The fatty skin on the sides has less air blowing across it than your
belly. If you ride with any lean forward, much of the air hitting your
upper chest is diverted down to the crease of your hips. The sides
just get the normal airflow streaming off your body. I've noticed the
same phenomenon at colder temperatures where I can still ride with a
jersey untucked. The cold air blows in and cools that area more than
anywhere else. I've found that bib shorts help immensely in keeping
this part warm in colder weather.

Well, none of the other theories really make sense to me, so I'll
invent a new one.

I suspect the position of your belly is such that the jersey lies flat
against that spot, and so you have no insulating air space right
there. You've probably got enough air flowing through the jersey to
evaporate a disproportional (relative to the rest of your abdomen)
amount of sweat from that area, leading to excess cooling.
Alternatively, the sweat conducts heat through the jersey to the
surface, and it's evaporated there.

I notice something similar under a couple of conditions; either cool
with no wind jacket, or a good bit colder with a jacket, when I don't
control moisture well and end up with a good sweat. Doesn't happen
when it's really cold, and I have an extra pile layer between jersey
and jacket, IME.

And unless you have six pack Abs there is more fat on your belly then most
of the rest of your body and it does not circulate blood as well. Us older
folks have that even when I work out in the gym. Bill

how old are you?--sounds like a vascular problem.

i suggest a good physical exam as it could be an indication of other
problems

Your love handles aren't exposed to the wind like your belly.

It's pretty common knowledge (around here at least) that fat on the
belly for guys and on the ass for women gets cold when xc skiing. I
doubt if the ass would get that cold cycling since it's not really out
there in the wind, but my wife doesn't cycle in the winter so we dont
have direct experience.

Perhaps you should run some scientific experiments with your wife
riding to resolve this?

Frank,

I got home about 10 minutes ago and my belly is still cold.

Who knows?

I didn't say it was. FWIW, it'll be -7 deg. C tonight.
