This ultralight leash comes standard on our Pro Series models. At just 3 ounces it's 60% lighter than our standard coil leash. The 6 foot length stretches up to 9 feet in the event you fall off your board to minimize strain on your ankle. When not stretched out it stays out of the way and out of the water to prevent drag. It also flattens down when you step on it to futher minimize any impact on your paddling experience when moving around your board.
