[QUOTE=Sutherngintelmen;15450904]Hope the c3 has it too.
The shield's different, according to Schuberth USA. Instead of pushing forward on either side, the C3 shield has a small gap when lowered but not latched down. This is the City position, allowing a little air flow. Push it all the way down=sealed.
Haven't seen any mention of how it works in real life.
