Yeti Tundra 50 Cooler

If you’ve got a big trunk and a big budget, the Yeti Tundra is your best bet. With models ranging from 35L (picnic size) to 350L (back of a yacht size), the Tundra line has something for every road tripper. After testing the 50L, we recommend something in the 35-65L range—depending on how much space you have and how often you’ll be able to resupply. If you’re traveling by yourself or are going to be taking shorter day trips, consider the Yeti Roadie, which is a 20L more portable option. Whichever size you pick, combine this heavy-duty, insulated behemoth with Yeti’s ice packs to avoid having melting ice ruin your perishables.
