Safe, light as a feather and well ventilated: this is what a riding helmet for children and young people should be like. Whether it’s the first jumps in the countryside or a walk through the countryside: the uvex onyxx masters all terrains. With the 3D IAS system, the height and width of the helmet can be perfectly adapted to the shape of the head and continuously grows from 49 cm to 54 cm head circumference. Thanks to the Quick Adaptation System and the Monomatic closure that can be operated with one hand, the inmould helmet sits firmly on the head in any situation. This not only increases the comfort of use, but also ensures optimal protection in an emergency.
