The San Francisco 49ers will unveil new alternate throwback uniforms at tonight's State of the Franchise event. Players, however, have already seen the new duds.

The 49ers posted the following video featuring various players reacting to the new uniforms while viewing them for the first time.



"I can tell you we rolled them out to the team the other day, and the reactions were tremendous from the players," said 49ers president Al Guido on Tuesday during an interview with 95.7 The Game. "We're real fired up about it. I think our fans are going to love it. I don't want to go too much further on any other specifics because you might be able to guess what they are, but let's just say I think our fans are going to really appreciate the throwback nature of the jersey."
