More Details on Our Top Picks
GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Roof Luggage Storage
The GarveeTech rooftop cargo box stands out for its durable ABS construction, offering excellent weather resistance, which makes it a reliable choice for all-season trips. Its 12 cubic feet of storage strikes a balance between capacity and ease of handling, while dual-sided opening enhances convenience when accessing your gear. Compared to the Thule Motion 3, it provides comparable capacity but at a lower price point, though it requires verification to ensure compatibility with specific roof racks. The security features, including locks and straps, add peace of mind, but it’s limited to vehicles with suitable roof racks. This model is an ideal fit for families or travelers seeking a robust, weatherproof cargo solution without the premium price.
Pros:- Durable, weather-resistant ABS construction
- Large 12 cubic feet capacity
- Dual-sided opening for easy access
- Includes security locks and straps
Cons:- Requires roof rack compatibility verification
- Limited to vehicles with roof racks
Best for: Families or long-distance travelers needing large, weather-resistant storage that’s easy to secure and access.
Not ideal for: Owners of small or roof-rack-free vehicles, as compatibility and installation could be challenging.
- Material:ABS
- Capacity:12 cubic feet (340L)

Our verdict“Best suited for those needing a tough, weatherproof cargo box with ample space for family adventures.”
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Ft
The Thule Pulse 2 M offers a generous 14 cubic feet of storage, making it well-suited for weekend trips or daily commuting. Its tool-free installation system with a torque indicator simplifies setup, unlike some bulkier options that require more effort. Made from weather-resistant ASA-ABS plastic, it withstands harsh conditions better than lower-grade materials. While it shares capacity with the Thule 614 Pulse, the Pulse 2 M’s sleek design and easy mounting make it more appealing for quick trips. However, its size may be a challenge for smaller vehicles, and it mandates a roof rack for installation. This pick is best for users prioritizing quick setup and reliable weatherproofing in a mid-sized cargo box.
Pros:- Large 14 cubic feet capacity
- Easy, tool-free mounting with torque indicator
- Weather-resistant ASA-ABS plastic
- Dual-side access
Cons:- May be bulky for small vehicles
- Requires roof rack for installation
Best for: Commuters or weekend travelers with larger vehicles seeking quick, tool-free setup and dependable durability.
Not ideal for: Drivers of compact cars or those with tight roof space, due to its size and bulk.
- Capacity:14 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
Our verdict“Ideal for users who want a large, durable cargo box that installs quickly without tools.”
Thule 614 Pulse Cargo Box, Medium, Black
The Thule 614 Pulse is tailored for winter sports enthusiasts, offering 14 cubic feet of space and a rugged build. Its quick-mount system simplifies installation compared to more cumbersome models, and the passenger-side opening provides easy access without reaching over the vehicle. The central locking system enhances security, a feature that is less common in similar-sized boxes like the SportRack Vista XL. However, at 34 lbs, it can be cumbersome to handle alone, especially when mounting on higher vehicles. Its specific size and snowboard capacity—up to 155 cm—make it less versatile for general cargo. This is best for snowboarding families or those needing secure, quick access to gear in cold climates.
Pros:- 14 cubic feet storage capacity
- Quick, secure mounting system
- Passenger-side opening for easy access
- Central locking enhances security
Cons:- Heavy at 34 lbs, handling alone is difficult
- Limited to snowboards up to 155 cm in length
Best for: Snowboarders or winter sports fans needing secure, easy-to-access outdoor gear storage.
Not ideal for: Those seeking a multi-purpose cargo box for diverse gear types or larger capacities.
