The new SM3 youth helmet has been specially developed for teenagers and younger riders. It is optimized for MX, enduro and off-road use and features numerous technologies and innovations from the helmets for adults to offer the optimum mix of performance, protection and comfort.
Features:
Lightweight construction: Thermally injected shell made from a special polymer blend with different thicknesses for an optimum combination of impact protection and low weight
Material: Outer shell made of impact-resistant thermoplastic, available in three sizes (Youth Small, Youth Medium and Youth Large)
Customizable fit: helmet calotte and cheek pads in various thicknesses available as spare parts. Sizes Youth Medium (YM) and Youth Large (YL) have the same EPS size for growth with the rider. Youth Small (YS) has a smaller EPS size and special fit for 3-4 year old children
Multi-density: Inner lining with different densities for better impact protection and reduced overall weight
Angled impact protection: Inner and outer surfaces minimize impact from angled shocks. Patented low-friction coating reduces rotational acceleration forces

Visor: Designed to improve airflow. Patented visor release system reduces forces in the event of an impact
