Fitted diapers are held snug by elasticized waist and legs and secured by hook-and-loop (Velcro) or snaps. They consist of absorbent material covered with a soft layer (often microfleece) that touches the skin. Fitted diapers are not waterproof; these diapers require a separate waterproof cover. Because fitted diapers are made in specific sizes, a baby might require two or more sizes of fitted diapers over the course of diapering.

Fitted diapers are another great addition to have on hand. They are particularly useful for infants at nights or with other caregivers, as well as providing extra absorbency at night and naps for older babies or heavy wetters.
