We live in MN and it gets pretty cold, what temp is this jacket good to?
You would do better to look into a great waterproof down jacket or coat. Down is the very best insulator, and as long as the shell is waterproof (GoreTex, for ex.), and there are adequate 'pit-zips', you'll do fine! Look into Patagonia's Primo Down.
