Helmet Alpinestars S-M3 Kids Wurx Black Yellow

The Alpinestars S-M3 Youth Wurx kids' helmet offers safety and comfort for young riders.

Specifications:

• Thermoinjected shell: features a special polymer blend with variable thicknesses, designed to provide the optimal combination of lightness and impact performance.
• Thermoplastic construction: lightweight outer shell is made from a technologically advanced, impact-resistant thermoplastic, available in three sizes (Youth Small, Youth Medium, and Youth Large) to optimize fit and weight; the SM3 Youth weighs 1060 g (ECE) and 1170 g (DOT).
• Specific DOT/ECE versions: shells have separate versions to meet DOT and ECE requirements; in the DOT certified version, the inner shell includes a composite fiber assembled between the outer shell and EPS liner to maximize impact protection.
• Customizable fit: crown pads and cheek pads, available as spare parts in different thicknesses, allow fine-tuning of the helmet to the rider’s head for enhanced comfort and support.
• Growth system YM/YL: Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size, allowing you to start with a YM helmet and upgrade to Youth Large as the rider grows by switching out the crown and cheek pads.
• YS-specific fit: Youth Small (YS) size uses a smaller EPS and can only be customized with cheek pads; Alpinestars' extensive research shows that children wearing a YS size are typically 3 to 4 years old, requiring a specific fit.
• NEW ALPINESTARS SAFETY STANDARD: Alpinestars has introduced a new internal standard for the SM3 Youth to subject the helmet chin bar to more demanding conditions than the homologation standard; to meet this new standard, both shell thickness and chin area structure have been optimized for superior impact performance.
• Equipped with an emergency release system and removable cheek pads to allow safe and easy removal of the pads while the helmet remains on.
• Stainless steel D-rings ensure a secure and firm fit.
• The SM3 helmet meets both DOT and ECE 22.06 certification for worldwide use.
• Multi-density inner liner guarantees the helmet has the right density in the right area to improve impact absorption, while helping to reduce overall weight.
• Interior and exterior surfaces are designed to minimize the effects of oblique impacts.
• Alpinestars' patented low-friction coating is applied to the inside of the main EPS liner to reduce rotational acceleration forces that can result from certain oblique impacts. This layer essentially acts as a slip plane to mimic the brain’s low-friction cerebrospinal fluid, the body’s natural defense against oblique impacts.
• Maximized ventilation and high levels of heat exchange thanks to 10 intakes and seven exhausts.
• The visor is designed to channel air to the intakes and enhance airflow.
• The patented visor release system ensures the visor releases with the correct preset amount of force, effectively reducing forces on the rider’s neck during an impact.
• The Comfort liner is made with recycled materials for a reduced carbon footprint.
• Hydration tube channels are integrated into the helmet cheek pads for improved comfort and performance.
• The soft textile chinstrap is 25 mm for optimal rider safety and comfort.
