Nanotechnology Gloves Keep Your Hands Perfectly Warm

The Chaval Response-XRT are a pair of gloves that will warm the hands (and hearts) of every geek. They seem to come right out of a futuristic movie. Proprietary, paper-thin, nanotech polymer film automatically regulates its own temperature using temperature input from each of your fingers and compensating as necessary. This requires power so the gloves lithium-polymer battery system can last for 4 up to 6 hours.
The gloves are a very high-end product ($390) and are designed with maximum comfort in mind. According to the manufacturer: "You shouldn't feel the electrical components, batteries or wires when you put on your gloves. You shouldn't feel anything but heat." The gloves are also waterproof, so they can be used in rain and snow.
