Kids can elevate their play every time they go outdoors! The colorful prism design of this 50-foot slackline adds a fun twist to the classic kit while improving balance and strengthening core muscles. Attach the slackline to two healthy trees, 50 feet or less apart. Use the teaching line included for support with beginners until they build the balance, strength and confidence to use the slackline independently. Within minutes, kids will feel like they’re walking on air even though they’re never far from the ground. For ages 5 and up. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
