I’m a mail carrier so I had to do a bunch of experimenting before finding a combination that didn’t limit dexterity and keep my fingers warm.
I use nitrile gloves as my first layer and then put on different types of gloves with the fingers dipped in rubber or something like it. If it’s bitterly cold I’ll add fingerless wool gloves as well.
The nitrile gloves underneath are cold at first but since you are constantly moving your hands they’ll warm up on their own. If I leave my hands sit motionless they will get cold fairly quick. The key is to keep moving your hands to keep the blood flow going. I’ll use the same system when I’m fishing. When I’m walking out or drilling holes, cleaning holes, I have on a pair of ski gloves.
