The S-M3 Radium Helmet is engineered for MX, Enduro and off-road use, combining ease of use, comfort and proven impact performance.

  • Thermo-injected shell constructed from a special polymer blend with varying thicknesses to deliver an optimal balance of impact protection and light weight.
  • An innovative low-friction coating applied to the inner EPS liner reduces rotational acceleration from oblique impacts by providing a slip plane that mimics cerebrospinal fluid.
  • Patented visor release system releases at a predetermined force to help reduce neck loads during an impact.
  • Maximized ventilation with 10 inlets and 7 exhaust ports for efficient heat transfer and sustained airflow.

Purpose-built for riders who demand protection and comfort on technical terrain. ✨🏁
