Once the weather starts to get colder, my hands are freezing much of the time. I am sure that there is some type of circulation issue. Consequently, I have tried many different gloves and none have really done the trick. It was one thing that made cold weather riding nearly impossible as I often was in pain and barely able to move my fingers. Currently I have been using a set of battery powered heated liners under a larger pair of gloves. This has worked fairly well.
