I've spent way too much time looking at base layers and puffy's.......................
I've also been trying to understand warmth/heat measurements, specifically 'clo' units. I estimated the clo numbers for all these puffy's The RAB Neutrino and Sitka Kelvin Down Hoody have insane clo numbers and should be good for north pole hunting <G>

I have several of these, notably the Browning midweight puffy. It is really warm but doesn't have a hood. Also, take a look at the EMS Feather Pack - I bought one on sale a few weeks back. It is the real deal. What I don't know about it is how well it conveys sweat. Most of the hoodies listed have some type of moisture conveyance system.
If the clo thing interests you, here is a table I found. A couple of salient points. First, the best synthetic is Primaloft Gold (unless something newer is out), note it falls in about equal to 600-650 down. Most of the other Primaloft equates to 550 down. Second, I'd not due a down less than 800 over a good Primaloft puffy. The 550 might be lightweight but lacks anything if it gets wet.

550 fill Down 0.7
650 fill Down 1.0
800+ fill Down 1.68
Climashield APEX 0.82
Coreloft by Arctyrex 140 grams/sq m clo = 4.01, noted to be 5% less than Primaloft One
