FIVKLEMNZ 30 Cubic Foot Waterproof Rooftop Cargo Bag — 60x43x20 in, Reinforced Straps & Anti-Slip Mat

The FIVKLEMNZ 30 cubic-foot rooftop cargo carrier is a heavy-duty, fully waterproof roof bag that adds substantial exterior luggage space for cars, SUVs, and trucks with or without roof racks.

Whether you're planning a long road trip, camping weekend, or need extra room for holiday luggage, this soft-shell roof bag offers a simple way to expand vehicle capacity without permanent hardware. Constructed from reinforced 840D PVC with welded seams, it balances weather resistance with flexible storage and ships with straps, door hooks, an anti-slip mat and a luggage lock for secure transport.

How much gear can the 30 cubic-foot bag hold?

This rooftop carrier measures approximately 60 x 43 x 20 inches and provides about 30 cubic feet of storage—enough for several suitcases, camping equipment, or bulky sports gear. The roomy interior helps free up cabin space while keeping items dry and contained on long drives.

• Fits 7–9 medium suitcases, tents, sleeping bags, or bulky outerwear.
• Dimensions: 60 x 43 x 20 inches for easy packing planning.
• Holds widely varying shapes thanks to the flexible soft-shell design.

Is it weatherproof and durable enough for long drives?

The bag uses 840D PVC fabric with high-frequency welded seams and a double-layered waterproof cover to block rain, snow and road spray. The reinforced construction is designed for frequent travel, resisting abrasion while protecting contents from moisture.

• Waterproof material plus welded seams prevent leaks in heavy rain.
• Double-layer cover adds extra protection against wind-driven water.
• Heavy-duty fabric resists tears and road wear on extended trips.

How does the bag attach and stay secure at highway speeds?

FIVKLEMNZ includes a reinforced fastening system: 10 heavy straps and 6 door hooks work together with an anti-slip mat to keep the bag stable on diverse roofs. These components reduce shifting and protect the vehicle finish while the included luggage lock gives an added layer of security for unattended stops.

• Ten reinforced straps distribute load and tighten the bag to the vehicle.
• Six door hooks allow installation on vehicles without crossbars or rails.
• Anti-slip mat protects paint and reduces lateral movement during travel.

Will it fit my car if I don’t have a roof rack?

The design accommodates vehicles with or without roof racks—side rails, crossbars or plain roof surfaces. The straps and door-hook system enable quick setup on most sedans, hatchbacks, SUVs and small trucks, and the soft bag stores compactly when not in use.

• Works on cars, SUVs, vans and trucks with or without racks.
• Quick-install straps and hooks allow easy attachment in minutes.
• Collapses into a storage bag for space-saving off-season storage.

Who is this for: The FIVKLEMNZ 30 cubic-foot rooftop cargo carrier is ideal for families, outdoor enthusiasts and travelers who need a weatherproof, temporary roof storage solution that won’t require permanent roof hardware. Choose this size for larger vehicles or when you regularly carry bulky gear—opt for smaller sizes if you drive a compact car. Every kit includes an anti-slip mat, reinforced straps, door hooks, a luggage lock and a storage bag so you have a complete setup for reliable road use.
