Rooftop Cargo Box Carrier, 17 Cu ft Hard Shell Rooftop Cargo Carrier – Dual-Side Opening, Universal Fit, Waterproof ABS, 165Lbs Capacity with Secure Straps & Keys
This hard-shell cargo box shines for its combination of security and aerodynamic design, making it a reliable choice for a wide range of vehicles. Compared to the soft-sided options like the Asinking Car Rooftop Cargo Carrier Bag, it offers better protection against weather and impacts, especially on rough roads. Its dual-side opening simplifies loading from either side, a feature not available in all models. The inclusion of lockable keys adds a layer of theft prevention, crucial for long stops. However, it’s important to verify roof rack compatibility, as some vehicles may require additional adapters. Its 17 cubic feet capacity balances enough space for essentials without becoming overly bulky, but it might fall short for very large families or extensive gear. Overall, this box stands out for travelers seeking a secure, aerodynamic, and fairly spacious solution without sacrificing ease of use.
Pros:- Secure locking system with keys ensures theft prevention
- Aerodynamic shape reduces wind noise and improves fuel efficiency
- Quick and easy installation with all necessary components
Cons:- Check roof rack compatibility before purchase
- Capacity may be insufficient for very large groups or extensive gear
Best for: Families or outdoor enthusiasts needing a secure, weatherproof cargo solution with moderate capacity.
Not ideal for: Owners of very large vehicles or those with extremely high volume needs, as capacity may be limiting.
- Capacity:17 cubic feet
- Material:ABS
- Weight Capacity:165 lbs
- Opening:Dual-side

Our verdict“This cargo box is ideal for travelers wanting a secure, aerodynamic, and easy-to-install solution for moderate gear loads.”
Asinking Car Rooftop Cargo Carrier Bag 21 Cubic Feet Waterproof
Compared with hard-shell options like the Rooftop Cargo Box Carrier, the Asinking Cargo Carrier Bag offers a larger capacity of 21 cubic feet, making it ideal for those who pack extensively or need more flexible loading space. Its soft, waterproof material allows for easy storage when not in use and can fit on vehicles without crossbars, unlike rigid boxes that often require specific mounting systems. Security features such as a lock and anti-slip mat provide peace of mind, but the soft shell design may be less protective against impacts or heavy rain in extreme conditions. Additional straps may be needed for very heavy or bulky loads, and installation on certain vehicle types could be more complicated. This model makes sense for budget-conscious travelers who prioritize capacity and flexibility over rigid structure.
Pros:- Waterproof and tearproof construction protects cargo
- Large 21 cubic feet capacity maximizes roof space
- Universal fit allows use on all vehicle types
Cons:- May require additional straps for very large loads
- Soft shell may be less durable for heavy or sharp-edged items
- Installation can be challenging on some vehicles
Best for: Budget-conscious road trippers seeking maximum capacity and easy storage on all vehicle types.
Not ideal for: Those planning to carry fragile or heavy items in rough weather, since the soft shell offers less impact protection.
- Capacity:21 cubic feet
- Material:900D PVC tarpaulin
- Dimensions:52″ L x 40″ W x 18″ H
- Includes:Anti-slip mat, luggage lock, security hooks, storage bag
Our verdict“This cargo bag is best suited for budget-minded travelers needing flexible, waterproof storage that fits almost any vehicle.”
Rooftop Cargo Box, 13 Cubic Feet, Black, Weather-Resistant Hard-Shell with Security Locks
This 13-cubic-foot hard-shell cargo box balances moderate capacity with weather resistance, making it well-suited for family trips. Its impact-resistant materials, including ABS and PMMA, provide solid protection against rain and road debris, similar to the Garvee Rooftop Cargo Box Carrier but with a slightly smaller capacity. Dual-sided access allows for easier loading from either side, a feature not always present in compact models. Installation might require some adjustment depending on crossbar spacing, and its black color limits aesthetic options. While not as large as the Asinking Bag, its rigid shell offers more protection for fragile items and in harsh weather conditions. This box makes the most sense for families prioritizing weatherproofing and security over maximum volume.
Pros:- Weather-resistant and impact-resistant construction
- Dual-sided access for easy loading
- Secure locking system for valuables
Cons:- Installation may require adjustments for different crossbars
- Limited color options (only black)
Best for: Families needing a weatherproof, secure, and impact-resistant cargo solution for road trips.
Not ideal for: Travelers requiring maximum space or carrying very bulky gear, since capacity is limited to 13 cubic feet.
- Capacity:13 cubic feet
- Weight Capacity:130 lbs
- Dimensions:56″ L x 30″ W x 13.7″ H
- Material:Impact-resistant ABS and PMMA
Our verdict“This box is perfect for families seeking reliable weatherproofing and security for moderate gear loads on road trips.”
DUMOS Car Roof Bag Cargo Carrier Waterproof 20 Cubic Feet
Compared to hard-shell options like the Garvee Cargo Box, the DUMOS Roof Bag provides a generous 20 cubic feet of waterproof storage, ideal for extensive gear or camping supplies. Its heavy-duty PVC construction withstands harsh weather, and the reinforced straps and combination lock add security, especially useful during extended stops. The soft-shell design makes it lighter and more flexible for storage when not in use, but it may require roof racks or crossbars for optimal attachment, which could be a drawback for some vehicles. While not as impact-resistant as rigid boxes, its large capacity and waterproof nature make it a smart choice for outdoor adventurers. This bag suits those prioritizing maximum space and weatherproofing over structural rigidity.
Pros:- Waterproof and tearproof for all weather conditions
- Large 20 cubic feet capacity maximizes roof space
- Reinforced straps and lock prevent cargo shifting and theft
Cons:- May require roof racks or crossbars for proper fit
- Soft shell offers less impact protection
- Installation can be tricky on some vehicle types

