I was wearing fingerless gloves, and no jacket. The tech shirt + jersey I think allowed a bit too much ventilation, on the front anyway, which is why I felt chilly most of the way in. I actually felt chilled all morning yesterday until about lunch. I sweat like crazy when it's hot and/or humid, but yesterday morning I really didn't break much of a sweat at all. I was also wearing a backpack which usually gets drenched, but yesterday it did not.
