More Details on Our Top Picks
Thule 614 Pulse Cargo Box, Medium, Black
The Thule 614 Pulse stands out for its generous 14 cubic feet of storage, making it ideal for snowboarders and winter gear. Its quick-mount system simplifies installation, and the passenger-side opening ensures easy access, even when parked on busy streets. Compared to the Thule Force 3 XL, which offers slightly less space but a sleeker look, the Pulse’s rugged build is tailored for snow enthusiasts. However, its weight at 34 lbs can make handling alone challenging, and its design is somewhat specialized, limiting its use for other cargo types. This box is best suited to winter sports lovers who prioritize secure, easy access for bulky gear.
Pros:- Provides ample 14 cubic feet of storage space
- Quick and secure mounting system
- Passenger-side opening for easy access
- Central locking for safety
Cons:- Heavy at 34 lbs, difficult to handle alone
- Designed primarily for snowboards, limiting versatility
Best for: Snowboarders or skiers needing secure, accessible gear storage
Not ideal for: General travelers with everyday luggage, due to its specialized design and weight
- External dimensions:67 x 35 x 16 inches
- Internal dimensions:61 x 33 x 14 inches

- Product weight:34 lbs
- Height off crossbar:16 inches

Its safety indicator for mounting and the SlideLock system provide peace of mind during use, while dual-side access simplifies loading and unloading from either side of the vehicle. Compared to the Thule 614 Pulse, which is more specialized for snow gear, the Force 3 XL emphasizes versatility and daily practicality. Its bulkiness may pose challenges on smaller vehicles, and the limited color options might not appeal to everyone. This cargo box is ideal for those seeking reliable, everyday cargo space with straightforward installation.
Pros:- Durable, sleek design suitable for daily use
- Easy and secure mounting with safety indicators
- Provides convenient dual-side access
- Extensively tested for safety and reliability

MIDABAO 20 Cubic Waterproof Car Roof Top Carrier with Anti Slip Mat
The MIDABAO 20 Cubic Feet Roof Top Carrier delivers an expansive 20 cubic feet of waterproof cargo space, making it ideal for long trips in unpredictable weather. Its PVC construction ensures contents stay dry, and the included anti-slip mat enhances stability during travel. Unlike rigid boxes, this carrier attaches with multiple straps, offering compatibility with almost all vehicle types, including those without roof racks. Compared to the rigid Thule Force 3 XL, this bag provides greater flexibility for storage and storage when not in use, but it can be bulky when stored and requires proper strap tension to prevent shifting. This is best suited for travelers facing variable weather conditions who need large, waterproof capacity.
Pros:- Large 20 cubic feet capacity for extra cargo needs
- Waterproof PVC material keeps contents dry
- Easy to install with multiple straps and anti-slip mat
- Fits all cars with or without roof racks
Cons:- Bulky to store when not in use

Our verdict“This waterproof carrier excels for weather-resistant, flexible cargo when maximum space is needed on long trips.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys
The TUFFIOM 13.4 cu.ft. cargo box offers a balanced capacity with durable ABS construction and dual-side opening, making it suitable for SUV, car, and van owners seeking security and convenience. Its locking system with keys adds a layer of safety, while the streamlined design minimizes drag, benefiting fuel efficiency. It compares favorably to the Thule Pulse 2 M in durability and security but offers slightly less capacity, which may limit larger cargo needs. Installation can be tricky for some, and peeling the protective film is an extra step before use. This is an excellent choice for SUV drivers who prioritize security and quick access from both sides.
Pros:- Dual-side opening for easy access
- Secure locking system with keys
- Durable ABS material for long-lasting use
- Streamlined design reduces drag
Cons:- Requires peeling protective film before use
- Installation may be challenging for some users
Best for: SUV or van owners prioritizing security and dual access
Not ideal for: Travelers needing maximum capacity or those with smaller crossbars
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Max Load Capacity:150 lbs
- Material:ABS
- Weight:approximately 24.25 lbs
Our verdict“This model suits large vehicle owners who need secure, accessible storage without excessive capacity.”
Thule Force 3 L US Cargo Box
The Thule Force 3 L US provides a modest 3 liters of capacity, which makes it ideal for light, daily needs or smaller cargo. Its sleek, aerodynamic profile minimizes wind resistance and noise, making it suitable for city driving. The quick mounting system and SlideLock feature ensure safety and ease of use, although its capacity may be too limited for bulky or multiple items. It compares to the larger Thule 614 Pulse but is more suited for minimal cargo, not heavy-duty or gear-heavy trips. The high price for such a small capacity might deter cost-conscious buyers. This is best for urban drivers or occasional users who need a compact, secure cargo solution.
