Long workouts, hard days of work, vacations—this tumbler is a perfect addition. Double-wall vacuum insulation will keep your drinks cold for hours. The lid features a rotating cover with three positions: an opening for the reusable straw, an opening for sipping, and a full-cover top to prevent splashes. All tumblers come with your design laser engraved right here in the USA. Complete with a comfortable, ergonomic handle for carrying.
