Alpinestars SM3 Youth Radium Helmet

The new SM3 Youth helmet has been specially developed for teenagers and young riders. Optimized for MX, Enduro and Offroad use, it features numerous technologies and innovations from the adult helmets, offering the best combination of performance, protection and comfort.

Facial Features:

• Lightweight Construction: Heat-injected shell made from a special polymer blend with variable thicknesses for the optimal combination of impact protection and light weight
• Material: Impact-resistant thermoplastic outer shell, available in three sizes (youth small, youth medium, youth large)
• Customizable fit: Helmet carotids and cheek pads are available in different thicknesses as spare parts. Sizes Youth Medium (YM) and Youth Large (YL) have the same EPS size to grow with the rider. Youth Small (YS) has a smaller EPS size and fits specifically for kids aged 3-4 years old
• Multi-Density: Varying density inner lining for increased impact protection and reduced overall weight
• Angular Impact Protection: Inner and outer surfaces minimize impact from angular impacts. Patented low-friction coating reduces rotational acceleration forces
• Ventilation: 10 air intakes and 7 exhaust ports for maximum ventilation and heat transfer
• Visor: Designed to improve airflow. Patented visor release system reduces forces in the event of an impact
• Comfort Liner: Made from recycled materials to reduce carbon footprint. Integrated channels for drinking tubes in cheek pads
• Safety features: Soft textile chin strap (25mm wide), emergency release system and removable cheek pads for safe removal, stainless steel D-rings for a secure fit
