The Auto Dynasty Cargo Carrier offers a solid balance between capacity and affordability, with 11 cubic feet of weather-resistant space. Its impact-protected ABS shell and secure lock system make it a good alternative to more premium models like the Thule Pulse 2 L, especially for occasional outdoor use. The easy-to-install, tool-free mounting system simplifies setup, which is ideal for users new to roof cargo solutions. Still, its universal fit may not suit all cross bars, and its weight of over 40 pounds can be cumbersome for solo handling. This pick is best for budget-conscious consumers seeking a reliable, impact-resistant cargo box without bells and whistles.
Pros:- Affordable price point

Garvee Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
The Garvee Rooftop Cargo Box excels in combining aerodynamic design with high capacity, offering 12 cubic feet of storage. Its shape minimizes drag and noise, making it a smart option compared with bulkier alternatives like the Thule Motion 3. Its durable, UV-resistant ABS shell and dual-sided access provide convenience and weather protection, perfect for frequent travelers who want a sleek, functional carrier. The need to verify roof rack compatibility and its limited one-year warranty are notable tradeoffs, especially compared to premium brands with longer guarantees. This product is best suited for drivers who prioritize fuel efficiency and extra space without sacrificing durability.
Pros:- Aerodynamic shape reduces fuel consumption
- Weather-resistant and UV-protected
- Dual-sided opening for easy access
- Includes keys and straps for security

SportRack Sidekick Cargo Box
The SportRack Sidekick is tailored for those with limited roof space or lighter load needs, offering just 8 cubic feet of storage. Its compact dimensions and passenger-side opening make it easy to load, especially for quick trips or small gear like golf clubs or camping supplies. Compared to larger, hard-shell options like the GarveeTech, this is a more streamlined choice for urban or short-distance use. Its lower load capacity of 75 pounds limits its use for heavier equipment, and it might not fit all vehicle types due to its size. This product is best for casual users who prioritize space-saving design over maximum capacity.
Pros:- Compact and space-efficient design
- Passenger-side opening simplifies loading
- Fits most roof rack systems
- Lightweight for easy handling
Cons:- Limited load capacity for larger or heavier gear
- Smaller size may not meet all cargo needs
Best for: Car owners with small or medium roof racks needing a compact, easy-to-use cargo solution for light loads.
Not ideal for: Travelers carrying heavy or bulky gear that exceeds 75 pounds or requiring maximum storage capacity.
- Capacity:8 cubic feet
- Dimensions:54 x 25 x 15.5 inches
- Weight:19.85 pounds
- Load Capacity:75 pounds
Our verdict“Best suited for light loads and small vehicles where space efficiency and ease of use are priorities.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ Soft Roof Bag offers an impressive 21 cubic feet of flexible, waterproof storage, making it ideal for travelers with extensive gear or multiple suitcases. Its high-frequency welded seams and durable 840D PVC material ensure complete waterproofing, outperforming many rigid carriers in heavy rain or snow. The soft design allows for easier storage when not in use, unlike bulky hard shells like the GarveeTech. However, its bulkiness when filled can make installation and handling more challenging, and the stiff material may be uncomfortable for some users. This bag is best for those seeking maximum capacity, full weather protection, and flexible storage options.
Pros:- High capacity for multiple suitcases and gear
- Excellent waterproofing with welded seams
- Universal fit for all vehicle types
- Includes comprehensive travel accessories
Cons:- Bulky to store when not in use
- Stiff material can be difficult to handle

Not ideal for: Users with limited storage space for bulky bags or those who prefer rigid, easy-to-clean carriers.
- Capacity:21 cubic feet
- Dimensions:52 x 40 x 18 inches
- Material:840D PVC

