ALPINESTARS(MX) SM3 Heat Helmet — Size 2XL, Silver
Off-road helmet engineered for MX and enduro with optimized ventilation and impact performance.
The SM3 Heat helmet is engineered for MX, Enduro and off-road use, combining ease of use, comfort and impact performance.
Shell construction uses a thermo-injected shell with a special polymer blend and variable thickness to deliver an optimal combination of impact protection and light weight.
A patented low-friction coating on the inner part of the main EPS liner reduces rotational acceleration forces from oblique impacts by acting as a slip plane similar to cerebrospinal fluid.
The patented visor release system ensures visor separation at a predetermined force, effectively reducing forces on the neck during an impact.
Ventilation is maximized with 10 inlets and 7 exhaust ports for high levels of heat transfer and airflow.
