Alpinestars S-M3 Solid Black Matt Motocross & Enduro Helmet
Alpinestars S-M3 Solid Black Matt - Discreet elegance and top-level off-road protection
A timeless, matte-finish off-road helmet designed for action and built for the demands of motocross and enduro.
With its sober, modern look and matte black finish, the Alpinestars S-M3 Solid Black Matt helmet is much more than a stylish accessory. It's a real concentrate of technology designed to offer you a high level of protection, optimum comfort and intelligent ventilation, whether you're riding on the track, in the forest or on the trails.
Its thermo-injected shell, based on reinforced polymers, adopts a variable thickness structure to optimize shock absorption while keeping weight down (1430g ECE). Its EPS padding is composed of 5 zones with 4 different densities for precise impact dissipation.
But that's not all. The S-M3 also incorporates a patented low-friction inner lining, capable of limiting the rotational forces caused by oblique impacts. A real plus for your safety, inspired by the way cerebrospinal fluid works.
You'll also benefit from exceptional airflow (10 inlets and 7 outlets), a visor that channels the flow while releasing in the event of impact, and a comfortable interior made from recycled materials that can be disassembled, washed and adjusted.
