Giro: Big Kid Style The Scamp II is Giro's smallest helmet designed for young (or future) riders but it still goes big with features and style. Taking design cues from adult helmets like Manifest Spherical, this lightweight in-mold helmet features impact-dissipating EPS foam with a sturdy polycarbonate shell, plus 13 vents for efficient cooling power. The Roc Loc® Junior fit system provides extra adjustability with a simple-to-use dial for several years of head protection for fast-growing rippers. The XS is designed for riders aged 1 and older while the Small is for riders aged 5 and older. Whether they're rolling along in a trailer or powering the pedals themselves, Scamp II is going to make kids want more bike time. IN-MOLD CONSTRUCTION — In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.ROC LOC® JR. FIT SYSTEM — Roc Loc® Jr. is a simple, durable, dial fit system specifically shaped to match the curvature of a child's head. The shape was developed with years of research into anatomic data to ensure a secure, comfortable fit. A large, rubberized knob makes it easy for adults to adjust the helmet for proper tension, allowing kids to quickly start their ride.  SPECIFICATIONSShell TypePolycarbonate shellImpact Liner TypeEPSVentilation Type13 vents and internal channelingConstructionIn-Mold polycarbonate shell with EPS linerFit SystemRoc Loc® Jr.VisorQuick Link removable visorReflectivityReflective rear decals
