Engineered for MX, enduro and off-road with a lightweight thermo-injected shell and advanced impact protection.
The SM3 Heat Helmet is engineered for motocross (MX), enduro and off-road use, featuring innovations optimized for ease of use, comfort and impact performance. 🚵♂️
Its thermo-injected shell incorporates a special polymer blend with varying thickness to deliver an optimal combination of impact protection and light weight.
An Alpinestars-patented low-friction coating is applied to the inner expanded polystyrene liner to reduce rotational acceleration from oblique impacts, mimicking the brain's cerebrospinal fluid. 🧠
The visor features a patented release system that ensures correct pre-determined release force to reduce neck loads during an impact.
Ventilation is maximized with 10 inlets and 7 exhaust ports for efficient heat transfer and airflow.
Shell composition includes acrylonitrile-butadiene-styren, polyurethane, expanded polystyrene and other engineered materials for controlled energy management.
