Overview

Alpinestars MX SM3 Helmets

Engineered for Enduro, MX, and off-road riding, the Alpinestars MX SM3 helmets integrates advanced technologies and innovations designed to enhance ease of use, comfort, and most importantly impact protection. With an advanced shell construction, the SM3 helmets feature a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and lightweight. Maximized ventilation and high levels of heat transfer exchange, thanks to 10 inlets and seven exhaust ports. Alpinestars patented low-friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain's own low-friction cerebrospinal fluid, which is the body's natural defense against oblique impacts. Patented visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider's neck during an impact. The SM3 helmets are available in a range of sizes and color options. Order the helmet in size you'd prefer.
