The thickness of the diapers is similar.
Both are cotton like cover which makes the "Sticker" not secure as needed. During the sleeping, the diaper stick may be loosened. So, as a diaper user, you should know that the sticker cannot hold the Wet Diaper in place.
The Abri Form M4 is a little bit too big for me. however, the cotton like cover is softer than the cover of Nateen.
For the absorbency, both are similar. You do not have to worry the leakage during sleeping.
However, the Abri Form is more expensive than the Nateen ... It costs more than HK$10 per diaper. The Nateen only cost about HK$5 per diaper.
