MIDABAO 20 Cu Ft Waterproof Rooftop Cargo Bag — PVC-Coated, Coated Zippers & Anti-Slip Mat

The MIDABAO 20 cubic feet waterproof rooftop cargo bag is a high-capacity, PVC-coated soft carrier that adds secure, weatherproof storage to almost any vehicle roof.

This rooftop carrier expands your vehicle’s luggage room without needing hard racks or permanent mounts. Sized at 51.1" x 39" x 17" and holding up to 20 cubic feet, it’s built with a fully coated PVC exterior and interior, heavy-duty straps, and coated zippers to keep gear dry and stable on long trips. The design collapses for compact storage and includes an anti-slip mat to protect both the bag and your car’s finish.

How much gear will the MIDABAO roof bag actually hold?

This carrier provides 20 cubic feet of cargo space, suitable for several suitcases, camping gear, or bulky items that won’t fit inside your cabin. The rectangular footprint and 17" height make it easier to pack soft items and maximize usable volume compared with narrower bags.

• Overall dimensions: 51.1" x 39" x 17" for clear packing expectations.
• 20 cubic feet capacity — room for luggage, sleeping bags, or groceries.
• Soft-sided shape conforms around irregular loads for efficient use.

Will this rooftop bag stay dry in heavy rain?

Yes — the MIDABAO bag is coated with PVC both inside and out, offering waterproof protection rather than mere water resistance. Coated zippers reduce water entry points, and the tightly welded seams help keep contents dry even in prolonged wet conditions.

• Full inner and outer PVC coating for stronger water protection than standard fabrics.
• Coated, weather-resistant zippers to limit seepage along closures.
• Welded seams and durable shell reduce risk of leaks during storms.

How does it attach to my car — do I need roof racks?

Installation is straightforward and works with or without factory roof racks. The carrier uses six shorter straps plus two long straps to anchor to door frames or crossbars, and the included anti-slip mat prevents shifting and protects paintwork.

• Six wide fastening straps and two extra-long straps for secure mounting.
• Compatible with vehicles that have roof racks or only bare roof rails.
• Anti-slip mat included to reduce movement and protect your vehicle’s finish.

How easy is the bag to store and reuse?

Because the MIDABAO carrier is soft and malleable rather than reinforced with rigid liners, it folds down compactly when not in use. A storage bag is included so the unit tucks into trunks or closets, ready to deploy on your next trip.

• Soft construction packs flat for easy storage in trunk or garage.
• Storage bag included for neat organization between trips.
• Quick-attach straps let you mount or remove the bag in minutes.

Who is this for: Travelers, weekend campers, families, and anyone who needs reliable extra cargo room without investing in a hard rooftop box. It suits drivers who want a weatherproof solution that works across multiple vehicles, provides roomy capacity, and stows away compactly when not in use. If you prioritize waterproofing, flexible storage, and simple installation, the MIDABAO 20 cubic foot rooftop carrier is designed to meet those needs.
