Owala® FreeSip 24-ounce water bottle

which is why we're big fans of their water bottles. The 24-ounce FreeSip design gives kids two ways to drink: sip through the built-in straw or tilt back to swig through the wide-mouth opening. A push-button lid makes it easy to open (while keeping germs out) and yes, it's completely leakproof. The bottom line: no spills in backpacks, lunch boxes or gym bags—just all-day hydration for your little.
