Alpinestars SM3 Jettson Helmet — Size M, Gray

This helmet is engineered for motocross, enduro and off-road use with technologies optimized for ease of use, comfort and impact performance.

The thermo-injected shell incorporates a specially blended polymer with variable thicknesses to deliver an optimal balance of impact protection and light weight.

A low-friction coating on the inner EPS liner reduces rotational acceleration that can result from certain oblique impacts by acting as a slip plane similar to the brain's natural cerebrospinal fluid.

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

Ten intake vents and seven exhaust ports maximize ventilation and heat transfer for demanding riding sessions.
