The beginner slacklining kit: amazing for one kid, tricky for a crowd

This slacklining kit is amazing for a kid who wants a physical challenge — the kind who will practice the same move fifty times until they nail it. The training line and tree protectors are both thoughtful inclusions that make setup easier and prevent damage to the trees. But it’s less amazing as a party activity unless everyone’s comfortable taking turns and nobody’s in a hurry. Slacklining is a solo focus activity, so one kid uses it while the others watch or play something else. Great for the right kid, just know what you’re getting into.
