Appaman Vest is part of Estellas unique collection of boys and girls outerwear. Imported, these kids vests are made of nylon and down and they are soft and fit great. Like all our boys and girls vests these Appaman vests run a little small so if for example the child is 3 months old, we recommend that you purchase the 3 6 months size, NOT the 0 3 months size. Feel free to email or call us if you have any questions.
