Why the Alpinestars Sm3 Radium Helmet Matters

When it comes to off-road riding, safety is essential. The Alpinestars Sm3 Radium Helmet is equipped with features that prioritize rider protection. One of the standout aspects of this model is its compliance with the ECE 2206 certification. This certification ensures that the helmet meets stringent safety standards for worldwide use, providing riders with peace of mind while they tackle challenging terrains.

Advanced Impact Protection

Another remarkable aspect of the Alpinestars Sm3 Radium Helmet is its patented low-friction coating applied to the inner lining of the main EPS (Expanded Polystyrene) shell. This technology reduces rotational acceleration forces that can occur during oblique impacts, mimicking the brain’s natural defense mechanism against such forces. This layer acts as a sliding plane, providing an additional level of protection for the rider.

Lightweight and Comfortable

Weighing in as a lightweight option, the Alpinestars Sm3 Radium Helmet features a thermo-injected shell made from a special blend of polymers. This design incorporates various thickness levels to offer an optimal combination of impact protection and lightness. Riders can enjoy long hours of use without added bulk, making it an ideal choice for extended rides.

The helmet boasts a patented visor release system that allows the visor to detach with a predetermined amount of force during an impact. This innovative feature significantly reduces neck forces on the rider, enhancing safety during falls or collisions. Additionally, the helmet is designed with maximized ventilation in mind, featuring 10 air intakes and 7 exhaust ports. This ensures high levels of heat exchange, keeping the rider cool and comfortable even in the most demanding conditions.
