Which CD side to touch the plastic sleeve?


I have a number of CD holders where one can carry a large number of CD's each in their own plastic sleeve, with a soft cottony insert material to press against one side of the CD, and soft vinyl plastic to press against the other side of the CD.
My question is whether the softer cottony material side is intended to press against the playing side of the CD?
The product illustration shows the playing side pressing against the soft vinyl plastic side of the sleeve, which seems wrong to me.
If I can learn how to use these holders then I can shed a lot of weight when traveling to audition components (without giving up rich desserts), by replacing my old portable transporter boxes which simply carry the complete CD jewel cases, just as they stack side by side on a bookshelf.
I realize what a high tech question this appears to be, but inquirying minds need to know.

Thanks everyone for such thorough answers.
I'll probably just continue to use my regular weighty carry cases with the regular CD jewel cases inside so I can be safe with all my original CD's, when on my way to an audio store, or club meeting.
My cars are so old that I still listen to cassette tapes with the in-dash player, and always take a few tapes along when driving. Luckily, none have melted in the heat.
I have accumulated quite a collection of cassette tapes since so many audiophiles have gifted me their old tapes now that CD-R's are preferred.
I never let the originals leave my listening room, and they always stay in the jewl cases. That seems to be the best way to insure that they stay near mint. But when traveling or in the case, I use burned CD-R copies in those plastic & cotton sleeves. That way I don't what happens to them. It seems to be the best compromise for me at the time.

Is there any reason why you are taking the originals with you?
Always use jewel cases for best protection against disc damage! Forget the convenience of those nasty plastic protectors!
I'm with everybody else...I ruined a bunch of cd's with those plastic sleeve holders and wouldn't ever consider using them again...jewel cases for me now.
You could replace the standard jewel cases with the thin ones sold for cd-r, to reduce the weight and bulk, and increase the capacity of your carrying case.
