Contour diapers are like Fitteds in that they are just the absorbent part of the diaper and are already cut to the shape of your baby. They are different in that they do not have elastic anywhere in the diaper.
Pros: cheaper than fitteds, easy to use, natural fibers
Cons: requires separate cover, requires cover or fasteners to hold in place, because they do not have elastic there may be more poo which gets onto the cover
