10 Best Roof Cargo Boxes 2025 in the United States

The INNO BRM660BK Wedge Cargo Box features a sleek, gloss black design with a moderate 11 cubic feet of storage space, suitable for small to medium loads such as luggage or sports gear. Weighing 42 pounds, it balances sturdiness with manageable weight. Constructed from durable plastic, it offers decent weather resistance to help keep cargo dry in light rain, though it is not fully waterproof. Its aerodynamic wedge shape is designed to reduce wind drag, which may improve fuel efficiency compared to bulkier cargo boxes.

Installation is straightforward thanks to a universal mounting system compatible with most roof racks, including aero, square, and round bars, featuring an adjustable track for easy positioning and hatch clearance. The dual-side opening enhances convenience for loading and unloading. For security, the cargo box includes a safety lock that allows key removal only when the box is fully closed, ensuring peace of mind.

This cargo box is a solid choice for casual users seeking a stylish, easy-to-install roof storage solution with decent capacity and security. It is less suited for heavy-duty or professional use, as the plastic shell, while durable, may not withstand rougher handling as well as some metal alternatives. The product comes with a limited lifetime warranty, providing standard reassurance.

The Thule Force 3 is a robust choice for those in need of a large capacity roof cargo box. With its generous 21 cubic feet of storage, it is ideal for families or individuals requiring substantial space for road trips or outdoor activities. The box is designed to be aerodynamic, which should help minimize wind resistance and noise when driving. Made from durable plastic, the box is built to withstand daily wear and tear, making it suitable for active lifestyles and different weather conditions.

One of its standout features is the dual-sided opening, allowing for easy access from either side of the vehicle, a convenient option when packing or unpacking your cargo. The quick and intuitive mounting system ensures the box is securely attached and provides a clear indication when correctly mounted, making installation straightforward even for those not mechanically inclined.

Security is well-handled with the SlideLock system, which separates the locking and opening functions, ensuring that the lid is securely closed and locked, providing peace of mind during travel. Additionally, the unit's weatherproof design protects contents from the elements. However, at 53.5 pounds, it is on the heavier side, which might require some assistance during installation. Given its features, it’s best suited for SUVs, trucks, and larger vehicles, though its size might be overkill for smaller cars with less roof space.

In conclusion, the Thule Force 3 seems well-designed for those who need a reliable and spacious roof cargo solution, but potential buyers should consider their vehicle's compatibility with its size and weight.

The Thule Motion 3 Rooftop Box is a large, hard-shell cargo carrier with a spacious 14-cubic-foot capacity, making it suitable for families or anyone needing extra storage on road trips. Its wing-shaped design and forward-leaning nose help reduce wind drag, which can improve fuel efficiency compared to bulkier boxes. Made from sturdy aluminum, it promises durability, though it is not water-resistant, so care is needed in heavy rain. Weighing 23.5 kg, it’s relatively easy to handle given its size.

The PowerClick quick-mount system simplifies installation by giving a clear click when properly secured, making it user-friendly and ensuring safety on the road. Security is enhanced by the SlideLock system, which automatically locks the lid and visually confirms when it’s closed, giving peace of mind that belongings are safe. A wide handle makes opening and closing smooth with one hand, adding to convenience. Optional accessories like interior lighting and protective liners add value but come separately.

The box fits universally on most roof racks, though its large size means you should check your vehicle’s roof space before buying. It represents a reliable, aerodynamic cargo box with good security and ease of use, especially suited for longer trips or when carrying bulky gear. Just keep in mind the lack of water resistance if you often face wet weather.
