I bought some of Cabela's Polarteck top/bottoms, and it's very warm. When it gets REAL cold I wear Under Amour top/bottomswith the Polartech over it. Then my insulated camo over everything. Awesome combo!
For my hands (bad circulation) I use a hand muff with three Grabber hand warmers inside. Again, awesome combo! And for my feet (bad circulation)I wear Northern Outfitter's Expedition Boots with a Grabber hand warmer under my toes. These hand warmers, which I think are the best out there,come in a 24hr duration, and they cost (.99)the same as the lesser duration warmers.
