Sailnovo Rooftop Cargo Carrier 21 Cu Ft Waterproof Soft-Shell Roof Bag — Reinforced Straps & Anti-Slip Mat

Planning a road trip, family move, or extended camping weekend? This Sailnovo rooftop cargo carrier adds generous, weather-resistant space without permanent roof racks. Made from military-grade PVC with sealed seams and an extended rain curtain, it keeps luggage dry and resists tears while folding away into a compact storage bag when not in use.

How much gear fits in the 21 cubic foot Sailnovo roof bag?

The carrier holds luggage for roughly 5–8 people depending on packing style and item size. Typical loads include multiple suitcases and camping equipment, and the bag compresses around soft items for efficient use.

• Capacity: 21 cubic feet—fits up to four medium suitcases plus sleeping bags and tents.
• Best for mixed loads: soft gear fills voids for compact packing.
• Compresses and folds into the supplied storage bag when empty.

Is the Sailnovo rooftop bag waterproof and durable enough for bad weather?

The exterior uses waterproof PVC with reinforced seams and an extended rain curtain to reduce water entry. Tear-resistant construction and military-grade materials improve longevity against abrasion and road conditions.

• Waterproof PVC shell resists rain and splashes.
• Reinforced seams and rain curtain provide extra protection from leakage.
• Durable fabric and design minimize tearing and wear on long trips.

How secure is the cargo carrier during travel and how does it attach?

Sailnovo includes ten heavy-duty reinforced tie-down straps, an anti-slip mat, and six door hooks to fasten the bag to vehicles with or without roof racks. An included luggage lock helps deter theft while straps and mat reduce shifting and surface scratches.

• 10 reinforced straps plus 6 door hooks for quick, tight installation.
• Anti-slip mat prevents sliding and protects the vehicle roof finish.
• Included luggage lock offers basic theft deterrence; always secure straps per instructions.

Will this fit my vehicle and how easy is it to install?

The Sailnovo carrier is designed for universal fit on cars, SUVs, hatchbacks, station wagons, and many pickups, with or without crossbars. Setup takes minutes: place the anti-slip mat, position the bag, run straps under doors or over crossbars, and tighten. Note: not suited for vehicles with sliding doors.

• Universal compatibility: works with bare roofs, crossbars, and side rails.
• Quick setup: strap-and-hook system requires no special tools.
• Compact storage bag included for off-season or when empty.
