I have a helmet that was cheap, but comfortable. It's a Bell. However, I noticed on last weeks ride that it's H O T! Temps have started to creep up here in Houston, so I'm considering investing in a better vented helmet.

The first one I've looked at was the Giro Aeon. Anyone else have any suggestions for well vented helmets?

Also, this may sound silly, but I was wondering if anyone has problems with their scalp getting sunburned with a well vented helmet and how to prevent that. My skin is pretty sensitive and as a general rule I have to make sure I'm well lathered in sunscreen.
