I believe some ICs in the UK (and maybe our ABDL friends as well!) who get nappies issued by the NHS may find this interesting.
I am issued iD Expert slips by the NHS for a lifelong bedwetting issue. I recently received my quarterly batch, and as usual they are completely plastic backed. But simply out of curiosity, I ordered a couple of samples from a UK site (Incontinence Choice - check the site out, they have a huge range, are reasonably priced, and they ship very promptly and very discreetly). Anyway, it appears that most of the iD Expert items they stock are cloth-backed, although there are one or two of the smaller sizes (no good to me!) that are PE backed.
It will be interesting to see if the NHS issued ones remain plastic-backed (is it cheaper for the manufacturer to produce them and therefore more attractive to the NHS?) or whether at some point in the future they will go over to cloth backing as well.
Incidentally, the cloth-backed samples I bought performed equally as well as the plastic-backed ones I normally use. I really cannot find any difference, they both keep my bed dry, which is all I ask, so it will not bother me in the least if they do go cloth-backed.
