This is the Ogawa Tierra 5-EX half inner tent. Half inner tent for Tierra 5-EX (for 2-3 people) Allows for a wide L-shaped living space. Features openings on all four sides that can be made into mesh, providing good ventilation and easy access. The bottom is completely waterproof, using safe PVC material. I used it once as an inner tent for a Lodge Shelter, but I am selling it because I have sold the Lodge Shelter. Includes a memo on how to set it up, written by a store clerk at an Ogawa store.
