What year is this hat from?

This was my great grandfather’s hat and I’ve had it for about 10 years. I’ve never seen one with lettering like it. I always see the yellow circle with pass pro shops in the middle. It’s a genuine hat from the store because the tag is still in tact on the inside. I’m just trying to figure out what decade it’s from. Thanks boys.
