we talking NFL football or what?

in my experience NFL jerseys run large. i wear large t shirts, and a large NFL jersey is plenty big enough for me to wear a t shirt under it.

yes NFL football.. forgot there were many brits on here.

yeah, im from america, so when i hear football i normally think NFL first. just wanted to make sure thats what you wanted. so yeah, in my experience they run big, so if you get a large you should have no problem wearing a t shirt under it.
