We believe that every child should wear a properly fitted helmet when scooting which is why we have created a range of eye catching designs. Our helmets come with a magnetic chin strap that won't pinch necks! In addition we have a great intergrated rear light, adjustable safety straps and air vents to keep your child's head cool. Small helmet size: 48cm - 52cm/ Medium helmet size: 53cm - 58cm. Please make sure you measure your child's head before ordering. Not suitable for children under 3.
