We love BumGenius diapers. We use the Elemental ones for Elias and sometimes Josiah. Before Elias was born though, and before we had very many BG AIO's, I bought a load of prefold diapers to use with a cover. They work great, are super absorbent, and are crazy cheap (about $2.50 a diaper).
But they look like this (without the cover on):
I mean, really. They look like something an Appalachian baby might wear.
