I can not get over how many fake ripoff NFL Reebok jerseys are listed on E-Bay.  If you are unsure, just ask the seller if the attached tags have a round foil NFL hologram on it.  If it doesn't, I wouldn't touch it.  It is more than likely a cheap piece of junk.  All licensed NFL clothing from Reebok has the NFL foil hologram, about 3/4",  on the tags.  Everything else is just a crappy ripoff.  Why would you pay anything for a counterfeit jersey.  Probably fall apart after one wash.
