We Tested the Thule Interstate: Weather-Tough Cargo Bag

After three weekend trips in varying weather conditions, we’re impressed with the Thule Interstate Rooftop Cargo Carrier Bag. This soft-sided carrier proved remarkably resilient during our unexpected encounter with a thunderstorm in the mountains. Despite heavy rainfall, our luggage remained completely dry thanks to the weatherproof material and sealed seams.

Installation was straightforward, taking us under 10 minutes to secure to our crossbars. The bag’s 16 cubic feet capacity comfortably held luggage for our family of four, freeing up valuable interior space. We particularly appreciated the wide U-shaped opening that made packing and accessing gear simple.

While not as aerodynamic as hard-shell carriers, we noticed only minimal noise at highway speeds. At $269.95, it’s a solid investment for occasional travelers who need extra space without committing to a permanent rooftop fixture.
