The San Francisco 49ers have officially unveiled the first alternate uniforms in team history.



San Francisco unveiled the alternate uniforms during the 2015 NFL draft, putting out a video to help show off the new duds:

The team recently announced they would give fans a sneak peek at their new alternate jerseys for the 2015-16 season on their Snapchat before the big unveiling at their draft day party Thursday night.

The jerseys, according to Comcast Sports Net's Matt Maiocco, are "player-driven" and look like Colin Kaepernick's practice jersey. These are the first alternate jerseys in team history and, per 49ers.com, were "the result of a coordinated effort between the 49ers, their players, Nike and the NFL."
