Why this product
Why the WeatherTech RackSack Rooftop Cargo Bag?
WeatherTech's RackSack is a 7 lb waterproof rooftop bag with heavy-duty zippers — built to the same quality standard as their famous floor mats. It works with crossbars for a secure mount. The downside? Heavier than competing bags from Thule and Yakima at similar volume, no security features, and the WeatherTech brand premium means you're paying more for comparable performance.
