I saw a bunch of Titleist hats on their web site. Local stores didn't seem to carry the wide variety.
Bought a few different styles online (which I hate doing - hard to find a proper fit)
Measured my head - was M/L fitted.
I Prefer more lightweight, breathable hats for GA summers
Grey = Tour Sports Mesh, fitted (fits a little big for me, is a bit heavier than I expected) 3rd best one
Black = StaDry (like the lightness, adjustable strap, but the crown is a bit wonky - a little higher on one side) 2nd best one
White = Tour Elite, fitted (a hair big for my head)best one
We'll see how they do after I sweat in them
