If you wanna' wear what the players wear, this is the Brew Crew's 2018 pre-game Authentic onfield batting practice trainer jersey, made of 100% lightweight polyester with 3/4 sleeves down just past the elbows and a quarter-zip collar along with the fully embroidered vintage team logo on the left chest. This thing is SICK ... if it was my size i would just keep it to wear myself!
