Oakland A's Terry Cloth Lined 1980's Pinstriped Visor / Hat

This vintage pinstriped twill hat features A's logo embroidered on front, comfy terry cloth lining inside, sturdy bill, and an adjustable buckle in back.

My guess is that this was some promotional giveaway back in the 80's for a home Oakland game. Overall in really nice shape especially for being over 30 years old
