Description
The Alpinestars SM3 Radium Helmet delivers a blend of performance, protection, and comfort for MX, Enduro, and Offroad riders. Featuring a thermo-injected shell with varied thickness for optimal impact protection and lightweight feel, this helmet uses a composite fiber inner shell for maximum safety. Multiple density EPS liner ensures enhanced impact absorption, while the low friction coating aids in rotational impact management. With ten intake and seven exhaust ports, ventilation is maximized for superior heat transfer. The visor is designed for optimal airflow and features a release system for added neck protection in impacts. The comfort liner uses recycled materials and integrated hydration tube channels for added convenience. Safety is enhanced with an emergency release system and stainless steel D-rings for a secure fit. Conforms to DOT and ECE 22.06 standards.
