These are Uniqlo fleece-lined pants. The outer material is nylon, and the inside is warm. They were very useful in the winter. I'm selling them because my child has outgrown them. There are no noticeable stains or scratches, but please understand that these are used items before purchasing. Uniqlo pants 140 Uniqlo cargo pants fleece-lined 140 UNIQLO 140 pants UNIQLO cargo pants