- Waterproof:Yes
- Includes:Anti-slip mat, luggage lock, security hooks, reinforcement strips
Our verdict“This cargo carrier excels for outdoor trips requiring large, waterproof, and secure storage, especially when vehicle compatibility is met.”
Garvee Rooftop Cargo Box Carrier, 13.5 Cubic Feet, Dual-Side Opening, Black
The Garvee Roof Cargo Box offers a balance of capacity, security, and aerodynamic design, making it suitable for road trips where fuel economy matters. Its 13.5 cubic feet space is comparable to the Weather-Resistant Hard Shell Box, but with a focus on reducing wind noise and drag, which can contribute to better fuel efficiency. The dual-side opening simplifies loading, especially when parking is tight. Its UV-resistant ABS construction ensures durability over time, though it’s somewhat limited in capacity for larger groups. The weight limit of 135 pounds makes it manageable to install but still sturdy enough for most gear. This pick makes the most sense for drivers prioritizing a sleek profile and security, rather than maximum volume.
Pros:- Waterproof and UV-resistant for all weather conditions
- Dual-side opening for easy loading from either side
- Aerodynamic shape reduces wind noise and fuel consumption
Cons:- Requires vehicle with roof racks or crossbars for installation
- Limited to 13.5 cubic feet capacity

Our verdict“This roof box suits drivers looking for a sleek, secure, and weatherproof solution that minimizes fuel costs and wind noise.”
Auto Dynasty Heavy Duty Hard Shell Roof Top Mount Car Storage Luggage Box, 53 x 34 x 15 Inches, 11 Cubic Feet, 110 lbs Capacity, Tool-Free Install
This cargo box stands out for its combination of generous capacity and robust construction. With 11 cubic feet of storage and a 110-pound weight limit, it offers ample space for family gear, especially when compared to the smaller SportRack Vista XL, which provides only 18 cubic feet but with a potentially easier rear access. Its weather-resistant ABS shell effectively protects belongings from rain, snow, and impacts, making it a reliable choice for outdoor adventures. The tool-free mounting simplifies installation, but it requires compatible cross bars no wider than 13 inches—something to verify before purchase. While the hard shell design offers superior protection, it can be heavier and more challenging to store when not in use. This pick is ideal for those seeking a durable, weatherproof solution with significant capacity, willing to handle a slightly more complex setup.
Pros:- Spacious 11 cubic feet capacity for large loads
- Secure lock system enhances security
- Weather-resistant and impact-protected design
Cons:- Requires checking cross bar dimensions before purchase
- May be difficult to install without tools initially
Best for: Families or outdoor enthusiasts needing a sturdy, weatherproof hard shell box for extensive gear and long trips
Not ideal for: Casual drivers or those with limited roof bar dimensions, as installation may be tricky and compatibility limited
- Dimensions:53 x 34 x 15 inches
- Capacity:11 Cubic Feet
- Weight Limit:110 Pounds
- Material:UV-protected, weather-resistant ABS
- Mounting Compatibility:Fits cross bars up to 13 inches wide
Our verdict“This cargo box is best suited for users prioritizing durability and protection over ease of installation, especially on larger family trips.”
MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks
The MIDABAO cargo bag offers a hefty 20 cubic feet of space, making it ideal for those who need maximum volume without the bulk of a hard shell. Compared with the hard-sided options like the Auto Dynasty box, this soft carrier provides greater flexibility to fit various vehicle shapes and roof configurations. Its PVC-coated waterproof fabric keeps contents dry even in heavy rain, and the included anti-slip mat stabilizes the load during travel. However, soft carriers can be less protective against impacts and may require careful fastening to prevent movement. Fit can also vary depending on roof rack design, and some users might find the straps less intuitive to secure. This choice suits travelers seeking high capacity with easy storage and weatherproof features, but not those prioritizing impact protection or rigid security.
Pros:- Huge 20 cubic feet capacity for extensive gear
- Waterproof PVC fabric for all-weather protection
- Easy to install and store with flexible design
Cons:- May not fit all roof rack configurations perfectly
