Due to regulations for transport of dangerous goods by air (IATA) and road (ADR), consumers are not permitted to ship Tech-Air® products themselves for return or servicing. In the event of a return or service request you must therefore deliver the goods in person to one of our Tech-Air® Hubs. Please ensure you first contact our Customer Care team to receive confirmation of the correct Hub and approval before visiting.
Tech-Air® Hubs are currently available in select countries. Additional locations across Europe will be launched soon.
Please use the map below to find your closest Tech-Air® Hub.
By purchasing a Tech-Air® product on the Alpinestars website, you acknowledge and accept this return policy. If you still decide to ship your Tech-Air® product as a return, Alpinestars Spa will not be held responsible for the transit of such goods and will not accept them as returns. For this reason, no refund will be issued.
For any questions, feel free to contact our Customer Care team before making your purchase.
Expertly engineered for MX and Enduro riding, the S-M3 Solid Helmet is a lightweight off-road solution designed for superior impact protection and rider comfort. Featuring a thermo-injected shell with a patented visor release system and a low-friction internal coating, it effectively reduces rotational acceleration forces during impacts. This ECE 22.06 certified helmet includes a maximized ventilation system with 17 ports and integrated hydration tube channels.
Key Features
Advanced Shell Construction: Features a thermo-injected shell with a specialized polymer blend and engineered thickness to provide the optimal balance of lightweight performance and impact protection (1430g ECE / 1460g DOT).
Maximized Ventilation: Optimized airflow and heat exchange via 10 intake vents and seven exhaust ports for superior rider cooling.
Rotational Acceleration Force Protection: Patented low-friction coating on the internal EPS liner acts as a slip plane to reduce rotational forces during oblique impacts, mimicking the brain's natural defenses.
Patented Visor Release: Engineered system ensures the visor detaches with a pre-determined force to minimize neck strain and rotational energy during an impact.
Protection
Engineered inner and outer surfaces designed to minimize the effects of oblique impacts.
Five-piece EPS inner liner featuring four different densities for optimized impact management and performance.
Integrated hydration tube channels within the cheek pads for seamless performance and convenience.
Comfort liner manufactured using recycled materials to reduce environmental impact.
