Helmet Alpinestars S-M3 Youth Matte Black

The children's helmet Alpinestars S-M3 offers safety and comfort for younger riders.

Specifications:

• NEW ALPINESTARS SAFETY STANDARD
• Alpinestars has introduced a new internal standard for the SM3 Youth to subject the helmet's chin bar to more demanding conditions than those required by the standard approval; to meet the new Alpinestars standards, both the shell thickness and the chin bar design structure have been optimized to deliver superior performance against impacts.
• Equipped with an Emergency Release System and removable cheek pads that allow safe and easy removal of the cheek pads with the helmet still in place.
• Stainless steel D-rings ensure a firm and secure fastening.
• The SM3 helmet meets both DOT certification and ECE 22.06 approval for worldwide use.
• The multi-density inner liner ensures the helmet has the proper density in the right areas to enhance impact absorption, as well as help reduce overall weight.
• The interior and exterior surfaces are designed to minimize the effects of oblique impacts.
• A low-friction coating patented by Alpinestars is applied to the inner surface of the main EPS liner to reduce rotational acceleration forces that may result from certain oblique impacts. This layer essentially acts as a slip plane that mimics 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 exhaust ports.
• The visor is designed to direct air into the openings to enhance airflow.
• The patented visor release system ensures it detaches with the proper predetermined amount of force, effectively reducing forces on the rider’s neck during an impact.
• The comfort liner is built with recycled materials to reduce carbon footprint.
• Channels for hydration tubes are integrated into the helmet's cheek pads for greater convenience and performance.
• The soft textile chin strap is 25 mm for optimal rider safety and comfort.
• Thermoinjected shell: incorporates a special blend of polymers with variable thicknesses, designed to provide the optimal combination of lightness and off-road performance.
• Lightweight construction: the outer shell in advanced impact-resistant thermoplastic is available in three shell sizes (Youth Small, Youth Medium, and Youth Large), helping reduce weight for enhanced rider comfort; the SM3 Youth weighs 1060 g (ECE) and 1170 g (DOT).
• Specific shell versions: features independent versions for DOT and ECE requirements, ensuring construction tailored to each homologation; in the DOT version, the inner shell incorporates a composite fiber assembled between the outer shell and the EPS liner.
• Customizable fit: the helmet can be precisely adapted to the rider's head with Crown Pads and Cheek Pads available as spare parts in various thicknesses, for a more accurate and durable fit.
• Evolving sizing system: Youth Medium (YM) and Youth Large (YL) sizes share the same EPS size, allowing a rider using YM to later configure the helmet to Youth Large as they grow, using replacement Crown Pads and Cheek Pads.
• Youth-specific fit: the Youth Small (YS) size uses a smaller EPS size and can only be customized with the Cheek Pads, offering a dedicated fit for very young riders, usually 3 to 4 years old.
