These are Leica-like corduroy slacks. They use a rayon yarn. I am selling them because they no longer fit. The quality is good, so it's a bargain if the size fits. Measurements (cm, laid flat) Waist: 41 Inseam: 79.5 Leg opening: 22 Please allow for some error. Color: Navy pattern Season: Winter Condition: I bought these a long time ago, tried them on, and then stored them in a drawer for a long time. They are in beautiful condition. They are a wide type and can be worn loosely, and the fabric has a cool feel. I don't remember the purchase price, but I think the quality is good.
