Engineered for motocross, enduro and off‑road riding, the SM3 helmet combines advanced impact performance with rider-focused comfort and intuitive usability. 🪖
Its thermo-injected shell uses a special polymer blend with varying thicknesses to achieve an optimal balance of impact protection and reduced weight.
An innovative low-friction coating is applied to the inner face of the main EPS liner to limit rotational acceleration from oblique impacts.
This slip-plane layer is designed to mimic the brain’s natural cerebrospinal fluid, helping to reduce forces transmitted during certain angled impacts.
A patented visor release system ensures the visor releases at a predetermined force, helping to limit neck loads in the event of an impact.
Maximised ventilation and efficient heat exchange are delivered through 10 inlets and 7 exhaust ports for sustained comfort during high-exertion use. 💨