- Includes:Anti-slip mat, luggage lock, straps, hooks

Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Ft
The Thule Pulse 2 M stands out for its combination of capacity and user-friendly features, making it a top choice for most travelers. Its 14 cubic feet of space comfortably accommodates gear for family trips or weekend adventures, outperforming smaller options like the SportRack Vista XL, which, despite its larger 18 cubic feet capacity, offers less streamlined installation. The tool-free mounting system with a torque indicator simplifies setup and ensures a secure fit, while weather-resistant ASA-ABS plastic protects contents from the elements. However, the lack of integrated lock security and potential vehicle size limitations mean it’s not ideal for those needing high-security or very large-capacity solutions. Overall, this model is perfect for drivers seeking a reliable, easy-to-use cargo box that balances size and convenience.
Pros:- Large 14 cubic feet capacity suits most travel needs
- Easy tool-free installation with torque indicator
- Weather-resistant and durable ASA-ABS plastic
Cons:- No integrated lock security features
- Potential size limitations on certain vehicles
Best for: Families and casual travelers who want a durable, mid-sized cargo box with easy installation.
Not ideal for: Owners of very large vehicles or those needing high-security locking, since it offers no dedicated lock feature and has size restrictions.
- Capacity:14 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
Our verdict“A well-rounded choice for users seeking a dependable, mid-capacity cargo box with straightforward setup.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Feet
Compared with the Pulse 2 M, the Thule Pulse 2 L offers an additional 2 cubic feet of space, making it a better fit for those with more gear or larger luggage. Its streamlined, dual-side opening design simplifies access, especially when parked on busy streets. While it shares the same easy, tool-free installation and weather-resistant ASA-ABS construction as the smaller model, it lacks specific dimensions and weight details, which could make fitting it onto certain vehicles more challenging. Like the Pulse 2 M, it doesn’t mention lock features, so security may be a concern for some users. This pick is ideal for those needing extra space without sacrificing ease of use or weather protection, but it’s less suited for owners who need built-in security or detailed sizing info.
Pros:- Additional 2 cubic feet of storage for more gear
- Easy to install with tool-free setup and torque indicator
- Dual-side access for convenience
Cons:- Lack of detailed dimensions and weight info
- No built-in lock security features
Best for: Travelers needing a slightly larger cargo capacity with quick access and weather resistance.
Not ideal for: Those requiring detailed fit specifications or lock security, as this model lacks lock features and detailed dimensions.
- Capacity:16 cubic feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
Our verdict“A solid upgrade for users wanting more space with straightforward installation and weather resistance.”
Thule Force 3 L US Cargo Box
The Thule Force 3 L US emphasizes durability and security, with a sleek design suited for frequent use. Its 3-liter capacity is quite limited compared to the other options, like the SportRack Vista XL, which offers 18 cubic feet—more suitable for bulky outdoor gear or multiple suitcases. The SlideLock system provides a quick, secure closure with a dedicated locking mechanism, making it ideal for daily commutes or active travelers who value security and ease. The quick mounting system with safety indicators enhances convenience and safety. However, the small capacity makes it less suitable for large families or long trips requiring significant cargo space. This model makes sense for users prioritizing security, frequent access, and a stylish, robust appearance, but it’s not for those with large storage needs.
Pros:- Secure SlideLock system with safety indicator
- Easy, quick mounting with safety features
- Stylish, durable construction tested for safety
Cons:- Limited capacity of just 3 liters
- Designed for specific vehicle compatibility
Best for: Active individuals or daily commuters needing a secure, stylish cargo box for smaller loads.
Not ideal for: Large families or those needing substantial cargo space, as it’s limited to only 3 liters.
- Capacity:3 liters
- Mounting System:Quick and secure with safety indicator
- Locking System:SlideLock
- Material:Durable, tested for road safety
Our verdict“An excellent choice for security-conscious users needing a small, reliable cargo box for daily use.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This universal ABS plastic cargo box offers versatile compatibility and weather protection, making it a practical option for travelers with various vehicle types. Its 110-pound capacity and sizable dimensions (53 x 34 x 15 inches) provide ample space for luggage, surpassing smaller soft bags or soft-sided carriers. Unlike soft bags, it provides a firm shell that shields contents from rain and debris, but it’s heavier and more cumbersome to handle during installation. Its lockable design adds security, yet it’s limited to vehicles equipped with cross bars, which may exclude some owners. For users needing a dependable, weatherproof hard shell with straightforward installation, this model fits well; however, it’s less suitable for vehicles without cross bars or for those seeking internal compartments.
Pros:- Durable, weather-resistant ABS construction
- Secure lock for peace of mind
- Easy to install on cross bars
Cons:- Heavy and potentially cumbersome to handle
- Limited to vehicles with cross bars
Best for: Travelers seeking a weatherproof, durable hard shell carrier compatible with cross bars and requiring reliable protection from the elements.

