More Details on Our Top Picks
Thule Motion 3 Rooftop Cargo Box
The Thule Motion 3 stands out for its sleek, aerodynamic shape that reduces drag, which can lead to better fuel economy compared to bulkier options like the FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier. Its quick-mount system and torque indicator make installation smoother, though some users report that fitting it securely can still be tricky. Compared to the GarveeTech box, it offers more refined aesthetics and better integration with modern vehicles but lacks detailed accessory compatibility info. This model makes the most sense for drivers seeking a balance between style, ease of use, and capacity, especially if fuel efficiency is a priority. The limited details on certain features and installation concerns mean it might not be ideal for those new to roof boxes or with complex roof rack setups.Pros:- Aerodynamic shape reduces drag and improves fuel efficiency
- Quick-mount system simplifies installation
- Spacious interior for large luggage and gear
- Automatic lock indicator enhances security
Cons:- No detailed info on accessory compatibility
- Some users find installation less straightforward than expected
Best for: Owners of modern vehicles looking for a stylish, aerodynamic cargo solution that minimizes drag and improves fuel economy
Not ideal for: Budget-conscious buyers or those seeking a highly customizable or affordable option, due to limited accessory info and installation complexity
- Brand:Thule
- Model Number:197074566126
- Item Dimensions:81″L x 38″W x 18″H
- Included Components:Rooftop cargo carrier
- Warranty:Limited Lifetime
Our verdict“This cargo box is ideal for those prioritizing sleek design and efficiency, willing to manage a potentially complex setup.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ soft roof bag offers a generous 21 cubic feet of waterproof storage, making it a solid choice over rigid boxes like the Thule Pulse 2 M for those needing flexibility and extra space. Its durable 840D PVC and welded seams ensure excellent weather resistance, though it can be bulky to store when not in use. Compared with the more rigid GarveeTech box, this bag is easier to fold or stow away, but it may be less secure during high-speed travel if not properly secured. It’s ideal for outdoor enthusiasts who need maximum capacity and weatherproofing without sacrificing versatility. However, its weight and bulk could be challenging for users with limited storage space or those unfamiliar with securing soft luggage on roofs.Pros:- Highly waterproof with welded seams and durable PVC
- Large capacity fits multiple suitcases and gear
- Universal fit for all vehicle types, easy to install
- Complete travel kit included
Cons:- Bulky and difficult to store when not in use
- Heavy-duty material can be stiff and less flexible
Best for: Road trippers and outdoor adventurers seeking ample, waterproof storage that’s easy to store when not in use
Not ideal for: Drivers who prioritize rigid security and ease of installation over maximum capacity, or for those with small vehicles that can’t handle bulky gear
- Capacity:21 cubic feet
- Dimensions:52 x 40 x 18 inches
- Material:840D PVC
- Seams:High-frequency welded
- Includes:Anti-slip mat, luggage lock, reinforced straps, door hooks, storage bag
Our verdict“This soft roof bag is best for those needing maximum waterproof capacity and flexibility, despite its bulkiness when stored.”
GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof Hard Shell, Black
The GarveeTech cargo box offers a sturdy 12 cubic feet of weather-resistant storage, making it a practical alternative to larger soft bags like the FIVKLEMNZ. Its ABS hard shell provides reliable protection from the elements and impacts, although the limited 30-day warranty suggests caution for long-term use. Its dual-sided opening enhances accessibility, but verification of roof rack compatibility is recommended before purchase. Compared to the Thule Motion 3, it’s more rugged and potentially better protected from rough conditions but less aerodynamic, which could impact fuel efficiency over long trips. This box is well-suited for drivers who want a durable, hard-shell option that’s simple to access and secure.Pros:- Durable, weather-resistant ABS construction
- Large 12 cubic feet capacity
- Dual-side opening for easy access
- Universal fit with roof rack compatibility
Cons:- Limited warranty period of 30 days
- May require verification for specific roof rack setups
Best for: Outdoor enthusiasts and travelers needing tough, weatherproof protection for their gear
Not ideal for: Those seeking a sleek, aerodynamic profile or longer warranty support, as this box emphasizes durability over aesthetics
- Material:ABS
- Capacity:12 cubic feet (340 L)
- Weight Capacity:165 LBS
- Dimensions:54.3 in L x 31.5 in W x 13.4 in H
- Color:Black
- Opening:Dual-sided
Our verdict“This hard-shell cargo box is a good pick for rugged reliability, especially when durability and weather protection are priorities.”
