The Swingline™ is the newest addition to the Slackers® backyard adventure! 

From the creators of the Ninjaline®, Slackers® Swingline is the perfect introductory line for those little ones full of energy and ready to start building their upper body strength and swinging skills.  

Kids can easily move through the course and rearrange the line of activity as desired. First, they can start by swinging back and forth or hang upside down from the steel monkey bar. Then they can swing like a monkey from one gym ring to the next before landing at one of the lightweight mesh swings! 

With two extra Grip Clips, additional obstacles can be included along the line for extra fun: such as the Skate Swing, Ninja Twister or Ninja Wheel (available separately)!

The entire kit includes a carrying bag for an easy portable swing set to take to the park or store away as needed
