there is no adidas authentic nba jersey size 42 or 50 like you see for sale on ebay so if you see these sizes the jersey you are looking at is counterfeit.also authentic adidas nba jerseys are not mesh they are a solid body with stretchy sides.so again if you see a mesh jersey with the seller claiming its a authentic on court jersey its counterfeit.
