I just wonder how is the sizing of the Nike Boys Clothes. I wear size M of the Nike Men's Apparel. Would size XL of the Boys Apparel be the same as a size M of the Men's Apparel?? Or would a size XL be smaller.... Because when it is the same as an M, it would be possible to buy boys clothing which are cheaper than men's clothing And i read sometime at E b a y in an advertisement that there was sold an L or XL boys, which would also fit an S or M men. Hope someone knows if something like this is true and if it's true, where size XL of boys corresponds with at the Men's Apparel.
