More Details on Our Top Picks
JEGS Rooftop Cargo Carrier – 18 Cubic Ft Weatherproof Roof Rack Storage
The JEGS Rooftop Cargo Carrier stands out for its spacious 18 cubic feet capacity, making it ideal for large families or those needing to carry bulky gear. Its weatherproof design and secure four-corner locks ensure valuables stay dry and safe, while the aerodynamic shape helps improve fuel efficiency compared to bulkier options like the Auto Dynasty Heavy Duty. However, its weight of 110 lbs could pose challenges for installation, especially on lighter vehicles, and its rear-only access limits convenience when loading bulky items from the side. This model is best suited for drivers prioritizing maximum storage with weather protection but willing to handle a heavier, rear-access-only box.
Pros:- Large 18 cubic ft capacity for extensive storage needs
- Weatherproof construction with secure locking
- Aerodynamic design enhances fuel efficiency
- Easy rear access for loading and unloading
Cons:- Heavy at 110 lbs, challenging for some users
- Limited to rear opening access, less convenient for bulky side loading
Best for: Large families or outdoor enthusiasts who need maximum cargo space with weatherproof security.
Not ideal for: Car owners with lightweight or small vehicles that struggle with heavier cargo carriers or require side access.
- Capacity:18 Cubic Feet
- Material:HDPE plastic
- Dimensions:57 L x 39 W x 19.5 H inches
- Weight Capacity:110 Lb
- Design:Aero

Our verdict“This carrier is perfect for those needing maximum space and weather protection, despite its weight and limited access points.”
Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier, Strut Assisted, Lockable & Weatherproof
The Rough Country Cargo Box offers a solid 14.5 cubic feet of weatherproof storage with a user-friendly, strut-assisted lid, making it easier to load than some competitors like the Perflex Exclusive. Its UV-protected ABS material ensures durability against the elements, and its universal fit means installation is straightforward on most crossbars without drilling, providing good value for the price. However, its 125 lbs maximum load and potential fit limitations on certain roof racks could restrict heavy or bulky cargo. If you seek reliable, lockable weatherproof storage without high cost, this box provides a balanced mix of features with some compromises on weight capacity and compatibility.
Pros:- Expands storage with weatherproof, lockable design
- Strut-assisted lid for easier loading
- Easy to install on most crossbars without drilling
- UV-protected ABS ensures durability
Cons:- Limited to 125 lbs load capacity

- Interior Dimensions:65″ L x 32″ W x 13″ H
- Max Load:125 lbs
- Installation:Universal crossbar fit, no drilling

Our verdict“This model offers reliable weatherproof storage at a strong value point, suitable for regular outdoor trips but limited by its weight capacity and fit constraints.”
Perflex Exclusive Rooftop Cargo Box Carrier 17.7 Cubic Feet, White
The Perflex Exclusive Cargo Box offers a generous 17.7 cubic feet of space tailored for skis, snowboards, and luggage, with dual-side opening that simplifies access from either side—an advantage over models like the JEGS Carrier. Its aerodynamic shape and impact-resistant ABS make it suitable for winter sports gear, while the tool-free installation ensures quick setup. The main tradeoff is its assembly location, as it’s made in Turkey and assembled in the U.S., which might affect availability. This box excels for snow sports enthusiasts who need easy access and secure, water-resistant storage, but it requires a compatible roof rack and doesn’t include racks itself.
Pros:- Large 17.7 cu ft capacity for bulky gear
- Dual side opening for easy access
- Water-resistant and impact-resistant
- Easy to install without tools
Cons:- Roof racks are not included, requiring additional purchase
- Availability may be affected by manufacturing location
Best for: Winter sports enthusiasts needing quick, side-access for skis and snowboards.
Not ideal for: Car owners without suitable roof racks or those who prefer single-side access for cargo.
- Capacity:17.7 cubic feet
- Material:UV-resistant, impact-resistant ABS
- Dimensions:Approximately 56″ L x 36″ W x 16.25″ H
- Weight Capacity:130 lbs
- Installation:Tool-free, universal fit
- Made in:Turkey, assembled in the U.S.
