I have one of the modular HJC (?) helmets and just love it. i wear glasses and it is very handy for that as well. I never had one like this before, but I will never buy anything else once I've had one. They are sweet and the way to go if you're going full faced. I also have a 3/4 helmet that I use mostly for opassengers, and Matt borrows it all the time, but I hardly wear that one myself.
