Alpinestars S-M3 Radium Black Red Fluo White Glossy

Alpinestars S-M3 Radium Black Red Fluo White Glossy - High-level protection and dynamic design for all terrains

Striking looks, onboard technology and extreme ventilation: the S-M3 Radium is ready for MX, enduro and all your off-road adventures.

Inspired by racing lines and designed for action, the Alpinestars S-M3 Radium Black Red Fluo White Glossy helmet is tailor-made for demanding motocross, enduro and off-road enthusiasts. With its mix of intense black, fluorescent red and brilliant white, it combines visual aggression with technical innovation.

Its thermo-injected shell uses a multi-density polymer with variable thicknesses, providing effective shock absorption while maintaining optimized weight (1430g in ECE). Inside, 5-zone, 4-density EPS enhances protection, while ensuring good energy distribution in the event of impact.

The patented low-friction coating, integrated into the EPS, limits rotational forces during oblique impacts, imitating the way cerebrospinal fluid works. It's the technical touch that makes all the difference off-road.

In terms of comfort, you can count on exceptional ventilation with 10 air intakes and 7 extractors, a controlled-release visor and an inner lining made from recycled materials. The helmet is adjustable thanks to interchangeable foams and is compatible with hydration systems.
