Wind Deflectors are also referred to as Rain Guards due to their rain repelling characteristics. In-channel wind deflectors, unlike exterior mounted, are fitted into the window channels of the car doors. Both variations enable you to keep your window open while still protecting the interior from rain. In rainy weather, condensated windows can be problematic, preventing clear vision from inside the cabin. As deflectors allow natural air to circulate in the car, this prevents the risk of foggy windows during rainfall.