- Soft material is less impact-resistant than hard shells
Best for: Large families or campers needing maximum storage volume with flexible fit for different vehicles
Not ideal for: Drivers who want hard-sided security or are concerned about impact protection, as soft material offers less defense
- Capacity:20 Cubic Feet
- Dimensions:51.1” x 39” x 17”
- Material:PVC-coated fabric
- Includes:Anti-slip mat, 6 straps, 2 3M straps
- Fits:All cars with or without roof rack
Our verdict“This soft rooftop carrier excels for users who prioritize volume and weatherproofing over rigid impact protection and perfect fit on every vehicle.”
Rooftop Cargo Carrier Waterproof Car Roof Bag with Protective Mat, 16 Cubic Feet Storage
This 16-cubic-foot waterproof roof bag offers a reliable weatherproof solution, comparable in capacity to the Car Rooftop Cargo Carrier Bag but with a focus on universal compatibility. Its nylon fiber construction with heat-welded seams ensures protection against rain and snow, making it suitable for all-season trips. The included anti-slip mat and secure straps help prevent movement during driving, although the straps may require adjustment for a snug fit, especially on vehicles without roof racks. Unlike rigid boxes such as the Auto Dynasty model, this bag is lightweight and easy to store when not in use, but it provides less impact resistance. It’s an excellent option for travelers who want a flexible, waterproof cargo solution that fits most vehicles, but not for those needing high impact protection or security locks.
Pros:- Reliable waterproof zipper and seam construction
- Universal compatibility with various vehicle types
- Easy to install and store
Cons:- Requires separate purchase of door hooks for some vehicles
- Straps may need frequent adjustment for perfect fit
Best for: Travelers seeking an easy-to-use, waterproof, and adaptable cargo solution for vehicles with or without roof racks

Our verdict“This waterproof roof bag is well-suited for users who need flexible, weatherproof cargo capacity without the bulk of a hard shell, especially on diverse vehicle types.”

The Car Rooftop Cargo Carrier Bag offers a sturdy 15 cubic feet of storage with heavy-duty 840D PVC fabric, standing out for its durability and waterproof performance. Compared to softer options like the MIDABAO, this bag’s reinforced seams and abrasion-resistant material provide better impact resistance and longevity, making it suitable for rougher travel conditions. Its adjustable straps and included accessories simplify installation on various vehicles, but securing the bag tightly is essential to prevent movement during high-speed drives. The stiff fabric may be stiff when new, and heavier than soft carriers, requiring more effort to handle and store. This pick is perfect for those who need maximum durability and waterproofing, even if it means sacrificing some flexibility and ease of handling.
Pros:- Heavy-duty 840D abrasion-resistant fabric for durability
- Reinforced seams for extra waterproof protection
- Easy to install with adjustable straps and accessories
Cons:- May require careful securing to prevent movement
- Heavy and stiff when new, less flexible to handle
Best for: Adventurers and frequent travelers seeking a rugged, waterproof cargo solution for rough road conditions

- Material:840D abrasion-resistant PVC
- Capacity:15 Cubic Feet
- Waterproof:Yes
- Includes:Anti-slip mat, door hooks, extra straps, luggage lock
Our verdict“This heavy-duty cargo bag is ideal for users prioritizing ruggedness and waterproofing in demanding travel environments, accepting the tradeoff of weight and stiffness.”
SportRack Vista XL Rear Opening Cargo Box, Black
The SportRack Vista XL offers 18 cubic feet of storage with a rear-opening design, making access easier in tight spaces compared to side-opening hard shells like the Auto Dynasty. Its UV-resistant ABS shell provides good protection against the elements and impacts, although the rear opening can be less convenient if space is limited behind the vehicle. Compared with other rear-opening options, its size strikes a good balance for larger loads without excessive bulk. The tool-free mounting system allows quick installation and removal, but the maximum weight capacity of 100 pounds might limit heavier cargo. This model is best suited for users who prioritize quick access and large capacity, particularly in situations where front access isn’t feasible.

