The best camping drinkin cup I've ever had.....

We have two Walmart Ozark 20oz and a RTIC 20oz. They keep stuff cold pretty much the same even the lids are interchangeable. Love them. First think I had to learn was don't over fill them with ice unless you're going to be away from the ice supply all day. WIth less ice there is more room for beverage. I usually get by putting 4 or 5 cubes in twice a day and just keep refilling with more beverage as needed.
