Nike lightweight pants. The size is listed as XS, but since it was purchased overseas, it can fit up to a small/medium. If you are tall, the length might be a little short. The waist is elastic and comfortable to wear. There is some wear, but I don't see any stains or damage, so I think it can still be worn. In the coming cold season, you can wear them underneath as a layer. There are no pets or smokers in the family. Thank you.
