MacBook Pro :: Warm Gloves That Allow Typing?

The Mac Lab at my school has terrible temperature regulation. It's in the basement of an open floor plan building, and during the winter it gets so bad in there that my fingers go numb. Obviously these are not ideal conditions when you are trying to work with a keyboard, a mouse and a wacom for hours on end. I'm wondering, does anybody own or know of a pair of gloves that happen to be thin enough to allow for typing yet still keep your hands warm?

I tried googling for a bit but all I could find were gloves with the fingertips cut off. I think I must have poor circulation in my hands or something because my fingers and toes seem to stay cold most of the winter regardless of how warm my body is. And working on a computer in a cold room just makes it exponentially worse of course.
