ARB Rooftop Tents integrate an updated design with new materials for better strength, rigidity and water resistance. Manufactured from high - quality polycotton fabric and incorporating an Oxford polyester flysheet, rooftop tents are easily mounted to ARBs 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 youll sleep soundly. And dont worry about the bed bugs biting, ARB Rooftop Tents come with insect screened windows and doors.
