ALPINESTARS SM3 HEAT HELMET ECE06/DOT YELLOW

Alpinestars SM3 Heat helmet ECE06/DOT yellow fluo/black glossy brings a high-visibility finish to a helmet engineered for MX, enduro, and off-road riding, built around advanced comfort and impact-protection technologies.

Maximized ventilation comes from 10 intake vents and seven exhaust ports for high levels of heat transfer exchange, while the thermo-injected shell uses a special polymer blend with varying degrees of thickness to deliver the optimal balance of impact protection and light weight — a size medium weighs 1430g in ECE spec and 1460g in DOT spec. An advanced 5-piece EPS inner liner with four specific densities optimizes impact management across the shell.

Alpinestars’ patented low-friction coating on the inner part of the main EPS liner acts as a slip plane that mimics the brain’s own cerebrospinal fluid, reducing rotational acceleration forces from oblique impacts. The patented visor release system detaches with a precise, pre-determined force to reduce forces on the neck during a crash, and the fit is tailorable through genuine spare crown and cheek pads in different thicknesses. Conforms to both DOT certification and ECE 22.06 homologation.
