THANK YOU, Wow, for all the responses. The Heater suit looks good for sitting but I have to consider the shooting options. I'm not just sitting in the tree at -10 for fun, I'm there to shoot a deer so planning for the shot has to be considered.
As far as the chemical warmers, I should own stock because I probably spend $200 or better each season, pair on top of toes, pair under toes, pair in the muff, one or two body ones on my back and or chest. I have wondered about the electric vest and socks, any info there?
I will look into all suggestions given. Was wondering about army surplus wool? Worth looking into or not?
Thanks again,
Best of Luck,
May your blood trails be short,
