DUMOS Car Roof Bag Cargo Carrier 15 cu ft Waterproof Soft‑Shell — Rack‑Free Expandable Storage

The DUMOS Car Roof Bag is a 15-cubic-foot, fully waterproof rooftop cargo carrier that expands vehicle storage without permanent racks and keeps gear secure in any weather.

Whether you're planning a weekend camping trip, a family road journey, or simply need extra space for moving boxes, this rooftop bag adds significant capacity while folding away when not in use. Constructed from heavy-duty PVC with reinforced seams and multiple security features, it’s designed to protect luggage from rain, snow, and road grime. The carrier installs quickly on sedans, SUVs, trucks, and hatchbacks—rack or no rack—and includes an anti-slip mat and locking hardware to stabilize and secure your load.

How much luggage can this rooftop carrier actually hold?

The DUMOS roof bag offers 15 cubic feet of storage, enough for several suitcases, a couple of sleeping bags, or camping gear. It’s a practical capacity increase for family trips or moving small loads without towing a trailer.

• 15 cu ft volume—fits multiple medium suitcases or large duffel bags
• Suits camping equipment like tents, pads, and sleeping bags
• Compressible soft-shell design lets you pack oddly shaped items

Will it keep belongings dry and protected in bad weather?

The bag is made from tearproof, waterproof PVC with sealed seams to repel water, snow, and road spray. A snug zipper cover and included straps add an extra barrier against moisture and dust, so gear stays drier than with open rooftop loads.

• 100% waterproof outer shell and sealed seams
• Zipper flap and reinforced closure reduce water penetration
• Durable material resists rips and punctures from travel wear

How does it attach and stay secure while driving?

Installation is straightforward: position the bag on your roof, run the reinforced straps through doors or around crossbars, and tighten. Anti-slip matting and included door hooks, reinforcement strips, and a combination lock enhance stability and theft resistance.

• Multiple reinforced straps and door hooks for secure fastening
• Anti-slip mat prevents movement and protects vehicle paint
• Combination lock and reinforcement strips increase security

Is this roof bag easy to store and compatible with my vehicle?

The flexible, soft-shell construction collapses into the included storage bag when not in use and fits most vehicles—sedans, hatchbacks, SUVs, trucks, and crossovers—with or without roof racks. Setup takes only minutes so it’s convenient for occasional or seasonal use.

• Folds compactly into the supplied storage pouch for off-season storage
• Universal fit works with bare roofs, crossbars, and side rails
• Quick installation and removal—no tools required for most vehicles

Who this is for: Drivers who need a reliable, temporary way to expand cargo space—families on road trips, campers, students moving between residences, or anyone avoiding a trailer. If you want a weatherproof, packable rooftop solution that protects gear and installs fast, the DUMOS 15 Cu Ft rooftop cargo bag is tailored to those needs without permanent roof modifications.
