Good for the elite of not feeling cold then, that would be great. Wind doesn't hit all parts equal either, so just because you are clothed the same doesn't mean everything warms the same, we get some pretty crazy winds, one nostril freezes where the other doesn't type winds. I have ran in shorts for races that were freezing and I felt cold, maybe my glutes & quads were warmed up, but I still felt cold mostly on my thighs and butt. Maybe that's the difference here in what we are both saying, feeling cold versus warmed up muscles. So my muscles might be warmed up, but my skin sure isn't.
