The Earthing® Recovery Bag Kit is a poly/cotton blend sleeping bag (40"x84" zipped up) or sheet (80"x84" lying open) containing woven-in conductive silver fibers.  The Recovery Bag connects to the Earth with a ground cord.  One end of the ground cord snaps onto the Recovery Bag and the other end connects to the included ground rod system.  As your bare skin touches the conductive bedding the energy of the Earth is able to flow into your body grounding you as you sleep.  Originally designed for Tour de France cyclists, the Earthing Recovery Bag is being used by a growing number of professional athletes worldwide.  Great for travel!
