I’m happy with them looking ‘meducal’ after all incontinence is a medical issue. I’m not sure I’d be happy in an adult nappy that had prints on it.
What I would like to see is better anatomical design. Do any of the people who design/make these things actually wear them? All too often I find that the rear of the diaper/nappy does not come up high enough onto the waist, so they don’t stay up. Better leak guards too.
