ManMat's 2 Dog Ski Line Fin is great for dog scootering, bikejoring, canicross or walking with two dogs.
About 220cm long before stretching and about 260cm long when stretched. It is 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.
