#1 for Safety, Convenience, Performance - This is not just a car top carrier for vehicles with racks, it's also the perfect car roof bag without rack solution. Justin Case is the only extra large rooftop car carrier that uses four safety door hooks, instead of straps inside the car. Inside car straps can interfere with airbag function, damage your window and door seals, tear fabric upholstery, and are illegal in some jurisdictions. Our rooftop bag is safer and better for your car. Extra Large Car Top Bag - Enjoy the convenience of a full 19 cu. ft. of rooftop storage space, most other car roof cargo carriers are smaller and don't have the room to fit everything you need. The Justin Case Rooftop Cargo Carrier Bag is much more than a luggage box, a luggage carrier, or a standard car rack storage system: this is an advanced design roofbag that's simple to use, spacious, durable, waterproof, and designed to tackle any travel challenge. Ultra-Durable Construction - This car roof bag is made from high quality, 100% waterproof 600D PVC fabric, with ultra-durable dual-seam welding technology to eliminate rips, tears, and wear under rugged conditions. Protective mat is built in. Other car roof rack carriers and rooftop carrier storage solutions don't have anywhere near the same level of quality in design and manufacture as the Justin Case Rooftop Cargo Carrier Bag, check carefully before you buy. Advanced Design - We know the performance you need from an overhead car storage bag, that's why this is the ultimate car travel and camping accessory. Advanced design, military quality components include four high strength safety hooks, side release buckles, SBS zippers with large pulls, three double strap covers, and eight velcro fasteners help keep everything you store in our car top luggage carrier safe. This roof luggage carrier is designed for high performance and long life. Risk-Free Purchase - Our customers' satisfaction, confidence, and trust in our products is our #1 priority.
