Alpinestars SM3 Youth Jettson ECE/DOT Motorcycle Helmets

Anatomically engineered and profiled specifically for younger riders, the all-new SM3 Youth Helmet is optimized for MX, Enduro, and Off-road use. This lightweight helmet incorporates a technologically advanced polymer blend and high-end safety features derived from Alpinestars adult racing range. Designed to provide an optimal blend of impact protection and comfort, it ensures that the next generation of riders stays safe on the track.

Advanced Shell Construction and Weight Optimization

• Manufactured from a technologically advanced impact resistant thermoplastic for a lightweight yet strong structure.

• Available in three dedicated shell sizes: Youth Small, Youth Medium, and Youth Large.

• The ECE version weighs approximately 1060g, while the DOT version weighs 1170g.

• Features varying degrees of shell thickness to deliver a precise combination of protection and weight reduction.

• DOT certified versions include a composite fiber layer between the outer shell and EPS liner for maximum impact resistance.

Specialized Impact Absorption and Rotational Safety

• Equipped with a multiple density inner liner to provide the correct density in critical impact zones.

• Inner and outer surfaces are specifically engineered to minimize the effects of oblique impacts.

• Features a patented low friction coating on the EPS liner to reduce rotational acceleration forces.

• The slip plane technology mimics the body natural cerebrospinal fluid defense system.

• Optimized shell structure in the chin area exceeds standard homologation requirements for superior safety.

Ventilation and Airflow Management

• Maximized ventilation system features 10 intake inlets and seven exhaust ports for high levels of heat transfer.

• Visor design acts as a funnel to direct fresh air directly into the intake ports.

• Patented visor release system ensures the visor detaches with a pre-determined force during a crash.

• Strategic airflow channels help keep junior riders cool even during high-intensity racing.

• Integrated hydration tube channels in the cheek pads provide convenient performance hydration.

Customizable Fit and Growing Rider Support

• Youth Medium and Youth Large sizes share the same EPS, allowing for easy size conversion as the child grows.

• Crown and cheek pads are available in different thicknesses to tailor the fit to the rider head shape.

• Youth Small features a dedicated smaller EPS size designed specifically for very young riders (typically 3 to 4 years old).

• 3D contoured foam ensures maximum comfort and stability during aggressive movements.

• Comfort liner is constructed using recycled materials to promote a lower carbon footprint.

Emergency Features and Secure Retention

• Equipped with an Emergency Release System (ERS) for safe and easy cheek pad removal by medical staff.

• Stainless steel D-rings provide a tight, reliable, and secure fitment for every ride.

• Soft 25mm textile chin strap ensures optimal rider comfort and safety.

• Removable and washable interior components maintain hygiene and freshness.

• Global safety compliance with both DOT certification and ECE 22.06 homologation.
