Just got my 110qt ark series cooler a couple months ago. Took it out to Sonora Mexico on a coues deer hunt last week. I loaded it up with ice on Thursday night, crossed the boarder on Friday morning. My friends that were hunting also did the same with their canyon cooler it was about the same size 100 qt iam guessing. We both put our coolers side by side in the shade all week, 9 days later when we were packing out our deer meat the canyon cooler had about 1/4 of the ice left and most of the bags were totally melted the blue cooler 110qt had around 80% of the ice left. I had to give bags of ice to my friends so they could pack the deer meat. We were all blown away by how well the cooler held the ice!! And they were all impressed by the wheels and handle so one guy could roll it around. Everyone was gonna by blue coolers after seeing how much better it was in a real world side by side comparison. Nothing better on the market today!! 👍
