What is the hat that Dr Neggi Korin "The Professor" wears?

TheProfessor:

The profile picture on your screen is of a rather dashing looking Kui-tan. He seems to be well dressed, and the fur on his face curiously styled. He’s also wearing a funny hat you think you’ve seen somewhere before...

Username: TheProfessor
Sex: Male
Age: 30 Years
Race: Kui-tan
Planet: Uveto
Bio: Lonely intellectual. Looking for somebody who can hold up a conversation. My interests include ancient cultures, dead languages, and dry whiskey.

Iv got the feeling he's wearing a fedora....but I really just can't tell ...

That would be my guess too I had him pegged by his description as the Kui-Tan version of Indiana Jones.
