The Alpinestars Youth SM3 Helmet combines advanced impact protection, lightweight performance, and adjustable comfort for young riders. This medium-size helmet features a thermo-injected shell made from a specialized polymer blend with varying thicknesses to help deliver an effective balance of strength and reduced weight. The technologically advanced impact-resistant thermoplastic outer shell works with a multiple-density inner liner to provide the appropriate level of impact absorption in key areas. The Alpinestars SM3 helmet is designed for motocross and off-road riding and is finished in Falcon Blue, White, Black, and Pink Fluo. Manufacturer and vendor part number: 8301327-7347-YM.
The helmet’s inner and outer surfaces are engineered to help minimize 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. The visor release system is engineered to release at a predetermined force, helping reduce forces transferred to the rider’s neck during an impact. Stainless steel D-rings provide a secure, dependable fit, while the 25 mm soft textile chin strap supports rider comfort and safety.
Ten intake vents and seven exhaust ports maximize ventilation and heat exchange, with the visor designed to direct airflow into the helmet’s ventilation channels. The removable crown and cheek pads allow the fit to be tailored to the rider and can be replaced with optional thicknesses. Hydration tube channels are integrated into the cheek pads for convenient use during riding. The comfort liner uses recycled materials to help reduce environmental impact, and the Emergency Release System with removable cheek pads supports safer helmet removal by trained personnel. Three-dimensional contoured foam enhances comfort and fit for youth riders seeking dependable off-road protection.
