More Details on Our Top Picks
GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
This GarveeTech model stands out for its durable ABS construction and dual-sided access, making it particularly convenient compared with the SportRack Vista XL, which has a rear-opening design. The 12 cubic feet capacity suits most family trips, but the need to verify roof rack compatibility adds a layer of planning that might not suit everyone. Its weather-resistant features outperform many fabric-based options, yet the universal fit relies heavily on vehicle roof rack presence. For those seeking a reliable, weatherproof cargo solution with easy access, this makes a strong contender despite some installation caveats.
Pros:- Durable and weather-resistant ABS construction
- Large 12 cubic feet capacity for versatile storage
- Dual-sided opening for easy access
Cons:- Requires verification of roof rack compatibility
- Limited to vehicles equipped with roof racks
Best for: Families or outdoor enthusiasts needing a durable, weatherproof cargo box with easy side access.
Not ideal for: Owners of vehicles without roof racks or those seeking a lightweight, quick-install option.
- 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
- Warranty:1 year
Our verdict“This cargo box offers reliable weather protection and easy access, ideal for those with compatible roof racks seeking durability.”
GarveeTech Rooftop Cargo Box Carrier, 12 Cubic Feet, Black
Compared with the dual-sided GarveeTech model, this option emphasizes security with included keys and straps, making it ideal for travelers concerned about theft. Its 12 cubic feet of capacity remains suitable for most trips, but the weight may be a concern during installation and removal, especially for those with limited strength or assistance. Its high-quality ABS build provides weather resistance comparable to the dual-sided model, but limited color options mean less customization. This pick makes the most sense for users prioritizing security and weatherproofing over ease of handling.
Pros:- Secure lock system with keys for theft protection
- Weather-resistant ABS construction
- Includes straps for added cargo stability
Cons:- May be heavy to install and remove
- Limited color options
Best for: Travelers who need secure, weather-resistant cargo space that protects valuables during outdoor trips.
Not ideal for: Those who prefer lightweight, easy-to-mount options or who seek a variety of color choices.
- Material:ABS plastic
- Capacity:12 cubic feet (340L)
- Dimensions:54.3 in L x 31.5 in W x 13.4 in H
- Weight Capacity:165 lbs
- Color:Black
Our verdict“Ideal for security-conscious travelers requiring weatherproof cargo protection with added theft deterrents.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This ABS plastic cargo box provides weather resistance and increased capacity suitable for crossbar-equipped vehicles. Compared with the GarveeTech models, it offers a more straightforward, tool-free setup, but its fit is limited to vehicles with cross bars, unlike the universal fit of the soft-sided options. Its 110 lbs weight capacity is adequate for many travel needs, yet the specific vehicle compatibility may restrict some users. If you prioritize simple installation and weather protection, this model offers a reliable choice, but it’s less flexible for different roof rack setups.
Pros:- Durable and weather-resistant ABS construction
- Easy to install without tools
- Secure lock system for safe storage
Cons:- Fits only vehicles with cross bars
- May require additional mounting accessories for some vehicles
Best for: Outdoor travelers with cross bar-equipped vehicles seeking a durable, weatherproof cargo solution that installs without tools.
Not ideal for: Owners of vehicles without cross bars or those needing a more flexible, universal fit.
- Material:ABS plastic
- Capacity:110 lbs
- Dimensions:53 x 34 x 15 inches
- Includes:Cargo box, keys, mounting brackets, hardware
- Color:Black textured finish
Our verdict“A solid choice for cross bar-equipped vehicles prioritizing durability and quick, tool-free installation.”
MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks Option
This flexible PVC cargo bag offers an impressive 20 cubic feet of storage, ideal for those needing maximum space on any vehicle. Compared with hard-shell options like the SportRack Vista XL, it excels in versatility, fitting cars with or without roof racks thanks to its malleable design. While its waterproof PVC makes it highly suitable for outdoor adventures, the softer construction may lack the rigidity some users prefer for stacking or stacking heavy loads. For travelers who value capacity and adaptable mounting, this bag provides ample space but may require additional racks or straps for optimal security.
