Obviously I'd rather wear a jersey, but I'll have a dress shirt on and meetings to attend upon arriving, so I need to be actually dry, not just mostly dry, or kind of dry, or well ventilated but wet. Like it or not, Gore-Tex really does work, it really is breathable as far as waterproof things go (which isn't saying a TON) and for those who need to show up looking presentable, it's a good option.