Our verdict“Ideal for winter sports lovers prioritizing side access and spacious storage, provided they have compatible roof racks and can source this model.”
Auto Dynasty Heavy Duty Hard Shell Roof Top Mount Car Storage Luggage Box
The Auto Dynasty Heavy Duty Cargo Box provides 11 cubic feet of secure, weather-resistant storage with a sturdy ABS shell, making it a good choice for rugged outdoor trips compared to smaller boxes like the DNA MOTORING. Its 110 lbs capacity and durable construction make it suitable for carrying heavier luggage and outdoor gear. The tool-free mounting brackets simplify installation, though it’s limited to vehicles with cross bars no wider than 13 inches, which could exclude some SUVs or crossbar setups. This box caters to those needing a tough, reliable cargo solution for demanding environments, but the smaller capacity and specific fit requirements limit versatility.
Pros:- Sturdy, impact-resistant ABS construction
- Secure lock system for valuables
- Weather-resistant for all-season protection
- Easy tool-free installation
Cons:- Limited to cross bars no wider than 13 inches
- Smaller capacity at 11 cu ft may restrict bulky items
Best for: Outdoor enthusiasts and travelers needing a durable, secure box for heavier gear on standard crossbars.
Not ideal for: Owners with wider roof racks or lighter vehicles that don’t support the 13-inch crossbar limit.
- Dimensions:53 x 34 x 15 inches
- Capacity:11 Cubic Feet
- Weight Limit:110 lbs
- Material:UV-protected, weather-resistant ABS
- Installation:Tool-free mounting brackets
- Fitment:Max 13-inch wide cross bars
Our verdict“This heavy-duty box is a reliable choice for tough outdoor use but is less suitable for larger capacity needs or wider racks.”
DNA MOTORING Rooftop Cargo Box, 13 Cu Ft, Weatherproof, Lockable, Heavy Duty Car Top Storage Case
The DNA MOTORING Cargo Box offers a balanced 13 cubic feet of storage in a compact size, making it suitable for smaller vehicles or those with tight space constraints. Its impact-resistant ABS shell and weatherproof features provide reliable protection, while the double side opening makes loading easier. Compared with larger options like the Perflex Exclusive, this box is less bulky and easier to handle for daily use or shorter trips. However, it requires vehicles with cross bars and does not include mounting hardware, which could add to setup time. It appeals most to drivers with limited roof space or needing a straightforward, weatherproof cargo solution.
Pros:- Decent 13 cu ft capacity for compact spaces
- Weatherproof, impact-resistant construction
- Double side opening for easy access
- Easy to install without tools
Cons:- Requires compatible cross bars, no hardware included
- Limited to 110 lbs maximum load
Best for: Owners of smaller vehicles or SUVs with cross bars who need a manageable, weatherproof storage option.
Not ideal for: People with wider or non-standard roof racks or those requiring higher load capacities.
- Capacity:13 Cubic Feet
- Material:Impact-resistant ABS
- Dimensions:56.3″ L x 36.8″ W x 16.25″ H
- Max Capacity:110 lbs

Our verdict“A practical choice for small vehicle owners seeking weatherproof, manageable cargo space with straightforward installation.”
Thule Force 3 L Sport US
The Thule Force 3 L Sport US excels for those who prioritize durability and quick, effortless access, thanks to its dual-side opening and secure mounting system. Compared to larger options like the Garvee 13.5Cubic, it offers a more compact size, but that also means less capacity for bigger loads. Its sleek, durable shell maintains a professional look, but the limited capacity may frustrate users needing to carry bulkier gear. The slideLock system provides added security, and the quick mount makes installation straightforward, making it ideal for active users who need reliable, frequent access without sacrificing durability. However, it may not be the best choice for those who require weatherproofing or larger volume, as these features aren’t explicitly highlighted.
