INNOVATIVE FRICTION COATING

Alpinestars patented low friction coating is applied tothe inner part of the main EPS liner to reduce therotational acceleration forces that can result from certainoblique impacts. This layer essentially acts as a slip plane to mimic thebrain’s own low friction cerebrospinal fluid, which is the body’s naturaldefense against oblique impacts.

LIGHTWEIGHT OUTERSHELL

This lightweight helmet features athermo-injected shell incorporating a special polymer blendenhanced by varying degrees of thickness that is engineeredto deliver the optimal combination of impact protection and lightweight.
