I'm semi-retired and drive a paper route to help make ends meet. I wear diapers for that, too, of course. There is a lot of shifting around in my seat and climbing across the car to deliver papers out of the passenger window. The diapers get a bit of a punishment test; clumping is frequent in every brand except Dry 24/7.
Anyhow, yesterday I was delivering papers and enjoying two Dunkin Donuts donuts and some of their hot coffee. I spilled some of that coffee on my lap. It was then I realized that diapers work both ways, as my tender parts were protected from the hot, wet coffee. My pants and the car's seat were not. So, diapers work both ways. I thought it ironic that folks would see my wet pants and, perhaps, think I peed myself, not knowing that I do, but that they'd never see it.
Also, the other day my Abena disposable diaper leaked a lot, but it leaked into the lined plastic pants I wear. That extra insurance has never failed me.
