Skate or Swing? Why choose! Our Slackers Skate Swing uses skate board inspiration for the wooden base. Powder coated steel for the adjustable height hand holds. PP adjustable length rope with 2 attachment carabiners. Our base has a non slip foam top with printed graphics on the bottom. Rock back and forth for momentum. If using with the Ninjaline, use the included reinforcement straps to protect your line. Hang from a tree branch or structure for fun for ages 5+
