Gildan Shirt for Screen Printing

An adult small is slightly larger than we need in the 12500 Gildan 9.3 oz Pullover Hoodie. Could you advise how the sizes of the Gildan youth G185B hoodie compares to an adult small mentioned above? Looks like it comes in S thru XL, but I have no idea how this compares to a 12500 adult small. Ask us about our Customizing
