Cloth Diaper Terminology
Cloth diaper lingo can get a little confusing! Here are some definitions for you:
AIO ( All-In-One)
AIOs are essentially a fitted diaper and a cover sewn together. The outer layer consists of fabric that has a waterproof backing. These are similar to a disposable diaper since they are often a one-piece diapering system. The absorbent soaker material is often sewn into the diaper; it may also be detachable.
AI2s are very similar to AIOs with the exception that the absorbent soaker 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 AIO. Thirsties Duo Diaper could be one example of this.
