6 1/2 ft long before stretching, about 8 1/2 ft long after stretching, made out of 1 inch wide tubular webbing with built-in bungee for each dog. Having a double bungee ensures good, evenly distributed pulling power and reduces tangles from dogs not pulling equally. Can also be used for canicross, bikejoring and dog trekking. One color only. A note for beginners: There is no need for a very long skijoring line. The longer line - the more tangles! The length of our line will be just perfect for you!