Pros:- Massive 20 cubic feet capacity
- Waterproof PVC material keeps contents dry
- Fits all cars with or without roof racks
Cons:- May require additional racks for security
- Malleable design might be less stiff for stacking
Best for: Outdoor enthusiasts or large families needing maximum cargo capacity on various vehicle types without the need for rigid shells.
Not ideal for: Those who prefer rigid protection or need to stack multiple hard-shell boxes securely.
- Capacity:20 Cubic Feet
- Dimensions:51.1” x 39” x 17”
- Material:PVC
- Includes:Anti Slip Mat, 6 straps, 2 3M straps
- Fits:All cars with or without roof rack
Our verdict“Best suited for large-scale outdoor trips where maximum cargo space and flexibility outweigh rigid protection.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL offers a generous 18 cubic feet of storage with a rear opening, providing easy access to gear without repositioning the vehicle. Compared to the GarveeTech options, which feature side access, this design is more familiar and simplifies loading and unloading for many users. Its UV-resistant ABS ensures durability against sun exposure, but its size can be a challenge for smaller vehicles. While tool-free mounting makes setup quick, verifying fit with specific rack systems remains necessary. This model is ideal for those prioritizing large capacity and straightforward access, even if it means dealing with a slightly bulkier profile.
Pros:- Large 18 cubic feet capacity
- Durable UV-resistant ABS
- Rear opening for easy access
Cons:- May be bulky for small vehicles
- Requires verification of fit with specific rack systems
Best for: Outdoor adventurers or families needing a large, accessible cargo space that is simple to mount and use.
Not ideal for: Small vehicles or owners seeking a low-profile, less bulky cargo box.
- Capacity:18 cubic feet (510L)
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 in
- Crossbar Spacing:23 5/8 – 29 3/4 in
- Max Weight Capacity:100 pounds
Our verdict“Ideal for those needing ample cargo space with straightforward rear access for frequent gear loading and unloading.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier, 61″ L x 27.6″ W x 13.8″ H, Dual-Side Opening, for SUV, Car, Van, Black
This cargo box stands out for its combination of weatherproof ABS construction and dual-side access, making it ideal for those needing reliable protection and easy loading. Compared to the GarveeHeavy Duty Hard Shell, the TUFFIOM offers a slightly smaller capacity but benefits from a more compact profile and a secure lock system with keys, enhancing security during storage. Its 13.4 cubic feet capacity is sufficient for most family trips but may fall short for large groups. The durable ABS shell ensures protection from rain, snow, and UV rays, while the locking mechanism adds peace of mind. A minor tradeoff is the weight—roughly 24 lbs—potentially making it less user-friendly for some. Overall, this option makes the most sense for SUV owners seeking a weather-resistant, secure cargo solution that’s straightforward to access and install.
Pros:- Waterproof ABS shell offers excellent weather protection
- Dual-side opening provides convenient access from either side
- Secure locking system with keys enhances security
- Suitable for most vehicles with compatible crossbars
Cons:- Protective film on lid requires removal before use
- Weight may be cumbersome for some users
Best for: Families or solo travelers prioritizing weatherproof security and dual-side access
Not ideal for: Users needing maximum capacity or lightweight options, as it’s somewhat heavy and mid-sized
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Material:ABS
- Max Load Capacity:150 lbs
- Locking System:Yes, with keys
- Weight:approximately 24.25 lbs
Our verdict“This cargo box is best for those wanting secure, weatherproof storage with easy dual access on SUVs or larger vehicles.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
Compared with premium options like the Thule Motion 3, the Auto Dynasty offers a generous 12.7 cubic feet of impact-resistant storage at a more accessible price point. Its wide opening facilitates easier loading and unloading, especially on longer road trips. Constructed from weather-resistant ABS, it withstands UV rays and impacts well, making it suitable for outdoor adventures. The lock system enhances security, though the universal fit may not suit all vehicle crossbars, requiring careful measurement beforehand. The impact-resistant ABS and simplified installation make this model appealing for budget-conscious buyers who need a spacious, durable box without complex features. However, its fit limitations and slightly narrower opening (13.5 inches) compared to larger models like the Garvee Heavy Duty mean it’s less ideal for large bulky items.
