SM3 Solid Helmet is engineered for MX, enduro and off-road use, featuring innovations optimized for ease of use, comfort and impact performance. 🛡️
The shell uses a thermo-injected construction with a special polymer blend and variable thickness to balance impact protection and low weight.
A patented, low-friction coating is applied to the inner surface of the main EPS liner to reduce rotational acceleration from oblique impacts; this slip plane mimics the brain's cerebrospinal fluid. ⚙️
A patented visor release system ensures the visor detaches with a predetermined force to reduce neck loads during an impact. Maximized ventilation and high heat transfer are provided by 10 inlets and 7 exhaust ports. 🌬️
