RoofPax XXL 28 cu ft Rooftop Cargo Bag — Waterproof with Patented Door-Hook Mount & Heavy-Duty Straps

When you need dependable extra cargo space for road trips, family vacations, or moving day, the RoofPax XXL provides 28 cubic feet of interior volume in a durable, weather-ready pack. Built for SUVs and larger vehicles, this rooftop bag uses reinforced materials, dual zippers, and a patented mounting system that keeps straps outside the passenger cabin so installation is safer and simpler.

How does the patented mounting system keep installation safer?

The RoofPax patented mounting system uses four external door-hook straps that clip over door frames instead of threading straps through the inside of the vehicle. This avoids pinched straps in car doors, reduces interior clutter, and provides a cleaner, faster setup.

• Four patented door hook straps included for no-inside-car installation
• Clips anchor outside the door frame for easier tightening and release
• Works on vehicles with or without roof racks, raised rails, or crossbars

Will this rooftop bag stand up to rain, wind, and long trips?

The bag is made with a water-repellent fabric, double-seam construction, and heavy-duty dual zippers to resist wet weather and road spray. Velcro zipper flaps and reinforced seams improve water resistance while rugged straps and buckles hold gear secure at highway speeds.

• Dual weatherproof zippers with Velcro flap protection
• Double-seam technology and water-repellent coating on fabric
• Heavy-duty buckles and straps rated for highway use

What fits in 28 cubic feet, and how do I pack it efficiently?

At 28 cu ft, the RoofPax XXL accommodates multiple suitcases, duffel bags, camping gear, or bulky items like a stroller or sleeping bags. Use soft bags and compression packs to maximize usable space and keep heavier items low and centered for balanced handling.

• Compatible with large suitcases, backpacks, and sports equipment
• Recommended packing: soft luggage, compression sacks, blankets
• Place heavier items near the center for stable driving dynamics

What accessories and warranties are included with the carrier?

The RoofPax package arrives complete with the patented door hook straps, ten heavy-duty tie-down straps, four extra hooks, a combination lock for the zippers, and a storage bag for easy transport when not in use. RoofPax also backs key components with long-term coverage.

• Included: 4 patented door-hook straps, 10 tie-down straps, and 4 hooks
• Combination lock and robust storage carry bag included
• Warranty: lifetime on zippers and five-year fabric durability coverage

Who is this for? The RoofPax XXL rooftop cargo carrier is designed for families, outdoor enthusiasts, and anyone needing substantial, weather-resistant extra space without modifying their vehicle. It’s ideal for SUVs, crossovers, and larger cars whether you have factory roof rails or a bare roof. If you want a safe, high-capacity travel bag that installs without interior straps and includes heavy-duty hardware plus strong warranty support, the RoofPax XXL is built for those long drives and unpredictable weather.
