Office gadget in winter

In the winter, sadly, there is such a thing as frost. And everything would be fine if he did not penetrate the premises. It seems to be plastic windows, and heaters, but sitting at the keyboard and mouse, you involuntarily catch yourself thinking that your fingers are starting to freeze. I thought today, why not close your hands from the cold? Mittens inconvenient, what other options are there? The following came to mind, maybe a comic decision, and maybe someone will save hands and health:

Material fabric or wool, on the right side to put the zipper and go! Hands pushed through the holes (sleeves) into the inside, where the keyboard and mouse with a hard mat.

I see two minuses at the device:
1. It is necessary for turning the paper, or other operations to reach the hands.
2. We have to work hard in the actual sense, which in a sense is a plus.

I called WarmWork, if someone makes a pattern and starts production, I will be glad to purchase it.
