I bought the Schubert C3Pro because I had never worn a full face helmet when I used to ride 30 years ago and when I got back into it with a R3R, all I had to do was "Google Veiw" all the pictures of messed up faces, heads, and helmets to decide. I thought the Modular design would be a good compromise and I wanted the best regardless what it cost. It didn't make sense to me to ride a bike worth 12,000 dollars and then go cheap on protection. I'm also an ATGATT convert with full Motoport suit.
Thought I would warn you that Shubert's are known for their ovaloid shape vs others. I have that shape so the helmet fits me perfectly but I wouldn't buy one again for a couple of reasons. It is hot and loud in my opinion! I actually took it apart and put that sound deadening Dynamat in the ear cups and drilled out the supposed vent channels in the styrofoam to try to get more cooling. Only helped a little? But being modular allows you to open it, like in stop and go city traffic and it's comfortable, or with just the visor up isn't bad. In retrospect I think I was seduced by their excellent advertising and wanted to believe I could have it all. Their fancy graphics and videos of the wind tunnel make you believe it will be cool and quite at the same time. Another annoyance is the quick release chin strap they boast. I can't stand it. It's a great idea, like on a ski boot, but the placement is such that it digs right under my left jaw bone and the strap isn't adjustable. I had to make a separate leather pad to cushion it.
All that being said, I am glad I bought it because I have learned to live with the heat and will never go back to open face. I will, however, try a different brand and more than likely forget about the modular idea.
