Description

The SM3 Radium helmet is engineered for MX, enduro and off-road use, featuring innovations and technologies optimized for ease of use, comfort and impact performance.

Shell construction uses a thermo-injected design incorporating a special polymer blend with varying thicknesses to deliver an optimal combination of impact protection and light weight.

An innovative low-friction coating is applied to the inner face of the main EPS liner to reduce rotational acceleration forces that can result from certain oblique impacts.

This slip layer mimics the brain's natural cerebrospinal fluid, acting as a low-friction plane to help manage oblique impact energy.

A patented visor release system ensures the visor releases at the correct pre-determined force, effectively reducing forces transmitted to the neck during an impact.

Ventilation is maximized with 10 inlets and 7 exhaust ports for high levels of heat transfer and airflow management.

Materials and composition include a mix of polymers and protective foams engineered for performance and durability.
