Fake jerseys are incredibly easy to spot in a crowd full of authentics.
All your doing is giving profits to copycats (who reside in China), instead of Nike/Seahawks/NFL (USA).
What have they done to deserve your money? Nothing, except copy the work of others. You support that?
Also, a bunch of children's Halloween costumes from china were just tested for dangerous levels of toxic substances. And those were legitimate products. You think these factories churning out these fakes are going to care when they have no one to answer to?
