Though the Slackline and Ninjaline are both made of the same material and feature the same ratchet system, they are still unique from each other. The Slackline is designed to be mounted just a few feet above the ground for the purpose of balancing on as you walk across, and the Ninjaline is meant to be mounted higher above the ground. It features integrated sewn in pockets and delta clips that can attach Ninja obstacles onto your line. If you are looking to build your own Ninja obstacle course, we recommend purchasing the Ninjaline. If you already have a Slackline, we recommend using our Ninja Grip Clips to build your own makeshift Ninjaline.
