Keeps kids active and safe with the Nickelodeon Teenage Mutant Ninja Turtles Raphael Child Bike Helmet. A cool design looks just like the popular cartoon character with a signature 3D mask. It\'s specially designed for cycling, but the open-face style also works well for skateboarding and more. A tough molded exterior protects against injury. The EPS inner shell absorbs shocks in the event of a tumble or collision. Aerodynamic cooling vents help kids stay comfortable, even with vigorous exercise.