Pros:- Easy and secure mounting with safety indicator
- Provides convenient dual-side access
- Durable construction with sleek, aerodynamic design
- Long-lasting, tested for road safety
Cons:- Limited capacity (3 L) may not meet larger cargo needs
- Potentially high price for such a small volume
Best for: Urban drivers or those with light, daily cargo needs
Not ideal for: Families or travelers requiring large cargo space
- Capacity:3 L
- Mounting System:Quick and secure with indicator
- Locking System:SlideLock with keys
- Material:Durable construction
- Dimensions:61″ L x 27.6″ W x 13.8″ H
Our verdict“This cargo box is ideal for city dwellers or those with minimal, everyday cargo requirements.”
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Ft
The Thule Pulse 2 M stands out for its balance of capacity, durability, and user-friendly features. Its 14 cubic feet of space is sufficient for most family trips, and the dual-side opening makes access convenient from either side of the vehicle—more flexible than the Thule Pulse 2 L, which offers slightly more capacity but less maneuverability in tight spaces. The tool-free attachment system with a torque indicator ensures secure, straightforward installation, reducing the hassle often associated with roof boxes. Made from weather-resistant ASA-ABS plastic, it promises durability for all seasons, though specific dimensions are not provided, which could be a drawback for fitting in tight garages or roof racks with limited clearance. Compared with larger options like the Thule Motion 3, it offers less internal capacity but excels in ease of use and quick access, making it ideal for frequent travelers who prioritize convenience over maximum volume.
Pros:- Easy to access gear from both sides of the vehicle
- Secure, tool-free installation with torque indicator
- Weather-resistant and durable construction
Cons:- Specific dimensions are not provided, which might affect fitting in tight spaces
- Limited information on the weight of the cargo box itself
Best for: Families needing a reliable, easy-to-install cargo box with balanced capacity and weather resistance.
Not ideal for: Owners of very large vehicles or those requiring maximum storage capacity, as it might feel limited compared to bigger options like the Thule Motion 3.
- Capacity:14 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:Not specified
Our verdict“This cargo box makes the most sense for users seeking a durable, easy-to-use solution with good capacity for regular trips.”
GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Roof Luggage Storage
The GarveeTech Rooftop Cargo Box offers a generous 12 cubic feet of storage, making it a solid choice for budget-conscious travelers needing extra space. Its durable ABS construction ensures waterproof and UV-resistant protection, comparable to the Thule Pulse 2 M, but at a likely lower price point—ideal for those seeking a practical, weatherproof solution. The dual-sided opening enhances convenience, especially on busy or tight-loading situations, and security features like keys and straps add peace of mind. However, verification of roof rack compatibility is necessary, and with only a one-year warranty, durability over multiple seasons might be uncertain. Its slightly smaller capacity than the Thule Motion 3 makes it less suited for large families or extensive gear, but it excels for occasional road trips where weather resistance and affordability are priorities.
Pros:- Durable and weather-resistant construction
- Provides ample extra storage space
- Dual-sided opening for convenience
- Includes security features like keys and straps
Cons:- Requires verification of roof rack compatibility
- Limited warranty period of one year
Best for: Budget-conscious families or solo travelers needing weatherproof, reliable cargo space.
Not ideal for: Those with very large vehicles or frequent long trips requiring maximum storage, as it offers less capacity than larger models.
- Material:ABS
- Capacity:12 cubic feet (340L)
- Dimensions:54.3″L x 31.5″W x 13.4″H / 62.2″L x 31.5″W x 13.4″H
- Max Capacity:165 lbs
- Compatibility:All vehicles with roof rack
Our verdict“This pick is perfect for budget-minded users who want weatherproof storage with decent capacity and ease of access.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 impresses with its sleek, aerodynamic design, which significantly reduces drag and improves fuel economy compared to boxier models like the GarveeTech. Its forward-leaning nose and wing-shaped profile streamline airflow, making it a smart choice for road warriors concerned with efficiency. The quick-mount PowerClick system and Torque Indicator simplify installation, and the secure SlideLock mechanism ensures the contents stay safe. Compatibility with accessories such as interior lighting and protective liners enhances convenience, though the internal capacity details are limited, and the premium features come with a higher price tag. The durable construction and advanced design make it ideal for frequent travelers willing to invest in performance and longevity, but less so for budget shoppers who prioritize capacity over aerodynamics.