Pros:- Spacious 12.7 cubic feet capacity for outdoor gear
- Weather-resistant and impact-protected for all conditions
- Secure lock system enhances safety
- Easy to install with heavy-duty brackets
Cons:- Universal fit may not match all vehicles’ crossbars
- Limited maximum opening width (13.5 inches)
Best for: Outdoor enthusiasts seeking a high-capacity, impact-resistant cargo box on a budget
Not ideal for: Owners of vehicles with non-standard crossbar sizes or those needing maximum opening width
- Capacity:12.7 Cubic Feet
- Dimensions:55″ L x 34.5″ W x 14″ H
- Material:UV-protected, weather-resistant ABS
- Opening Width:13.5 inches
- Weight Limit:110 lbs
Our verdict“This model provides a solid, impact-resistant storage solution suitable for outdoor adventurers on a budget, with some fit considerations.”
Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier – 69″L x 33″W x 11″H, Waterproof, Lockable, 17 Cu Ft Capacity
This carrier stands out for its large capacity—17 cubic feet—making it ideal for extensive trips or camping gear. Its rugged ABS plastic with UV-resistant coating ensures durability in harsh weather, rivaling the Rooftop Cargo Carrier, 18 Cu Ft, but with a slightly more compact height for easier handling. Its lockable, waterproof design offers peace of mind, whether parked or in transit. The tool-free installation is a plus, but the size and weight—over 50 lbs—may challenge users during setup, especially without assistance. The larger capacity and rugged build make it perfect for heavy-duty use, yet it may be overkill for those with minimal storage needs or limited roof rack compatibility. This model is best suited for serious outdoor enthusiasts who need maximum capacity and durability.
Pros:- Large 17 cu ft capacity for extensive gear
- Waterproof and UV-resistant for durability
- Easy to install without tools
- Lockable for added security
Cons:- Heavy weight may complicate handling
- Requires compatible roof racks, limiting universality
Best for: Adventurers and families needing a rugged, high-capacity carrier for frequent use
Not ideal for: Occasional travelers or those with smaller roof rack dimensions, due to size and weight
- Dimensions:69″L x 33″W x 11″H
- Capacity:17 Cu Ft
- Material:ABS plastic with UV-resistant coating
- Weight Capacity:165 lbs
- Installation:Tool-free, hardware included
Our verdict“This heavy-duty carrier is perfect for those who prioritize maximum capacity and rugged weatherproof protection over ease of handling.”
Goplus Rooftop Cargo Carrier Hard Shell, 14 Cubic Feet Waterproof Car Roof Cargo Carrier with Dual Side Opening, Security Key, 165 lbs Capacity, Fits 17” to 22.8” Wide Crossbar Racks
Compared with the Auto Dynasty, the Goplus offers a slightly larger 14 cubic feet of waterproof storage and a more versatile fit for crossbars between 17” and 22.8”. Its dual-side opening makes loading convenient from either side, and the double-lock design adds security. Made from durable ABS and PC materials, it’s designed for rough weather conditions and frequent use. Installation is quick with the supplied anchors, but it’s important to ensure your vehicle’s rack dimensions match the specified range. While it doesn’t open both sides simultaneously, its aerodynamic shape minimizes wind noise at high speeds. This model makes sense for users seeking a balance of size, security, and ease of installation in a versatile, waterproof package.
