Alpinestars S-M3 Fray Helmet ECE 22.06

Key features

• Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend of varying thicknesses, engineered to provide an optimal balance of impact protection and lightweight performance (1430g ECE / 1460g DOT).
• Maximized Ventilation: High levels of heat transfer and cooling airflow are achieved through 10 intake vents 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: Designed to release the visor with a precise, pre-determined force to reduce stress and potential injury to the rider's neck during an impact.
