I believe those of us who work outdoors and work with our hands, have a distinct advantage when it comes to keeping our fingers and toes warm in the late season.
I know my friends that are on heart meds and what not, all say that they are cold in their extremities and it doesnt seem to matter what they do, other than make sure they have an ample supply of heat packets available.
With the Orvis wool and leather shooting gloves, once the fingers are broken in, I have no trouble at all operating double triggers. They really are a nice glove.
But again I probably have Fishermans hands, so perhaps my hands automatically warm them selves up a little more than some when I am outdoors. Like I am today, sharp tail hunting in the snow at 32. So its cold and wet. But Im not. And my hands are hot.
