FEATURES:

Replacement rear vent for Arai Defiant Helmets

The ACR-4 flow thru exhaust vent allows airflow to pass over and through the vent, accelerating exhaust flow from helmet interior when open, and reducing drag when closed

Ventilation and aerodynamics are designed to work together to allow more air flow, while reducing drag