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Ft
The Thule Pulse 2 M offers a reliable 14 cubic feet of space, making it suitable for weekend trips or daily commutes. Its tool-free, quick-install system with a torque indicator ensures a secure fit, aligning well with the Thule Motion 3’s ease of setup but with a slightly smaller capacity. Its ASA-ABS plastic construction provides weather resistance, though it lacks explicit lock security features, which might be a concern for some users. Compared with the larger Thule Motion 3, it’s more compact and easier to install but offers less capacity for bulky gear. This pick is ideal for drivers who need a straightforward, secure cargo solution for short trips and don’t require maximum volume.Pros:- 14 cubic feet capacity suits weekend gear
- Easy tool-free installation with torque indicator
- Weather-resistant ASA-ABS plastic
- Dual-side opening for access from either side
Cons:- Lacks built-in lock security features
- Potential size limitations for large loads
Best for: Urban drivers and weekend travelers needing a compact, easy-to-install roof box with dependable weather resistance
Not ideal for: Heavy travelers or those needing large capacity, as this box offers less space than the Thule Motion 3 or FIVKLEMNZ
- Capacity:14 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
Our verdict“This cargo box is perfect for quick, secure trips where ease of installation and weather resistance matter most.”
FIVKLEMNZ Car Rooftop Cargo Carrier Waterproof Roof Bag with Accessories
The FIVKLEMNZ waterproof roof bag provides 15 cubic feet of flexible storage with a durable, waterproof design that rivals rigid boxes like the GarveeTech for outdoor use. Its quick installation and universal fit make it suitable for all vehicle types, though the size can be too large for smaller cars, and securing it tightly is essential for high-speed stability. Compared to the soft bag with less accessories, this model includes reinforced straps, a luggage lock, and an anti-slip mat, which enhances security and convenience. It’s well-suited for outdoor enthusiasts who prefer a flexible, waterproof solution that can be easily stored when not in use, but it requires careful securing to prevent movement during travel.Pros:- Waterproof with welded seams and heavy-duty PVC
- 15 cubic feet capacity suitable for multiple items
- Universal fit for all vehicles with quick setup
- Includes accessories for added security
Cons:- Requires careful securing to prevent shifting at high speeds
- Size may be excessive for small cars
Best for: Road trip travelers and outdoor lovers needing water-proof, flexible cargo space for gear and equipment
Not ideal for: Drivers of small vehicles or those unfamiliar with properly securing soft cargo bags at high speeds
- Material:840D PVC
- Capacity:15 cubic feet
- Dimensions:46 x 34 x 17 inches
- Includes:Anti-slip mat, reinforced straps, door hooks, luggage lock
Our verdict“This waterproof roof bag is excellent for outdoor trips requiring flexible, weatherproof cargo space, provided it’s secured properly.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Feet
The Thule Pulse 2 L stands out as the best overall choice due to its combination of user-friendly features and solid construction. Its tool-free installation system with a torque indicator simplifies setup, making it more accessible than the more traditional SportRack Vista XL, which can be heavier and trickier to mount. The Pulse 2 L’s weather-resistant ASA-ABS plastic ensures durability in a variety of conditions, yet it doesn’t specify security features—something to consider if theft prevention is a priority. Compared to the Auto Dynasty, which offers a comparable capacity, the Pulse 2 L’s dual-side opening enhances convenience, especially for quick access on busy trips. Its streamlined design fits most vehicles, but the lack of internal compartments limits organization options. It’s ideal for those seeking a balanced mix of ease, durability, and accessibility.
Pros:- Easy to install with a tool-free system and torque indicator
- Weather-resistant and durable construction
- Accessible from both sides for convenience
Cons:- No specific dimensions provided, limiting fit assessment
- Lacks built-in security or locking features
Best for: Families or travelers who prioritize quick, tool-free setup and easy side access
Not ideal for: Security-conscious users needing integrated locks or security features
- Capacity:16 cubic feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:Not specified
Our verdict“This cargo box suits users who want straightforward installation and reliable weatherproofing without extra security features.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
The Hard Shell Roof Top Cargo Carrier offers a compelling option for those seeking reliable weather resistance and security at a budget-friendly price. Its durable ABS plastic and lockable design give peace of mind, especially compared with the DNA Motoring, which, while similar in capacity, may lack the same level of security features. Its straightforward installation on cross bars makes it accessible for most vehicles, but it’s limited to those with compatible roof rack systems. The absence of internal compartments means organization is basic, and the overall weight could be a challenge for some users. This model makes the most sense for travelers who prioritize waterproofing and security without fuss or complex features.
