Look for sales... I'm getting cold easily, tried many layers/jackets. Have a Columbia down jacket (100$), a Belowzero with slight insulation (180$) and a 686 with no insulation (180$) all windproof and breathable, and with under-arm ventilation zipps.
The down jacket turned out to be contraproductive, I only weared twice cause even on -20°C I run too hot while riding. I found that running hot while riding is the biggest enemy cos you sweat too much and thus getting very cold if not moving anymore e.g. on the chairlift. Wearin too much was what made me freezing.
Thus I now wear as less as possible i.e. the thin insulated one on very cold/non bluebird/stormy days, the non insulated one if sun is shining and above -10°C. Under the jacket I only wear a thin functional shirt that don't soak (no cotton!, e.g. Odlo or Schoeffel) and have an extra fleese layer in the backpack to keep me warm on longer breaks.