- Material:ABS plastic
- Capacity:110 lbs
- Dimensions:53 x 34 x 15 inches
- Includes:Keys, mounting brackets, hardware
Our verdict“A solid, weatherproof hard shell option for travelers with cross bar-equipped vehicles needing reliable outdoor protection.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL offers a generous 18 cubic feet of storage, making it an appealing choice for those who need maximum capacity. Its UV-resistant ABS material ensures durability against sun exposure, and the rear-opening design simplifies access to gear, especially when parked at the back of the vehicle. The tool-free mounting system enhances convenience for quick setup and removal. Compared with the Thule options, the Vista XL provides more space but may lack some of the sleek aesthetics or advanced security features. Its weight and specific rack compatibility can pose challenges for some users. This cargo box makes sense for outdoor enthusiasts or large families needing substantial storage, but it may be less suitable for lightweight or smaller vehicle owners.
Pros:- Large 18 cubic feet capacity for extensive gear
- Durable UV-resistant ABS material
- Rear opening for easy access
Cons:- Heavy to handle during installation
- Fits only specific rack systems; check compatibility

Thule Force 3 XL Cargo Box
The Thule Force 3 XL stands out for its combination of durability, security, and user-friendly features. Its sturdy, weather-resistant design makes it suitable for all seasons, and the dual-side access allows for easier loading compared to the single-opening models like the GarveeTech Carrier. The quick-mount system with safety indicators simplifies installation, though it can be bulky for smaller vehicles, requiring extra space and effort. Compared to the FIVKLEMNZ Car Roof Bag, it offers more security and a more rigid structure, but at the cost of increased weight and size. This pick is ideal for families or outdoor enthusiasts who prioritize secure, reliable storage without sacrificing convenience, even if they need to allocate more space for installation.Pros:- Durable, weather-resistant construction for all-season use
- Easy and secure mounting system with safety indicators
- Dual-side access simplifies loading and unloading

- Dimensions:Not specified in brief
Our verdict“This cargo box is best suited for users who value durability, security, and convenience over compactness.”
Thule Motion 3 Rooftop Cargo Box
The Thule Motion 3 excels in combining sleek design with practical space, making it perfect for those who want to reduce drag and improve fuel economy. Its aerodynamic shape sets it apart from bulkier options like the GarbeeTech Carrier, helping to minimize wind noise and resistance. The quick-mount system and torque indicator facilitate installation, but some users report that setup can be less intuitive initially. While it offers ample interior space, it lacks detailed info on accessory compatibility, which might be a concern for customization. This model makes the most sense for frequent travelers who value efficiency and style, even if they are willing to pay a premium for its design.Pros:- Aerodynamic design reduces drag and wind noise
- Easy to mount with quick-mount system and torque indicator
- Spacious interior for large and bulky items
- Limited lifetime warranty adds peace of mind
Cons:- Lack of detailed accessory compatibility info

- Model Number:197074566126
- Warranty:Limited Lifetime
- Mounting System:Quick-mount with torque indicator

