I allways find it strange when people try to get Light Armoured feat on their casters ...
I mean just by casting Mage Armor, you get the same ... often even better AC ... while you keep robes that usualy actualy benefits casters ... O_o
And even if you dont wish to take Mage Armor yourself, you can either cast it from scroll (and there is lots of those around) ... or simply use Gale to buff you and then switch him out of your party.
