This is the prototype 2‑storey tent I tested on this trip: XenoNest, The Two-Story Air House. I was honestly impressed by how well designed it is—no tools, no screws, and the second level tightens up cleanly with a simple peg. If you want to see this tent on the market, supporting the Kickstarter is the way to do it.
You'll be taken to Kickstarter to complete your purchase.
