Abstract: The invention is a diaper comprising an impermeable outer shell, means for securing it around the waist and legs, and a set of multiple absorbent pads located inside the shell. Each such pad in the set being positioned and adapted to receive and hold liquid and solid waste in turn. Each pad being easily removable after use, through suitable openings in the shell, leaving behind a clean pad in its place for subsequent use and removal. Each said pad comprising a top layer of absorbent material lined with a lower, thin layer of impermeable material designed to hold liquids and keep them from seeping downward to the next pad in the stack, an end tongue or handle for puling out of the pad stack and out of the shell, and an integral (plastic) bag or enclosure to isolate the used pad.
