Roc Loc 5, the newest retention system from Giro, makes adjusting fit tension and vertical position easier and more comfortable than ever; loosen/tighten with a simple twist. Wind Tunnel(TM) ventilation with 5 active vents and internal exhaust channels thrust cool, fresh air over and around the head, while forcing out heat and stale air.