Our verdict“This pick is best for users prioritizing efficiency and large capacity in a sleek, aerodynamic package.”
DNA Motoring Rooftop Cargo Box Carrier, 11 Cubic Feet
The DNA Motoring 11 Cubic Feet offers a large, impact-resistant ABS construction that balances durability with affordability. Its 11 cubic feet capacity makes it suitable for medium-sized loads, especially compared to the smaller Thule Force 3 XL. However, it requires cross bars for installation, which could add to the overall cost and complexity for owners without existing roof rack systems. Its glossy black finish is attractive but may show scratches more easily. While it provides good security with a lockable system, the lack of included mounting hardware means additional investment might be necessary. This model appeals most to budget-conscious buyers looking for a secure, impact-resistant cargo box, provided they have cross bars already installed.Pros:- Large 11 cubic feet storage capacity
- Durable impact-resistant ABS construction
- Secure lockable system for valuables
- Easy to install on vehicles with cross bars
Cons:- Requires existing cross bars for installation
- No included mounting hardware, adding to setup complexity

- Max Load:110 lbs
- Dimensions:53″ L x 34″ W x 15″ H
- Material:Impact-resistant ABS
- Finish:Glossy Black
Our verdict“This cargo box suits buyers who want a durable, impact-resistant storage option at a more affordable price point with existing cross bars.”
FIVKLEMNZ Car Rooftop Cargo Carrier Waterproof Roof Bag with Accessories
The FIVKLEMNZ Roof Bag provides a versatile, soft-sided option with 15 cubic feet of capacity, making it ideal for road trips and outdoor adventures. Its waterproof 840D PVC with welded seams ensures belongings stay dry, outperforming rigid boxes in heavy rain. Designed for universal fit, it can be installed on any vehicle with or without roof racks, unlike rigid carriers that require cross bars. The included accessories, like reinforced straps and an anti-slip mat, add to its convenience. However, securing the bag tightly is essential to prevent movement at high speeds, and its size might be impractical for small vehicles. This soft roof bag is perfect for flexible, large-capacity storage, but requires careful setup.Pros:- Waterproof and heavy-duty construction keeps gear dry
- Large capacity suitable for multiple suitcases
- Universal fit with quick installation
- Includes multiple accessories for secure attachment
Cons:- Requires careful securing to prevent movement at high speeds
- Size may be too large for small vehicles
Best for: Road trip enthusiasts and outdoor adventurers needing flexible, waterproof storage for all vehicle types.

- Material:840D PVC
- Capacity:15 cubic feet

- Includes:Anti-slip mat, reinforced straps, door hooks, luggage lock, storage bag
Our verdict“This soft roof bag is well-suited for users seeking flexible, waterproof storage for large loads, willing to invest time in proper securing.”
GarbeeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12-14 Cubic Feet
The GarbeeTech Carrier offers a rugged, waterproof hard shell with dual-sided opening, making access easy from either side. Its 12-14 cubic feet capacity suits larger loads and the durable ABS construction provides UV resistance and impact protection. It compares favorably to the Thule Force 3 XL in toughness but may be heavier and bulkier, which could challenge installation on smaller vehicles. Compatibility with roof racks is a plus, but verification is recommended due to limited customer feedback. This model appeals to those needing a tough, weatherproof hard shell that’s easy to access from either side, though the size and weight might be drawbacks for some.Pros:- Durable, waterproof ABS shell with UV resistance
- Dual-side opening for ease of access
- High weight capacity of 165 lbs

