SD, As you know I use a module system with my kit. That was just my basic hiking kit that will strap to my pack but I have an Arctic clothing kit module that straps to my pack also. It weighs 5 pounds and I can sleep in it so don't have to carry sleeping bag and don't need fires or shelter either.
I use all goose down. Gloves, hooded parker, vest and snow pants. They pack easy too. I just fold and stack them.

Then I use elastic straps with velcro to compress them.

Then put them in a water resistent stuff sack and have cinch straps to fasten them to pack.

It has to be -20 before I even think of pulling this gear out and take no notice of the cold after that.
