The Defender Demister is an amazing product that fits most Defenders, wide vent versions from approximately 1983 onwards.
Fitted in about 30 seconds using a couple of screws, no drilling or complicated processes. All you need to fit them is a screwdriver!
It works by controlling the existing air flow, distributing it to the areas that need it most... your front and side windows.
Safety for both yourself and anybody travelling in your vehicle is the most important consideration for any driver. The Defender Demister ensures that both side windows are mist and condensation free thus ensuring visibility even in the worst weather conditions.
