Alpinestars Supertech M10 Solid Helmet — 2XL, Black

The S-M10 shell sizing solution ensures each fit size uses an appropriate shell to improve comfort, reduce overall weight, and optimize impact performance.

Surface curvature promotes reduced friction on impact, allowing deflection and transfer of energy away from the skull and neck to minimize force transmission.

The helmet's streamlined aerodynamic profile is free of external channels or load points that could compromise integrity during impact.

Fitted with E-2, the latest generation of MIPS, an integrated low-friction layer that reduces rotational motion transferred to the brain from angled impacts.

The chin bar base is sculpted and raised to provide relief at the collarbone, while a soft EPS liner extends beyond the shell and is covered by a flexible rubber compound to further reduce the risk of collarbone injury.

An A-Head Fitment System allows easy adjustment of helmet angle and height for a personalized fit.

Ultra-ventilated design with 28 intake and exhaust ports (18 intakes, 10 exhausts) for continuous airflow and heat management.

Eject removal technology and an Emergency Release System (ERS) enable controlled helmet removal after a crash, and removable semi-soft polymer side pads help spread impact energy to reduce localized forces.

Rotational acceleration and oblique impact performance are engineered into the design, and the construction combines multiple advanced materials to balance protection and weight.
