DUMOS Car Roof Bag 15 Cu Ft Waterproof Cargo Carrier — Heavy-Duty PVC, Anti-Slip Mat

DUMOS Car Roof Bag is a 15 cubic foot, 100% waterproof rooftop cargo carrier designed to expand vehicle storage and protect luggage from rain, snow, and road wear.

Whether you're heading out for a weekend camping trip, moving boxes, or taking extra luggage on a family vacation, the DUMOS roof bag gives you extra cargo capacity without a permanent rack. Built from heavy-duty PVC with sealed seams and reinforced hardware, it folds away into a compact storage pouch when not in use. The carrier is engineered to work with vehicles that have crossbars, side rails, roof baskets or even bare roofs, so you can add space quickly and remove it when the trip is over.

How much gear will the 15 cubic feet actually hold?

The 15 cu ft capacity accommodates several soft suitcases, sleeping bags, or camping equipment—enough for a small family or a couple packing for a multi-day trip. Its flexible soft-shell design allows you to squeeze extra items inside while keeping them secure.

• Fits multiple carry-on suitcases or 2–3 large duffel bags
• Room for tents, sleeping bags, jackets and pillows
• Flexible interior adapts to different shapes for efficient packing

Will it stay put at highway speeds and in bad weather?

DUMOS uses reinforced straps, door hooks, and an anti-slip mat to keep the bag stable and reduce movement in transit. The combination lock and reinforcement strips add security while sealed seams and heavy PVC keep water and road spray out.

• Reinforced tie-down straps with quick-adjust buckles for tight fastening
• Anti-slip mat protects vehicle paint and prevents sliding
• Combination lock and security hooks deter theft and accidental opening

How easy is installation and storage when not in use?

Setup takes only minutes: lay the anti-slip mat, position the bag on the roof, thread straps through doors or around crossbars, then tighten. After your trip the soft-shell bag folds into the included storage sack for compact, out-of-the-way storage.

• Quick-install design works with crossbars, rails, roof baskets, or bare roofs
• Folds down into the supplied storage bag to save space at home
• Lightweight construction allows one person to install or remove it

Will it damage my car's roof or interfere with daily driving?

The included anti-slip mat protects paint and reduces friction between the bag and roof, while properly routed straps avoid door seals. When installed correctly the bag minimizes wind noise and does not obstruct visibility or safe driving.

• Anti-slip mat prevents paint scratches and distributes pressure
• Low-profile shape designed to reduce wind resistance and noise
• Door-hook routing protects rubber seals and interior trim from strap wear

Who this is for: The DUMOS 15 Cu Ft roof bag is ideal for weekend adventurers, campers, small families, and anyone who needs temporary, weatherproof cargo capacity without installing permanent roof racks. It suits drivers of sedans, hatchbacks, SUVs, trucks, and crossovers who want a portable, secure way to carry extra gear for road trips, outdoor weekends, or home moves.
