This comfy zipper footie rompers is perfect for your little dreamer. Features YKK zippers for quick wardrobe changes. It is a perfect staple piece for your baby, infant, or newborn. We blended the already super soft and comfy azlon from soy fiber with organic cotton to make this piece extra special. Azlon from soy is a recycled material made from the left over pulp of soy milk production. Its porous structure allows extra air permeability to keep babies warm in the cooler days and dry during summer time. Combining azlon from soy and organic cotton gives this piece the finest comfy touch.