- Material:ABS plastic
- Capacity:12-14 cubic feet
- Dimensions:54.3″L x 31.5″W x 13.4″H / 62.2″L x 31.5″W x 13.4″H
- Weight Capacity:165 lbs
- Color:Black
Our verdict“This cargo box is best for users needing a tough, weatherproof, dual-access hard shell on larger or heavy-duty vehicles.”
How We Picked
Products were selected based on a combination of capacity, build quality, ease of installation, weatherproofing, and overall value. We prioritized models with proven durability and innovative features like dual-side opening and secure locking mechanisms. Our evaluation considered user-friendly designs suited for various vehicle types, as well as the balance between cost and performance. The ranking reflects which options best serve different needs—from casual travelers to frequent road trippers—while emphasizing long-term usability and security.Factors to Consider When Choosing Roof Cargo Boxes
Choosing the right roof cargo box involves understanding several key factors that influence performance, convenience, and value. By considering these aspects, you can avoid common pitfalls like overpaying for features you don’t need or selecting a model incompatible with your vehicle. The following sections highlight the main criteria to keep in mind before making your purchase.Capacity and Size
Capacity is often the most noticeable factor. Smaller boxes around 8-12 cubic feet suit occasional trips or smaller vehicles, while larger options exceeding 16 cubic feet are better for families or long trips. Keep in mind that bigger boxes add weight and might impact your vehicle’s aerodynamics, so measure your roof’s available space carefully. Overloading a box can also compromise safety and longevity, so choose a size that matches your typical cargo volume.
Material and Durability
Hard-shell boxes tend to withstand weather elements better, offering superior waterproofing and security. Soft roof bags are lighter and easier to install but usually lack the same level of protection against rain, snow, or impact. If you frequently travel in harsh conditions, investing in a rugged, weatherproof hard shell makes sense. For occasional use or short trips, a well-made soft bag could suffice, saving weight and simplifying installation.
Ease of Installation and Access
Look for models that feature straightforward mounting systems compatible with your roof rack. Dual-side opening options significantly enhance convenience, especially in tight parking situations, allowing access from either side without repositioning the vehicle. Consider also how easily you can load and unload your cargo; a low-profile box reduces strain and makes handling easier. Some designs include quick-release mechanisms or integrated locks for added security.
Aerodynamics and Noise
Roof boxes can impact your vehicle’s aerodynamics, affecting fuel efficiency and creating noise during travel. Models with sleek, streamlined shapes tend to produce less wind resistance and noise, making long drives more comfortable. Thicker materials or box designs that protrude sharply may increase drag and sound. If fuel economy or quiet rides are priorities, pay attention to the shape and mounting position of the cargo box.
Price and Long-Term Value
Higher-end models from reputable brands often justify their premium with better materials, security features, and durability. Cheaper options might save money upfront but could require replacement sooner or lack key features like weatherproofing or sophisticated locks. Balance your budget with your intended usage frequency; investing in a durable, feature-rich box makes sense for frequent travelers, while occasional users might prefer more affordable, basic models.
Frequently Asked Questions
Can I install a roof cargo box on any vehicle?
Most roof cargo boxes are designed to fit standard roof racks, but compatibility depends on your vehicle’s roof type and rack system. Before purchasing, verify your roof’s weight capacity and mounting points. Some vehicles may require additional adapters or crossbars. A properly installed box that matches your roof’s specifications will ensure safety and ease of use during travel.
Are soft roof bags waterproof enough for winter trips?
Many soft roof bags are marketed as waterproof, but their protection level varies with material quality and design. High-quality models with sealed seams and water-resistant fabrics can handle winter conditions reasonably well, but they are generally less reliable than hard-shell boxes in heavy snow or rain. For frequent winter trips, a hard-shell cargo box provides better peace of mind regarding weatherproofing.
How do I prevent a roof cargo box from making noise during driving?
Noise often results from poor aerodynamics or loose mounting. Choosing a streamlined, low-profile design reduces wind resistance and noise. Ensure your cargo box is securely mounted with tight-fitting clamps or locks, and avoid overloading it, which can cause vibrations. Some models come with aerodynamic features or rubber seals that help minimize wind noise, making your ride quieter.
What is the best way to secure my cargo in the box?
Most cargo boxes come with built-in locks or latches, but for added security, consider using cargo straps or bungee cords inside. Properly distributing weight and securing items prevent shifting during transit, reducing noise and risk of damage. Always lock the box when unattended, especially if you’re parking in public areas, to deter theft and ensure your cargo remains safe.
How should I maintain my roof cargo box for longevity?
Regular cleaning with mild soap and water maintains the appearance and prevents buildup of dirt and grime that can degrade materials. Check mounting hardware and locks periodically to ensure they remain tight and functional. For hard-shell boxes, inspect for cracks or damage, and apply weatherproofing treatments if recommended by the manufacturer. Proper maintenance extends the lifespan of your cargo box and keeps it performing reliably.
