'47 Unisex Mlb New York Yankees Clean Up Baseball Cap

Is this hat an adult size or youth size?

What color is the atlanta brave cap and the boston red sox cap?

I have a pretty big head. Does anyone know the size range on the adjustable band?

I'm seeing a lot of conflicting information about the color of the atlanta braves cap. is it a faded black/gray color like in the picture? or navy?
