Mary and I have been wearing the Nolan Modular helmets for around 10 years now. They fit well, and they use the ratchet instead of D-rings, so are really easy on and off. We like them because they use metal latches for the modular part, instead of plastic. Good venting, internal tinted visor.
We've gotten them from Dennis Kirk. They have a no hassle exchange on helmets, so you if you don't order the right size, it is easy to swap it out until you find the right size.
I think the ones we have now are the N102's.
