PinkPilot, did you ever get the jersey and try it out yet? I just wanted to update you on the rain aspect of it. I went on a 78 mile ride last week, all but 15 or so was in the rain. My biggest worry was that black spandex-y type panel in the back, thought for sure my back would be soaked. But wasn't. I was covered in road grime head to to and wringing water from my gloves and socks but was still warm and dry underneath. I did notice that when I bent my arms I could feel the squishy sensation of water being pooled but was dry underneath. Granted, my jacket felt 5#'s heavier but I was still warm and dry (at least what was covered by the jacket!) while I was riding. When I stopped to take a break, I got rather chilly but that didn't last long once I was back out on the road again. The temp was around 48-50.
