Expertly designed for MX and Enduro riding, the S-M3 Radium Helmet features an advanced thermo-injected shell with varying thicknesses to optimize impact protection and weight. Rigorously tested to exceed ECE 22.06 standards, it utilizes a multi-density EPS liner and a patented visor release system to significantly reduce rotational acceleration forces. This ventilated helmet includes a moisture-wicking comfort liner and integrated hydration tube channels for superior performance in off-road conditions.
  • Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and varying thicknesses to provide the optimal balance of lightweight performance and impact protection.
  • Optimized Weight: Engineered for agility and comfort, the S-M3 medium weighs 1430g (ECE) and 1460g (DOT).
  • Maximized Ventilation: High levels of heat transfer and cooling airflow are achieved through 10 strategic inlets and seven exhaust ports.
  • Rotational Acceleration Protection: Patented low-friction coating on the inner EPS liner reduces rotational forces during oblique impacts by mimicking the brain's natural cerebrospinal fluid defense.
  • Patented Visor Release: Ensures the visor detaches with a pre-determined force during an impact to effectively reduce strain on the rider's neck.
  • Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
  • Multi-density EPS liner featuring 5 individual parts with 4 distinct densities for optimized impact management.
  • Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
  • Eco-friendly comfort liner constructed from recycled materials to reduce environmental impact.
  • Customizable fit via interchangeable crown and cheek pads available in various thicknesses for a tailored head shape.
  • Optimized chin area shell thickness and structure for superior impact performance, exceeding standard homologation requirements.
  • Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
  • Emergency Release System (ERS) with removable 3D contoured foam cheek pads for safe helmet removal.
  • 25mm soft textile chin strap for secure and comfortable fastening.
  • Stainless steel D-rings to ensure a consistent and tight fit.
  • Certified to ECE 22.06 and DOT standards for global use.