Pros:- 13 cubic feet of waterproof, durable storage
- Dual-side opening for convenience
- Double-lock security system
- Fits a wide range of rack widths
Cons:- Requires compatible rack dimensions
- Cannot open both sides simultaneously
Best for: Road trip enthusiasts needing a reliable, waterproof cargo box with flexible rack compatibility
Not ideal for: Vehicles with racks outside the specified width range or those seeking an open-side design for large bulky items
- Capacity:14 Cubic Feet
- Material:ABS and PC
- Weight Capacity:165 lbs
- Compatible Rack Width:17” to 22.8”
- Locking Mechanism:Double-lock
Our verdict“This cargo carrier offers a versatile, secure waterproof solution for travelers with compatible roof racks needing reliable outdoor storage.”
Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA
This 18-cubic-foot carrier excels for its large capacity and sturdy construction, making it a prime choice for those with extensive gear. Its heavy-duty HDPE plastic shell provides weatherproofing and durability, comparable to the GarveeHeavy Duty but with a more substantial size. Made in the USA, it offers added assurance of quality. The dual side openings and lock system enhance security, while its design aims for straightforward installation. However, its size—measuring 57″ L x 38.5″ W x 17.75″ H—means it may impact vehicle aerodynamics and requires a robust roof rack. While perfect for serious hauling, it’s less suitable for vehicles with limited rack capacity or those seeking a lightweight option for occasional use. This carrier is best for users who need maximum volume and rugged construction for frequent, heavy-duty trips.
Pros:- Huge 18 cubic feet capacity for extensive gear
- Weatherproof, heavy-duty HDPE construction
- Dual side openings for easy access
- Made in the USA for quality assurance
Cons:- Large size may affect vehicle aerodynamics
- Requires a strong roof rack due to weight and size
Best for: Heavy-duty outdoor users and large families needing maximum volume and American-made quality
Not ideal for: Compact vehicles or infrequent travelers who want a lightweight, smaller option due to its size and weight
- Capacity:18 cubic feet
- Material:HDPE plastic
- Dimensions:57 L x 38.5 W x 17.75 H inches
- Made in:USA
Our verdict“This heavy-duty, American-made carrier is ideal for those needing maximum volume and rugged durability for frequent outdoor use.”
Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier, Lockable & Weatherproof
This cargo box stands out for its straightforward design and reliable weatherproofing, making it a solid choice for those who want extra space without complicating their roof rack setup. Compared to the Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier, it offers a slightly smaller capacity but is easier to install on most crossbars without drilling, which broadens compatibility. Its UV-protected ABS shell resists the elements well, yet it is limited to 125 lbs, so very heavy loads are a concern. The strut-assisted lid simplifies loading, especially on longer trips, but the lack of detailed vehicle compatibility info could cause issues with some roof rack systems. This pick makes the most sense for casual travelers who need a weatherproof, lockable box with easy installation, but not for heavy-duty hauling.
Pros:- Expands cargo capacity without sacrificing interior space
- Weatherproof and lockable for security
- Easy to install on most roof racks without drilling
Cons:- Limited to 125 lbs weight capacity, restricting heavier loads
- Requires compatible crossbar system, which may limit vehicle options
Best for: Families or outdoor enthusiasts seeking dependable weatherproof storage that fits most crossbar systems without hassle.
Not ideal for: Users regularly hauling loads over 125 lbs or those with highly specialized roof rack setups that require custom fitment.
- Capacity:14.5 cu ft
- Interior Dimensions:65″ L x 32″ W x 13″ H
- Weight Capacity:125 lbs
- Material:UV-protected ABS
- Installation:Universal crossbar fit, no drilling required
- Made in:USA
Our verdict“This cargo box offers a reliable, easy-to-install option for those needing weatherproof storage without heavy weight demands.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 excels for travelers who prioritize aerodynamic efficiency and premium accessories. Its wing-shaped profile reduces drag, which can lead to noticeable fuel savings over long trips, unlike the bulkier options like the WORKPRO Waterproof Car Roof Bag. Mounting is straightforward thanks to the PowerClick system, providing a secure fit that’s ideal for frequent use. The integrated SlideLock system with an indicator enhances security, and included accessories like interior lighting and a protective liner increase convenience. However, the lack of specific capacity details might be a downside for those needing precise size estimates, and its higher price point makes it less attractive for budget-conscious buyers. This makes it well-suited for frequent travelers who want a combination of style, security, and ease of use, but less so for those on a tight budget or with limited roof space.
