Pros

Highly absorbent.  Need to be used with a diaper liner, so poo can be easily lifted off the diaper and disposed of in the toilet.

Easy to fasten.

Contain messes well due to the elasticated leg holes.

These diapers, depending on the absorbency of the inserted layers, can be used more than once before washing.

Cons

Not waterproof so diaper covers required.

More expensive than the prefold diapers.
