What would be the reverse Reverse Flash 9Fifty Hat? Would that be a fitted, regular Flash hat with a curved bill? I only say that because the Reverse Flash 9Fifty Hat is a one size fits most hat with a flatbill and the classic Reverse Flash logo! I guess this game would get pretty crazy on opposite day, so we'll just cut this short now and let you know that the 95% polyester 5% spandex Reverse Flash 9Fifty Hat was made by New Era. They are all sorts of fancy!
