Expertly designed for off-road racing, the S-M7 Deed Helmet is Alpinestars' advanced solution for riders seeking a lightweight, high-ventilation head protector. Featuring a multi-layer composite shell and patented PLASMA technology, it delivers superior impact dissipation and critical collarbone protection. This ECE 22.06 certified helmet includes the A-Head Fitment System and a 15-Joule visor release for optimized safety and a personalized performance fit.

Aerodynamic shell: Smooth, channel-free exterior eliminates snag points and potential load concentrations to help preserve shell integrity during off‑road spills.
Anti‑snag curvature: Curved profile promotes controlled sliding and helps deflect forces away from the head, neck, and spine for reduced injury risk.
PLASMA impact zones: Alpinestars PLASMA technology in the lower side pads adds high‑performance shock absorption around critical collarbone areas.
Crash‑tuned visor release: Patented system detaches the visor at a defined impact threshold (above 15 Joules) to help limit rotational loading and prevent visor damage.
Optimized shell sizing: Three external shell sizes across XS–XXL deliver a proportional, anatomical fit that reduces bulk and enhances control.
Hydration routing: Integrated side channels guide a drink tube cleanly into the helmet for on‑the‑go hydration without distraction.

Multi-layer composite shell (fiberglass, carbon, aramid) engineered for impact energy dissipation, controlled sliding, and high energy absorption in crash scenarios.
Patented A-Head Fitment System allows precise angle and height positioning of the helmet on the head to optimize protective coverage and stability during impacts.
Eject Removal System Ready: designed to accept an emergency removal insert at the crown to facilitate safer helmet extraction by first responders.
Cheek pad interchangeability across all shell sizes enables secure stabilization of the head for consistent impact performance and retention.
Homologations: available in ECE 22.06 and DOT certified versions.
Energy-deflecting curved shell profile reduces friction and helps redirect impact forces away from the skull, neck, and spine.
Patented Visor Release System designed to detach when subjected to impact energy greater than 15 Joules to mitigate rotational loading and reduce the risk of secondary injury.
PLASMA technology integrated into side pads provides targeted shock absorption in critical contact zones.
Engineered for linear and oblique impact attenuation; internal EPS shape and patented coating deliver rotational impact mitigation, reducing peak rotational acceleration by 76% beyond ECE 22.06 requirements.
Profiled chin bar provides integrated frontal impact protection.

Shell construction utilizes advanced molding technology with a pre‑preg multi‑layer composite lay‑up combining fiberglass, carbon fiber, and aramid fiber.
Engineered outer shell profile with controlled ply orientations manages linear and oblique impact loads.
Internal shape and EPS liner with proprietary low‑friction coating, working with comfort liner surfaces, provide rotational impact mitigation.
Patented low‑friction coating technology reduces rotational acceleration transmitted to the head, exceeding ECE 22.06 requirements by up to 76%.
Profiled chin bar with integrated reinforcement for targeted frontal impact structure.
PLASMA energy‑dissipating inserts integrated at the lower shell side pads for collarbone‑area load management.
Approximate weight: 1280 g (ECE size M).
