The deep fit and peak offer additional protection for the child's head. The height-adjustable adjustment system allows the helmet to be easily adjusted to the head circumference - both in width and height at the back of the head. Another advantage of the height-adjustable adjustment system is for children with long hair, as it creates space for a plait. This puts an end to the annoying pressure of the adjustment wheel on the plait. Wearing comfort is also increased by a thick chin pad. The Ace Led version of the popular children's helmet has a rear light. The light can be easily charged via a USB port. The rear light increases visibility in poor light conditions. The helmet is also equipped with an additional outer shell on the lower edge, which protects the helmet better from signs of wear and provides a visual highlight.
