Chin Vent Covers are designed around open cockpit drivers. Adhering to the helmet using double sided adhesive, the Chin Vent Covers restrict inbound airflow from the top chin vents, while still allowing hot air to vent out through the uncovered top portion of the Cover. Air flows through the lower uncovered vents and then exits directly through the upper partially covered chin vents, creating optical ventilation for open cockpit drivers.
