Additional Details
Safety Certifications
One of the standout features of the Alpinestars Sm3 Radium Helmet is its compliance with the ECE 2206 certification. This certification ensures that the helmet meets stringent safety standards, making it suitable for worldwide use. Riders can trust that they are protected by a helmet that has undergone rigorous testing.
Advanced Impact Protection
Another remarkable aspect of the Alpinestars Sm3 Radium Helmet is its low-friction coating applied to the inner lining of the EPS shell. This innovative design mimics the brain’s natural defense against oblique impacts, reducing rotational acceleration forces that can occur during certain types of crashes. This technology is crucial for minimizing the risk of injury, making this helmet a top choice for serious riders.
Lightweight and Comfortable
Weighing in at a lightweight design, the Alpinestars Sm3 Radium Helmet features a thermo-injected shell made from a special blend of polymers. This construction not only provides excellent impact protection but also ensures that the helmet remains comfortable for extended wear. Riders can enjoy long hours on the trails without added bulk.
The helmet incorporates a patented visor release system that allows the visor to detach with a predetermined amount of force during an impact. This feature significantly reduces neck forces on the rider, enhancing safety during falls. Additionally, the helmet boasts maximized ventilation with 10 air intakes and 7 exhaust ports, ensuring optimal airflow and heat exchange, keeping you cool during intense rides.
