UNIQLO Baby Boa Fleece Vest - The outer side is a fluffy fleece material, and the inner surface and inside of the pockets are 100% cotton. - Plastic snap buttons are used to be considerate of metal allergies. Can be worn for a long time in spring, autumn, and winter. I wore it for a year when my child was 1 year old, and it has no scratches or stains, so I think it's in relatively good condition. Please understand that this is a used item before purchasing.
