Expertly designed for MX and off-road performance, the S-M3 Heat Helmet is Alpinestars' advanced solution for riders seeking lightweight protection and superior heat management. Featuring a thermo-injected shell and a patented low-friction liner, it is rigorously tested to ECE 22.06 standards to minimize rotational impact forces. This ventilated helmet includes integrated hydration tube channels and an emergency release system for enhanced rider safety and convenience.

Key features

Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and engineered thickness to provide the optimal balance of lightweight performance and impact protection (Medium weighs 1430g ECE / 1460g DOT).
Maximized Ventilation: Equipped with 10 inlets and seven exhaust ports to ensure high levels of heat transfer and airflow during intense off-road riding.
Rotational Acceleration Protection: Incorporates a patented low-friction coating on the inner EPS liner that acts as a slip plane to reduce rotational forces during oblique impacts.
Patented Visor Release: Designed to release the visor with a precise, pre-determined amount of force to significantly reduce neck loading during an impact.
