Review on U.S. Polo Assn. Interlock Engine by Noel Pilla

I ordered two of these, one in dark blue and the other in dark grey. Both shirts are interlock, so the same US polo shirt. However, navy blue is 100% cotton and significantly less grey. Also, the gray shirt is a 60/40 cotton blend and really does run a bit larger than most of my other shirts. It makes absolutely no sense for US Polo to do something like that. I can't blame Revain as the labels on the shirts have the same product ID, I think it's just an unfortunate choice of US polo design. I have no idea what the other colors are made of, I can only comment on the two I bought. See photos for more information.
