Purchased in the winter of 2024 and worn for two seasons. Made of warm, fleece-lined material. I believe there are no noticeable stains, but I apologize if I missed any. I will fold it up small for shipping. Please refrain from purchasing if you are overly concerned about minor details. *This is a product from overseas, so there may be loose threads. *My 3-year-old son is 93cm tall and slender, but it felt small on him. Therefore, I think it would be too small for a 4-year-old.