Pros:- Aerodynamic design reduces drag and improves fuel efficiency
- Easy to mount with quick, secure PowerClick system
- Secure locking with visual indicators
- Compatible with various accessories
Cons:- Limited information on internal capacity
- No details on material durability
- Potentially high cost for advanced features
Best for: Frequent travelers and car owners seeking a premium, aerodynamic cargo box with advanced features.
Not ideal for: Casual users or those on a tight budget, since its high cost may not justify the benefits for occasional trips.
- 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“This model suits those seeking a high-performance, aerodynamic roof box with premium features and durability, at a higher price point.”
Car Rooftop Cargo Carrier Bag, 21 Cubic Feet, Waterproof, Heavy Duty 840D Car Roof Bag for All Vehicles with/Without Racks
The Car Rooftop Cargo Carrier Bag offers an expansive 21 cubic feet of storage, making it ideal for big families or gear-heavy trips. Its heavy-duty 840D waterproof fabric with reinforced seams guarantees protection against rain, snow, and rough weather—more flexible than hard-shell boxes like the Thule Pulse 2 M. The adjustable straps, door hooks, and luggage lock facilitate secure, customized installation, though the stiff fabric might be challenging for some users to handle during setup. While it excels in capacity and weatherproofing, its soft-sided design may not provide the same protection against impacts or theft as rigid options, and careful installation is necessary to prevent shifting during transit. This carrier is best for travelers prioritizing maximum volume and weather resistance over rigid protection or sleek aesthetics.
Pros:- Durable, waterproof 840D fabric with reinforced seams
- Large capacity suitable for multiple luggage pieces and gear
- Easy to install with adjustable straps and accessories
- Includes anti-slip mat, door hooks, and luggage lock
Cons:- May require careful setup to prevent shifting
- Heavy-duty fabric can be stiff and difficult to handle
Best for: Large families or adventurers needing maximum capacity and weatherproofing for extended trips.
Not ideal for: Urban drivers or those requiring a sleek, impact-resistant solution, as the soft-sided bag offers less protection against theft and rough handling.
- Material:840D abrasion-resistant PVC fabric
- Capacity:21 Cubic Feet
- Waterproof:Yes
- Includes:Anti-slip mat, 6 door hooks, 2 extra straps, luggage lock
Our verdict“This cargo carrier is best suited for users demanding maximum volume with strong weatherproofing capabilities for long, gear-heavy trips.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft
The Thule Pulse 2 L offers a slightly larger 16 cubic feet of storage compared to the Pulse 2 M, with the same weather-resistant durability. Its capacity makes it more suitable for larger families or those with more gear, but it shares the same dual-side opening that enhances accessibility, a feature that GarveeTech lacks. While it provides an easy, tool-free installation with a torque indicator, its weight might be a concern for some users handling rooftop gear. The absence of detailed internal dimensions means it could be less ideal for bulky or oddly shaped items. This model caters well to users who want a bit more volume without sacrificing ease of use or weather protection, but it’s less suited for those who need maximum space or a lightweight option.
Pros:- Large 16 cubic feet capacity
- Easy, tool-free installation with torque indicator
- Weather-resistant and durable construction
- Accessible from both sides of the vehicle
Cons:- No specific internal dimensions provided
- Potentially heavy for some users
- Limited detailed material durability info
Best for: Families or travelers requiring additional storage capacity with easy access and weatherproof features.
Not ideal for: Owners of very small or compact vehicles where even 16 cubic feet might feel bulky or hard to fit in tight garage spaces.
- Capacity:16 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:Not specified
Our verdict“This cargo box is ideal for those wanting more volume and dual-side access without a significant increase in handling complexity.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This cargo box stands out for its rugged ABS plastic shell, offering robust weather resistance that surpasses many soft-sided options. Unlike the SportRack Vista XL, which emphasizes large capacity with UV resistance, this model focuses on protecting belongings against harsh elements, making it ideal for unpredictable outdoor conditions. The secure lock and straightforward crossbar mounting ensure peace of mind and quick setup, but it’s limited to vehicles with compatible cross bars. Its 11-cubic-foot capacity isn’t as large as some rivals, meaning it’s better suited for moderate gear loads rather than extensive trips. The design does involve some extra tools for installation, which could be a hassle for quick swaps. Overall, this pick is perfect for travelers prioritizing durability and weatherproofing over sheer volume, though it’s less flexible for vehicles without cross bars.
