Alpinestars Supertech M10 Solid Helmet — XS, Black Gloss

Designed for off-road riders, this helmet uses shell sizing to provide each fit size with an appropriately scaled shell for improved comfort, reduced weight, and enhanced impact performance.

Surface curvature and a streamlined aerodynamic profile promote deflection and reduce friction on impact, directing energy away from the skull and neck.

An integrated E-2 low-friction layer reduces rotational motion transferred to the brain from angled impacts.

The chin bar is sculpted to clear the collarbone, while a soft EPS liner extends beyond the shell and is covered by a flexible rubber compound to lower the risk of collarbone injury.

Ultra-ventilated with 28 intake and exhaust ports, removable semi-soft polymer side pads to help spread impact energy, an emergency release system, and an eject helmet removal system for safe extraction.

Overall design focuses on rotational acceleration and oblique impact performance, with an adjustable fitment system for easy angle and height tuning.
