pocket diaper

noun1

   (US, Canada) A type of cloth diaper, secured with snaps or velcro, that consists of a waterproof inner and outer layer sewn together, creating a pocket, which is stuffed with absorbent insert material based on a baby's absorbency needs.

   • Made famous by Fuzzi Bunz, the pocket diaper is an all-in-one with a pocket sewn into the lining. You can then customise the diaper for more absorbency by adding an insert or a prefolded diaper. — 2007
