This water slide is a really big Dill! The matching sled helps every slider reach top speeds for ultimate fun. At 18 feet long, if you've got a big yard, you're basically required to open it up to all the neighborhood kids for some epic memories (hero-for-a-day status: achieved). There's no inflation required, just unroll, add water, and go crazy. It has built-in cascading sprinklers for ultimate slidage. Perfect for parties and heat waves!