- Tool-free installation and removal

- Dimensions:63 x 38 x 19 inches
- Max Weight Capacity:100 pounds
- Mounting Hardware:Tool-free
Our verdict“This rear-opening cargo box is ideal for users who need quick access to large loads on a variety of roof racks, accepting some space limitations behind the vehicle.”
FIVKLEMNZ 21 Cubic Feet Waterproof Car Rooftop Cargo Carrier Roof Bag
This roof bag stands out for its combination of size and waterproof durability, making it ideal for travelers who need to maximize storage without sacrificing weather protection. Compared to the Sailnovo bag, it offers a slightly larger capacity at 21 cubic feet, but may be bulkier to store when not in use. Its durable 840D PVC material ensures luggage stays dry in heavy rain, and its universal fit means it works on most vehicles, even those without roof racks. The reinforced straps and hooks make installation straightforward, but proper securing is essential to prevent shifting. While its large capacity is a major plus, it can be cumbersome to handle and store. Wind noise at high speeds is a common issue, especially on open roads. Overall, this bag is best suited for road trip enthusiasts needing significant cargo space who are willing to manage its bulk during storage.
Pros:- Highly waterproof and durable, suitable for all weather conditions
- Generous capacity to hold multiple suitcases and gear

Compared with soft-sided options like the Sailnovo bag, the JEGS hard-shell carrier offers superior weatherproofing and security, making it a strong choice for travelers prioritizing protection and ease of access. Its 18 cubic feet capacity is slightly smaller but still ample for most road trip essentials. The aerodynamic design reduces drag, which can improve fuel efficiency over long distances—an edge over bulkier soft bags. The locking system with four corner locks and a front latch enhances security, especially when leaving the car unattended. However, its limited rear opening access may require more effort to reach gear, and it’s heavier, which could be a concern for those with less robust roof racks or weaker lifting capacity. Ideal for drivers seeking a durable, secure, and fuel-efficient cargo solution, but less suited for quick access or lightweight needs.
Pros:- Secure locking system keeps gear safe from theft
- Aerodynamic design enhances fuel economy
- Weatherproof and durable HDPE construction
Cons:- Limited rear access can make retrieving items inconvenient
- Heavier weight may require stronger roof rack support
Best for: Travelers who prioritize security and aerodynamic efficiency on longer trips

This soft-sided cargo bag is built from heavy-duty 840D waterproof fabric, offering robust weather protection comparable to the FIVKLEMNZ bag but with a more flexible profile. Its 21 cubic feet capacity makes it suitable for extensive gear, including tents and large luggage. Reinforced seams and waterproof zippers enhance durability and protection, especially during harsh weather. The adjustable straps and anti-slip mat help secure the bag tightly, but careful installation is needed to prevent shifting—similar to the FIVKLEMNZ model. Compared to rigid boxes, this bag is more flexible to store when not in use but might be less stable during high-speed travel. It’s perfect for those who need heavy-duty waterproof storage that can adapt to different vehicle types, yet the stiff material can be less forgiving during installation.
Pros:- Durable, waterproof, and weather-resistant fabric
- Large capacity to carry tents, luggage, and camping gear
- Easy to install with adjustable straps and anti-slip mat
Cons:- Heavy-duty fabric can be stiff and less flexible

