To use this gi, simply put on the jacket and pants like you would any other martial arts uniform. When you're training, the breathable cotton will keep you cool and comfortable. As for care, it's best to machine wash it in cold water with a mild detergent. Avoid using bleach as it can damage the fabric. Hang it to dry to maintain its shape. Be careful not to snag the fabric on sharp objects during training to keep the double - reinforced knee padding intact.
