Alpinestars S-M3 Heat Silver Blue Black Matt Motocross & Enduro Helmet
Alpinestars S-M3 Heat Silver Blue Black Matt - Ultra-Ventilated Off-Road Helmet with Modern Matte Look
Comfort, safety and futuristic matte styling: the S-M3 Heat Matt is with you every step of the way, ready for MX, enduro or committed off-road riding.
With its modern, matte silver, blue and black look, the Alpinestars S-M3 Heat Silver Blue Black Matt helmet makes a style statement without compromising technique. Designed for MX, enduro and off-road enthusiasts in search of performance, it incorporates the best Alpinestars innovations to offer you a helmet that's complete, protective and pleasant to wear, even during the most demanding sessions.
Its thermo-injected shell is made from a blend of reinforced polymers, with variable thicknesses to effectively absorb impact while maintaining a light weight. Inside, you'll find a 5-part, 4-density EPS for targeted impact dissipation.
And to deal with oblique impacts? Alpinestars has integrated a patented low-friction internal coating, inspired by the cerebrospinal fluid of the brain, to limit the effects of rotational forces. It's discreet, but a real step forward in terms of safety.
The helmet is also ultra-ventilated, with 10 air intakes and 7 extractors, plus a visor that channels the flow of air. And if you fall, it cleverly detaches to protect the back of your neck. Add to that an interior made from recycled materials, adjustable foams, and a chin bar reinforced to Alpinestars' in-house standards... You've got a helmet built to last and to protect you, ride after ride.
