Kabuto Kamui Fluente. It's their sport-touring hat and everything about it is excellent. I am a neutral to slightly round head with a pretty square face and the fit is pretty much perfect. Graphics, ventilation, aerodynamics are also. It has a drop down sun screen that works just fine. Weight is good and it uses a ratchet fastener rather than D rings, which I like a lot better. You might have trouble finding a dealer that has them on hand but you can always email the distributor (Western Power Sports) and ask if they can point you to someone.
