How come all Tennis hats are adjustable and not fitted (or at least Flex-Fit so they fit more than just one size)? I am not a fan of adjustable hats and only wear fitted hats, and it's really hard to find a good hat for tennis that's not too hot or heavy. Been wearing the Nike Golf hat with the mesh back lately and that thing is really light and cool with the mesh. Any idea why no fitted hats for tennis? I normally only wear Nike hats, but curious about any other brands that might have a fitted tennis hat that I've overlooked.
