For a while I was making due with size 6 and 7 baby diapers, not ideal but I found a way to make them work (As a DL) for short periods of time.
Basically I would stuff one diaper with another and use 2 sets of tabs to get a snug fit.
Eventually I ordered cases of different high quality adult diapers from XP medical and I found that I love (love love love love love, lol) Seni Quatros, also love Abena M4s and Molicare Super Plus a lot, but unfortunately those 2 seem to be getting made in lower quality these days, and I also tried dry 24/7s and the Absorbency A+ diapers (made by or for XP medical, I don't love or hate them or dry 24/7s compared to Seni Quatros and Abena M4s and Molicare Super Plus).
I think M4s were my first good adult diaper I tried, and still remain among my favorites, but ABU diapers are making their way into my favorites, my current favorite is Little Pawz and I also have a case of BareBums to wear for a while until I order more variety or get more Little Pawz (which I still have some of and will wear them sometimes).
Sorry for the semi-long rant type post lol.
