I've been wearing the TENA Ultra's for a while now recently, and I have to say that, for a thin, quiet, cloth backed diaper, I'm really impressed.
It's been my day time diaper, as while I don't typically flood it during the day, it is very resiliant to leaks. I've honestly never had a problem. Attends w/ waistband, which is plastic backed, seems to be about the same size and thickness, but I seem to ALWAYS leak in that diaper.
I noticed there are old threads on the TENA Ultra, but I thought I'd give it my praises regardless.
I like the cloth-backed diapers for day time use also because if you have to go #2, its so much easier to take it off, do your business, and then put it back on with no issue.