- External dimensions:67 x 35 x 16 inches
- Internal dimensions:61 x 33 x 14 inches
- Load capacity:110 lbs
- Product weight:34 lbs
- Fits:3-5 snowboards (max length: 155 cm)
Our verdict“Best for winter sports enthusiasts prioritizing security and quick access for snow gear.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 combines an aerodynamic, wing-shaped profile with advanced features like interior lighting and a protective liner, making it a premium choice. Its design reduces drag, potentially saving fuel over less streamlined boxes like the SportRack Vista XL. The PowerClick mounting system with torque indicator offers a secure, one-handed setup that’s quicker and more reliable than traditional clamps. While specific capacity details aren’t listed here, it’s generally comparable to other high-end boxes in size and volume. Its high price point isn’t suited for casual users but appeals to those who value efficiency, convenience, and extra accessories. This model is ideal for frequent travelers who want a stylish, feature-rich cargo solution.
Pros:- Aerodynamic design reduces drag and improves fuel efficiency
- Easy one-handed opening
- Secure PowerClick mounting system with torque indicator
- Additional accessories like interior lighting
Cons:- Lacks explicit capacity details here, potentially limiting for very large loads
- Higher price point may be a barrier for some buyers
Best for: Travelers seeking a sleek, aerodynamic box with advanced mounting and added accessories for frequent use.
Not ideal for: Budget-conscious buyers or those with small vehicles, due to its higher cost and size.
- Design:Wing-shaped profile
- Mounting System:PowerClick quick-mount
- Locking Mechanism:SlideLock system
- Accessories:Interior light, protective liner
Our verdict“Perfect for frequent travelers who prioritize efficiency, premium features, and ease of use over cost.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier
The TUFFIOM 13.4 cu.ft. cargo box offers a solid capacity for its price point, with waterproof ABS construction ensuring your gear stays dry in challenging conditions. Its dual-side opening makes access convenient from either side, a feature that enhances usability compared to single-opening models like the Thule 614 Pulse. With a secure locking system and a max load capacity of 150 lbs, it caters well to travelers looking for affordability without sacrificing security. However, installation can be tricky if measurements aren’t precise, and it’s limited to vehicles with compatible crossbar dimensions—so some users might face fit issues. This makes it a good choice for budget-conscious families or casual users who want reliable waterproof protection without premium extras.
Pros:- Affordable price point
- Waterproof ABS shell for all-weather protection
- Dual-side opening for easy access
- Locks with keys for security
Cons:- Installation can require precise measurements
- Limited compatibility with certain roof rack sizes
Best for: Budget-conscious families or casual travelers needing waterproof, secure storage with straightforward installation.
Not ideal for: Owners of small or unconventional roof racks, or those seeking high-end features and lightweight design.
- 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
- Compatibility:Most vehicles with crossbars, max width 2.36″
Our verdict“Ideal for budget-minded users seeking waterproof, secure cargo space for occasional trips.”
GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
The GarveeTech rooftop cargo box stands out for its durable ABS construction and dual-sided opening, making access effortless from either side—ideal for busy families or frequent travelers. Compared to the SportRack Vista XL, which offers a larger capacity but less weather protection, GarveeTech provides a balanced mix of durability and convenience. Its waterproof and UV-resistant features ensure luggage stays dry and protected in all conditions, though it requires verification of roof rack compatibility, which might limit installation options. This model is perfect for those who prioritize weatherproofing and ease of access, but less so if your vehicle lacks compatible roof racks.
Pros:- Durable, weather-resistant ABS construction
- Provides ample 12 cubic feet of storage
- Dual-sided opening for increased convenience
- Includes 2 keys and 2 straps for security
Cons:- Requires verification of roof rack compatibility
- Limited to vehicles equipped with roof racks
Best for: Families or individuals who need durable, weather-resistant storage with flexible access from either side.
Not ideal for: Drivers without compatible roof racks or those seeking a lightweight, budget-friendly 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
- Features:Waterproof, UV-resistant, Dual-sided opening, Includes 2 keys and 2 straps
Our verdict“This pick is best for users wanting a weatherproof, easy-access cargo solution with reliable durability.”
