Heater Body Suit. I gaurentee you will stay warm all day. Its not an article of clothing you can walk in. Its something you put on after your in the stand. I zip mine up about 2/3 of the way and drop a hand warmer or two in it and honestly Im good for all day if I want to stay that long. Retails for about $300 when I got mine. I used to have terrible problems with my feet getting cold but I bought a pair of Irish Setter Snow Claw XT boots and they truly are the S**t. 2000grams of insulation and my feet are never cold. Good luck with whatever you decide to buy.