Pros:- Aerodynamic profile reduces drag and improves fuel efficiency
- Easy to mount securely with the PowerClick system
- Includes useful accessories like interior lighting and a storage cover
Cons:- Lack of specific capacity details may hinder planning
- Premium price may be a barrier for some buyers
Best for: Travelers who value aerodynamic design, premium features, and frequent use with an easy mounting system.
Not ideal for: Budget shoppers or those requiring precise capacity measurements for planning larger loads.
- Design:Wing-shaped profile with forward-leaning nose
- Features:PowerClick quick-mount, SlideLock system, integrated torque indicator
- Accessories:Interior box light, protective liner, storage cover
Our verdict“This rooftop box is ideal for frequent travelers seeking style, efficiency, and premium features in a durable package.”
WORKPRO Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Car Roof Bag
The WORKPRO Rooftop Cargo Carrier Bag offers the largest capacity among these options, making it perfect for outdoor trips and extended travel. Its 21 cubic feet of waterproof space contrasts with the rigid Rough Country box, providing flexibility for irregularly shaped loads. Its durable 840D PVC material and reinforced straps ensure weather resistance and stability, but it’s not a hard-shell carrier, which means it offers less protection against impacts or theft. Installation is straightforward with multiple adjustable straps and safety hooks, yet it requires careful handling to avoid tears and may not be fully waterproof under extreme conditions. This bag suits those needing maximum volume and weather resistance without the bulk of a hard shell, but it isn’t the best choice for very heavy or fragile cargo.
Pros:- Large 21 cubic feet capacity for maximum storage
- Waterproof and weather-resistant material
- Easy to install with multiple straps and safety features
Cons:- Less durable in extreme impact situations
- Potential for tearing if not handled carefully
Best for: Adventurers or campers needing large, flexible, waterproof storage that’s easy to install and remove.
Not ideal for: Those requiring a rigid, highly durable shell for extreme weather or heavy loads, or for theft security.
- Capacity:21 cubic feet
- Dimensions:52″x40″x17″
- Material:840D PVC
- Number of straps:10 reinforced adjustable straps
- Includes:Safety hooks, storage bag, user manual
Our verdict“This waterproof bag is an excellent choice for those who prioritize maximum volume and weather resistance over rigid protection.”
How We Picked
The products in this roundup were evaluated based on several key criteria: build quality, weatherproofing, ease of installation, security features, capacity, and value for money. I prioritized models with high user ratings and trusted brand reputations to ensure reliability. The ranking reflects a balance between performance and affordability, with premium options placed higher for those seeking durability, and budget choices included for cost-conscious buyers. Each product was compared to others in its category to identify standout features, limitations, and how well it suits different types of travelers and vehicle setups.Factors to Consider When Choosing Rated Rooftop Cargo Boxes
Choosing the right rooftop cargo box involves more than just capacity. It’s important to consider compatibility with your vehicle, security features, and how easy it is to access your belongings while on the road. Material quality and weatherproofing are vital for protecting your gear in various climates. Additionally, think about installation complexity and whether the box’s weight affects your vehicle’s handling. Balancing these factors with your budget will help you select a cargo box that meets your travel needs without unnecessary compromises.Capacity and Size
The capacity of a cargo box determines how much gear you can carry, but larger models also tend to be heavier and more aerodynamic. Measure your vehicle’s crossbar spread and height restrictions to avoid buying a box that won’t fit. Remember, a slightly smaller box that fits well can be easier to install and handle than a larger, unwieldy one. Think about your typical trip length and gear volume to choose a size that balances space with manageability.Weatherproofing and Durability
A rooftop cargo box is exposed to the elements, so investing in a waterproof, UV-resistant shell is essential for protecting your belongings. Hard-shell models generally outperform soft bags in heavy rain or snow, offering better security and weather resistance. However, they often cost more and can be heavier, making installation more challenging. Consider the climate you’ll be traveling in and whether extra weatherproofing features justify the price premium.Security Features
