Halfway between a grownup bottle and a sippy cup, our bestselling kids bottle gets an upgrade with an insulated design. The colorful, double-walled bottle won't collect condensation, which keeps the bottle from sweating and makes it easier for kids to grip. We've also tweaked the design of our grownup eddy bottle to make this version child-safe and free of choking hazards - the colorful bite valve is easy for adults to remove, but it won't pop off in little hands.
