Your Spider-man rider is sure to love this Spider-Man child bike helmet featuring your favorite web slinging hero. The PinchGuard™ buckle and nine vents help keep heads ventilated while your little one cruises the neighborhood, park or trails. Most helmets have multiple points of adjustment to get the correct fit, but this helmet is our easiest fitting helmet ever. With a simple one-step adjustment system called True Fit™, you simply tighten or loosen the chin buckle and are ready to ride.
