Let It RipKids these days. They love to ride, sometimes fearlessly, and they have more trails, bike parks and fun places to shred. We designed the Sidetrack to keep up with them. Styled after the adult Stoker mountain bike helmet, it does double duty by looking super cool and adding coverage lower on the head than traditional kids helmets. This model offers the option of MIPS (Multi- Directional Impact Protection System), which can give an additional measure of protection in certain impacts. It has extended coverage in the rear, our easy-to-use ErgoDial Fit System, and a visor to complete the look.Key Features:ErgoDial Fit System,In-Mold Polycarbonate Shell,PinchGuard Buckle,Snap-In Visor,Weight: 276 Grams,Vents: 15,Certification: CE EN1078 CPSC Bicycle.