DNA MOTORING Rooftop Cargo Box Carrier Lockable Heavy Duty Car Top Storage Case, 11 Cubic Feet, 53″ L x 34″ W x 15″ H, Textured Black
The DNA MOTORING cargo box offers a robust, impact-resistant ABS shell with a lockable lid, making it well-suited for travelers concerned about security. Unlike the SportRack Vista XL, which provides more capacity but less security, this model emphasizes locking features to safeguard valuables. Its 11 cubic feet of space is sufficient for many trips, but the need for cross bars and the absence of included hardware could complicate setup. This choice makes sense for users prioritizing security and impact resistance, yet those seeking maximum capacity or easy installation might opt for larger or simpler models.
Pros:- Secure lockable lid with key
- Impact-resistant ABS construction
- Compact 11 cubic feet capacity
- Textured black finish for durability
Cons:- Requires cross bars for installation
- No included mounting hardware, complicating setup
Best for: Travelers who value security and impact resistance over sheer volume, especially with vehicles equipped with cross bars.
Not ideal for: Owners of vehicles without cross bars or those who want a larger capacity without additional mounting hardware.
- Capacity:11 Cubic Feet
- Max Load Capacity:110 lbs
- Dimensions:53″ L x 34″ W x 15″ H
- Material:Impact-resistant ABS
- Finish:Textured Black
Our verdict“Ideal for users needing a durable, secure roof box in a manageable size for frequent, security-conscious trips.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
The Auto Dynasty cargo carrier is designed for quick, tool-free installation, fitting cross bars up to 13 inches wide. Compared with the SportRack Vista XL’s rear-opening design, this model offers a spacious 11 cubic feet capacity with a focus on impact protection and weather resistance. Its UV-protected ABS shell and secure lock system make it suitable for outdoor adventures, yet the universal fit might require buyers to double-check cross bar dimensions before purchase. This pick is best for users who want a straightforward, impact-protected cargo box that’s compatible with a wide range of vehicles, but less ideal for those needing a larger capacity or specialized mounting.
Pros:- Easy, tool-free installation
- Impact-protected, weather-resistant ABS shell
- Secure lock system with keys
- Fits cross bars up to 13 inches wide
Cons:- Limited to cross bars up to 13 inches wide

Best for: Drivers seeking a universal-fit, impact-resistant roof box with quick, tool-free setup.
Not ideal for: Owners with cross bars wider than 13 inches or those with very specific vehicle dimensions requiring custom solutions.
- Dimensions:53″ L x 34″ W x 15″ H
- Capacity:11 Cubic Feet
- Weight Limit:110 lbs
- Material:UV-protected, weather-resistant ABS
- Includes:Security lock keys, heavy-duty mounting brackets
Our verdict“Best for users who want a straightforward, impact-protected cargo box that’s quick to install and fits most cross bars within size limits.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL provides a massive 18 cubic feet of storage, making it an excellent choice for large families or long trips. Its UV-resistant ABS shell and tool-free mounting make installation straightforward, but the 100-pound weight limit can be restrictive for heavier, bulkier loads. Compared to the GarveeTech, which offers dual-side access, Vista XL’s rear opening simplifies loading, especially from a single side, though it may be less convenient for quick access from both sides. Its size and ease of use make it a popular option, but you should be mindful of its weight capacity and dimension fit for your vehicle.
Pros:- Massive 18 cubic feet capacity
- Easy rear access for loading
- UV-resistant ABS exterior
- Tool-free mounting hardware
Cons:- Limited to 100 pounds weight capacity
- Dimensions may not fit all vehicles
Best for: Large families or groups needing maximum cargo volume with simple rear access and easy mounting.
Not ideal for: Vehicles with limited roof space or owners who prioritize security features over sheer capacity.
- Capacity:18 cubic feet
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Max Weight Capacity:100 pounds
- Min-Max Crossbars Spacing:23 5/8 – 29 3/4 inches
Our verdict“Perfect for those needing maximum cargo space and straightforward rear access, especially on larger vehicles.”
