If you are looking for Sailnovo car rooftop cargo carrier alternatives, you have come to the right place. The Sailnovo 21 cu ft Soft Roof Bag is a waterproof soft-shell carrier that mounts with tie-down straps. It offers 21 cubic feet of capacity and weighs 8.16 pounds, making it a lightweight, no-fuss option for cars without a roof rack.
The alternatives on this list were chosen because their specs overlap with the original. Some offer the same 21 cubic feet capacity but add features like a combination lock or a different shape. Others provide larger capacities, such as 30 or 40 cubic feet, for drivers who need more space. A few models are heavier or wider, which may suit larger vehicles better. Whether you want a lock for security, a bigger size, or a different brand, these picks give you practical options based on published specifications.
How each alternative compares
MeeFar 21 cu ft Waterproof Roof Bag
The MeeFar 21 cu ft Waterproof Roof Bag matches the Sailnovo’s 21 cubic foot capacity but adds a combination lock for security and is described as 100% waterproof. It is heavier at 10.7 pounds versus 8.16 pounds, and its dimensions are larger: 47 inches long, 35 inches wide, and 21 inches high compared to the Sailnovo’s 9.84 by 7.09 by 13.8 inches. The MeeFar requires a roof rack or crossbars, while the Sailnovo uses tie-down straps and can mount on bare roofs. Choose the MeeFar if you want lockable, fully weatherproof storage and have a roof rack. The Sailnovo is lighter and more flexible for vehicles without a rack.
The Asinking 21 cu ft Soft-Shell Roof Bag also offers 21 cubic feet of capacity and includes a combination lock, which the Sailnovo lacks. It is longer (52 inches) and wider (40 inches) than the Sailnovo’s 9.84 by 7.09 inches, and heavier at 9.48 pounds versus 8.16 pounds. The Asinking is designed for roof-mount installation but does not specify tie-down strap mounting like the Sailnovo. Both are waterproof soft shells. Pick the Asinking if you want a lock for security and have a larger roof area. Stick with the Sailnovo if you need a more compact, lighter bag that mounts with simple straps on any roof.
Rooftop Ranger 21 cu ft Soft Shell Cargo Carrier
The Rooftop Ranger 21 cu ft Soft Shell Cargo Carrier matches the Sailnovo’s 21 cubic foot capacity and soft-shell waterproof design. It adds a lock and an anti-slip mat, which the Sailnovo does not include. The Rooftop Ranger is larger: 54 inches long, 42 inches wide, and 17 inches high versus the Sailnovo’s 9.84 by 7.09 by 13.8 inches. It weighs 8.5 pounds, slightly more than the Sailnovo’s 8.16 pounds. Both use a roof mount, but the Rooftop Ranger is better suited for vehicles with a larger roof footprint. Choose it if you want extra security and slip protection. The Sailnovo is more compact and lighter for smaller roofs.
MCBD 40 cu ft Soft-Shell Roof Bag
The MCBD 40 cu ft Soft-Shell Roof Bag offers nearly double the capacity of the Sailnovo’s 21 cubic feet, making it the largest option here. It is designed for cars and SUVs, while the Sailnovo is for cars only. The MCBD weighs 16.3 pounds, almost twice the Sailnovo’s 8.16 pounds. Its dimensions are not fully listed, but it is significantly bulkier. Both are waterproof soft shells with roof-mount installation. The MCBD is better for SUV owners who need maximum cargo space for bulky items. The Sailnovo is lighter, more compact, and easier to handle for standard car roofs.
The FIVKLEMNZ 30 Cubic Feet Roof Bag provides 30 cubic feet of capacity, 9 cubic feet more than the Sailnovo. It is larger: 60 inches long, 60 inches wide, and 20 inches high versus the Sailnovo’s 9.84 by 7.09 by 13.8 inches. It weighs 12 pounds, compared to 8.16 pounds. Both are waterproof soft shells that mount on car roofs without requiring a rack. The FIVKLEMNZ is a better choice if you need extra space for longer trips. The Sailnovo is smaller, lighter, and easier to store when not in use.
The RoofPax 19 cu ft Polyester Roof Bag offers 19 cubic feet of capacity, 2 cubic feet less than the Sailnovo. It is larger in footprint: 47.2 inches long, 35.4 inches wide, and 19.8 inches high versus the Sailnovo’s 9.84 by 7.09 by 13.8 inches. The RoofPax is heavier at 12.4 pounds versus 8.16 pounds. Both are waterproof soft shells that mount on roofs with or without racks. The RoofPax comes in multiple colors (black, orange, grey), while the Sailnovo is only black. Choose the RoofPax if you want a slightly smaller capacity but a wider, lower-profile bag. The Sailnovo is more compact and lighter.
