The Rainbow Wet/Dry Combo is not your average Combo. It measures 27.5ft x 17ft x 15ft. This Combo is always a hit. It comes with a basketball goal inside then leads to a slide that can have a backstop or a pool at the bottom. The Rainbow Combo takes 1 blower and needs to be within 100ft of a dedicated 20amp outlet. A soaker hose is mounted onto slide and will need an additional hose to connect to your water source.
