I bought a knock off and it was a total waste. Like, seriously disappointing. I ended up just giving it to someone so they had something Nationals related to wear to a game. I have my game worn BP jersey that I got for a good deal ($50) because the player was traded. I was more into it because of we share the same last name, not because I'm a JC Romero fan. I finally sprung for the big ticket authentic Harper jersey and I'm glad I did because it is (much like myself) a sexy piece of gear, but I don't think I'm gonna be dropping $250 for a jersey again anytime soon.
The one thing I noticed while I was at a game one time is that the patches on a knock off one faded really bad. One guy was wearing on which the left shoulder patch had faded to a bright orange.
