The Oakland Athletics have a unique color scheme of yellow and green. To be honest, we don't exactly love the colors for casual sports fans. When attending an A's game in Oakland, however, enough people are wearing the team colors so that they don't stand out as being so unfortunate.
If you're a fan that would like to show your pride for the A's without wearing the bright colors the team does at home check out some of the toned down options. The A's have a nice looking, blue and white Franchise crushed hat, here.
If you're into the on-the-field 5950 hats, check out the A's alternate cap. The A's also have one of the least offensive spring training or bp cap, found here.
Typically, I recommend sporting most MLB teams road grey jersey - which nearly always feature the city or the state of the team across the chest. Oakland's road jersey is the exception to this rule. I think it is just a bit plain and dull. Instead, we like the A's green alternate home threads.
For a more casual look representing the city of Oakland - check out this shirt.
Finally, the A's have a history filled with interesting personalities and players. If you've got the cash, a Rollie Fingers throwback jersey is a great choice.
A's fans sitting in the bleachers tend to be more hardcore - and if you're one of those fans, anything goes when attending a game, especially during the playoffs. On the other hand, if you're a more casual fan, take a look at some of the toned down options given the teams color schemes.
