The Roadiebase is Zempire's first fully-inflatable shelter, and this handy add-on creates a weatherproof connection to expand your lounging, kitchen or dining space! The weather-tight seal connects your shelter to the Zempire Delta Force V2 or Fortress V2 Canvas Air Tent (sold separately). It zips on easily, with two-way zipper heads that feature glow zip pullers, so you can find it in the dark.
