Yamaha S-M3 Youth Helmet ECE 22.06

• 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.
