It's 1989. Bicycle enthusiast Michael Eidson, is competing in the "Hotter'N Hell 100. Eidson, an emergency medical technician by trade, decides to fill an IV bag with water and slip it into a white tube sock. Yes, a tube sock. Then he stuffs the contraption into the back of his bike jersey, and throws the thin hose over his shoulder. Hands-free hydration is born.
