Yeti can do 5 days—if you don't open it like a fridge

Yes, a Yeti can keep ice for five days in 90-degree heat, but only under fairly specific conditions. It’s not pure marketing, but it’s also not magic.

The key is ratio. A big Yeti Tundra packed with ice and cold drinks will hold ice for days. A small Roadie with a few warm beers and a handful of cubes won’t. Think of the cooler as a thermos: the more thermal mass you put in cold, the longer it stays cold. Block ice is better than cubes. Pre-chill the cooler the night before. Drain water instead of letting your drinks swim—water conducts heat away from the ice.

And stop opening it. Every open lid trades cold air
