I'm not sure what you're getting at. That they're cooler than cotton? I completely agree with that statement. I disagree with the implied assertion that wearing a wicking baselayer under a cotton dress shirt will keep you cooler than wearing the dress shirt by itself. Showing sweat, as other posters alluded, is a different issue.
Tangentially, I strongly disagree that wearing a wicking tshirt is cooler than wearing no top at all (under the vast majority of circumstances).
You see, there was no "implied assertion" about "a wicking baselayer" that cools. (If there were strong evidence of that, the claim would appear in the website's article about undershirts. Even the counterintuitive possibility that an undershirt minimizes sweating by lessening physical and psychological discomfort from top layer dampness is not worth including in the article. But enough with the subject, okay?)
The assumption was that, like most people probably do, he would be wearing an undershirt, in which case silkweight would be more comfortable than carded cotton.
A strong antiperspirant is a good idea, too.
