ALPINESTARS Youth SM3 Jettson Helmet (Gloss Black/Gray/Purple) – Size S Built for young riders who demand serious protection, the ALPINESTARS Youth SM3 Jettson Helmet combines a lightweight design with advanced impact engineering and aggressive off-road ventilation. Key Features Thermo-injected shell with a special polymer blend and varying thickness for the ideal balance of impact protection and low weight. Lightweight thermoplastic outer shell engineered for impact resistance. Tailored fit with crown and cheek pads available as spare parts in different thicknesses. Multiple density inner liner for correct energy absorption where it matters most. Design focused on minimizing oblique impact effects. Low-friction slip-plane layer on the EPS liner to help reduce rotational acceleration during certain oblique impacts. Maximized ventilation with 10 inlets and 7 exhaust ports; visor channels direct airflow. Visor release system set to release with predetermined force to reduce neck loads in impacts. Comfort liner made with recycled materials for a lower carbon footprint. Hydration tube channels integrated into the cheek pads. 25 mm soft textile chin strap for comfort and security. Emergency Release System with removable cheek pads for easier safe removal while worn. Stainless steel D-rings for a secure fit.

Features a thermo-injected shell incorporating a special polymer blend enhanced by varying degrees of thickness that is engineered to deliver the optimal combination of impact protection and light weight
Lightweight outer shell constructed from a technologically advanced impact resistant thermoplastic
The fit can be tailored to the rider’s head thanks to the helmet’s crown and cheek pads, which are available as spare parts in different thicknesses
The multiple density inner liner ensures the helmet is equipped with the correct density in the correct area for enhanced impact absorption, while also helping to reduce overall weight
The inner and outer surfaces are engineered to minimize the effects of oblique impacts
Low friction coating is applied to the inner part of the main EPS liner to reduce the rotational acceleration forces that can result from certain oblique impacts— this layer essentially acts as a slip plane to mimic the brain’s own low friction cerebrospinal fluid, which is the body’s natural defense against oblique impacts
Maximized ventilation and high levels of heat transfer exchange thanks to ten inlets and seven exhaust ports
The visor has been designed to direct air into the ports for enhanced airflow
Visor release system ensures the visor is released with the correct pre-determined amount of force, effectively reducing the forces on the rider’s neck during an impact
Comfort liner is constructed using recycled materials for a lower carbon footprint
Hydration tube channels are integrated into the helmet’s cheek pads for convenience and performance
Soft textile chin strap is 25 mm for optimal safety and rider comfort
Equipped with an Emergency Release System and removable cheek pads to permit the safe and easy removal of the cheek pads while the helmet is still on, while the 3D contoured foam ensures rider comfort
Stainless steel D-rings ensure a tight and secure fit
