Ebay is a great source for all kinds of unlined gloves - not just household but some of the longer and thicker surgical / obstetric & gynaecology gloves are amazing!
Household favourites of mine are Ansell Duzmor Plus. Try searching ebay for "Duzmor" and you'll find some of these. They seem to soften slowly with age, I've got a few pairs from old stock that are so smooth and soft inside, I can't quite believe it!
If you don't mind a large size, these are just HEAVENLY in terms of feel and texture:

These are marked as a size 9 but more like an 8.5. I would slightly prefer a smaller size, but they feel so incredible (both for f*cking when lubed inside, and for stroking on skin turned inside out) that I've bought two lots of 20 already.... ...stocking up based on past experience when I haven't and then the gloves are gone.
Marigold G31H ( Featherweight Plus ) are really nice too, though the smoothness inside can be slightly tacky and these really benefit from CAREFUL home chlorination.
I've yet to try them but the Vileda Professional unlined that's listed by Hygi.de looks really tempting, easy to order online and actually very similar in appearance to the Ansell Duzmor Plus.
Finally Ansell also sell a glove in Italy called "Supersottile" (translates as "super-sensitive" I think). These are very nice - I had the exquisite pleasure of "borrowing" a pair from an hotel service trolley once, couldn't help but take them back to my room for a quick session
! They're unusual these days in being offered in half-sizes, though only up to an 8 - presumably the Italians are targeting their sexy ladies! Some of the Italian on-line pharmacies sell these gloves on ebay, although you may have to buy 24 pairs. They're cheap though, and IMHO a really good investment - who knows when these divine gloves will be discontinued.
Happy hunting, get them while you still can - these type of gloves seem to be slowly disappearing from the West, supplanted by vile nitrile and boring flock lining
