The Libra Cloth is one of the 12 Gold Cloths worn by the most powerful of Athena's Saints. Covering the most of the body, they have the most resistance to damage and freezes at -273.15 degress, the Absolute Zero according to Camus.
Since Shiryu is the student of Dohko, he is allowed the use of the Libra Gold Cloth when he has need for it. The Cloth covers most of his body, fully covering his chest, arms and legs.
While wearing this Cloth, the Libra Saint has a golden aura when he burns his Cosmo. It covers most of the wearer's body, with several of the Libra weapons visible on the Cloth. A large waist covers the lower parts of his body, although the Libra Saint often does not wear the helmet.
