One more opinion on the C3: I LOVE IT!
I had Shoei helmets for years but they always gave me a "hot spot" in the middle of my forehead.
Switched to a Schuberth C2 which fit perfectly, but was kind of a hassle to use with the latch on the side.
Got a C3 which fixes everything that was wrong with the C2. Easy to open and close, bigger sun shade, feels lighter and smaller, PERFECT!
