Description+-
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.

The innovative patented Alpinestars low-friction lining is applied to the inside of the main EPS shell to reduce rotational acceleration forces during certain oblique impacts.
This layer acts as a sliding plane, mimicking cerebrospinal fluid and the brain's natural defense against oblique impacts.
Patented visor release system ensuring controlled opening and reducing forces on the neck during an impact.
Optimized ventilation and high thermal exchange thanks to 10 air intakes and 7 exhausts.
