The Karate Gi is a traditional martial artist's uniform made of white cloth. The top is held closed by a black belt tied around the waist, and the cuffs of the pants are slightly ragged and worn. Matt's version of the Karate Gi appears to have a black and white symbol on the right side, just under the belt.
The Karate Gi mainly boosts the wearer's HP and Evade, with smaller boosts to Defense and Magic Defense. It also raises the wearer's resistance to Earth, Dark, and Tired, and boosts their Evade further if they're hit by a powerful attack.
