Adult diaper

An adult diaper (or adult nappy in Australian English, British English, and Hiberno-English) is a diaper made to be worn by a person with a body larger than that of an infant or toddler. Diapers can be necessary for adults with various conditions, such as incontinence, mobility impairment, severe diarrhea or dementia. Adult diapers are made in various forms, including those resembling traditional child diapers, underpants, and pads resembling sanitary napkins (known as incontinence pads). Superabsorbent polymer is primarily used to absorb bodily wastes and liquids.

Alternative terms such as "briefs", "incontinence briefs", or "incontinence products" are also used.
