Expertly designed for MX and Enduro riding, the S-M3 Heat Helmet is an all-new off-road head protector engineered to deliver the optimal balance of impact protection and lightweight performance. Featuring an advanced thermo-injected shell and a patented low-friction internal coating, it effectively reduces rotational acceleration forces during oblique impacts. This ECE 22.06 certified helmet includes a multi-density EPS liner, integrated hydration tube channels, and an emergency release system for maximum rider safety and comfort.
Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and varying thicknesses, engineered for an optimal balance of impact protection and a lightweight feel (1430g ECE / 1460g DOT).
Maximized Ventilation: High levels of heat transfer and cooling airflow provided by 10 intake inlets and seven exhaust ports.
Rotational Acceleration Force 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 protection.
Patented Visor Release: Ensures the visor detaches with a pre-determined force during an impact to effectively reduce stress and potential injury to the rider's neck.
Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
Multi-density 5-piece EPS inner liner optimized for superior impact management and volume control.
Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
Eco-friendly comfort liner manufactured from recycled materials to reduce environmental footprint.
Customizable fit via interchangeable crown and cheek pads available in multiple thicknesses.
Optimized chin area shell thickness and structure for superior impact performance, tested to Alpinestars' rigorous in-house standards.
Engineering of inner and outer surfaces specifically designed to minimize the effects of oblique impacts.
Emergency Release System with removable 3D contoured foam cheek pads for safe and easy helmet removal.
25mm soft textile chin strap for secure and comfortable fastening.
Stainless steel D-rings for a reliable and tight fit.
Certified to ECE 22.06 homologation and DOT standards for global use.
