The Light Casting Gloves will keep your hands warm this winter. They have a “wind- and water-resistant outer shell, polyester insulation that keeps hands warm, and a brushed tricot lining that is soft and smooth against hands.” They also have a synthetic leather palm for improving your grip and elastic at the wrist to keep out cold air. They have fingertips “lined with a conductive material that mimics human skin, affording complete control of touchscreens while the gloves are on.” Finally, each index finger has LEDs secured into the base of the finger that are powered by CR2032 batteries and are switched on by pressing a button on the wrists of the gloves. The included set of batteries will give you about 9 hours of light to see what’s in the bottom of your bag or to help you get your door unlocked. The Light Casting Gloves are available in sizes small through XL for $69.95 a pair from Hammacher Schlemmer.
