Hang the 30' Ninja Line between 2 trees for a challenging, flexible training obstacle course. Train like a Ninja with this set that was designed with input from professional Ninjas! Comes with bars, fists and rings to attach at intervals and to adjust for difficulty, allowing you to create a variety of courses for a unique set of challenges. The line uses heavy duty webbing with double sewn pockets and steel reinforced ratchets with rubberized grips. The obstacles use nylon and polyester rope with UV treatment, solid wood and steel rings with rubberized grip, and include a steel safety delta clip for easy attachment. It all fits in a sturdy carry bag. Develop core, grip and upper body strength. Add the 8' climbing rope (sold separately) with footholds for extra ninja action! For ages 5-12 yrs, from B4 Adventure.
