This armor acts as Studded Leather and as a Wizard Robe.  Wizard's can use it without any penalties.  The Wizard's Duster automatically has protection from fire, cold, lightning, and evil.  When hit, the duster absorbs all but 1 damage from the source.  The Wizard's Duster also acts as a Robe of Useful Items.   Also the wearer automatically gets a cursed called: "Badassdom".

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
