Day 5/12: in the last few years Yeti coolers, bottles, and tumblers have been along for every road trip, and most of my adventures. I am in awe at their capabilities and ability to stay cold for extended periods of time.
The coolers are amazing. Nearly indestructible (as proven in this video), functional, and awesome. We have a couple of sizes of the coolers, and one of the Hoppers (soft coolers) as well. On our spring break last year, we had a cooler that held ice for 10 days of road tripping in the desert.
I use the water bottles and tumblers every day. They keep cold things cold, and hot things hot. Durable and functional, what else do you need?
