AIOs, or All In Ones

 
Example:  Motherease All-In-One

• Usually cover, nappy and liner all together
• They have a fleece, or fleece and PUL or PUL outer usually, and the absorbent material and then the liner
• Nice and easy to use and often trim, but they can be expensive and can take a long time to dry when washing
• They may also lack versatility – of adding extra layers, different types of liners or different covers
