In-Mold Shell + Eps Liner

A polycarbonate shell is fused with an ESP cap directly in the mold to improve shock-resistance and lightness.

Roc Loc 5

This groundbreaking fit system provides unmatched comfort. Roc Loc 5 is nearly 40-percent lighter than its popular predecessor, Roc Loc 4. With Roc Loc 5, you can easily dial-in both fit tension and adjust vertical position with a single hand. Just twist the Micro Dial for a tighter feel on rough terrain, then back it off a notch and relax across the flats or a warm climb.

Polycarbonate

High impact resistant. Stain and odour resistancy, while withstanding sub-freezing temperatures. Dishwasher safe, but should be kept away from heating element.

Acu Dial

Combines single handed adjustment with a full fit band for a quick sure fit. Easy to master and ponytail compatible.

Super Fit™ Engineering

Giro's proprietary Super Fit™ sizing system is based on "human scale factors" data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human body s form, our Super Fit™ sizes comfortably and securely fit riders, and feel like they are custom made just for you.
