I have been searching the web for devices available for warming the hands and reducing Raynaud's attacks. The most promising ones seem to be Firzone infrared heated gloves with Li polymer batteries (though these might be a little bulky). Then there are Thermogloves Rechargeable heated gloves made from a thin flexible material which would make manipulating things with your hands easier. Another type of glove, Prolotex Far Infrared gloves that don't rely on any form of battery would seem ideal.
Then there are the handwarmers, specifically the Thermo-slim and HotRox rechargeable units and the Zippo handwarmer that uses lighter fuel.
I wonder if anyone has any experience with any of these devices. It would be really useful to hear about them to help decide which device/s to purchase..
I also came across Thermax Warming Cream - I wonder how well that works.
