ALPINESTARS SM3 SOLID HELMET ECE06/DOT WHITE
Alpinestars SM3 Solid Helmet Ece06/dot White Glossy brings a clean, high-shine finish to a helmet engineered for MX, enduro, and off-road riding, built around advanced comfort and impact-protection technologies.
Five EPS inner parts across four densities effectively manage volume and impact performance, while the thermo-injected shell’s special polymer blend and varying thickness deliver the optimal balance of protection and light weight — a size medium weighs 1430g in ECE spec and 1460g in DOT spec. Ten intake vents and seven exhaust ports maximize ventilation and heat transfer during hot laps.
Alpinestars’ patented low-friction coating on the inner main EPS liner acts as a slip plane that reduces rotational acceleration forces from oblique impacts, and a tougher in-house chin standard has optimized shell thickness and structure in the chin area for superior impact performance. The patented visor release system detaches with a precise, pre-determined force to reduce forces on the rider’s neck during a crash.
Hydration tube channels are integrated into the cheek pads, and the comfort liner is built from recycled materials for a lower carbon footprint. An Emergency Release System with removable cheek pads allows safe removal while the helmet is still on, and stainless steel D-rings with a soft 25mm textile chin strap keep the fit secure. Conforms to both DOT certification and ECE 22.06 homologation.
