Karate uniforms, known as gi, are traditional outfits worn by practitioners of karate. They typically consist of a loose-fitting jacket and pants made from durable cotton or a cotton-blend fabric. The uniform is designed to allow for freedom of movement during training and competitions. The gi usually comes in white, although other colors may be used to signify rank or style. A colored belt, called a obi, is worn around the waist to indicate the practitioner's level of skill. Proper care and maintenance of the gi are important to ensure its longevity and appearance.
