Where can I go to buy hospital grade adult diapers

I would like to try hospital diapers but idk what kind of diapers they use.

Hospital grade are THE CHEAPEST THEY CAN FIND they just change you more often and usually the bedding also ....your better off using klenex

You can most likely get whatever types the hospital uses at medical supply stores, but you'd probably have to buy a case of 128 (or some ridiculous amount).
