Thule's most weather-resistant cargo bag ever—'nuff said.

When you throw all of your road-trip extras and essentials in most cargo bags, you either hope for good weather or you head to the driest national parks. The Thule Interstate Cargo Bag is a game changer, though. It's Thule's most weather-resistant cargo bag, which has been IP-test-verified for water resistance and boasts sealed seams and a generous storm flap over the three-sided zipper. It's also ideal for those that need lots of extra cargo space for their next adventure, offering 16 cubic feet of storage.

Twin compression straps keep cargo securely positioned, even in a downpour with wicked winds, and the padded base protects your vehicle's finish from abrasion when you are taking this bag on and off. The Interstate fits Thule rack systems, round bars and most factory racks via heavy-duty, double-stitched webbing straps (included). When not in use, the Interstate folds down easily for compact storage—a big advantage over cargo boxes. The Quest attaches to aftermarket and factory installed roof racks and folds down into its included stuff sack for handy storage under a seat when it isn't in use. Heavy-duty molded handles let you throw the Quest around with ease once you reach your destination.
