The Alpinestars Youth SM3 Fray Helmet is designed for young off-road riders who need dependable impact protection, low weight, and a secure, comfortable fit. This Medium helmet features a gloss red, yellow fluo, and black finish, along with a thermo-injected shell made from an 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.
The inner and outer helmet surfaces are engineered to help reduce the effects of oblique impacts. A low-friction coating on the main EPS liner creates a slip plane designed to help reduce rotational acceleration forces during certain angled impacts. Ten intake vents and seven exhaust ports maximize airflow and heat exchange, while the visor directs air into the ventilation system. The visor release system is calibrated to release at a predetermined force, helping reduce forces transferred to the rider’s neck during an impact.
Fit can be customized with replaceable crown and cheek pads available in different thicknesses. The comfort liner uses recycled materials, and integrated hydration tube channels in the cheek pads support convenient hydration system routing. A soft 25 mm chin strap, stainless steel D-rings, 3D-contoured cheek pad foam, and an Emergency Release System help provide a secure and comfortable fit. The removable cheek pads allow safer, easier helmet removal while the helmet remains in place. The Alpinestars Youth SM3 Helmet is intended for youth riders and is identified by manufacturer and vendor part number 8301625-3051-YM.
