A diaper slip is a diaper that you pull up as underwear. It is convenient to put on and take off, but still absorbs moisture and often feels dry to the touch. You can use diaper pants as an intermediate step between diapers and underpants.

Or, for example, during special moments: during a longer car ride, a child wears diaper pants that are easy to pull down by themselves at a stop.

This is how it helps: getting on and off is quick and independent. That gives convenience in moments when the toilet is not immediately nearby.
