Alpinestars SM3 - Off-Road Performance and High-Tech Protection for Off-Road Bikers

Push the limits of off-roading with the Alpinestars SM3 helmet: lightweight, protective and ultra-ventilated for demanding MX and Enduro riders.

The Alpinestars SM3 helmet is designed for serious off-road riders, from MX to steep enduro trails. Underneath its sharp design, it embeds advanced technologies that optimize your comfort and safety without ever weighing down the ride. Its thermo-injected, variable-density shell offers excellent impact protection, while keeping the weight down to just 1430g in the ECE version.

This off-road helmet also boasts outstanding ventilation, with 10 air inlets and 7 exhaust outlets. The result: constant air flow, even in the most demanding conditions. In terms of safety, Alpinestars has incorporated a patented low-friction layer in the EPS lining, which mimics the natural role of cerebrospinal fluid in the event of an oblique impact. And for even greater peace of mind, the visor is designed to detach with a calibrated force, limiting twisting of the neck.

The SM3 is the choice of demanding riders who want to ride hard, without compromising comfort, safety and innovation.
