jersey's with the numbers sewn in are real and jersey's with the numbers printed on are fake

The ones that are printed will probobly stay on longer.

If they are sewed on they will fall out but if they are printed on they will last a lot longer

if the number are sewn on they are tougher and are authentic, if they are printed on they will eventually rub or peel off and are replica jerseys

The jerseys with the numbers, names, and any logos on the jersey sewn on are authentic jerseys they are what they wear on the field. Authentic jerseys also have triple knit and the stripes are a part of the fabric.

Jerseys with numbers, names, and any logos on the jersey are printed on are called replicas. They are not FAKE they are still authorized by the NFL.

There are also jerseys with everything sewn on but the the stripes are printed on they are called Replithentic jerseys.

All of them are authorized by the NFL and are not fake. The key when looking for an authorized jersey is the nfl shield on the collar at the neck and the reebok logo on the sleeve.

If the jersey doesn't have BOTH of those it is not authentic and in that case is FAKE, CRAP, CHEAP.

Authentics will last longer and are better in the wash.

Replicas can last a long time if you take good care of them and avoid washing them that much. Do not wash them if there isn't visible dirt on them.
