The Alpinestars Supertech family of helmets was designed with the goal of creating the most advanced, protective, and performance-enhancing helmets possible for riders worldwide. The S-M10 helmet, engineered by Alpinestars' Helmet Development team, offers a perfect blend of excellent ventilation and unsurpassed comfort, all while maintaining the lightest weight possible without compromising on any other front.

The S-M10's design features a smooth, attractive, and aerodynamic profile that is streamlined and free of any external channels or features that could act as a load point in an impact or compromise the overall integrity of the helmet's construction. The surface curvature promotes reduced friction on impact, allowing for deflection and the most efficient transfer of energy to protect the rider's head from direct force to the skull and referred to the neck and spinal column.

The helmet's shell construction utilizes a highly advanced molding technology with a multi-composite combination. The first layer is a 3K Carbon, a high-density carbon outer layer that improves strength and efficiency of energy dissipation over the shell. The second layer is a Uni-directional carbon composite layer that gives significantly greater radial strength around the shell, preventing compression but allowing controlled deflection for reducing transmitted impact energy. The third layer is an Aramid fiber layer, which provides critical protection.

The S-M10 is an ultra-ventilated helmet, featuring 28 individual intake and exhaust ports, not including the eye port, with 18 intakes and 10 exhausts. This extensive ventilation system ensures exceptional airflow and comfort for the rider.

In terms of weight, the S-M10 is remarkably lightweight, weighing only 1260g for the ECE version and 1360g for the DOT version in a size medium. With the side pads installed, the helmet weighs 1310g, and with the visor extension, it weighs 1370g.

For added protection, the S-M10 is equipped with removable side pads made from a semi-soft polymer. These pads provide a larger contact area to help spread impact energy, further enhancing the helmet's protective capabilities.

The S-M10 also features the Multi-directional Impact Protection System (MIPS), a technology designed to reduce the rotational forces transferred to the head in the event of an impact, providing an additional layer of protection for the rider.

In summary, the Alpinestars Supertech S-M10 helmet is a true masterpiece of engineering, combining advanced materials, cutting-edge ventilation, and unparalleled protection to create the ultimate riding companion for discerning riders worldwide.
