and since the chamois does such a great job of wicking all the moisture away from your body, I'm sure it doesn't care what kind it is!

Ya can't have TP everywhere ya go. Elastic chafes. Some chamois are antibacterial. (Some folks have problems with the chemicals they use on the anti-bacterial type, if you suspect you might, avoid the antibacterial ones)

To make sure the shorts stay really clean in that area, I always pretreat mine with an enzyme type laundry pre-wash in the chamois area - shout or wisk or some other such thing. That will take care of any remaning bacteria, sweat, and/or odors. Just a fact of life. There are a lot of eppocrine glands in that area which is partly why the chamois is necessary in the first place. If we had the same kind of skin and glands there that we have on say our arms and legs, we would need the chamois for chafing but not so much for wicking.
