The M4’s are indeed quite good, and are at the top of my list right now, But I’ve only tried a handful of different brands and types so far. The M4 was actually one of the first premium diapers I ever purchased.
I try various brands from time to time, but the Abena M4 has been my regular daily diaper for the past 10 years of so. They have a high capacity, fit me very well, and Abena has excellent quality control. I very rarely find a diaper that is defective in any way.
Abena M4’s are my favorite diaper. They hold a lot and personally they fit me very well. I can usually have an M4 or about 20 hours at a time if I choose to do so.
M4’s are a really good diaper with high capacity. They are one of my favorites. But to be honest I’ve got several favorites: M4, Molicare, Northshore briefs, & Bambinos.
