Alpinestars SM-3 Kids Helmet

Alpinestars S-M3 Yamaha

The Supertech S-M3 helmet was specially developed for teenagers and younger riders. It is optimized for MX, enduro, and off-road use and features a range of technologies and innovations adopted from Alpinestars adult helmets to provide the ideal combination of performance, protection, and comfort.

Features

• This lightweight helmet features a thermally injected shell made from a special polymer blend with varying thicknesses, providing an optimal combination of impact protection and low weight
• The lightweight outer shell is made from advanced, impact-resistant thermoplastic and is available in three sizes (Youth Small, Youth Medium, and Youth Large). The SM3 Youth weighs 1060 g (ECE) and 1170 g (DOT)
• Separate shell versions for DOT and ECE requirements; the DOT-certified version of the helmet's inner shell is made from a fiber composite material positioned between the outer shell and the EPS liner to provide maximum impact protection
• The fit can be adjusted to the rider's head using the helmet shell and cheek pads, which are available as replacement parts in various thicknesses
• The Youth Medium (YM) and Youth Large (YL) sizes have the same EPS size, so riders who start with a YM helmet can later adjust it to a Youth Large size as they grow using replacement top and cheek pad parts
• The Youth Small (YS) has a smaller EPS size and can only be adjusted using the cheek pads. Alpinestars' extensive research has shown that children who wear a YS size are very small, typically 3 to 4 years old, and therefore require a special fit
• The multi-density liner ensures that the helmet is equipped with the right density in the right places to better absorb impacts while reducing overall weight
• The inner and outer surfaces are designed to minimize the effects of oblique impacts
• Alpinestars' patented low-friction coating is applied to the inner part of the main EPS layer to reduce rotational acceleration forces that can occur during certain oblique impacts. This layer essentially acts as a sliding surface, mimicking the low-friction cerebrospinal fluid that represents the body's natural defense against oblique impacts
• Maximum ventilation and a high level of heat transfer thanks to 10 air intakes and 7 exhaust vents
• The peak is designed to direct air into the vents to improve airflow
• The patented peak release system ensures that the peak is released with the correct, predetermined amount of force, effectively reducing the forces acting on the rider's neck during an impact
• The comfort liner is made from recycled materials for a lower carbon footprint
• The helmet's cheek pads feature integrated channels for a hydration hose, ensuring comfort and performance
• The soft textile chin strap is 25 mm wide and ensures optimal safety and rider comfort

Protection

• Alpinestars has introduced an in-house standard for the Supertech S-M3 Youth to test the helmet's chin area under conditions more severe than the homologation standard. To pass Alpinestars' standards, both the shell thickness and the structure of the helmet design itself were optimized in the chin area for superior impact performance
• Equipped with an emergency system and removable cheek pads for safe and easy removal while the helmet is still on, while the 3D-molded foam ensures rider comfort
• Double stainless steel D-rings ensure a firm and secure fit
• The SM3 helmet complies with both DOT certification and ECE 2206 homologation for worldwide use
