Roaaarrr!! Your little dinosaur is sure to love the intelligently designed Raskullz Lil Dino infant helmet. The purposeful flat back design allows for your little rider to sit confortably in a child carrier or trailer. The exposed foam on the rear of the helmet helps dampen bumps against thier seat. The bike helmet features awesome dino graphics and a lime green bendable 3D mohawk. Recommended for kids 1 to 3 years old with heads measuring 48-52cm.