Pros:- Durable and weather-resistant construction
- Secure lock for peace of mind
- Easy to install on cross bars
Cons:- Limited to vehicles with cross bars
- No internal compartments or padding
- Potentially heavy to handle
Best for: Budget-conscious travelers needing weatherproof, lockable storage
Not ideal for: Users without cross bars or those seeking internal organization features
- Material:ABS plastic
- Capacity:110 lbs
- Dimensions:53 x 34 x 15 inches
- Includes:Cargo roof box, keys, mounting brackets, hardware
Our verdict“This cargo box is ideal for users prioritizing weatherproof security on vehicles equipped with cross bars.”
DNA Motoring Rooftop Cargo Box Carrier, 11 Cubic Feet, Lockable, Heavy Duty, Glossy Black
The DNA Motoring Rooftop Cargo Box makes a strong impression for durability, supporting up to 110 lbs with impact-resistant ABS. Its 11 cubic feet capacity is slightly smaller than some competitors, but its heavy-duty build suits users who need a rugged solution. Compared with the Thule Pulse 2 L, which emphasizes ease of access and streamlined design, the DNA box focuses on toughness and security, making it perfect for rougher conditions. The glossy black finish adds style, but the need for cross bars limits its compatibility. While installation is straightforward, the absence of internal features means organization is basic. This model is best for those who need a secure, impact-resistant carrier for demanding outdoor trips.
Pros:- Large 11 cubic feet capacity
- Durable impact-resistant ABS construction
- Secure lock system for valuables
Cons:- Requires cross bars for installation
- Limited to vehicles with compatible cross bars
- No internal organization features
Best for: Outdoor enthusiasts needing a tough, secure box for rugged environments
Not ideal for: Drivers without cross bars or those seeking internal storage compartments
- Capacity:11 cubic feet
- Max Load:110 lbs
- Dimensions:53″ L x 34″ W x 15″ H
- Finish:Glossy Black
Our verdict“This cargo box is well-suited for users who need a tough, impact-resistant carrier for demanding outdoor adventures.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL earns its spot as the best for large capacity, offering 18 cubic feet of space—more than most in this lineup. Its UV-resistant ABS material ensures long-term durability, and the rear opening design makes access especially convenient for loading and unloading. Compared to the Thule Pulse 2 L, which emphasizes side access, Vista XL’s rear door simplifies access when space is tight or vehicle height is an issue. Its tool-free mounting system speeds setup, but it can be heavy to handle, especially for solo users. Compatibility with specific rack systems requires checking, which might be a limitation for some. This model is ideal for those who need maximum storage and easy rear access for bulky items.
Pros:- Largest capacity at 18 cubic feet
- UV-resistant durable construction
- Rear opening for easy access
Cons:- Heavy to handle alone
- Compatibility depends on rack system
Best for: Outdoor lovers and large families needing maximum storage with straightforward access
Not ideal for: Solo travelers or users with non-compatible rack systems
- Capacity:18 cubic feet
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Max Weight Capacity:100 pounds
Our verdict“This cargo box is best suited for users needing maximum volume and easy rear access, especially for bulky gear.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
The Auto Dynasty Cargo Carrier offers a practical choice for those with cross bars looking for a reliable, weather-resistant storage solution. Its 11 cubic feet capacity is comparable to the DNA Motoring, but it emphasizes universal fit—up to 13-inch wide cross bars—which broadens compatibility. Made from weather-resistant ABS with impact protection, it ensures your gear stays dry and secure. The 14-inch wide loading opening simplifies loading bulky items, but the universal fit may not accommodate all cross bar sizes, and its weight can make handling tricky for solo users. Limited color options are a minor downside, but overall, this model makes sense for outdoor adventurers seeking a sturdy, straightforward carrier that fits most cross bars.
Pros:- Spacious 11 cubic feet capacity
- Weather-resistant and impact-protected
- Easy tool-free installation
Cons:- Universal fit may not suit all cross bars
- Heavy weight may be difficult to handle alone
- Limited color options
Best for: Outdoor families with standard cross bars needing a durable, weatherproof box
Not ideal for: Users with non-standard or very wide cross bars, or those seeking internal compartments
- Dimensions:53″ L x 34″ W x 15″ H
- Capacity:11 Cubic Feet
- Weight Limit:110 lbs
- Material:UV-protected, weather-resistant ABS
Our verdict“This cargo box is a solid pick for outdoor users with standard cross bars seeking durability and weatherproofing.”
