Ok, instead of being lazy I called the pro shop. This whole thing is a cluster fuck. Talked to a very nice lady who explained it all to me so I'll try and break it down for everyone.
The online Bengals pro shop you get to from the Bengals.com webpage is no longer ran by the B&M pro shop. It's ran by fanatics not connection with the Bengals pro shop at all.
The color rush jersey's the only ones that you can buy are Dalton, Greene, and Eifert, so no Geno, Dunlap, or Byod.
The $79 ones are 100% cotton so the tshirt like ones.
The $149 ones are the jersey's with stitched letters and numbers. I think she's wrong about the numbers being stitched, however the description also says stitched.
