Giro Helios/Eclipse Fit System Large BlackThe Giro Helios/Eclipse Fit System adds a new dimension to helmet performance by enhancing cooling, as well as fit, comfort, and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc 5 Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 4, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand. Only compatible with Giro Helios and Giro Eclipse Helmets.768686410826
