These are actually a mug made by Bubba. But really, Yeti, Rtic, or anything else will do. Without something of your own, if you go to the bar and order a drink, you will get an eight ounce plastic cup that is open and will not keep your drink cold. With something like this, you can take whatever size you want, and close it to keep sand in pool water out of it and it will keep your drink cold. Old enough to know better, too young to care
