polypro glove liners
I keep a pair of polypro glove liners in my car. They are soft and thin and inexpensive. Nice when the car is really cold in the morning.
At the range, I wore them while setting up targets. Forgot I had them on and fired a few mags from my 1911 and my G17. Warm hands are probably steadier hands. These are OK with temps in the 50s, but not heavy enough for colder climes.
