ARB Rooftop Tents integrate an updated design with new materials for better strength, rigidity and water resistance. Manufactured from high-quality poly/cotton fabric and incorporating an Oxford polyester flysheet, rooftop tents are easily mounted to ARB?s purpose-designed roof rack, or suitably load-rated roof bars. A retractable aluminum ladder makes getting into bed a trouble-free event. Super Strong 1 inch Anodized aluminum poles improve strength and provide corrosion resistance properties, while a high-density 2.5 inch foam mattress (with removable cover) ensures you?ll sleep soundly. And don?t worry about the bed bugs biting, ARB Rooftop Tents come with insect screened windows and doors.
