The Versa-Vent windshield also features a defog mode. No other windshield offers all these features. The vent is made of glass filled nylon, so it’s incredibly durable. The scoop on the front gathers up air off the hood and re-directs it to inside the vehicle so even at very slow speeds there is a surprising amount of air that can come through the vent. The design of the scoop and the gasket between it and the windshield keeps precipitation out while still allowing airflow in—as much or as little as either the driver or passenger desires.
