The Eureka Tetragon 3 is a 1 room tent that will sleep up to 3 people. The double-coated StormShield polyester fly and the polyester bathtub floor combine to provide excellent weather protection. It has 1 door and 2 windows for great views and wonderful ventilation. The shockcorded fiberglass frame is reliable and easy to set up. The hooded fly over the front and rear door windows allows you to leave the window partially open for even more ventilation even in rain. Large mesh screens on either side provide even more ventilation and comfort.
