ENHANCED DURABILITY; 100% WATERPROOF: While other rooftop carrier bags let in water through the zipper or quickly wear out, we've designed ours using triple-layer waterproof tarpaulin that weathers rain, wind, grit, or heat, and fitted it with a zipper flap that helps keep your items 100% dry. STORE IT ALL: Going camping or on a road tip? This 44" (L) X 34" (W) X 17" (H) car roof bag packs 15 cubic feet (425 liters) of space to give you ample storage room, And unlike a hard car top carrier that struggles to fit odd-shaped items, ours has soft sides that flex to accommodate them. INSTALLATION MADE SIMPLE: You'll be hitting the road in no time. We've included 8 reinforced straps with heavy-duty buckles to easily and securely install the waterproof roof top bag. Whatever your car, this roofbag car top carrier will fit as long as it has a roof rack. THOUGHTFUL DESIGN: No dealing with bulky roof rack bags. Ours compactly folds down to the size of a tablet, allowing you to store it in the trunk of your car or inside the glove compartment with space-friendly ease. And maintaining it couldn't be simpler: all it needs is an occasional wipe. LIFETIME WARRANTY: We've backed our soft shell car topper bag with an iron-clad lifetime warranty to give you total peace of mind and the best bang for your buck. Go ahead, add instant cargo space to your car and cruise with confidence completely risk-free!
