I'm 60 now and for the last 10 years painfully cold fingers has become an issue. I was an avid off-road motorcycle rider/racer fall to spring in Oregon frequently riding in temps from 25-45* until 5 years ago, I was also a year round competitive golfer in Oregon.
This is a condition I appear to have at this point:

I shot for an hour and a half last week at the range, ambient was 38* and I had disposable handwarmers in my pockets. In the 20-25 minutes of putting gear away and not occasionally using the handwarmers this is what my fingers looked like after a 25 minute drive home in a warm car:
It's become a real PITA keeping my fingers warm enough to function in colder temps as I age.
One trick I used when riding on road motorcycles was to wear latex exam gloves under my primary riding gloves and that prove to provide the best insulation and still retain good dexterity. I always kept a pair stashed on my road bikes.
I'm going to try some FootJoy or Nike all weather golf gloves with latex liners for my shooting set up next. The golf gloves have thermal properties, come in a wide range of sizes including length and allow good feel.
When your fingers get so cold and painful that you literally cannot use them it's not a good situation.
I also have decent work gloves with latex liners stash in my cars for emergencies.
Hope this helps.
