panty liners?

So a couple of days ago, I saw a blurb in the Boston Globe about a new cotton fabric for ladies' underwear that is treated with a antimicrobial. One of the advantages of this fabric was that it would "eliminate the need for panty liners."

Have I, in my unlined cotton undies, been unknowingly offending the masses with my _feminine odor_?

Interesting comments, everyone... I guess that when it comes to panty liners, as with everything else, YMMV. I still wonder how many women use them on an everyday basis.

I've been tempted a few times, on really hot summer days and with long flowy skirts.
