Oxo: Adventure Water Bottle-

This 12-oz water bottle features our patented, spill-proof straw that minimizes messy leaks, drips and dribbles. The valve opens the moment your tot’s lips touch the straw, so it's easy for kids who want to do it all themselves. The straw lid opens easily for toddlers, while grown-ups will have no trouble separating the two-part hinged cap for a thorough cleaning. The hourglass shape fits just right in little hands. The flexible handle hooks quickly onto diaper bags, backpacks and more to be within reach on every adventure.
