Helmet built for demanding terrain with advanced impact mitigation, low-friction slip-plane liner, patented visor release and enhanced ventilation.
The SM3 Fray Helmet is engineered for demanding terrain and varied riding conditions, featuring innovations optimized for ease of use, comfort and impact performance. 🏁
Shell construction uses a thermo-injected design with a special polymer blend and varying thicknesses to balance impact protection and low weight.
An innovative low-friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts, acting as a slip plane to mimic cerebrospinal fluid.
A patented visor release system ensures visor detachment at a predetermined force to reduce neck loads during an impact.
Maximized ventilation and efficient heat transfer are achieved through a network of inlets and exhaust ports for sustained airflow.
