Alpinestars Youth SM3 Radium Helmet

The all-new SM3 Youth Helmet, designed with precision for young and aspiring MX, Enduro, and Off-road enthusiasts, embodies a fusion of advanced technologies derived from the expansive Alpinestars adult helmet collection. This helmet ensures a superior blend of performance, protection, and comfort tailored specifically to the anatomy of youth riders.

• Thermo-injected shell
• 3 shell sizes
• SM3 Youth weighs 1060g (ECE) and 1170g (DOT)
• Fit can be tailored to the rider’s head replacement liner and cheekpads
• DOT certified version of the helmet’s inner shell is constructed with a composite fiber assembled between the outer shell and the EPS liner for maximum protection against impacts

Comfort:

• Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size
• The Youth Small (YS) has a smaller EPS size and can be customized only via the cheek pads
