What gloves or mittens do you wear on the bike when it is below freezing? I was disappointed in my expensive gore-tex gloves and expensive REI mitten shells. They are only good to right around freezing. Below that and it gets painful. The mitts don't give me extra degrees, they give me an extra couple minutes before the pain kicks in.

I experienced frostbite nearly 15 years ago (due to biking short distances with inadequate gloves), and it took several years before my fingers didn't swell up and hurt in the slightest cold. I hope to find a glove solution before that happens again

I found several threads about gloves and cold weather but I'm not interested unless the definition of cold weather extends to 10F. I'm sure residents of California have good advice on many topics but probably not on this one.

I don't care about too much agility. When I'm biking in that kind of weather I'm just not interested in shifting.
