Kids exercise and train like a Ninja with our patented 50-foot Slackers Ninjaline Intro Kit and the 9 included hanging obstacles. The 56-foot Ninjaline includes 18 double-sewn durable pockets to customize the arrangement of obstacles, and add on more like a Rickety Bridge, Ninja Twister, Cargo Net or Climbing Rope. Also included is a traverse ring to use for larger gaps between hanging obstacles, and 6 Grip Clips which allow you to add two more obstacles on to the line and arrange wherever the kids desire!
