A while back in 2020, during lock down when I was stuck in the UK I ordered and tried a pack of out ABU Simple Ultra adult sized disposable diapers/nappies.
And these where where amazing not only are they extremely comfortable but also very absorbant coming in at 6,250 mls or 219oz of liquid which in my case came in extremely handy as I have a tendancy to leak in ordenary/regular store bought diapers
This usually happens whilst I am asleap as and this can be very embarrassing as I am a hevy sleeper plus I am partially incontinent due to factors outside of my control, see my previous replies for more information if you haven't already done so.
Unfortunately they didn't come cheap but that's something that I was glad to find out as they where excellent quality over all and because they came in all white which was good
They usually come with no markings and thas far where the closest reminder to me of the old pampers diapers that I spent the better half of a decade in and out of as a child,
They also come in an option to have scent added like the original pampers perfume, although I didn't go for that option this time around as I have always had sensitive skin
and perfume sometimes has the tendancy to make my skin come up in rashes, which isn't great at the best of times to say in the least.
again see my previous replies if you have not done so already.
And all if I won the lottery I would invest in multiple pairs of Maximum absobancy diapers/nappies, and wouldn't care about the cost as long as I could invest in a carer who would see to it my needes where fully catered for but maybe thats for another days subject.
Although when It comes to wearing diapers, at the time of writing this I am an autistic adult male who is in his 42nd year of life as of October 2022, or at least in this life-time so I am still young.
Anyway this is my reply to your post and hopefully it will help other people.
