New to winter riding - what clothes I must have?

[lph]

If you ride at high exertion it is often too hot to use a rain jacket. We used just get wet in moderate rain.

Ok, I should have specified that I was talking about sub-freezing temperatures, and getting wet from the inside, from sweating. To me rain isn't winter :-D

Which was a pointless assumption on my part, because keeping warm in cold rain is actually a lot harder than in severe "winter" cold. I agree, it's often too hot to use a rain jacket, and the only ones I've found work well have massive vents everywhere. Best you can do may be to get wettish.
