I find this to be the case. I even went so far as to get a skinsuit for doing duathlons, but then I gained weight and was too self-conscious. And the bike portions of those races is relatively short, anyhow. I've not done anything longer than olympic distance. Not having that waistband is so much comfier and the chamois doesn't seem as prone to slide around and chafe, either.

Now my favorite chamois needs to put in a short that is truly easy to pull down for bathroom breaks.
