What type of insulation rating do they have? I am comfortable with 400 gms of Thinsulate to a -40 but you might not be. It really all depends on how your circulation is in your feet and what you really consider comfortable.
There are times when the deer are simply not moving and you're forced to make something happen. Maybe you're up against a full moon or hot weather. This is when a silent drive to force deer to move should be considered.
By silent drive, you're not yelling and making a commotion to scare the deer. When deer are panicked, they're liable to bust out of the cover on a dead run, and any shot you get will be tough to make.
