These are pants from 5351 Pour Les Hommes. The fabric is 41% wool, with other materials including polyester, nylon, and rayon. They are made of soft fabric and have a drawstring waist. There is also elastic, but it doesn't stretch much. I'm selling these on behalf of my brother, so I don't have all the details, but he's selling them because they no longer fit. Thank you. I have a cat. I will be careful when packaging, but there may be oversight. Please understand. Thank you.
