Thanks for the knowledge everyone. I plan on checking out a Bern helmet as I understand they have hefty sweatbands with or without a bill. I'm not worried about looks, heck I don't even worry about wearing a helmet, just figured since I wear a cap anyway....
As for the Bern models, they don't look like they'd keep your head cool very well so when I get to a retailer I'll check it close. Other than that, I'll just stick with my ruddy old cap.
