ALPINESTARS(MX) SM3 Heat Helmet — L, Yellow

Engineered for MX, enduro and off-road use, this design blends ease of use, comfort and impact performance. 🔥

The thermo-injected shell employs a special polymer blend with varying thicknesses to deliver optimal impact protection while keeping overall weight low.

A patented low-friction coating on the inner EPS liner reduces rotational acceleration from oblique impacts by creating a slip plane that mimics the brain's own protective fluid. 🧠

The patented visor release system ensures the visor releases at a predetermined force, helping to reduce forces on the neck during an impact.

Ventilation is maximized with ten inlets and seven exhaust ports for high levels of heat transfer and continuous airflow.

Materials are precisely balanced for durability and energy management: 48% acrylonitrile-butadiene-styrene, 20% polyurethane, 16% polystyrene (EPS) and a mix of engineered components for reinforced performance.
