Pads for pull-on adult diapers from seven manufacturers and their number-of-voids guides

Hiroshi Yagi

This article introduces one retail pad for pull-on adult diapers from each of seven manufacturers. Check width, length and breathability as well as the number of voids.

What does the number-of-voids guide mean?

The number of voids is based on 150 mL per void. Actual urine volume and change intervals vary by person, so also check how neatly the pad fits inside the pull-on adult diaper and how it feels when worn.
