To keep his VERY long, blonde hair under control while he fights.
He always wears his hat because it's awesome, but took it off a few times. :)

Finn's hat is sort of a bear skin, I read in the adventure time wiki and set on the character and clicked Finn it said it is a bear

Finn takes his hat off in "To Cut A Woman's Hair" (season 2, episode 10)
You can wear any hat.

He has blonde hair.
