Alpinestars S-M3 Radium Black White Gray Glossy Motocross & Enduro Helmet

Alpinestars S-M3 Radium Black White Gray Glossy - Racing design and enhanced safety for off-road use

A technical helmet, soberly stylish and built to take it. With the S-M3 Radium, you leave nothing to chance, neither on the track nor on the trails.

Sobriety in style, radicalism in protection: the Alpinestars S-M3 Radium Black White Gray Glossy helmet is aimed at the most demanding riders, whether they ride motocross, enduro or leisure off-road. It combines a sleek black, white and gray glossy look with cutting-edge technologies developed by Alpinestars.

The shell is made of multi-density thermo-injected polymer, with variable thicknesses to absorb impact effectively while keeping weight down (1430g in ECE). The EPS padding, cut into 5 parts with 4 different densities, distributes impact forces in a targeted manner.

And for oblique impacts, often underestimated, Alpinestars has integrated a patented low-friction inner lining, imitating cerebrospinal fluid and reducing rotational forces on the brain.

Add to this a formidable ventilation system (10 inlets, 7 outlets), a visor that channels air and intelligently detaches in the event of a fall, adjustable foams, a lining made from recycled materials, and you have a complete, reliable and comfortable helmet for all your sessions.
