Before the onset of winter I was very keen on getting the mx version VX-24 but couldn't find a stockist locally. Even though they do a winter kit for it (at least in the USA/Canada) I opted for a cheaper-than-Arai-and-Shoei dual sport helmet (Airoh S4 - which has much greater peripheral vision than my Caberg Justissimo flip-up).
Come the spring/summer I may look again at the VX range - I hate ear plugs and being totally cut off from an important life/engine/mechanical saving sense (hearing!!!!) but the air fit system sounds like a great half way measure for noise reduction.
