The Giro Tremor Helmet in Matt Blue Green brings adult-level trail technology scaled down specifically for growing cyclists. Engineered with Giro’s lightweight In-Mold construction, it fuses a polycarbonate outer shell directly to an impact-absorbing EPS liner. This creates a durable yet lightweight headpiece that withstands everyday trail adventures without straining young neck muscles.
Equipped with 18 generous vents, the Tremor keeps kids cool and comfortable during afternoon rides or pump-track sessions. The striking Matt Blue Green colourway provides high visibility and playful outdoor style, while the removable visor shields young eyes from glare, sun, and trail debris.
Achieving a precise fit is simple with the Roc Loc Sport dial fit system, which offers a 7 cm adjustment range for easy one-handed tuning. Paired with Giro’s Universal Child sizing, it adapts seamlessly across growth spurts for seasons of reliable protection.
Two-piece In-Mold polycarbonate shell fused with an impact-dissipating EPS liner for enhanced durability without extra bulk.

18 channelled ventilation openings to maximize cooling airflow during warm sessions.

Before buckling the chin strap, adjust the rear Roc Loc Sport dial until the helmet rests snugly and level across your child's head. The front edge should sit roughly two fingers above their eyebrows for optimal forehead protection, and you should be able to fit two fingers flat between the chin and the strap.
