Expertly engineered for off-road performance, the S-M3 Heat Helmet is Alpinestars' versatile solution for MX and Enduro riders seeking advanced impact protection. Featuring a thermo-injected shell with a multi-density EPS liner and a patented visor release system, it is rigorously tested to exceed ECE 22.06 standards. This lightweight helmet delivers superior ventilation and rotational force reduction for maximum rider comfort and safety.
Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and engineered thickness to provide the optimal balance of impact protection and lightweight performance (1430g ECE / 1460g DOT).
Maximized Ventilation: Optimized airflow and heat exchange through a system of 10 intake vents and seven exhaust ports for superior rider cooling.
Rotational Acceleration Protection: Patented low-friction coating on the inner EPS liner acts as a slip plane to reduce rotational forces during oblique impacts, mimicking the brain's natural defenses.
Patented Visor Release: Engineered to release the visor with a precise, pre-determined force to effectively minimize neck strain and impact forces during a crash.
Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
Advanced 5-piece EPS inner liner with 4 specific densities for optimized impact management and performance.
Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
