Depends on the fabric...but much more on the dewpoint. The more wicked the dewpoint gets, the less sweat (or any water) evaporates and the more it just drips.
Here in the USA midwest with 80F dewpoints and 100F degree temps and 90% humidity...any base layer no matter how expensive becomes a sopping wet towel, and stays that way for the duration of your ride.
