DUMOS Car Roof Bag Cargo Carrier — 20 Cu Ft Waterproof, Heavy-Duty & Foldable

DUMOS Car Roof Bag is a 100% waterproof, heavy-duty 20 cubic foot rooftop cargo carrier that fits most vehicles and protects extra luggage on road trips.

Need dependable extra storage for weekend getaways, moving boxes, or camping gear? The DUMOS 20 Cu Ft roof bag expands your vehicle’s cargo capacity without permanent racks, offering a weatherproof, tear-resistant solution that folds away when not in use. Built with reinforced straps, anti-slip matting, and sealed seams, it’s designed to keep belongings dry, secure, and stable on highways, ferry rides, and rural roads.

How does the DUMOS roof bag withstand rain, snow, and rough conditions?

The shell is made from heavy-duty PVC that’s fully waterproof and tearproof, and seams are sealed to block water intrusion. Weather-resistant construction helps prevent damp gear and soggy luggage even in prolonged exposure to rain or slush.

• 100% waterproof PVC outer material with reinforced seam sealing.
• Tearproof fabric resists abrasion from straps and roof contact.
• Foldable soft-shell design won’t trap water when packed away.

Will this cargo carrier fit my vehicle and how easy is installation?

DUMOS designed the bag for universal compatibility — it works on cars with crossbars, side rails, baskets, or bare roofs without racks. Setup is quick: unfold the bag, position it, route the reinforced straps and door hooks, and tighten; it packs down into the included storage bag for compact stowing.

• Fits sedans, SUVs, hatchbacks, trucks, and crossovers.
• Includes door hooks and adjustable reinforced straps for secure mounting.
• Folds into the supplied compact storage bag for easy carry.

How does the DUMOS bag keep cargo secure and prevent vehicle damage?

Security and stability combine through a non-slip underside, reinforced strap system, and included combination lock and security hooks. The anti-slip mat prevents sliding and scratches, while the reinforcement strips and lock reduce movement and deter opportunistic theft.

• Non-slip mat protects paint and keeps bags from shifting.
• Reinforced straps and door hooks add pulling strength in transit.
• Combination lock and security hooks provide extra theft deterrence.

How much can I carry and what accessories are included?

With 20 cubic feet of interior space, the bag accommodates several suitcases, sleeping bags, or camping supplies—ideal for family trips or moving small loads. The kit arrives with accessories to get you on the road quickly and store the unit compactly when not in use.

• 20 cu ft capacity holds multiple medium suitcases or bulky camping gear.
• Includes anti-slip mat, combination lock, security hooks, and reinforcement strips.
• Comes with a storage bag for compact packing between trips.

Who is this for? Drivers who need reliable, temporary roof storage without permanent racks will benefit most from the DUMOS roof bag: families heading on road trips, campers transporting tents and sleeping bags, small movers needing extra capacity, and anyone looking to protect cargo from wet weather while avoiding roof-mounted hard cases. If you want a portable, weatherproof, and easy-to-install rooftop solution that packs away when you don’t need it, this carrier is a practical choice.
