We had brought to you the Birmingham home kit 11/12, Birmingham away shirt 2011-12 and Birmingham third kit 2011-2012, made by Xtep when they were released by the club. However they were released without a strip sponsor and now Birmingham have confirmed Rational FX as their new kit sponsors.

Fans now have the option to buy the new Birmingham strips with or without the sponsors logo. London based Rational FX initially thought about sponsoring the kits on a match by match basis, but then agreed to do a one year deal with the Blues.

Here are the new Rational FX sponsored Birmingham kits 11/12 ( home and away)