Locking mechanisms are a key aspect of security — especially if you plan to leave your vehicle unattended. Look for models with integrated locks that are easy to operate but resistant to tampering. Soft-sided cargo carriers typically lack locks, making them less secure but lighter and more flexible. Weigh the importance of security against convenience and cost, especially if you’re traveling in high-theft areas.Ease of Installation and Access
A cargo box that’s easy to mount and remove saves time and effort, particularly if you frequently switch vehicles or need quick access. Dual-side opening models offer the advantage of accessing your gear from either side of the vehicle, but may add weight and complexity. Consider whether your vehicle’s roof rails are compatible and if the installation process suits your skills or available tools.Cost and Value
Prices vary widely based on features, size, and brand reputation. While premium models offer advanced security, superior materials, and aerodynamic designs, budget options can still provide waterproofing and decent capacity. Determine your budget first, then choose a model that maximizes features for that price point. Remember, investing in a slightly higher-priced model can pay off through better durability and security over time.Frequently Asked Questions
Will a larger cargo box affect my vehicle’s fuel efficiency?
Yes, a larger and heavier cargo box can increase wind resistance and overall weight, which may reduce your vehicle’s fuel economy. The impact depends on the size and shape of the box, as well as your driving conditions. Aerodynamic designs help mitigate this effect, but expect some decrease in efficiency if you opt for a very large or bulky model. It’s worth balancing your capacity needs with potential fuel savings.Are soft-sided cargo carriers as durable as hard-shell options?
Soft-sided carriers tend to be less durable and weather-resistant than hard-shell models, especially in heavy rain or snow. They are more flexible and easier to store when not in use, but they usually lack locking mechanisms and may be more vulnerable to tearing or UV damage over time. If security and weather protection are priorities, a hard-shell cargo box generally offers better long-term performance.Can I install a rooftop cargo box on any vehicle?
Most rooftop cargo boxes are designed to fit a range of vehicles with crossbars, but compatibility depends on your roof rack’s size, shape, and weight capacity. Always measure your vehicle’s crossbar spread and verify the maximum weight your roof can support. Some models include adjustable mounting systems, making them more versatile, but it’s crucial to confirm fit before purchasing to avoid installation issues.How important is security when choosing a rooftop cargo box?
Security should be a top consideration if you plan to leave your vehicle unattended, especially in public or high-theft areas. Look for models with integrated locks that are resistant to tampering. While soft carriers usually lack security features, hard-shell boxes often include locking mechanisms that can help protect your gear. Weigh the value of security against convenience and budget constraints in your decision.What maintenance does a rooftop cargo box require?
Regular maintenance includes cleaning the exterior to remove dirt and debris, inspecting the locking mechanisms for corrosion, and checking mounting hardware for tightness. Hard-shell models may need occasional lubrication on hinges or locks. Store soft bags in a dry, cool place when not in use to prolong their lifespan. Proper maintenance ensures your cargo box remains weatherproof and secure over many trips.Conclusion
For most buyers, the Thule Motion 3 offers the best balance of durability, ease of use, and security, making it ideal as the overall top pick. Budget-conscious travelers will appreciate the WORKPRO Rooftop Cargo Carrier Bag for its waterproofing and flexibility. Those seeking premium features and maximum security should consider the GarveeTech Dual-Side Opening Cargo Box or the Goplus Hard Shell Carrier. If you’re new to rooftop cargo solutions, a lightweight, easy-to-install soft bag might be best. For specific needs like high-capacity or weather-resistant options, focus on models that emphasize those features, ensuring your gear stays protected no matter the trip.Fall yard work Picks
