Looking Beyond the RoofPax Waterproof 19 Cubic Feet? 6 Alternatives Worth a Look

How each alternative compares

MeeFar 21 cu ft Waterproof Roof Bag

The MeeFar 21 cu ft Waterproof Roof Bag offers 2 cubic feet more capacity than the RoofPax 19 cu ft bag, with a slightly wider and taller profile (35 x 21 inches vs 35.4 x 19.8 inches). It weighs 10.7 pounds, about 1.7 pounds lighter. The MeeFar includes a combination lock for added security, which the RoofPax does not. Its waterproofing and universal fit are comparable. However, the RoofPax uses a patented 4-door hook strap system for rackless mounting, while the MeeFar relies on a standard strap kit. If you want a bit more volume and a built-in lock, and don't mind a different mounting setup, the MeeFar is a strong alternative.

The FIVKLEMNZ 30 Cubic Feet Roof Bag provides 11 cubic feet more capacity than the RoofPax 19 cu ft bag, making it the largest soft bag on this list. Its dimensions are 60 x 60 x 20 inches, significantly longer and wider, so it requires more roof space. It weighs 12 pounds, slightly less than the RoofPax's 12.4 pounds. The FIVKLEMNZ includes a complete mounting kit for rackless installation, but it lacks the RoofPax's patented door-hook straps. If you need maximum cargo volume and have a large roof area, the FIVKLEMNZ is the better choice, though the RoofPax offers a more compact footprint and a dedicated hook system.

Sailnovo 21 cu ft Soft Roof Bag

The Sailnovo 21 Cubic Feet Roof Bag is a budget-friendly alternative to the RoofPax 19 cu ft bag. It offers 2 extra cubic feet of capacity but has smaller listed dimensions (9.84 x 7.09 x 13.8 inches), which likely refer to the folded size. It weighs only 8.16 pounds, over 4 pounds lighter than the RoofPax's 12.4 pounds, making it easier to handle. The Sailnovo uses simple strap installation and is waterproof, but it lacks the RoofPax's patented door-hook system and lifetime zipper warranty. If you are looking for a lighter, lower-cost soft bag for occasional use, the Sailnovo is a practical option, but the RoofPax offers more robust mounting and warranty coverage.

The Asinking 21 cu ft Soft-Shell Roof Bag provides 2 cubic feet more capacity than the RoofPax 19 cu ft bag, with a longer and wider footprint (52 x 40 x 18 inches vs 47.2 x 35.4 x 19.8 inches). It weighs 9.48 pounds, about 3 pounds lighter. The Asinking includes a lock for security, a feature the RoofPax does not offer. Both bags are waterproof and can mount on vehicles without roof racks. The Asinking uses a standard strap kit, while the RoofPax uses a patented 4-door hook system. If you want a lock and a slightly larger, lighter bag, the Asinking is a solid alternative, though the RoofPax's hook straps may feel more secure to some users.

The Kingfun 20 cu ft Roof Bag offers 1 cubic foot more capacity than the RoofPax 19 cu ft bag. Its exact dimensions are not listed, but it is designed for universal fit and rackless installation. The Kingfun emphasizes highway stability and waterproofing, similar to the RoofPax. However, the RoofPax includes a patented 4-door hook strap system and a lifetime zipper warranty, which the Kingfun does not specify. If you want a slightly larger bag with a focus on stability at speed, the Kingfun is a good option, but the RoofPax provides more detailed mounting hardware and warranty coverage.

The BagMate 23 cu ft Roof Bag offers 4 cubic feet more capacity than the RoofPax 19 cu ft bag, with dimensions of 55 x 44.9 x 19.5 inches, making it longer and wider. It weighs 13.1 pounds, slightly heavier than the RoofPax's 12.4 pounds. The BagMate is made from 840D PVC, while the RoofPax uses polyester. Both are waterproof and mount without roof racks. The BagMate is designed for SUVs and cars, while the RoofPax fits any vehicle. If you need more volume and prefer a PVC shell, the BagMate is a strong alternative, but the RoofPax's polyester build and door-hook system offer a different material and mounting approach.
