Start with Under Armor and layer with fleece. Second bow season I carry in a jacket, Autumnwood wool archers jacket. Big dollars but this thing works.
http://autumnwoodoutfitters.com/catalog5.htmlHand warmers in both mittens, and boots. NO cotton any where, boots at least 1 size larger for the heavier wool socks. You don't want any constriction to limit blood flow which will drain warmth from your body.
Lower, I do the same with layers but don't have the wool bibs, just stick with the fleece bibs I have.
Good hat and fleece neck gator that can double as a face mask if needed. These are small items but are key elements to have.
Biggest key is to strip down to min cloths and walk slow to the stand. Take your time to minimize or ideally eliminate any sweat. Slowly put all your clothing on once in the stand.
I have sat in negative teen weather with OUT the wind chill. Don't even want to know what it is with the wind chill factor.
I'll admidt it's not all toasty warm, but is do-able. 10 degrees above zero and little wind is like a heat wave wearing this set-up.
