staying dry on the walk in is key also. Work up a sweat on the walk in and you won't last long on stand.

Think in layers, polypropylene or sweat wicking fabric on your skin, fleece, then wool or goose down insulation, and a good windbreaker layer.

The heater body suit is awesome when temps get below freezing and in windy conditions. It's like you never rolled out of the warm bed

Check archerytalk for reviews on the HBS. Lots of Minnesota and Wisconsin guys wear the HBS when it gets cold in the late season.
