About Judo Uniforms
Judo uniforms are generally constructed out of 100% cotton, bleached white. Cotton is the best choice for breathability. Care should be taken when laundering, as most judo uniforms are not pre-shrunken and will shrink up to a full size from excess heat. Therefore, washing in cool water and air drying is highly recommended to avoid shrinkage.
