The Chaos is a one continuous pole design, free standing tent that is enhanced with 2 doors for easy entry and 2 vestibules for gear storage and extra weather protection. Extra large #8 zippers make opening and closing the doors and vestibules a breeze. The Chaos has 7000 series aluminum poles that are strong and lightweight. Assembly is really easy with the tent clips that just snap in place over the poles. With a factory sealed fly and floor seams, you're sure to stay dry in rainy weather. The polyester fly and floor are urethane coated, factory sealed seams for maximum weatherproofness. The mesh roof vents increase ventilation and improves star gazing.
