PUL
Polyester Urethane Laminate = PUL is fabric with a waterproof laminate applied to the back.  It is the waterproof layer in the majority of styles of reusable diapers.
This makes for an extremely thin, soft fabric that is waterproof and easy to care for.

AIO - All-In-One - AIOs are fitted diapers that have a waterproof outer layer. This layer usually consists of fabric that has a PUL (PolyUrethane Laminate) backing, polar fleece such as Windpro, or wool. These are the closest in similarity to disposable diapers since they are a one-piece diapering system. The absorbent soaker material is often sewn into the diaper; it may also be detachable.

AI2 - All-In-Two - AI2s are very similar to AIOs with the exception that the absorbent soaker material is not attached to the diaper in any way. The soaker is usually a second, separate piece that must be used in conjunction with the diaper. The drying time for these diapers is shorter than the traditional AIO.

Diaper Covers - Covers come in many styles and shapes, but their function is to provide a waterproof outer layer for non-waterproof diapers (all except AIOs). They are often fitted with elastic and fasten with snaps or Velcro. Some covers pull-up, like underpants. Diaper covers are usually made from polyester, Polyurethane laminates (PUL), waterproof nylon, fleece or wool.
