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.
