The Alpinestars Youth SM3 Fray Helmet is designed for young off-road riders who need dependable impact protection, a secure fit, and effective ventilation. This large helmet features a thermo-injected shell made from an advanced impact-resistant thermoplastic polymer blend. The shell uses varied thicknesses to balance lightweight performance with structural protection. Its multiple-density inner liner places the appropriate density in key areas to help absorb impact energy while minimizing overall weight.
Engineered inner and outer surfaces help reduce the effects of oblique impacts. A low-friction coating on the main EPS liner creates a slip-plane effect intended to reduce rotational acceleration forces during certain angled impacts. Ten intake vents and seven exhaust ports promote airflow and heat exchange, while the visor is shaped to direct air toward the ventilation openings. The visor release system is designed to release at a predetermined force, helping reduce forces transferred to the rider’s neck during an impact.
The Alpinestars Youth SM3 also includes a comfort liner made with recycled materials, integrated hydration tube channels in the cheek pads, and a soft 1-inch chin strap for comfort and safety. Removable cheek pads and the Emergency Release System support safer helmet removal after an incident. Three-dimensional contoured foam enhances comfort, while stainless steel D-rings provide a secure, adjustable closure. The crown and cheek pads are replaceable in different thicknesses, allowing the fit to be tailored to the rider’s head. This large youth model is finished in Gloss Red, Yellow Fluo, and Black and carries manufacturer and vendor part number 8301625-3051-YL.
