Asinking Car Rooftop Cargo Bag 21 cu ft Waterproof Roof Carrier with Anti-Slip Mat & 10 Reinforced Straps

The Asinking 21 cubic-foot rooftop cargo carrier is a heavy-duty, fully waterproof soft-shell roof bag that expands vehicle storage for road trips, camping, and family travel.

When your car’s trunk fills up, a reliable rooftop bag adds flexible, weatherproof storage without the cost or permanence of a hard box. This Asinking roof top bag combines 900D PVC tarpaulin, reinforced seams, and extra security features so you can carry bulky gear—tents, suitcases, sleeping bags, even golf clubs—on nearly any car, SUV, or wagon.

How durable is this rooftop cargo bag against rain, wind, and rough handling?

The fabric is 100% waterproof 900D PVC with seams fused using high-frequency welding for improved tear resistance and long-term durability. A soft-shell design reduces blow-by in wind and absorbs impacts better than thin vinyl bags.

• Waterproof 900D PVC tarpaulin resists soaking and pooling.
• High-frequency welded seams prevent seam failure under strain.
• Soft, reinforced construction tolerates compressible loads and bumps.
• Includes a non-slip rubber mat to protect roof finish and prevent sliding.

Will it fit my car — with or without roof rails?

This Asinking carrier is designed as a universal fit for most cars, SUVs, and crossovers and works whether your vehicle has roof rails, cross bars, or no rack at all. The included straps and hooks secure directly to door frames or around rails to hold the bag steady while driving.

• Dimensions: 52" L x 40" W x 18" H (21 cu ft) fits 4–6 people’s luggage.
• Ten reinforced straps distribute tension for stable mounting.
• Six door hooks allow attachment when no roof rack is present.
• Foldable for compact storage when not in use.

What security and convenience features help protect my gear?

Security was built into the design: the zipper can be locked with the included combination lock to deter casual theft, while the extra lock keeps the zipper from sliding open during stops. For convenience, the bag comes with a storage sack and a rubber mat so setup and breakdown are quick and roof-safe.

• Included combination luggage lock secures the zipper pulls together.
• Anti-slip rubber mat protects paint and reduces movement.
• Storage bag keeps the carrier compact when folded.
• Ten straps and six hooks secure to multiple vehicle anchor points.

How much gear can it actually carry on a family trip?

At 21 cubic feet, the bag holds a substantial amount of soft and semi-rigid items—think several duffels, a tent and sleeping bags, a couple of suitcases, or larger single items like golf bags or compact folding chairs. Because the shell is flexible, you can compress odd-shaped items to maximize space.

• Capacity suitable for gear for 4–6 travelers.
• Soft-shell adapts to odd-shaped and compressible items.
• Load distribution aided by ten reinforced straps to reduce stress on seams.

Who is this for? The Asinking rooftop cargo bag suits families, weekend campers, and travelers who need extra, temporary storage without mounting hardware. It's also a practical choice for renters and drivers of multiple vehicles because it installs and removes quickly, stores compactly, and offers weatherproof protection and added security when you’re on the road.
