Anyone wear a Carbon Fiber helmet?

[The Bad Man's Angel]

I'm looking at one of the Advanced Carbon Composites carbon fiber half helmets. DOT helmets have only have 5/8" of padding as compared to 1" or more for all others i've seen.
Any body have or use one of these?

I have and sometimes even use one of their extended half helmets. Nicely made and very light.

Yes, I have a Harley-Davidson carbon fiber half shell. I like it so much I haven't even wore (on a ride) a 3/4 HD helmet that I bought at the same time.