SportRack Sidekick Cargo Box
The SportRack Sidekick Cargo Box stands out for its compact design, making it an excellent choice for drivers who need extra storage without sacrificing much roof space. Compared with larger boxes like the Thule Force 3 XL, it offers only 8 cubic feet of capacity, which is ideal for small loads such as camping gear or golf clubs. Its passenger-side opening simplifies loading on tight roads or crowded parking lots, and the secure lock adds peace of mind. However, its limited load capacity of 75 pounds means it’s not suitable for heavy or bulky items, and its smaller size might not fit all vehicle types, especially those with wider roofs. This pick makes the most sense for urban commuters or small families with occasional gear needs.
Pros:- Compact and space-efficient design
- Passenger-side opening for easier access
- Fits most roof rack systems
- Secure lock system
Cons:- Limited capacity for larger loads
- May not fit all vehicle types or wider roofs
Best for: Drivers needing a compact, easy-to-handle cargo box for light loads and limited roof space
Not ideal for: Those regularly transporting heavy or bulky cargo, or owners of very wide vehicles that might not fit this size
- Capacity:8 cubic feet
- Dimensions:54 x 25 x 15.5 inches
- Weight:19.85 pounds
- Load capacity:75 pounds
Our verdict“This cargo box is perfect for small loads and urban use, but not suited for heavy or bulky cargo.”
Thule Force 3 XL Cargo Box
The Thule Force 3 XL excels in durability and ease of use, making it well-suited for active families or frequent travelers. Its larger capacity is ideal for bigger loads compared to the SportRack Sidekick, though it may be bulky for smaller vehicles, requiring some effort during installation. The dual-side access is a significant advantage, allowing easier loading from either side, and the SlideLock system provides a clear indication when the box is securely closed. While its size and weight may pose challenges for some, its solid weather resistance and security features make it a reliable choice for frequent use. Compared to the Thule Force 3 L US, it offers a higher capacity at the expense of increased bulk.
Pros:- Durable, weather-resistant construction
- Easy, secure mounting with safety indicators
- Dual-side access for convenience
- Reliable locking system
Cons:- Bulky for smaller vehicles
- Initial installation can be somewhat effortful
Best for: Active families or outdoor enthusiasts needing a large, secure cargo box for frequent use
Not ideal for: Owners of smaller or compact vehicles who might find this model too bulky to handle or install easily
- Capacity:3 XL
- Mounting System:Quick and secure with indicator
- Access:Dual-side
- Locking System:SlideLock
Our verdict“A robust, high-capacity cargo box ideal for active users who prioritize durability and accessibility.”
Thule Force 3 L US Cargo Box
The Thule Force 3 L US offers a compact profile combined with extensive durability testing, making it a reliable daily companion for active lifestyles. Its 3-liter capacity is quite limited, especially when compared to larger options like the Thule Force 3 XL, and may not suffice for big family trips. Its quick, secure mounting system with safety indicators ensures hassle-free installation, while the dual-side access allows for easier loading and unloading. This model is specifically tested for road safety, providing peace of mind on long drives. However, its small capacity and the need for compatibility checks with certain vehicle models mean it’s better suited for light, everyday cargo rather than bulkier gear.
Pros:- Easy, secure mounting with safety indicators
- Convenient dual-side access
- Extensively tested for durability and safety
Cons:- Limited capacity (3 liters)
- Compatibility may vary with vehicle models
Best for: Daily commuters or individuals with minimal cargo needs who value safety and ease of access
Not ideal for: Large families or those needing to carry bulky or heavy loads regularly
- Capacity:3 liters
- Mounting System:Quick and secure with safety indicator
- Access:Dual-side
- Material:Durable, tested for road safety
Our verdict“A highly durable, safety-focused cargo box perfect for light daily use and smaller cargo loads.”
How We Picked
The products in this roundup were selected based on a combination of factors that matter most to buyers. Performance metrics like durability, waterproofing, and capacity were prioritized, along with usability features such as ease of installation, access, and security. Build quality and weather resistance played a key role, as did overall value, considering both price and features. To ensure relevance, only models suitable for typical vehicle roofs and various trip lengths made the cut. The rankings reflect a balance of these criteria, highlighting options that excel in specific roles but also provide solid all-around performance.Factors to Consider When Choosing Roof Cargo Boxes
Choosing the right roof cargo box involves understanding several key factors beyond just capacity. The type of cargo box—hard shell versus soft bag—affects durability, security, and weather resistance. Consider your vehicle’s roof dimensions and weight limits to ensure proper fit and safe handling. The ease of installation and access can influence your convenience during trips, especially if you frequently load and unload. Price is important, but investing in quality can prevent issues like leaks, wind noise, or damage. Lastly, consider your typical travel needs—whether you prioritize maximum capacity, quick access, or budget-friendly options—when making your decision.Capacity and Size
Capacity determines how much gear you can carry, but larger boxes aren’t always better for every vehicle. Measure your roof’s dimensions and weight limits to avoid overloading or fitting issues. Smaller soft bags can be more flexible and easier to mount on compact vehicles, while larger hard-shell boxes are suited for extended trips with bulky gear. Think about your typical trip length and cargo volume to select a size that balances space with ease of handling.
