The measurements shown here pertain to unprinted jerseys. All performance jerseys/materials experience some shrinkage during the screen printing process due to the high heat they are exposed to. An acceptable rate of shrinkage is 3-7%, which is what we generally see when we print our garments. Please take this into consideration, as well as the notes above, when you are figuring out your jersey size. Please note that dark/coloured jerseys will absorb more heat in the screen printing process than light/white jerseys. For example, you may find that your white jerseys are 1-1.5” longer than your black jerseys if you have a lot of screen printing done. This does fit within the above 3-7% acceptable shrinkage rate.
