My most-worn pullups are Always Discreet. They're fantastic for when I need a simple, quick, and discreet diaper for 1 or 2 moderate wettings, or when I want to wear without committing to wetting.
My most worn tape style is Depend Protection with Tabs. The capacity is just enough for me to feel bulky and squishy and wet after a few wettings, and they're still the best-fitting tape-on diaper for me.
My favorite premium diaper? That's a tough one, but I really like NorthShore Supremes and Wellness Briefs.
"Depends Protection with tabs" and all of the other nomenclature that Depend have used for the term "Adult Diaper".
Although I highly prefer other brands (And have tried tons and tons of them), these diapers are still plastic backed, cheap, and in a pharmacy one city block away from my apartment. I'd have to estimate that I've used nearly 200 bags of them recreationally over my life of being a Diaper Lover. Averaging 16 in a bag, that puts me at 3,200 diapers, Which also puts me at roughly 3k in the hole. Geeze, that poor environment of ours.
My most worn, Bambino! Bellissimo's & Teddy diapers make up more than half my collection. I grab a Bellissimo when I have enough time to wear/use (sometimes at work) or a Teddy when time is short but want a great diaper. Love Bambino's (as long as they don't change again).