Pros:- Durable, weather-resistant ABS plastic shell
- Secure lock system for valuables
- Easy to install on cross bars
Cons:- Limited compatibility to vehicles with cross bars
- Relatively small capacity compared to larger boxes
Best for: Travelers needing a weatherproof, secure cargo solution for vehicles with cross bars.
Not ideal for: Owners of vehicles without cross bars or those seeking maximum storage volume for family trips.
- Material:ABS plastic
- Capacity:11 cubic feet
- Dimensions:53 x 34 x 15 inches
- Weight Capacity:110 lbs
- Color:Black
- Mounting:Universal cross bar fit
Our verdict“This cargo box is best for users prioritizing weatherproof durability over maximum volume and ease of mounting on a variety of vehicles.”
SportRack Vista XL Rear Opening Cargo Box
Compared with the smaller, more weather-focused options like the Auto Dynasty box, the SportRack Vista XL offers an impressive 18 cubic feet of storage, making it a strong choice for families or groups with lots of gear. Its rear-opening design simplifies access, especially when parked, though it might be less convenient during travel if side access is preferred. The UV-resistant ABS shell ensures durability against sun exposure, and the tool-free mounting makes setup straightforward. However, the rear opening can be limiting for quick loading and unloading on the go, and its maximum weight capacity of 100 pounds could restrict heavy gear. This model is ideal for those who prioritize large volume and less frequent access, but it may be less suitable for frequent, quick stops or for users seeking side access.
Pros:- Huge 18 cubic foot capacity
- UV-resistant ABS construction
- Tool-free, easy installation
- Secure lock for contents
Cons:- Rear opening may be less convenient for frequent access
- Limited weight capacity for heavy loads
Best for: Families or outdoor enthusiasts needing maximum storage space with easy installation.
Not ideal for: Users who require quick access during travel or have limited roof rack spacing, due to rear opening design.
- Capacity:18 cubic feet
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Min-Max Crossbars Spacing:23 5/8 – 29 3/4 inches
- Max Weight Capacity:100 pounds
- Warranty:25 years
Our verdict“This cargo box is best suited for users who need maximum volume and don’t mind rear access for loading and unloading.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier Travel Luggage Box
This model offers a balanced mix of capacity and ease of use, with 11 cubic feet of storage and a wide, 14-inch opening that simplifies loading large or bulky gear. Compared to the SportRack Vista XL, which emphasizes maximum volume, the Auto Dynasty provides a more manageable size for quick access and installation, though it still supports a solid 110 lbs weight limit. Its weather-resistant ABS shell ensures belongings are protected against rain and impacts, making it suitable for outdoor adventures. However, it requires careful crossbar dimension checks and may involve tools for mounting, adding some effort to setup. It’s perfect for users who want reliable, secure outdoor storage without the bulk of larger boxes, but it’s less ideal for those with non-standard roof rack sizes or seeking maximum volume.
Pros:- Spacious 11 cubic feet capacity
- Wide 14-inch opening for easy loading
- Weather-resistant and impact-protected
- Secure lock system
Cons:- Installation may require tools and checking crossbar compatibility
- Limited to vehicles with compatible cross bars
Best for: Outdoor lovers and families needing secure, weatherproof storage with straightforward loading.
Not ideal for: Owners with incompatible crossbar sizes or those desiring maximum cargo volume for extended trips.
- Dimensions:53″ L x 34″ W x 15″ H
- Capacity:11 Cubic Feet
- Weight Limit:110 lbs
- Material:UV-protected, weather-resistant ABS
- Mounting Compatibility:Max 13 inches wide cross bar
Our verdict“This cargo box is ideal for outdoor enthusiasts seeking a weatherproof, easy-to-load option for secure travel, especially on vehicles with standard cross bars.”
How We Picked
I evaluated these roof cargo boxes based on several critical criteria that matter to buyers: overall performance, build quality, ease of installation and use, weather resistance, and value for money. I prioritized models that strike a good balance between capacity and aerodynamics, ensuring they don’t negatively impact fuel efficiency. Durability and security features like lock systems were also key factors, as well as versatility across different vehicle types. Products are ranked to highlight those that excel in these areas while considering real-world usability and tradeoffs like price and size limitations.Factors to Consider When Choosing Roof Cargo Box
Choosing the right roof cargo box involves more than just capacity. It’s important to consider compatibility with your vehicle, weather resistance, ease of access, and security features. Understanding these factors helps avoid common pitfalls like overpaying for unnecessary features or selecting a box that’s too small or large for your needs. Carefully weighing these considerations ensures you get a model that enhances your trips without adding hassle or compromise.Size and Capacity
Size and capacity are the most obvious considerations, but matching them to your actual needs is vital. Oversized boxes may cause handling issues and reduce fuel efficiency, while too small models limit what you can carry. Think about the volume you typically need—for family gear or outdoor equipment—and choose a box that comfortably accommodates that. Keep in mind vehicle roof load limits to avoid overloading and potential safety issues.
