Between the ravages of disease and a head injury when I was younger, I don't control my temp right at all. In the summer I can overheat, but sweat finally kicks in and I can make it. Not comfortable like it used to be, but I make it all right. But in the winter, my body has a very hard time handling the cold. I know that the deer are not going to give me a free pass, so for those with poor circulation, what do you guys use to keep you out in the field? Any tricks, or is it really just down to gear?
