The size is free size. For someone with a build of 175cm in height, 65kg in weight, and a muscular physique, the trainer fits just right or is slightly loose. There is a feeling of use, pilling, and loose threads due to aging, but it can still be used actively for everyday wear. Please check the photos for small stains and scratches.
