ProForce Gladiator 7oz Team Karate Gi / Uniform Made of 55% cotton and 45% polyester fabric, the uniform is accented with Black, Red and Silver. The pants have a curved side line breaking away from the straight side stripes. The V-Neck top has been tailored so that it is no longer necessary to wear a t-shirt underneath in order to keep covered. Under the back center of the jacket lie two mesh vented slits for improved air flow and added comfort.
