This practical buy may become your favorite year-round drinking cup. It keeps drinks hot for 45 minutes, chilled for up to four hours and iced for up to 15 hours. From frosty lemonade in the summertime to hot lattes in the winter, this will be the cup you grab for basically everything. Best of all, if you buy more than one, they stack for easy storage. More than a dozen colors are on sale, and they're already starting to sell out.
"Love, love, love these cups!" a fan wrote. "[They] keep things cold and hot things hot. Dishwasher is a definite plus! [I] bought seven — one for myself, [and] the rest for Christmas gifts."