Material and Weatherproofing
Most roof boxes are either hard shells made from ABS or polycarbonate or soft bags with waterproof fabrics. Hard shells generally provide better protection against impacts, UV, and weather, making them ideal for frequent or long-term use. Soft bags are lighter and more flexible but may be less resistant to heavy rain or snow unless specifically rated waterproof. Consider your climate and storage conditions when choosing the material, as this impacts the longevity and security of your gear.
Ease of Installation and Access
How quickly and securely you can mount and remove your roof box impacts overall convenience. Features like dual-side opening allow access from either side of the vehicle, saving time during loading or unloading. Quick-release mounting systems can make setup easier, especially if you frequently switch between vehicles. Think about your physical space and whether you often travel alone, which can influence your preference for certain mounting mechanisms.
Security and Locking
Locks and security features protect your gear from theft, especially when leaving the vehicle unattended. Many premium models include integrated locks that are tamper-proof, while budget options may lack this feature. Consider whether your trips involve parking in unfamiliar areas or overnight stays—additional security can be worth the investment for peace of mind. Check if locks are easy to operate and resistant to weather conditions.
Price and Value
Price often reflects build quality, capacity, and features, but it’s important to match your budget with your actual needs. Higher-end brands tend to offer better durability, weather resistance, and security, making them suitable for frequent travelers. Budget options can be sufficient for occasional trips and lighter loads but might compromise on longevity or ease of use. Evaluate what features matter most for your trips and choose a model that offers the best value within your budget.
Frequently Asked Questions
Can I install a roof cargo box on any vehicle roof rack?
Most roof cargo boxes are designed to fit standard roof racks, but compatibility depends on your vehicle’s specific setup. Check the dimensions and mounting system of the cargo box against your roof rack’s width and crossbar design. Some models come with adjustable mounts or require specific accessories to fit certain vehicle types. It’s advisable to measure your roof and consult the manufacturer’s specifications to ensure a proper fit and safe installation.
Are soft roof bags as secure and weatherproof as hard-shell boxes?
Soft roof bags can be waterproof if they feature high-quality fabrics and sealed seams, but they generally offer less impact protection than hard-shell boxes. They are more flexible and easier to store when not in use, making them suitable for lighter or less fragile gear. However, for long trips in heavy rain or snow, hard shells provide better protection against the elements and theft. Consider your climate and security needs when choosing between soft and hard options.
How much does a roof cargo box typically weigh, and how does that affect installation?
The weight of a roof cargo box varies widely, from lightweight soft bags around 10-15 pounds to heavy-duty hard shells weighing over 50 pounds. Lighter models are generally easier to install and remove, especially if you often switch vehicles or travel alone. Heavier boxes may offer increased durability and capacity but require more effort and sometimes additional help during mounting. Always check your vehicle’s roof weight limit to avoid overloading.
What features should I prioritize for frequent travelers?
Frequent travelers benefit from features like quick-release mounting systems, dual-side opening for easy access, and high-capacity models to maximize space. Security features such as integrated locks are also important for peace of mind. Durability and weatherproofing are essential if trips involve variable conditions. Investing in a model with these features can streamline your travel experience and protect your gear over the long term.
Is it worth paying more for a premium roof cargo box?
Higher-priced models often provide better build quality, enhanced security, and superior weather resistance, which can justify the extra cost if you travel frequently or carry valuable gear. Premium brands also tend to offer easier installation and access features, reducing hassle during trips. However, for occasional use or light loads, a budget-friendly option can meet your needs adequately. Consider your travel frequency, cargo value, and desired durability when weighing the investment.
Conclusion
For the casual weekend traveler or those new to roof cargo boxes, a budget soft bag like the FIVKLEMNZ Waterproof Roof Bag offers flexible, affordable storage that’s easy to handle. If you seek overall performance and a balanced mix of capacity, security, and ease of use, the Thule Motion 3 stands out as the best choice for most drivers. Heavy-duty users or those with frequent trips should consider the Thule Force 3 XL for its massive capacity and robust construction. For premium buyers, investing in a high-end model with advanced security and weatherproofing ensures long-term durability. Ultimately, your selection should match your vehicle size, trip frequency, and cargo needs.
