Im looking at getting a Nolan N84 and am after opinions form people who have one. I like the idea of being able to flip the 2nd tinted visor up or down as required however at the same time am wondering how effective or ineffective it actually is when out on the road. Ive seen some comments stating that the clear visor gets scratched because of the 2nd tinted visor is that true? If you have the Chin curtain on but arnt using the anti-fog insert do they have a tendancy to fog up? I havent been able to find many reviews so any opinions would be appreciated.
