These bold, colorful tumblers are made to keep you hydrated in a fully functional style. Ideal for car commutes or workouts at home. Snap it shut and the double-wall vacuum insulation will keep your drink fully leakproof and extra cold for hours. It fits comfortably in your vehicle’s cup holder (treadmills and spin cycles, too!) and the folding handle lets you quickly grab and go. Kids will also love the rotating handle that makes portability a cinch, the ergonomic profile that complements smaller hands, and the car cup holder-compatible design.
