Umpire polo shirt used in youth baseball. Worn in games about 4-5 times. Navy, with a pocket on the left chest. Four-button. There is no size notation, but I think it was XXO. Even when wearing a chest protector for the umpire underneath, it's not too tight. *I am 170cm tall with a chest measurement of 100cm. - Color: Navy - Design: Polo shirt, striped collar - Country of Manufacture: Made in Japan - Material: Mesh material - Features: Excellent breathability, comfortable to wear Thank you for looking.
