Alpinestars SM3 Fray MX Helmet

The S-M3 helmet is designed for MX, Enduro, and Off-road, with innovations and technologies optimized for ease of use, comfort, and impact protection. Shell made from special thermo-injected polymer with variable thicknesses, designed to provide optimal impact protection and reduced weight. The innovative low-friction liner patented by Alpinestars is applied inside the main EPS liner to reduce rotational forces during oblique impacts. This layer acts as a slip plane to replicate the role of cerebrospinal fluid, the body's natural defense against oblique impacts. Patented visor release system ensuring deployment at a predetermined force, effectively reducing neck strain in the event of an impact. Optimized ventilation and high heat exchange thanks to 10 air intakes and 7 exhausts.
