Similar to an all-in-one diaper, pocket diapers consist of a waterproof outer cover and a soft inner layer. The difference is that the absorbent layer is not sewn into the diaper, but inserted into a pocket between the inner and outer layers. These inserts can be anything from a prefold or washcloth to inserts designed specifically for the diaper, and are available in differing levels of absorbency.

Pocket diapers are very flexible! Many people use them at night, because you can use a more absorbent insert for heavy wetters.
