Description
The Alpinestars SM3 Solid Helmet in Gloss White is engineered for off-road excellence, combining safety, comfort, and performance. Conforming to both DOT and ECE 22.06 certifications, this helmet ensures global safety compliance. Its construction includes a varied thickness shell for optimized protection and a 6-piece EPS liner with three densities to manage impact forces. The polished inner EPS liner features a low-friction coating to reduce rotational acceleration from oblique impacts. Enhanced with a slip-plane layer, the helmet mimics the brain’s natural defense system. With 10 air inlets and 7 exhaust ports, it provides superior ventilation for long riding sessions. A patented breakaway visor minimizes neck forces during impact. Designed with comfort in mind, the SM3 offers a snug, breathable fit and optional cheek pad customization.
