ALPINESTARS(MX) SM3 Heat Helmet — XL, Pink/Purple/White

The SM3 Heat Helmet is engineered for MX, enduro and off-road use, delivering a balance of comfort, usability and impact performance. 🔥

Its thermo-injected shell uses a specially formulated polymer blend with variable thicknesses to optimize protection while keeping weight low.

A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration in certain oblique impacts, acting as a slip plane to mimic the brain's natural cerebrospinal fluid defense. ✅

The helmet features a visor release system designed to release at a controlled force, helping to reduce neck loads during an impact.

Ventilation is maximized with ten inlet ports and seven exhaust outlets to improve heat transfer and airflow for extended off-road sessions. 🌬️
