested during cooler fall temperatures, the Walker delivered days of ice retention versus the hours we got from flimsier bag-style soft coolers. Those times would be shortened in direct sun and high temps, but the thick walls of the Walker are more than enough for a day at the beach.
Most cooler manufacturers provide a “claimed ice retention” spec in their product listings (YETI is one major brand who does not). From our list above, times range from just 4 hours at the low end for the Hydro Flask 20 L Insulated Tote to three or four days at the high end for Engel’s HD30 (24 hours is pretty standard). That said, igloo water cooler we always take manufacturer-provided specs with a grain of salt, and there isn’t an established, standardized test here. If we had to generalize it, we would say that you should expect to get approximately half of the claimed ice retention time in real-world use, give or take a bit depending on your specific circumstances.
