10 Best Car Top Cargo Carriers 2025 in the United States

The Thule Motion 3 XXL rooftop cargo box is a spacious and well-designed carrier ideal for families or anyone needing extra storage space on top of their vehicle. It offers a generous 21 cubic feet capacity and can hold up to 165 pounds, which suits most gear from luggage to sports equipment. Measuring about 96 by 39 by 20 inches, it’s quite large, so make sure your vehicle can accommodate its size. The box is made from durable aluminum, providing a strong and lightweight shell that helps protect your items. Its aerodynamic, wing-shaped design with a forward-leaning nose reduces wind drag, which can help improve fuel efficiency compared to bulkier carriers.

Mounting is straightforward thanks to the PowerClick quick-mount system, which signals when it’s securely attached, making installation faster and tool-free. Opening and closing the lid is easy with one hand, aided by a sturdy lid and wide handle, which adds convenience when loading or unloading. The SlideLock system enhances security by automatically locking the lid and showing when it’s properly closed, giving peace of mind that your belongings are safe. However, the box isn’t water resistant, so it’s best used in dry conditions or with waterproof bags inside. At 35 kilograms (about 77 pounds), it’s relatively heavy for installation, so some users may need assistance mounting it.

The box comes in a neutral titan color and offers optional accessories like interior lighting and protective liners, which are sold separately. This rooftop box represents a strong choice for anyone wanting a large, secure, and aerodynamic cargo carrier, especially if easy mounting and reliable locking are priorities.

The Thule Motion 3 LTitan car-top cargo carrier is a well-rounded option for those seeking additional storage space for their vehicle. It boasts a substantial capacity of 450 liters, making it suitable for long trips or transporting bulky items. The dimensions (80 x 38 x 18 inches) provide ample space while ensuring it fits most vehicle roofs comfortably. With a weight limit that supports significant load, it is versatile for various uses.

Constructed from aluminum, it offers durability and resistance to weather elements, enhancing its lifespan and protecting your belongings from rain and snow. The aerodynamic design, featuring a wing-shaped profile and forward-leaning nose, reduces drag and improves fuel efficiency, which is a notable advantage for long-distance travelers. The PowerClick quick-mount system simplifies the installation process, ensuring a secure fit with an audible click. This user-friendly feature is beneficial for those who may not be experienced with roof-mounted carriers.

The SlideLock system enhances security by providing separate functions for locking and opening, and it indicates when the box is securely closed. This adds an extra layer of protection for your items. However, the carrier's large size and weight (24.04 kilograms) may make it cumbersome to handle and install for some users. Additionally, while the aluminum material is strong, it may not absorb impacts as well as some softer materials, potentially risking damage in the event of a collision. The product includes several optional accessories like an interior box light and protective liner, which are useful but add to the overall cost. It ranks highly in its category (#2 in Vehicle Hard-Shell Carriers), making it essential to consider whether its size and features align with your specific needs and vehicle type.

The MeeFar Car Roof Bag XBEEK Rooftop Cargo Carrier Bag offers ample storage space with its 20 cubic feet capacity, making it suitable for large trips where you need to carry multiple suitcases, tents, or sleeping bags.

Constructed from 700D PVC tarpaulin, the bag is both waterproof and tear-proof, ensuring durability and reliable protection for your belongings in various weather conditions.

The soft shell design allows it to be folded and stored easily when not in use, which is a space-saving feature. It weighs 3.9 kilograms, making it relatively lightweight for its size and capacity. The universal compatibility means it can be used on any car or SUV, whether or not they have a roof rack, adding to its versatility. Installation is straightforward with the included anti-slip mat, 10 reinforced straps, and 6 door hooks, which provide a secure attachment.

Additionally, the included combination lock enhances the security of your belongings by preventing the zippers from slipping. The aerodynamics of the bag might not be as efficient as hard-shell carriers, potentially affecting fuel efficiency.
