Giro Helios Eclipse Fit System

This is a Roc Loc 5 Air replacement system for Giro Helios and Eclipse Spherical helmets. This revolutionary adjustment system adds a new dimension to helmet performance by improving cooling and enhancing fit, comfort, and stability. By using a patented design that suspends the helmet slightly above the head, Roc Loc 5 Air allows for a cool airflow directly over your head, further enhancing the performance of the internal vents and the channels that dissipate heat from the helmet. The fit and feel adjustments mimic the Roc Loc 4, allowing you to easily adjust the fit tension and the forward-backward tilt of the helmet in seconds with just one hand.
