This article introduces current pads for pull-on adult diapers, including products labeled “thin” or “slim” and products designed to fit neatly inside the diaper. Official manufacturer pages were checked on October 2, 2026, and widths, lengths and absorbency guides were compiled.

What are pads for pull-on adult diapers?

These pads are placed inside pull-on adult diapers. The pads introduced here have a folded-in-half shape that makes them easy to insert. Application methods vary by product, so check the package or manufacturer’s guidance before use.

Current products by manufacturer

“Ultra-thin,” “slim” and “neat fit” are each manufacturer’s descriptions; pad thickness cannot be compared from width and length alone. Decide when to change the pad according to urine volume and conditions of use.

Points to remember during use

Place one pad inside the pull-on adult diaper. Layering several pads can cause leaks, so do not stack them. Secure Lifree’s anti-slip tape to the diaper and avoid direct contact with the skin. For detailed positioning, see Unicharm’s instructions and Kao’s instructions for further guidance.
