None of those single gloves work well enough for me. Once I spent a lot on a supposed super warm Gore windproof glove that did basically nothing to keep my hands swarm.
i wear 3 pairs of gloves in the below 40F weather. A thin 100% cashmere ladies' glove as a liner, a regular polartec type warm glove, and a soft large men's ski shell glove with poly-down lining, that slips over the other gloves easily and leaves a little insulating air layer. Even with all 3 pairs on, I have no problem working my brifters. WARM. WIND PROOF.
