Ursus arctos horribilis — the grizzly bear. Up to 1,500 pounds of muscle, teeth, claws and anger, they’re one of North America’s largest predators. But a YETI Tundra cooler can take one.

How does a YETI Tundra cooler stand up to massive, ill-tempered carnivores? Yeti ice chests feature a one-piece design made from highly durable roto-molded polyethylene. The lid is one piece, too, attached with molded-in, full-length hinges. Thanks to 2 inches of pressure-injected polyurethane insulation, even the most stubborn of grizzlies is going to give up and walk away in a huff long before your ice melts. Next time you head into bear country, camp with confidence by bringing along the bear’s natural enemy — a YETI Cooler.

Every product made by YETI Coolers is warranted against defects in material and workmanship for 5 years. This warranty applies only to the original owner. This warranty is void if the cooler is used commercially, structurally altered or subjected to stress beyond the physical limits of the materials used in body or components, or is damaged as a result of abnormal use. Normal wear and tear is not warrantied.

This warranty does not include any manufacturer responsibility for any incidental or consequential damages resulting from the use of the cooler. If warranty applies, the manufacturer will repair or replace, at their discretion, the cooler or any part or component that is deemed defective.

YETI Coolers reserves the right to change products and designs without incurring any obligations to incorporate such changes into already completed products, or those in the hands of dealers or consumers. Coolers repaired or replaced under this warranty may or may not incorporate these changes.

Damaged products must be returned directly to YETI Coolers, in the original box or adequate cardboard packaging, freight prepaid. Please include a copy of the original sales receipt and the Return Authorization Number (RMA#) with the product.

YETI Coolers are very strong and tough, but durability is just one of the benefits of a YETI. Outstanding thermal properties set YETI apart.

YETI Coolers are among the best insulated coolers on the market today (a full 2” or more of polyurethane insulation in the walls and lid of most sizes). This insulation, combined with a freezer-quality sealing gasket and durable one-piece construction gives YETI industry-leading ice retention. Use the information below to maximize your YETI Cooler’s performance.

• Due to the insulation in the product, the cooler will retain heat as well as coolness. For this reason, to maximize ice retention, try to store your cooler in a cool environment before loading it with ice. If stored in direct sunlight or in a warm environment, a significant amount of ice will be melted to cool the walls of the cooler. In extreme cases, clients have placed the coolers in a commercial freezer to pre-chill their coolers.
• Ice temperature is paramount; the temperature of ice could either be hovering at 32 degrees or sub-zero before you put it in your cooler. Therefore, ice that is colder will last much longer under identical conditions.
• Chilling or even freezing the intended contents, such as drinks and food is an often overlooked solution to longer ice retention. Remember, the colder your contents are before loading, the less energy these contents will use to cool.
• The amount of ice is important. We recommend filling the cooler with as much ice as possible to keep the air space to a minimum. Large areas of air will cause ice to melt faster. A small bag of ice in a large cooler will melt faster than if the same amount of ice were in a small cooler; however, a large cooler filled with ice will keep ice longer than a small cooler filled with ice. In summary, the more ice the better; however, if weight is a concern, you can use other materials, such as towels or crumpled newspaper to fill the air space voids.
• Surface area to volume of the ice also affects how ice melts. Block ice will melt much slower than small cubes or ice shavings. However, as ice melts, it absorbs the heat from its surroundings; therefore, smaller pieces of ice will chill the cooler faster. Also, it is easier to keep food cold using smaller pieces of ice. Using a mixture, for example, putting food on top of block ice, then covering the food and filling empty spaces with cube ice will help retain ice, chill, and keep food cold.
• Once the cooler is in use, we recommend that you do not empty the cold water. The water in the cooler will be almost as cold as the ice and will help insulate the remaining ice.
• Use dry ice to keep ice longer. For more information visit: Using Dry Ice.
• There are many variables that affect ice retention, such as frequent lid opening, outside environment, placement in direct sunlight, etc. Careful attention to these simple details will significantly extend ice retention.
