## Description

Ninja Warrior Obstacle Course for Kids - 2*56FT Slackline Kit with 8 Obstacles | Upgraded Quick-Install Buckles (No Threading Needed), CPC Compliant Outdoor Play Set

Review: Ninja Warrior Course - Best thing we purchased for the kids this summer for our tree fort!
Review: Kids Love it! - This is a great outdoor activity. Challenging enough for older kids (and even adults). Easy to set up between two sturdy trees. I would recommend for kids 8 and up as it can be frustrating for those younger than that. It’s been outside for a few months and seems to be holding up well.

## Features

- NINJA WARRIOR FUN FOR ACTIVE KIDS – Turn your backyard into an exciting ninja training course with this 2 × 56FT slackline obstacle set. Designed to encourage active outdoor play while helping kids build balance, coordination, grip strength and confidence through climbing, swinging and obstacle challenges.
- 8 EXCITING OBSTACLES FOR CUSTOM CHALLENGES – Create a different ninja warrior obstacle course every time with 8 fun hanging obstacles. Adjust the spacing and sequence to make the course easier or more challenging, giving kids more ways to climb, swing, reach and move from obstacle to obstacle.
- UPGRADED QUICK-INSTALL BUCKLES – NO THREADING NEEDED – Featuring upgraded attachment buckles, the obstacles can be installed and repositioned more easily without the older threading-style setup. Spend less time assembling and more time enjoying backyard ninja warrior fun.
- CPC COMPLIANT FOR KIDS’ OUTDOOR PLAY – Designed with children’s play in mind and supported by CPC compliance with applicable U.S. toy safety requirements. Durable webbing and outdoor-ready components make this ninja obstacle course a great choice for backyard play, parties, camping and family activities.
- FLEXIBLE BACKYARD SETUP & EASY TO TAKE ANYWHERE – Install between two sturdy trees or suitable poles approximately 15–45FT apart, then customize obstacle positions to match different skill levels. The included carry bag makes the set convenient for backyards, parks, camping trips and outdoor gatherings.
