- Roc Loc 5 Fit System - The industry benchmark in comfort, stability, adjustability and weight savings. In addition to enhancing the fit and comfort of helmets, Roc Loc 5 allows you to easily custom tune the fit tension and the fore-aft tilt of the helmet in seconds using a single hand.

- 25 Wind Tunnel vents with internal channeling - Giro helmets are developed utilizing proprietary Wind Tunnel ventilation system.

It's the most effective cooling system available, and a difference you can feel every time you ride.
