New Era's 59FIFTY hat needs no introduction. Even if you didn't recognize it as the official, on-field hat of Major League Baseball, you'll probably see at least one 59FIFTY during the course of your daily life, every single day. That's not up for debate, what is though, is whether to leave the sticker on under the brim or not.
