This is a Majestic MLB umpire shirt, short-sleeved, for base umpires. Of course, it is an authentic Majestic product. It was supplied to MLB umpires, but it has been stored as deadstock due to a change in manufacturers. It is new and unworn, but please note that there are some creases from storage. The size is US XL, with a length of 84cm and a width of 69cm. Please allow for some error as these measurements are approximate. It is a US size, so it is a large fit. Although it is a base umpire shirt without a chest pocket, it can be worn as a home plate umpire shirt with an inside protector.
