All-In-One (AIO) diapers are an easy and convenient diaper solution. AIOs are their own entity - the absorbent inner is connected to the waterproof outer - and are the easiest cloth diaper option on the market. At each diaper change you change the entire diaper.
Pros: easy to put on, easy to pack in diaper bag, trim (aka close-fitting), no learning curve
Cons: can take longer to dry, more expensive
