I have GT Air, love it, nice and comfy and guess what, you put it on and suddenly ...... there is silence! That helmet us super silent! Visor does not fog up ever, even if you try to get it fogged - it will not fog up! The only thing which I did not like is that field of vision on it is kindof more for straight sitting position rather than leaning forward. Helmet is awesome overal, I'm using it when riding my supermoto berg and cb1000r but when on superbike, it restricts me from looking up/straight when leaning forward/hiding behind the screen. That's the only negative thing about it but maybe that's just me being fat lol. Before you buy, get it on your head and sit on the bike and try hide behind the fairing looking straight.
