Hydro Flask. 40 oz. Vacuum Insulated. Stainless steel. We have 4 of them and they work perfectly. Too large for a conventional up holder in a car.
I started with KleenKCanteen but upgraded to Hydro Flask. Hydro Flask is super insulated and they work great. They are pricey, though. I must have gotten them on sale because I have two of the 24oz bottles. If I wanted bigger, I'd look at the 40oz RTIC bottle for a better price. But the hydrofask is dishwasher safe while the RTIC is not.
