Get ready to roll with the Cartwheel, the coolest companion for your kiddo's adventures! We took the oops! out of the equation with its spill-proof straw. Designed to fit by their side, the cartwheel is cupholder-friendly, and totally tantrum-proof (thanks, impact resistant Tritan!). This BPA-free, dual-wall insulated tumbler holds 12oz of their favorite drink, keeping them colder longer. As always, this Reduce bottle is dishwasher friendly.
