This large helmet features a lightweight thermo-injected shell made from an advanced impact-resistant thermoplastic polymer blend. Varying shell thicknesses help balance protection and weight, while the multi-density inner liner places the appropriate density in key areas to improve impact absorption.\u003c\/p\u003e\u003cp\u003eEngineered for modern riding conditions, the Youth SM3 uses low-friction surfaces on the inner and outer liner to help reduce the effects of oblique impacts. A low-friction coating on the primary EPS liner acts as a slip plane, helping reduce rotational acceleration forces. The visor release system is designed to release at a predetermined force to help reduce stress on the rider’s neck during an impact. The helmet also includes an Emergency Release System and removable cheek pads, allowing safer, easier cheek-pad removal while the helmet remains in place.\u003c\/p\u003e\u003cp\u003eVentilation is supported by 10 intake ports and 7 exhaust ports, with the visor designed to direct airflow into the helmet for improved heat transfer. The comfort liner uses recycled materials, while integrated hydration tube channels in the cheek pads add convenience during extended rides. A soft 1-inch chin strap improves comfort and safety, and stainless steel D-rings provide a secure, adjustable fit. The crown and cheek pads are available in different thicknesses as replacement parts, allowing the fit to be tailored to the rider. The Alpinestars Youth SM3 Radium is intended for youth off-road and powersports use and is supplied in matte gray, black, and yellow fluo.
