Excluding first criterion - Patagonia Mix Master Pants. Despite some insulation (yes, I got "hot" really fast, I mean REALLY) and therefore added weight, these are my pants to go for winter conditions. Maybe too warm for -5 C and higher, but without baselayer for temps below -10 Celcius they are fantastic.
I have them in use for 4 years - skiing, snowshoeing, biking in winter etc. Love the fit, wind resistance, breathability, snow-shedding etc. Plus couldn't find better option as they were in WebSpecial for $90 :).
You may try to look for other pants made of Power Shield / Power Shield Pro (they come also in no-insulation versions) or Schoeller Dryskin Extreme fabric - check Montane, RAB, Patagonia, Mammut etc.
