Nike navy vinyl pants with a warm, double-layered interior. They have elastic cuffs. My son wore these during breaks at soccer games. They are a kids' M size. They are labeled for heights of 140-150cm. They were only worn for a short period during the cold season, so they are in very good condition. There are also photos of the inside. The material may be difficult to see, but it is warm. - Brand: Nike - Color: Navy - Design: Logo - Features: Elastic waist - Features: Elastic cuffs Thank you for looking.
