helped the reflection of the sun off the turf, meaning there was less stress on a player’s eyes." It wasn't until 1990 that a team made this change, with the Cincinnati Reds changing their under-visor color to gray. The team wound up popularizing the gray under-visor because they won the World Series the same season they made the change. By 1995, all MLB teams were using gray fabric on their under-visors. Beginning in the late 1990s, teams began to experiment with black fabric under the visors to help with the sun's glare, and black sweatbands to make them appear less sweat-stained and by 2007, black under-visor fabric became the norm along with black sweatbands. In 2016, the New Era flag logo was added to the bottom left side of the cap. There are two styles of the 59FIFTY: the original, which has a flat visor and a tall profile, and the low-profile, which has a pre-curved visor and a rounded profile. Earlier versions of the 59FIFTY were made with 100% wool but eventually switched to polyester, which includes sweat-wicking fabric and sun protection. 59FIFTYs are fitted and do not have an adjustment strap like many other designs, such as the snapback. In 1992, the MLB logo was added to the back of every cap and in 1996, the World Series logo was added to the right side of the hat. Commemorative and special edition side patches appear on some caps and are also sold separately As of 2017, the caps were still being made partially by hand. Cultural impact Collaborators include BTS, Fear of God, Takashi Murakami, Marc Jacobs, MTV, and Chance the Rapper. New Era recognizes May 9 as 59FIFTY day. Fashion In the 1980s and 1990s, the hip-hop community began wearing the 59FIFTY as a fashion statement. Jay-Z, Eazy-E, Dr. Dre, Beastie Boys, and Aaliyah were among those who popularized it. New Era's CEO credits Spike Lee with bringing the 59FIFTY into the fashion world, which later fed into streetwear. Part of why the cap became a fashion icon is because it represented pride in one's city. The cap is also called Brooklyn style due to New Era's connection to New York and the borough's hip-hop scene. Leaving the gold size sticker on the visor became a fashion trend, enough that New Era added that they do not offer replacement stickers to the FAQ on their website. In