Pros:- Durable and maintains a sleek appearance
- Easy to access cargo from both sides
- Secure and intuitive mounting system
Cons:- Limited capacity for larger loads
- No specific weather resistance features
Best for: Active families or outdoor enthusiasts needing durable, easy-to-access storage for gear and equipment
Not ideal for: Long road trips requiring large capacity or extreme weather protection, due to limited weather resistance information
- Capacity:3 liters
- Mounting System:Quick, secure, and intuitive
- Locking System:SlideLock with separate locking and opening functions
- Safety Features:Automatically locks and indicates when securely closed
- Item Dimensions:Unknown, compact design
- Material Type:Durable plastic shell
Our verdict“This cargo box suits active users who prioritize durability, security, and quick access over volume or weatherproofing.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 Rooftop Box stands out for its sleek, aerodynamic profile that helps reduce drag and improve fuel economy, making it a smart choice for frequent travelers. Its one-handed lid operation and secure SlideLock system simplify access and security, while the PowerClick torque indicator ensures quick, proper mounting. Unlike the Garvee box, which emphasizes capacity, Thule’s design leans toward efficiency and ease of use, although specific volume details are sparse, making it less ideal for those needing maximum cargo space. Compatibility with accessories like interior lighting enhances usability, but the lack of explicit capacity details means that heavy or bulky loads might be challenging to fit.
Pros:- Aerodynamic reduces drag and improves fuel efficiency
- Easy one-handed opening and secure locking
- Quick mounting with torque indicator
Cons:- No specific capacity size provided
- Additional accessories may be extra cost
Best for: Travelers seeking a sleek, fuel-efficient cargo solution with easy access and mounting
Not ideal for: Heavy loads or large capacity needs, due to limited capacity details and potential accessory extra costs
- Design:Wing-shaped profile with forward-leaning nose
- Mounting System:PowerClick quick-mount with torque indicator
- Locking System:SlideLock with separate lock and open functions
- Accessories:Interior box light, protective liner, storage cover
Our verdict“Ideal for frequent travelers prioritizing efficiency and ease of use over maximum cargo volume.”
Garvee Rooftop Cargo Box Carrier
The Garvee Rooftop Cargo Box Carrier offers a rugged and weatherproof solution, constructed from high-quality ABS, making it ideal for all-weather road trips. Its large size—67.7 inches long with 13.5 cubic feet of space—compared with smaller options like the Thule Force, makes it suitable for those with significant packing needs. The dual-side opening enhances accessibility from either side of the vehicle, and the waterproof, UV-resistant shell provides reliable protection. However, its size demands a compatible roof rack, and its heavy weight might challenge some vehicles, especially without proper mounting hardware. Its substantial capacity makes it a good choice for long journeys but less suitable for smaller vehicles with limited roof space.
Pros:- Rugged, durable ABS construction
- Weatherproof and UV-resistant
- Large capacity with dual-side access
Cons:- Requires compatible roof racks
- Heavy weight may complicate installation
Best for: Long-distance travelers and outdoor adventurers needing maximum capacity and weather protection
Not ideal for: Vehicles with limited roof rack space or those seeking a lightweight, compact carrier
- Item Dimensions:67.7″ L x 31.5″ W x 13.8″ H
- Volume:13.5 cubic feet
- Max Load Capacity:135 pounds
- Material Type:ABS
Our verdict“Best suited for users who need high capacity and weather resistance for extended trips with suitable vehicle racks.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box
The TUFFIOM 13.4 cu.ft. Rooftop Cargo Box offers a balanced mix of capacity, weather resistance, and security, with a spacious 13.4 cubic feet volume and dual-side opening for easy access. Its impact-resistant ABS shell ensures protection from the elements, similar to the Garvee box, but with the advantage of locks with keys for added security. Its dimensions of 61″ x 27.6″ x 13.8″ make it slightly narrower than the Garvee, providing a better fit for narrower roof racks, but it still needs crossbars for installation. The peel-off protective film on the lid can cause initial setup confusion, and its weight of approximately 24 pounds means some effort is needed during mounting. Nonetheless, it is a versatile choice for those needing weatherproof, secure storage.
Pros:- Large capacity with dual-side opening
- Weather-resistant impact ABS shell
- Lockable with keys for security
Cons:- Requires crossbars for installation
- Peeling film on lid may cause confusion
Best for: Families or travelers needing weatherproof, secure cargo with easy dual-side access
Not ideal for: Vehicles without compatible crossbars or users seeking the largest capacity available
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Max Load Capacity:150 lbs
- Material:ABS
- Locking System:Yes, with keys
Our verdict“A solid choice for secure, weatherproof storage with easy access, suitable for families and frequent travelers.”
