Nuby knows little ones are animated and active, even while holding (or sometimes dropping) their drinks. Nuby's Flip-It Active Stainless Steel Water Bottle offers a leak-proof Flip-It top, so parents don't have to worry about spills and leaks! The press button flip top keeps the straw clean and locks when not in use. Little ones can simply flip the latch and press the button to release the straw and get drinking. This toddler water bottle also features a durable, stainless steel base with fun prints your child will love. The stainless steel bottle base is insulated, keeping liquids cool and furniture protected from condensation, making it a back to school must have. The Flip-It Active Stainless Steel Water Bottle is designed with a soft silicone straw that is gentle on your child's teeth and gums. Whether your child sits still while sipping or frequently knocks over and holds their cup at an angle, our Nuby Thirsty Kids water bottles have you covered.
