I was out doing some Photography yesterday morning at Jones Beach, NY. The wind chill was at least 5 below zero, 14 degrees on my car thermometer with 30+MPH winds. I was on the beach and got a call and could not answer it until I took my gloves off, and Voila, worked like a charm. I used it later as well while taking photos I got an e-mail and took my gloves off and the screen worked fine. I guess it just needs some heat from your fingers, not fabric.
