With a completely redesigned exterior and adjusted features, the Smiley 3.0 Ace Led enters a new era. The deep fit and visor provide additional protection for the child's head. The height-adjustable adjustment system allows for easy adaptation of the helmet to the head circumference—both in width and height at the back of the head. Another advantage of the height-adjustable adjustment system is that it creates space for a ponytail for children with long hair, eliminating the annoying pressure of the adjustment wheel on the ponytail. Comfort is further enhanced by a thick chin pad. In the Ace Led version, the popular children's helmet features a rear light. The light can be easily charged via a USB connection. The rear light increases visibility in low-light conditions. Additionally, the helmet is equipped with an extra outer shell at the lower edge, which better protects the helmet from wear and tear and provides an optical highlight.
