Thanks for the input guys. The one that seems to be getting pushed the hardest at REI and Moosejaw is the Patagonia hooded down sweater. I went and tried some on today, and it felt pretty good, but I'm not sure about the warmth with it being so darn thin. The MHW Sub Zero is another popular one, as Fishmonger pointed out, and that one was pretty comfortable as well.
Appreciate the advice!
