The Alpinestars Youth SM3 helmet is designed for young riders who need dependable off-road protection, a comfortable fit, and efficient ventilation. This solid matte black model is sized Medium and features a lightweight, thermo-injected outer shell made from an impact-resistant thermoplastic polymer blend. The shell uses varying thicknesses to help balance impact protection and reduced weight, making it suitable for demanding motocross and off-road riding.
Fitment can be customized with replacement crown and cheek pads available in different thicknesses. A multiple-density inner liner places the appropriate foam density in key areas to support impact absorption while helping control overall helmet weight. The helmet’s inner and outer surfaces are engineered to help minimize the effects of oblique impacts, while a low-friction coating on the main EPS liner is designed to reduce rotational acceleration forces by creating a slip-plane effect.
Ten intake vents and seven exhaust ports promote airflow and heat transfer, with the visor helping direct air toward the ventilation openings. 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 comfort liner uses recycled materials, and integrated hydration tube channels in the cheek pads support convenient use during extended rides.
Additional safety and comfort features include a soft 1-inch chin strap, stainless steel D-rings for a secure fit, removable cheek pads, and an Emergency Release System that supports safer helmet removal after an incident. Three-dimensional contoured cheek-pad foam improves comfort and positioning. This helmet is manufactured by Alpinestars and identified by manufacturer and vendor part number 8302225-110-YM.