12 Cubic Rooftop Cargo Box Carrier, Dual-Side Opening Hard-Shell Vehicle Roof Mount Travel Luggage Storage, 135Lbs Capacity, Black
The 12 Cubic Rooftop Cargo Box Carrier emphasizes aerodynamics and noise reduction, making it ideal for long drives. Its dual-sided opening and waterproof ABS shell ensure easy access and reliable protection, akin to the GarveeTech but with a focus on reducing wind resistance. With a 135 lbs capacity, it balances capacity with a design optimized for efficiency at high speeds. Compared with the DNA MOTORING option, which offers slightly less capacity but a more compact fit, this model prioritizes fuel efficiency and low noise. It’s best suited for those who want a sleek, aerodynamic cargo solution for extended trips but may not be suitable for vehicles with incompatible roof designs or those needing maximum volume.
Pros:- Durable, waterproof ABS construction
- Aerodynamic, noise-reducing design
- Generous 12 cubic feet capacity
- Dual-sided opening for ease of access
Cons:- Requires verification of roof rack compatibility
- May increase wind noise at high speeds
Best for: Long-distance travelers who prioritize aerodynamics and low wind noise without sacrificing significant cargo space.
Not ideal for: Owners seeking the highest capacity or those with roof racks incompatible with its dimensions.
- Material:ABS
- Capacity:12 cubic feet (340L)
- Dimensions:54.3″L x 31.5″W x 13.4″H
- Weight Capacity:135 lbs
- Opening:Dual-sided
Our verdict“Ideal for road trippers who want a sleek, aerodynamic cargo solution for fuel efficiency and quiet operation.”
INNO Roof Box 320 Matte Black 9 cu ft Cargo Box
The INNO Roof Box 320 stands out for its practical square design and easy installation, especially thanks to the Memory Mount System that fits both Aero and Square bars—making it a flexible choice for many vehicles. Its dual-side opening offers convenient access from either side, a feature that some competitors like the Thule Pulse 2 L lack. While its rugged matte black finish enhances durability and hides scratches well, the overall design can feel bulky on smaller cars, which might impact aerodynamics or aesthetics. Compared to the Thule Pulse 2 L, it’s slightly less aerodynamic but offers a more straightforward installation process for those with different roof rack types. The limited lifetime warranty could be a concern for buyers seeking long-term protection against damage, but overall, this model provides a solid balance of durability, ease of use, and compatibility.
Pros:- Easy to install with the Memory Mount System
- Dual-side opening for convenient access
- Rugged matte black finish enhances durability
Cons:- Limited lifetime warranty may not cover all damages
- Design may be bulky for some vehicles
Best for: Budget-conscious families wanting reliable, easy-to-install storage for moderate trips
Not ideal for: Small cars or sporty vehicles where low-profile, sleek designs are preferred
- Capacity:9 cu ft
- Finish:Matte Black
- Design:Square
- Opening:Dual-side
- Lock System:Safety key lock
- Compatibility:Aero & Square bars
Our verdict“This cargo box makes a smart choice for users needing a versatile, durable option that fits different roof rack styles without a high price tag.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft
The Thule Pulse 2 L offers a generous 16 cubic feet of storage, making it ideal for larger families or outdoor enthusiasts with bulky gear like skis or snowboards. Its tool-free installation system with a torque indicator simplifies setup, providing peace of mind during mounting—an advantage over some simpler models like the INNO Roof Box 320. The weather-resistant ASA-ABS plastic construction ensures your gear stays dry even during heavy rain, a feature that makes it stand out for durability in harsh conditions. However, its size can be a drawback for smaller or compact vehicles, where it may look disproportionate or create additional wind resistance. The 75 kg (165 lbs) load limit is sufficient for most gear, but heavier loads could compromise stability. Compared with smaller boxes, the Pulse 2 L prioritizes capacity and weatherproofing, but buyers should verify vehicle fit first.
