The flask has been around since… well, we’re not sure, but it’s been a damn long time. Point is, chugging booze out of a Smart Flask — now with a built-in heart rate monitor! — just sounds silly. The Great American Flask ($195) is anything but silly. It’s hand-soldered out of pure copper and lined using a traditional hot-tinning method. It’s made in Chattanooga, TN, and holds nine ounces of the stuff that cures what ails ya. Save the tech for the phones and watches–leave the flasks alone.
