For years, I’ve been buying two separate cases of Abri Form. One case of large, one case of medium. I lay a large disposable Diaper down first. I cut slits into a medium Diaper and lay it on top of the large. Then I put them on. I can get anywhere from 8-12 hours of urinary protection from them. I can always buy a different brand of adult Diaper that is a single, thicker Diaper, but it doesn’t really matter. The absorbent ratio is about the same. The thick single Diapers appear to be rather expensive also. I accidentally bought a bag of the mega max from Northshore recently. They sit on the shelf, forever, unused, as I didn’t notice that they are the ‘breathable’ type, which I don’t like.
