KP BOY baby vest. Size: 70-80 Worn for one season last year. There are buttons on both sides, making it easy to put on and take off even for newborns or before they can hold their heads up. It's a slightly thick fleece, and I think it will be useful both indoors and under a coat. For keeping babies warm. Material: Body: 100% polyester Neckline: 38% cotton, 35% polyester, 25% rayon, 2% polyurethane
