Abstract: An arm protective garment includes an elongated tubular sleeve made of a flexible fabric and defining an elongated internal cavity extending between opposite ends. The sleeve is open at one end for slipping over a driver's hand and arm and for receiving the driver's arm in the internal cavity of the sleeve. The garment also includes a mitten of flexible fabric disposed on the other end of the sleeve and defining an internal pocket for receiving the driver's hand therein. The mitten has only a thumb opening defined therein for extension of the driver's thumb from the mitten. The garment further includes a flexible strap attached to the one open end of the sleeve for encircling the neck or chest of the driver for releasable reattachment to the one open end of the sleeve to retain the sleeve on the driver's arm.
