The Definitely Water double-insulated tumblers are the perfect vessel for taking your favorite drink into the baseball game. Definitely water, of course. 


  • Clever design: One size labels the contents as "definitely water" while the other says "MPTHREE Baseball," so you know it's trustworthy. You're welcome. 

  • Superior Insulation: These 30-ounce tumblers are double-insulated to keep your beverages at the perfect temperature for hours. Whether it's hot coffee on a cold morning or icy cold water on a scorching day, our tumblers maintain the ideal temperature, ensuring you enjoy your drinks just the way you like them.

  • No More Sweating: These double-insulated tumblers are designed to be completely sweat-free, so the only thing that might sweat is you as your baby competes for his third "World Series" in 3 weeks.

  • Built to Last: Crafted with durability in mind, my heavy-duty tumblers are constructed to withstand the rigors of daily use. Put these up against batting gloves and see which one actually holds up. 

  • Versatility and Capacity: Hydration is key, right? At 30 oz, this size is ideal for staying hydrated throughout the day, reducing the need for frequent refills.

  • Stylish and Functional Design: These tumblers are not only practical but also aesthetically pleasing. Their sleek and timeless design complements any setting, making them perfect for both casual and formal occasions. Plus, they fit most cup holders, so they're perfect for on-the-go lifestyles, ensuring your drinks stay securely in place during your travels.