DNA Motoring Rooftop Cargo Box Carrier
The DNA Motoring Rooftop Cargo Box Carrier provides a generous 11 cubic feet of space at an accessible price point, making it appealing for budget-conscious buyers. Its impact-resistant ABS construction ensures durability, and the lockable lid adds security for valuables. Its dimensions of 53″ x 34″ x 15″ make it comparable in size to the Thule Motion 3, but it requires crossbars for installation, limiting its use to vehicles equipped with compatible racks. Unlike premium options, it lacks advanced features like dual-side opening or integrated accessories, but it covers the basics well for casual users. The absence of tool-free assembly and potential difficulty fitting on narrower roofs are notable tradeoffs.
Pros:- Large 11 cubic feet capacity
- Impact-resistant durable ABS
- Lockable lid for security
Cons:- Requires crossbars for installation
- No tool-free assembly
Best for: Budget-conscious families or casual users needing reliable, secure storage on vehicles with crossbars

- Capacity:11 cubic feet
- Dimensions:53″ L x 34″ W x 15″ H
- Max Weight:110 lbs

- Finish:Glossy Black
Our verdict“Best for budget-minded users who need a reliable, secure cargo box with moderate capacity on compatible vehicles.”
DNA Motoring Universal Heavy Duty Roof Storage Box 12.7 cu. ft. / 360L
This model stands out for its substantial 12.7 cubic feet capacity, making it ideal for carrying bulky gear or multiple luggage pieces without sacrificing security. Unlike the smaller DNA Motoring Rooftop Cargo Box, which offers less space, this heavy-duty version is built with impact-resistant ABS, providing extra durability for frequent use. The lockable lid adds security, but the side-opening design can become cumbersome when fully loaded, requiring extra effort to open and close. Installation is straightforward thanks to its universal fit, yet it depends on your vehicle having cross bars, similar to other options like the Auto Dynasty box. Compared to premium models like the Thule Motion 3, this box offers better capacity for the price but trades off some aerodynamic efficiency and noise reduction. Overall, this pick makes sense for those prioritizing capacity and durability over sleekness and advanced features.
Pros:- Large 12.7 cu. ft. capacity for bulky or multiple items
- Impact-resistant ABS construction offers durability
- Locking system with keys enhances security
- Easy to install without tools
Cons:- Requires existing cross bars for attachment, limiting compatibility
- Side opening can be difficult to operate when fully loaded
- Limited aerodynamic features may increase wind noise
Best for: Buyers needing to carry large, bulky items on a budget who have vehicles equipped with cross bars.
Not ideal for: Drivers seeking a sleek, aerodynamic, or low-profile cargo solution, or those without compatible cross bars.
- Capacity:12.7 cu. ft. / 360L
- Maximum Load:110 lbs
- Dimensions:55″ x 34.5″ x 14″
- Opening:Side opening, stays open until closed
- Material:Impact-resistant ABS
- Color:Black textured finish
- Fitment:Universal, attaches to vehicles with cross bars
Our verdict“This heavy-duty cargo box is best suited for users prioritizing capacity and durability over sleek design or advanced aerodynamics.”

Factors to Consider When Choosing Narrow Rooftop Cargo Boxes
Choosing the right narrow rooftop cargo box involves more than just capacity. Consider your vehicle’s roof rail width, the typical load weight, and how often you’ll need to install or remove the box. Weatherproofing and security features can protect your gear from the elements and theft. Additionally, think about the opening style—dual-side opening can make loading easier, especially on taller vehicles. The material quality impacts durability but may also influence weight and ease of handling. By understanding these factors, you can find a cargo box that fits your vehicle and meets your travel needs without unnecessary compromises.Size and Fit
Measuring your vehicle’s roof width is crucial before choosing a narrow cargo box. Many models are designed to fit roof rails under 28 inches, but some may be wider or have adjustable mounting systems. A box that’s too wide can interfere with side mirrors or cause wind noise, while a too-narrow model might limit capacity. Pay attention to the internal and external dimensions to ensure you get enough space without overextending your roof’s capacity or compromising handling.
