Cloth A-Z

We have tried to collect all the acronyms and unfamiliar words that you may hear in the cloth nappy community to help you make sense of them :).

All grouped in alphabetical order to keep it easy to search:


AIO - All-in-one nappy, where the waterproof outer shell is sewn together with the absorbent insert(s), either fully on both ends, or on one side. This makes an easy to use cloth nappy, which resembles disposables the most. These nappies come in different sizes, and can be velcro or snap closing.

AI2 - All in two nappies, it is also called two parter nappy, where the insert and the cover is separate, but most often they can be snapped together to keep the insert(s) in place. Sometimes velcro is used to keep inserts in place, but it is more often used in the Eu. The all in 2 nappy covers (shells) are not lined, which makes them easy to keep clean, and can be reused 3-4x before they get soiled. Just wipe off moisture from the inside, and as long as the leg elastics are not wet, they can go back on the bum. Most often AI2 nappy covers are lined, so they are most often called Hybrids, but still belong to the AI2 category.

AWJ - Athletic Wicking Jersey, it is a lining material used in modern cloth nappies to keep babies bum dry, and to drive moisture away from the bum. It feels cool to the touch, even when wet.
