SRD:Monk's Belt

Belt, Monk’s: This simple rope belt, when wrapped around a character’s waist, confers great ability in unarmed combat. The wearer’s AC and unarmed damage is treated as a monk of five levels higher. If donned by a character with the Stunning Fist feat, the belt lets her make one additional stunning attack per day. If the character is not a monk, she gains the AC and unarmed damage of a 5th-level monk. This AC bonus functions just like the monk’s AC bonus.
