Description

Expertly designed for off-road performance, the S-M3 Jettson Helmet features an advanced thermo-injected shell engineered for the optimal balance of impact protection and lightweight agility. This ECE 22.06 certified helmet incorporates a patented visor release system and a low-friction internal coating to significantly reduce rotational acceleration forces during impacts. Riders benefit from maximized ventilation through 17 ports, integrated hydration tube channels, and a customizable fit for superior comfort on the track or trail.

Key Features
  • Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend of varying thicknesses, engineered to provide the optimal balance of lightweight performance and impact protection.
  • Lightweight Performance: The S-M3 weighs 1430g (ECE) and 1460g (DOT) in size medium, reducing rider fatigue during off-road use.
  • Maximized Ventilation: Equipped with 10 inlets and seven exhaust ports to ensure high levels of heat transfer exchange and rider comfort in intense conditions.
  • Rotational Acceleration Force Protection: Utilizes a patented low-friction coating on the inner EPS liner to act as a slip plane, mimicking the brain's natural defenses to reduce rotational forces from oblique impacts.
  • Patented Visor Release: Designed to release with a pre-determined amount of force during an impact, effectively reducing potential neck forces for enhanced safety.
Protection
  • ECE 22.06 and DOT certified for global use.
  • Optimized chin area shell structure exceeds standard homologation impact requirements.
  • Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
  • Emergency Release System (ERS) allows for safe and easy cheek pad removal while the helmet is worn.
  • High-density 3D contoured foam ensures a secure fit and rider protection.
  • 25mm soft textile chin strap provides optimal safety and comfort.
  • Stainless steel D-rings ensure a reliable and tight closure.
