The Thule Outbound 868 Roof Cargo Bag is the perfect travel companion, whether you're headed out for the weekend or a coast-to-coast odyssey. This soft-sided, weather-resistant rooftop accessory is spacious enough to carry your entire family's vacation gear, and tough enough to protect it out there on the open road. The laminate material is rugged and highly weather-resistant, and the padded base protects your car's finish. Heavy-duty, double-stitched straps attach the cargo bag to your roof-rack crossbars or raised factory rails. Twin compression straps keep the load stable, minimize abrasion and noise, and improve aerodynamics. When you've gotten back home, the Interstate folds down for compact storage.
