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 Small helmet features a thermo-injected shell made from an advanced impact-resistant thermoplastic polymer blend. Varying shell thicknesses help balance protection and weight, while the multiple-density inner liner places the appropriate density in key areas for effective impact absorption.
The Alpinestars Youth SM3 uses engineered inner and outer surfaces to help minimize the effects of oblique impacts. A low-friction coating on the primary EPS liner creates a slip-plane effect intended to reduce rotational acceleration forces during certain angled impacts. The visor release system is calibrated to release at a predetermined force, helping reduce loads transferred to the rider’s neck during an impact. Ten intake vents and seven exhaust ports promote airflow and heat exchange, while the visor directs air toward the ventilation channels.
Comfort and usability are built into the SM3 design. The crown and cheek pads can be replaced with optional thicknesses to tailor the fit, and the recycled-material comfort liner helps reduce environmental impact. Integrated hydration tube channels in the cheek pads support convenient hydration system routing. A soft 1-inch chin strap, stainless steel D-rings, and a secure retention system help maintain a stable fit. The Emergency Release System and removable cheek pads allow safer, easier helmet removal by trained personnel while the helmet remains on the rider. The Alpinestars Youth SM3 Fray Helmet is finished in Gloss Black/Orange/Yellow Fluo and is supplied in Small size under manufacturer and vendor part number 8301625-1455-YS.
