New Poly MLB Caps Fitting the Bill

Major League Baseball and New Era have introduced its first significant change to player hats in 50 years. Wool is out and polyester is in, apparently with a built-in "vapor management system" to better "wisk" away perspiration from players' sweaty brows (as if they sweat), help combat glare, and keep the players from, well, stinking. Over the course of a 162-game season, sweaty wool can start to become a little offensive, especially when it rains. The 59FIFTY (100% polyester) is the style being used by players in games, while the 39THIRTY, a 60/40 poly/wool blend currently being worn by players at spring training, is used exclusively for batting practice. Still no word on if MLB will adopt breathable cotton as their uniform fabric of choice -- something first introduce by George Costanza on Seinfeld.
