I love the wool beavertail vest by KOM. Great for layering and not bulky. Wear mine over good moisture wicking underwear top and wool shirt. My arms never get cold and sleeve never a concern when shooting cause there is no sleeve. Anything with the windstopper lining makes me sweat when walking into my stand. Good luck and Keep'um Sharp.  

Like others have said the jacket is not the only answer-layers are the most important and hat and gloves-socks and boots too.
Wool and polypropylene are best. Your base layer is key-I lived in Northern Quebec, Ontario and Finland for more years than I can count-always outside in winter-that was the only time of year to be free of bugs!  
REI, Cabelas as well as others, have a good selection.

Just hunt naked. After frostbite, you won't feel a thing. And no bulk.

Sorry, I was bored at work.

Wool in layers is what I wear. Thin thermals, wool sweater, then my wool coat. Works well for me.      Yes I need help.

I like a wool lumber jacket with a light nylon wind breaker underneath to cut the wind.

You have a PM Mitch.......

Get whatever jacket you choose at least one size bigger than you usually wear so that you can add a layer under it if you need to without making it tight and binding.
I'd go with a medium weight wool jacket or pullover. Sweaters are made to be an intermediate layer not outer wear. They add loft between the jacket and the shirt with addition insulation.
