Just like the Tundra® Cooler, the Hopper® Cooler is designed to keep ice colder longer, but there are many variables that can affect your ice. This includes the temperature of the cooler when being loaded, ice quality, ice quantity, type of ice (crushed, block, cube), outside environment, exposure to direct sunlight, etc. We suggest cooling your cooler down by “sacrificing” a bag of ice in your cooler before putting in a second bag with your refreshments.
