Texsport Hilo Hut Privacy Shelter is a necessity for camping. This 4'x 4'privacy shelter can be used as a toilet shelter or a changing room.
With included stakes and a carry bag it is easily portable. I would advise though to purchase separate thicker/longer stakes. When a good amount of wind comes by it can easily blow over with the ones provided.
At around $40 this should be on the top of all camping lists along with tents and sleeping bags.
