They work as makeshift restrooms for campers, places to change into and out of bathing suits for swimmers, and dressing rooms for models being photographed on location. Plant aficionados use them as growing rooms and protection for plants sensitive to cold. Some work as outdoor shower stalls. Many literally pop open, so there’s not a lot of prep work necessary to set one up, and fold down into a flat package you can carry with one hand. Most have stake loops and sandbag flaps so that you can anchor the privacy tent to both soft and hard ground.
