10 Best Roof Cargo Boxes 2025 in the United States

The MeeFar Car Roof Bag XBEEK is designed for those looking for extra storage space during travel, especially useful for families or anyone needing to transport bulky items. With a generous capacity of 20 cubic feet, it can hold several suitcases or camping gear, making it an attractive option for road trips.

One of the standout features is its waterproof and tearproof construction made from 700D PVC tarpaulin, ensuring that your belongings stay dry even in bad weather. The easy installation process, complemented by an anti-slip mat and multiple securing straps, allows for a straightforward setup, whether your car has a roof rack or not.

Security is also prioritized, with a combination lock to secure the zippers and protect your items. This is a beneficial feature for those who might stop frequently during their travels and want to ensure the safety of their cargo. However, there are some potential drawbacks to consider. While the soft-shell design allows for easy storage when not in use, it may not be as robust against high-speed winds or rough weather as a hard-shell option. Additionally, although it fits a variety of vehicles, users should ensure that their car's roof can handle the recommended weight capacity safely.

The FIVKLEMNZ Car Rooftop Cargo Carrier offers a generous storage capacity of 21 cubic feet, making it ideal for families or individuals needing extra space for luggage, tents, or sleeping bags. Its dimensions (52 x 40 x 17 inches) allow for ample storage, helping free up inside vehicle space for a more comfortable journey. The carrier is made from 700D Oxford cloth, ensuring durability and 100% waterproof protection, suitable for all weather conditions. The carrier’s genuine waterproof zipper and double flap add to its weatherproof capabilities, making it reliable for various travel scenarios.

For security, it comes with 10 reinforced adjustable straps and an anti-slip mat, keeping the bag firmly in place even on bumpy roads, alongside a security lock for theft prevention. It's versatile and can be installed on vehicles with or without roof racks using the provided door hooks, simplifying the installation process. However, being a soft-shell carrier, it may not offer the same level of protection as hard-shell alternatives. Additionally, the front and back straps require careful handling to avoid tearing, indicating potential durability concerns over long-term use.

Weighing 10.3 pounds, it balances strength and weight, but its aerodynamics might not be as efficient as sleeker, hard-shell models. In summary, this cargo carrier is best suited for those needing extra storage space with easy installation and reliable waterproof protection but might not be ideal for those seeking maximum durability or aerodynamics.

The box is constructed from durable UV-resistant ABS material, ensuring it can withstand harsh weather conditions and long-term use. Weighing just 28 pounds, it's relatively lightweight for its size, which aids in easier installation and handling.

The rear opening design provides convenient access to your belongings while keeping you safe from traffic. The tool-free mounting hardware simplifies installation and removal, fitting well with SportRack systems, square bars, round bars, and most factory racks, though it's always wise to check the fit guide for compatibility. For security, the box includes a key and lock to secure both your contents and the cargo box itself.

One downside is the maximum weight capacity of 100 pounds, which may be limiting for some users. Additionally, aerodynamics could be affected depending on your vehicle's design, potentially impacting fuel efficiency. Despite these minor drawbacks, the SportRack Vista XL is a reliable and practical cargo box with a user-friendly design, suitable for those needing extra storage space on their travels.
