Alpinestars SM3 Solid Helmet — Size L, Black

The S-M3 Helmet is engineered for MX, enduro and off-road use, featuring innovations optimized for ease of use, comfort and impact performance. 🏁

Thermo-injected shell uses a special polymer blend with varying thickness to balance impact protection and low weight.

A patented low-friction coating is applied to the inner EPS liner to reduce rotational acceleration from oblique impacts, acting as a slip plane similar to the brain's cerebrospinal fluid. 🧠

Patented visor release system ensures the visor releases at a predetermined force to help reduce neck loads during an impact.

Maximized ventilation with 10 inlets and 7 exhaust ports provides high levels of heat transfer and airflow.

Composite construction includes acrylonitrile-butadiene-styrene, polyurethane, EPS, polypropylene and other engineered materials for durable, lightweight performance. 🔧
