The Alpinestars SM3 Solid Helmet in Gloss Black is engineered for peak performance, safety, and comfort in off-road riding. Designed with a thermo-injected polymer blend shell of varied thickness, this helmet combines lightweight construction with optimal impact protection. It features a 6-piece EPS liner with three densities and Alpinestars' patented low-friction coating to reduce rotational acceleration forces. The slip-plane layer mimics the brain's natural defense mechanism against oblique impacts. With 10 intake and 7 exhaust vents, airflow is maximized for effective cooling. The liner is polished to reduce friction with the comfort liner, enhancing rotational impact management. Includes a breakaway visor and an adjustable fit via optional +/- 5 mm cheek pads. Conforms to both DOT and ECE 22.06 standards for global safety compliance.