Capacity and Load Limits
While a narrow design prioritizes fit, you still need sufficient volume for your gear. Most models here range from about 11 to 17 cubic feet, enough for a few suitcases or camping gear. Keep in mind that higher capacity often means increased weight, which can affect fuel efficiency and handling. Always check the maximum load capacity and ensure your vehicle’s roof can support it safely. Overloading can lead to damage or unsafe driving conditions.
Weatherproofing and Security
Protection from the elements is non-negotiable for outdoor gear, making weatherproofing essential. Look for sealed edges and high-quality materials like ABS or fiberglass that resist UV rays and cracking. Lockable latches add security, especially if you leave your vehicle unattended. Consider dual-side opening if you frequently access the box from both sides for convenience and to reduce the risk of accidental openings while driving.
Ease of Installation and Use
Many narrow cargo boxes feature quick-release or tool-free mounting systems, making installation faster and less cumbersome. A lightweight design helps with handling during mounting, especially if you often swap between vehicles. Check for clear instructions and sturdy mounting hardware—poor installation can lead to instability or damage. Dual-side opening models are generally more user-friendly but may add to the cost and complexity.
Material and Durability
Durability depends on the material—ABS plastic, fiberglass, or heavy-duty polycarbonate are common choices. Thicker shells generally withstand impacts better but add weight. UV resistance prolongs the lifespan, especially if exposed to sunlight regularly. Consider the weight of the cargo box itself, as a heavy model might be more difficult to handle during installation or removal, especially on higher vehicles.
Frequently Asked Questions
Will a narrow rooftop cargo box fit on my SUV with side rails?
Most narrow rooftop cargo boxes are designed to fit standard roof rails, but it’s essential to check the specific width of your rails and compare it with the maximum width of the cargo box. Many models specify compatibility with certain rail types or include adjustable mounting systems that can accommodate a range of rail widths. Measuring your roof rails accurately before purchasing ensures a secure fit and optimal performance.
Can I carry bulky or heavy gear in a narrow cargo box?
Yes, but the capacity depends on the specific model. Many narrow boxes are designed with a balance of width and volume, so they can handle bulky gear like camping equipment or sports gear. Always verify the maximum load capacity to prevent overloading, which can compromise safety and damage your vehicle or the cargo box. Distributing weight evenly and securing your load properly is key to safe transport.
Are narrow rooftop boxes suitable for winter or snowy conditions?
Weather-resistant models with sealed shells and UV protection are suitable for winter use, protecting your gear from snow and moisture. However, always check if the box’s locking mechanisms remain operable in cold temperatures and if the material resists cracking or becoming brittle. Regularly inspect and clean the box after winter trips to maintain its integrity and longevity.
How important is the material of the cargo box?
The material influences durability, weight, and weather resistance. ABS plastic is lightweight and impact-resistant, while fiberglass offers superior durability and UV resistance but can be heavier and more expensive. Polycarbonate shells strike a balance between strength and weight. The right choice depends on your travel frequency, load size, and budget, but investing in a sturdy material generally extends the lifespan of your cargo box.
What features make a rooftop cargo box easier to use daily?
Features such as dual-side opening, lightweight construction, and tool-free mounting significantly enhance ease of use. Dual-side opening allows access from either side, reducing the need to park in specific spots. Lightweight models are easier to lift and position, especially if you frequently install or remove the box. Clear, simple locking mechanisms also streamline daily use, making your trips more convenient and less stressful.
Conclusion
For the casual driver or occasional traveler, the DNA MOTORING Rooftop Cargo Box offers a budget-friendly, reliable option. Those seeking the best overall experience should consider the Thule Motion 3 for its premium build and sleek design. If size and capacity are your priorities, the Garevee Rooftop Cargo Box provides impressive weight limits and security features. Beginners or infrequent users will benefit from models with easy, tool-free installation, while heavy-duty or frequent travelers should look at more durable, weatherproof options. Matching your vehicle’s roof width and your specific needs will ensure you get the best fit and performance.
