What they see
To me the un gloved hands and uncovered face are the biggest items seen by deer in the woods.The ungloved hands are like butterfly's and the face a big moon. I can spot a pale face way off, but w/ a face cover it is harder to spot. Also this thing about staring at a deer, how do they know that you are doing it?I never stare/concentrate on a deer in the woods, it's like they feel it, if I drop my stare they seem to ease off the alertness. Maybe I'm nuts (LOL), but try that and see if it doesn't work.
