My hand have been frozen to many times ,so they go in to memory shock the second they feel cold.
The blood moves out of the fingers to protect the heart. enough is enough !
I have tried the Canadian goose mitts with those heat packs I have thrown in .
The down after one season moved from the inside of the palm to the back side of the hand ...no good !
Many mitts I have looked at, have gloves inside them......not good .
Thought of getting some heated mitts.... not to good when power runs out ...not good.
What else is out there for -35 to - 50 C
