YETI Tundra 35: best cooler for keeping food hot
The same 3-inch pressure-injected polyurethane insulation that produces YETI's class-leading cold retention equally resists heat loss. In our test with pre-heated cooler and food packed at 165F, the YETI Tundra 35 maintained above 140F temperatures for 6.5 hours -- well within food safety requirements for a typical tailgate or outdoor event.

Common questions
Yes. The same insulation that keeps cold contents cold keeps hot contents hot. A rotomolded cooler like the YETI Tundra pre-heated with boiling water maintains food above 140F for 6 or more hours.
Hot food must be kept above 140F to remain in the food-safe temperature zone. Below 140F, bacterial growth accelerates. Above 140F, bacteria cannot survive and multiply.
Pour boiling water into the empty cooler, close the lid, and let it sit for 15 to 20 minutes. Drain the water and immediately pack your pre-heated food. The pre-heated cooler walls dramatically reduce heat loss from food to the cooler.
A pre-heated YETI Tundra or RTIC with hot food in sealed containers maintains above-140F temperatures for 4 to 6 hours. Wrap containers in aluminum foil before placing in the cooler for additional insulation.