Weather Resistance and Durability
Rain, snow, and sun can all take a toll on a roof cargo box. Look for models with high-quality, waterproof shells and secure seals to keep contents dry. Material choice impacts longevity; ABS and polycarbonate shells tend to resist cracking and UV damage better than cheaper plastics. Investing in a weather-resistant model means your gear stays protected, reducing the risk of damage and the need for replacement over time.
Ease of Installation and Access
Ease of mounting and removing the box can save time during busy trips. Dual-side opening options make loading and unloading more convenient, especially on tight parking spots or narrow roofs. Check if the mounting system is compatible with your vehicle’s roof rails or crossbars and whether it’s straightforward to secure. A well-designed lock system adds security without complicating daily use, balancing convenience with peace of mind.
Security Features
Protecting your belongings from theft is a key consideration. Look for integrated locks or key-based security systems that deter unauthorized access. Some models offer reinforced shells or hidden lock points, which can add extra protection. Remember, more secure models often come with increased weight and cost, so balance your security needs against practical factors like ease of handling and budget.
Price and Value
Prices vary widely, reflecting differences in capacity, durability, and features. While it’s tempting to choose the cheapest option, investing in a higher-quality model often pays off through better weather resistance, security, and longevity. Conversely, for occasional use or short trips, more affordable models can suffice, especially if they meet your size and security needs. Always weigh the features against your budget to find the best value.
Frequently Asked Questions
Will a roof cargo box affect my vehicle’s fuel efficiency?
Yes, adding a roof cargo box increases aerodynamic drag, which can reduce your vehicle’s fuel efficiency. The extent depends on the size and shape of the box, as well as your driving speed. To minimize impact, opt for a sleek, low-profile model and avoid exceeding recommended weight limits. Removing the cargo box when not in use can also help maintain better fuel economy during everyday driving.
Can I install a roof cargo box on any vehicle?
Most roof cargo boxes are designed to fit a wide range of vehicles with compatible roof rails or crossbars. However, some models require specific mounting systems or have weight limits that may not suit all vehicles. Before purchasing, check your vehicle’s roof load capacity and ensure your existing roof rack system is compatible. Proper installation is crucial for safety and stability, so follow manufacturer instructions carefully.
Are hard-shell roof boxes better than fabric bags?
Hard-shell roof boxes generally offer superior weather resistance, security, and durability compared to fabric bags. They protect contents from rain, snow, and impact, making them ideal for longer trips or unpredictable weather. Fabric bags are lighter and often more affordable but tend to be less secure and less waterproof. Your choice depends on how much protection you need versus weight and budget considerations.
How do I prevent my roof cargo box from damaging my vehicle’s paint?
To protect your vehicle’s paint, always use padding or mounting pads between the roof rack and the cargo box. Regularly check that the mounting system is secure to prevent movement that could scratch or dent the roof. Avoid over-tightening straps or clamps, which can cause pressure points. Proper installation and regular maintenance help keep your vehicle’s finish in good condition.
What is the typical lifespan of a roof cargo box?
The lifespan of a roof cargo box depends on material quality, exposure to weather, and usage frequency. High-quality models made from durable plastics like ABS or polycarbonate can last 5-10 years with proper care. Regular cleaning, avoiding prolonged exposure to harsh sunlight, and storing the box indoors when not in use can extend its life. Cheaper or poorly maintained models may need replacement sooner.
Conclusion
For most buyers, the Thule Pulse 2 M offers an excellent balance of capacity, security, and ease of use, making it ideal as the best overall choice. Those seeking the largest storage capacity at a reasonable price might prefer the Thule Force 3 XL. If you’re new to roof cargo boxes or only need occasional extra space, a more affordable and straightforward model like the Car Rooftop Cargo Carrier Bag could be enough. For premium buyers prioritizing durability and advanced features, the Thule Motion 3 stands out as a top-tier option. Ultimately, your specific vehicle, budget, and travel needs will determine the best fit.
