sorta-hat

What's the deal with visors? 'I want to wear a baseball cap, but I'm not committed to a whole hat... hmmm... I'll just cut the top off.'
Georgia says that a hat will make your head hot, since you release heat through your head, and Joe chimed in that "your head is your chimney."
If you are that worried that a hat is going to heat you up that much, maybe go hat-less. Don't half-hat it. Thanks.
