Warm 80-size outerwear made of polyester material. - Size: 80 - Material: Outer fabric: 100% polyester, Filling: 100% polyester, Hem: 96% polyester, 4% polyurethane Thank you for viewing. I bought this about 4 years ago, but I've only worn it a few times. It's size 80, but I feel it runs small. This MA-1 jacket is so cute for babies! ^_^ Only those who understand that this has been stored at home, please. I plan to compress it to reduce the thickness when shipping.
