Alpinestars Supertech M10 Solid Helmet — XL, White

The S-M10 shell sizing delivers a tailored shell for each size, improving comfort, reducing weight, and optimizing impact performance.

Surface curvature and a smooth, aerodynamic profile promote deflection on impact and reduce load points that could transfer force to the neck and spine.

The helmet integrates E-2, the latest MIPS low-friction layer, to reduce rotational motion from angled impacts.

Chin-bar geometry includes a relief section raised to clear the collarbone, while the extended soft EPS liner is covered by a flexible rubber compound for added protection.

A-Head Fitment System lets riders adjust angle and height for a precise fit, and removable semi-soft polymer side pads increase contact area to help spread impact energy.

Ultra-ventilated construction features 28 intake and exhaust ports, plus emergency systems including ERS, emergency visor release, eject helmet removal, and visor extension for added protection.

Designed and tested for rotational acceleration and oblique impacts, the Supertech M10 Solid Helmet balances ventilation, protection, and fit.
