The Very Hungry Caterpillar Pattern 100cm Winter Pajamas My son wore these around the age of 2. Although they were worn frequently, they were washed and dried every time, so they are not worn out and are fluffy(^^) I think they are thick fleece. Although there are no stains or dirt, there is a feeling of wear. The top has a slightly stronger feeling of wear.
