Alpinestars Supertech M10 Unite Helmet — XL, White gloss

The Supertech M10 Unite Helmet blends S‑M10 shell sizing and a streamlined aerodynamic profile to deliver a precise, comfortable fit for a wide range of riders. ✅

S‑M10 shell sizing gives each fit size its own appropriately scaled shell to reduce weight and improve impact performance without sacrificing comfort.

Surface curvature and a smooth, channel-free outer profile promote deflection on impact, helping to lower forces transmitted to the skull, neck, and spine.

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

The chin bar base is sculpted to clear the collarbone, while a soft EPS liner that extends beyond the shell and removable semi-soft polymer side pads help manage impact energy and reduce collarbone loading.

An A‑Head fitment system allows easy adjustment of helmet angle and height, and 28 intake and exhaust ports provide exceptional ventilation for long rides. ⚙️

Includes eject removal technology and an emergency visor release for rapid, safe helmet removal when needed.
