Howdy, saw this link on another site, looked interesting so I had a quick read. It's not 1 April so I figure it's legitimate, ha ha.
I use an open face on the HD but a full face on the other bike, while my mirrors work fine for me, there are those out the who may find this useful.
I'm not sure if it's an Aussie invention, but if it is, way to go!!!!
Anyway have a look here, ReeVu helmet.
Cheers and beers,

I'm waiting for the Skully P1 helmet to be released in this country, 10 times more fun.....
