Fitted diapers are some of the most absorbant and easy to use cloth diapers. They come in a variety of fabrics and will have snaps or velcro. They are great for newborns, because they can be adjusted to fit perfectly. They are also a favorite for parents of heavy wetters.
Regular Fitted diapers are not waterproof as the outer layer is a natural fabric. These will need a diaper cover.
Hybrid Fitteds have a layer of waterproof PUL fabric and will not require a cover.
