Transparent PVC walls are the entire idea here, turning a shelter into something closer to a window on all sides. Where a fabric tent closes the view off the moment the door zips, this one keeps the surroundings visible from every wall, and a clear skylight overhead opens the sky, so the stars stay in view from inside after dark. The structure pops up rather than being threaded pole by pole, so it goes from bag to standing in one motion and collapses the same way, packing into a round carrying bag 3 ft across. Set up, it measures 9.5 ft by 9.5 ft with 6.2 ft of headroom, room enough for 5 to 6 people to sit inside without crowding the walls. PVC does something a nylon shell cannot: it is cold-resistant and heat-retaining, holding warmth inside rather than letting it pass straight through the fabric, which is what makes a clear shelter usable outside of high summer. Ventilation is handled without breaking the transparency, through two doors on smooth dual-sided zippers that can be worked from inside or out, and two side windows that keep air moving so the interior does not fog or go stale. Anchoring comes from stakes, wind ropes and sandbags, all of which matter more on a lightweight dome with large flat wall surfaces. The frame is fiberglass, the shell is PVC, total weight is 16 lb, and assembly is required.
