Anatomically engineered for younger riders, the all-new S-M3 Youth Helmet is Alpinestars' most advanced off-road head protection for the next generation of racers. Featuring a lightweight, thermo-injected shell and a multi-density EPS liner, it is ECE 22.06 certified to provide superior impact absorption. This race-ready helmet delivers optimized ventilation, a patented visor release system, and a customizable fit to grow with the rider.

Thermo-injected shell: Features a specialized polymer blend with engineered thickness to deliver an optimal balance of high-impact protection and reduced weight.
Advanced thermoplastic construction: Lightweight outer shell is impact-resistant and available in three dedicated youth sizes (YS, YM, YL), weighing 1060g (ECE) and 1170g (DOT).
Region-specific safety: Separate shell versions for DOT and ECE requirements; the DOT version includes a composite fiber layer between the shell and EPS liner for maximum impact resistance.
Tailored fitment: Crown and cheek pads are available in various thicknesses as spare parts, allowing riders to customize the internal fit for comfort and stability.
Growth-compatible sizing: Youth Medium (YM) and Youth Large (YL) share the same EPS size, enabling the helmet to be reconfigured as the rider grows by simply swapping internal pads.
Dedicated Youth Small (YS) fit: Features a smaller, specific EPS size designed for the youngest riders (typically ages 3 to 4) to ensure a safe and proportionate fit.

Multiple density inner liner provides targeted impact absorption in key areas while reducing overall weight.
Inner and outer surfaces are engineered to minimize the effects of oblique impacts.
Alpinestars patented low friction coating on the main EPS liner reduces rotational acceleration forces by acting as a slip plane.
Patented visor release system ensures the visor detaches with a pre-determined force to reduce neck loading during an impact.

Engineered to Alpinestars' new safety standard, featuring an optimized shell thickness and structure in the chin area for superior impact performance.
Equipped with an Emergency Release System and removable 3D contoured foam cheek pads for safe and easy helmet removal.
Secure closure system utilizing stainless steel D-rings for a consistent and tight fit.
Fully conforms to ECE 22.06 homologation and DOT certification for global use.
