The Giro Tremor Helmet in Matt Blue brings big-trail performance to growing cyclists. Featuring Giro's advanced In-Mold construction, this helmet fuses a tough polycarbonate outer shell directly to an impact-dissipating EPS liner. This creates a lightweight yet exceptionally durable structure that withstands the daily bumps of youth riding without weighing down developing neck muscles.
Temperature regulation is seamless thanks to 18 channelled ventilation openings designed to channel fresh air across the head during warm afternoon rides or intense pump-track sessions. The clean Matt Blue finish delivers a modern, vibrant look that young riders will love wearing, complemented by a removable visor that guards eyes against sun glare and trail debris.
Achieving a secure fit is effortless with Giro’s Roc Loc Sport fit system, featuring an easy-turn dial with a 7 cm adjustment range for quick, one-handed adjustments. Combined with Universal Fit sizing, the Tremor adapts easily across growth spurts for multi-season head protection.

Before fastening the chin strap, turn 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 proper forehead coverage, and you should be able to fit two fingers flat between the chin and strap.
