RoofPax Rooftop Cargo Carrier Bag XXL 28 cu ft — Waterproof, Patented Door-Hook Mounting

RoofPax XXL is a 28 cubic-foot, fully waterproof rooftop cargo carrier bag engineered for secure, high-capacity car-top storage using patented door-hook mounting and heavy-duty straps.

Whether you’re loading a family vacation, camping gear, or bulky sports equipment, this RoofPax rooftop carrier gives you large-capacity storage that fits SUVs and larger vehicles with or without roof racks. Built with reinforced seams, dual zippers, and a water-repellent exterior, the carrier focuses on durability and practical installation so you can pack more without worrying about weather or insecure attachment.

How does the patented RoofPax mounting system improve safety?

The RoofPax system uses four patented door-hook straps that secure the bag from the outside of the vehicle rather than running straps through the car interior. This design reduces interior clutter, prevents strap slippage inside the cabin, and keeps tie-downs independent of passive interior anchors.

• Four patented external door hooks for stable anchoring
• Doesn't require running straps through doors or windows
• Works on vehicles with or without roof racks or raised rails
• Includes four heavy-duty straps and four additional hooks for redundancy

Is the RoofPax XXL truly waterproof for rainy or snowy trips?

The RoofPax bag combines a water-repellent outer coating with double-seam construction and dual weatherproof zippers to keep contents dry in most wet conditions. While designed to resist rain, snow, and road spray, always check zipper closures and straps before long trips for optimal protection.

• Durable water-repellent fabric plus double-seam reinforcement
• Dual zippers with an overlapping weather flap for added sealing
• Velcro strap restraints help keep zipper flaps in place
• Recommended for typical travel weather; avoid prolonged submersion

How much gear fits inside and how do I pack it efficiently?

At 28 cubic feet, the RoofPax XXL accommodates luggage for several passengers or large items like sleeping bags, tents, and bulky clothing. Pack soft items and use compression bags to maximize space, placing heavier items low and centered to preserve vehicle stability.

• 28 cu ft capacity suitable for family trips and outdoor gear
• Use compression sacks for clothing and bedding to save room
• Distribute weight evenly and keep heavy items near the middle
• Includes a storage bag to stow the RoofPax when not in use

RoofPax backs the product with a lifetime zipper warranty and a five-year fabric warranty, plus 24/7 customer support for installation or service questions.
