Product information
- ECE-2206 Certified
The S-M3 helmet complies with ECE 2206 certification for worldwide use.
The patented visor release system ensures that the visor is released with the correct predetermined amount of force, effectively reducing neck forces on the rider during an impact.
Maximized ventilation and high levels of heat exchange thanks to 10 air intakes and 7 exhaust ports.
Alpinestars' patented low-friction coating is applied to the inner lining of the main EPS lining to reduce rotational acceleration forces that can result from certain oblique impacts.
This layer essentially acts as a sliding plane to mimic the brain's low-friction cerebrospinal fluid, which is the body's natural defense against oblique impacts.
This lightweight helmet features a thermo-injected shell incorporating a special blend of polymers enhanced by various thickness levels, designed to offer the optimal combination of impact protection and lightness.
