Winter clothes to pack...
WHATEVER YOU DO...DO NOT WEAR COTTON ! WET COTTON DOES NOT INSULATE ! YOU WILL GET COLDDD
I have not been in the winter, but plan to at some pint...If winter in Germany is anything like a Canadian winter, then trying to keep your pack under 40lbs, might be difficult....
I will suggest for those really cold days, you get a Gor-tex or Thinsulate pair of pants...these are water proof and will keep you warm in some pretty harsh weather..some might be a bit $$$ but you will thank the lord you have them :-)
As for the rest of your gear, you will need some wool socks, gloves, and long under wear for sure...Wool sweater will be heavy, but you might wanna bring one (turtle neck)...Cargo's with layers under.
Hope that helps ya a little bit anyway :-)
