Hey Kimba

No idea why, but just wanted to add that I have that problem too. On particularly cool days, I get SO cold after the ride. If I had to drive to the start of the ride, I go home with the heat on full blast. Then I take an extra hot shower to try and thaw out I do wear a wicking long sleeve top under my jersey, but apparently that doesn't really matter. It's so nice to have it warm out now. No more layers of clothes and no more of that nasty chill!