- Material:840D abrasion-resistant PVC fabric
- Capacity:21 cubic feet
- Waterproof:Yes
- Includes:Anti-slip mat, storage bag, door hooks, extra straps, luggage lock
Our verdict“This heavy-duty waterproof roof bag provides a flexible, large-capacity solution suitable for rugged trips, though its stiffness and installation demands are considerations.”
How We Picked
This lineup was curated by evaluating each product on capacity, build quality, ease of installation, weatherproofing, security features, and value for money. Priority was given to models that balance durability with user-friendly features like dual-side opening and quick mounting. We also considered customer feedback on long-term reliability and the practicality of accessories such as straps and locks. The ranking reflects a combination of these factors, emphasizing models that perform well across diverse road trip scenarios while offering a range of price points to suit different budgets.Factors to Consider When Choosing Roofcargo Box For Road Trips
Choosing the right roofcargo box for road trips involves more than just capacity. It’s essential to consider how well the box withstands weather conditions, how easy it is to install and access, and whether it fits your vehicle. Understanding these factors helps avoid common pitfalls like overloading, poor security, or incompatible sizes that can compromise safety and convenience on the road.Capacity and Size
Assess your luggage volume and ensure the cargo box can handle it comfortably without overloading your vehicle. Bigger isn’t always better—consider your roof’s weight limits and how the box’s size affects aerodynamics and fuel efficiency. Look for models that strike a balance between ample space and manageable dimensions, especially if you frequently switch vehicles or storage locations.
Weatherproofing and Durability
Road trips expose your gear to rain, snow, and road debris. Hard-shell boxes generally offer superior weather resistance, but quality soft-sided bags with waterproof features can also perform well in lighter rain. Check for features like sealed zippers, UV-resistant materials, and secure locks to keep your belongings dry and safe over long distances.
Ease of Installation and Access
How quickly and securely a box attaches to your roof rack can differ dramatically. Dual-side opening models provide greater convenience, especially when parking in tight spaces. Consider whether your vehicle has a compatible rack system and if the mounting process is straightforward without needing specialized tools, saving you time and effort at each trip’s start and end.
Security Features
Theft prevention is important when leaving your vehicle unattended. Look for boxes with integrated locks or secure fastening systems. Remember that heavier, lockable hard-shell options typically offer better protection than soft-sided bags, but they may require more effort to open or remove.
Budget and Value
While a lower price may be tempting, it can come at the cost of durability, security, or ease of use. Investing a bit more often results in a box that lasts longer and performs better under harsh conditions. Balance your budget with the features that matter most—like capacity, weatherproofing, and security—to find the best value for your needs.
Frequently Asked Questions
Will a roofcargo box fit on my vehicle’s roof rack?
Most roofcargo boxes are designed to fit standard roof racks, but compatibility depends on your specific vehicle and rack system. Check the dimensions and mounting compatibility listed by the manufacturer, and ensure your roof rack has sufficient weight capacity. If you have a more unusual or custom rack setup, some models offer adaptable mounting options or require additional accessories to fit securely.
How much additional fuel will a roofcargo box typically add to my trip?
The added weight and aerodynamic drag of a roofcargo box can slightly decrease fuel efficiency—often by 10-15%. Larger, heavier boxes tend to have a more noticeable impact, especially at highway speeds. To minimize this, choose a size that meets your needs without excess bulk and ensure the box is mounted as low and as close to the roof as possible to reduce wind resistance.
Are soft-sided roof bags as secure and weatherproof as hard-shell boxes?
Soft-sided roof bags can be waterproof if they feature high-quality materials and sealed zippers, but they generally offer less impact resistance and security than hard-shell options. They are more vulnerable to tearing, theft, and extreme weather conditions. However, they are lighter and easier to store when not in use, making them a good choice for lighter loads or short-term use in fair weather.
How do I prevent my roofcargo box from damaging my vehicle’s roof or rack?
Proper mounting and using protective accessories like anti-slip mats or padding can prevent damage. Always follow manufacturer instructions for installation and avoid over-tightening clamps. Regularly check the mounting system during long trips, and ensure the box is balanced to prevent uneven stress on your roof rack, which can cause scratches or dents over time.
What’s the best way to load and unload a roofcargo box safely?
Use a stable platform or step ladder to reach your roof comfortably. Distribute weight evenly inside the box to avoid imbalance while driving. When unloading, take care to lift with proper posture and avoid overloading on one side. Securing your gear properly inside the box with straps or nets prevents shifting during transit, making loading and unloading safer and easier.
Conclusion
For most road trip travelers, the Rooftop Cargo Box Carrier offers an excellent balance of capacity, security, and durability, making it the best overall choice. Those on a tighter budget or seeking flexibility might prefer the Asinking Car Rooftop Cargo Carrier Bag, which is easier to store and lighter to handle. If you prioritize premium features and maximum security, investing in a higher-end hard-shell like the SportRack Vista XL makes sense. Beginners or occasional travelers should look for models with straightforward installation, while frequent road trippers with larger gear needs should consider models with larger capacities and dual-side access. Carefully match your choice to your vehicle’s rack system, typical load, and trip conditions for the best experience.
