AD2019 Color: Black Material: 100% Polyester Size: XS These are standard pants that are released every season in various materials. Made of stain-resistant and durable polyester. They have an elastic waistband for easy wear, and although they are size XS, my husband, who is 173cm tall and slim, and I shared them, so they are suitable for men as well. They can be worn throughout the year, except in midsummer. Please understand that the knees are worn and there is a tear on the left knee before purchasing, as I wore them often. I think they can be repaired nicely if you take them to an atelier.