Pros:- Easy to install with a tool-free system and torque indicator
- Provides ample space for skis, snowboards, and luggage
- Weather-resistant and durable construction
Cons:- May be bulky for smaller vehicles
- Limited to 75 kg load capacity
Best for: Families or outdoor lovers needing maximum storage space for long trips or snowy gear
Not ideal for: Compact cars or vehicles with limited roof space where bulkiness could impact driving dynamics
- Capacity:16 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:450 liters of cargo space
Our verdict“This cargo box suits those who prioritize large capacity and weatherproofing, accepting some vehicle size limitations.”

Factors to Consider When Choosing Roof Cargo Boxes
Choosing the right roof cargo box involves more than just capacity. Several factors influence how well a box will serve your specific needs, from vehicle compatibility to ease of use. Considering these factors helps avoid common pitfalls like overloading or selecting a model that’s difficult to access. Here are the key aspects to evaluate before making your decision.Capacity and Size
Capacity determines how much gear you can carry, but larger boxes are typically heavier and may impact your vehicle’s aerodynamics. It’s important to match the size to your vehicle’s roof dimensions and weight limits. Overloading can compromise safety and fuel efficiency, so always check your car’s roof load capacity before choosing a larger model. Remember that bigger isn’t always better if it causes handling issues or doesn’t fit your vehicle properly.
Ease of Installation and Access
Look for models with straightforward mounting systems and dual-side opening features if you frequently access your cargo. Easier installation minimizes hassle, especially if you switch vehicles often. Dual-side access is a significant convenience for loading and unloading, particularly when your vehicle is parked close to obstacles or other cars. Avoid overly complex mounting systems that require special tools or extensive effort, as they may discourage regular use.
Aerodynamics and Fuel Efficiency
Box shape and design significantly influence fuel economy. Aerodynamic models with sleek contours tend to cause less drag, saving fuel over long trips. Conversely, bulky or boxy designs, while offering more capacity, may increase wind resistance and reduce efficiency. If you frequently travel long distances, prioritizing aerodynamic shapes can lead to noticeable savings at the pump. Also, consider the profile height to prevent interference with garage doors or low-clearance areas.
Build Quality and Weather Resistance
Durability is vital for protecting your gear in various weather conditions. Look for hard-shell models made from impact-resistant plastics or composites with weatherproof seals. Quality construction prevents water leaks and damage from UV exposure or harsh elements. Cheaper options may crack or warp over time, especially when exposed to sun and snow. Investing in a well-made box can extend its lifespan and ensure your gear stays dry and secure.
Value and Price
Balancing price with features is key. Budget models can be sufficient for occasional use or short trips, but they often lack advanced features like better aerodynamics or dual-side access. Premium brands offer enhanced durability, ease of use, and better aesthetics, which may justify their higher cost if you travel frequently or need reliable performance. Consider how often you’ll use the box and what features are worth paying extra for to avoid overspending on unnecessary extras or underbuying a low-quality model.
Frequently Asked Questions
Can I install a roof cargo box on any vehicle?
Most roof cargo boxes are designed to be compatible with a wide range of vehicles, but it’s essential to check your vehicle’s roof load limit and whether it has factory-installed roof rails or crossbars. Some models come with universal mounting systems suitable for various setups, while others require specific roof rack types. Ensuring your roof can support the weight of the cargo box and its contents is crucial for safety and performance.
How do I know what size cargo box I need?
The size you need depends on the amount and type of gear you plan to carry. Measure your largest items and estimate how many suitcases or bags you’ll load. Keep in mind that larger boxes add weight and can impact fuel efficiency. If you often travel with bulky equipment like skis or camping gear, opting for a bigger capacity makes sense. For occasional trips, a smaller, more aerodynamic model might be sufficient and easier to handle.
Are roof cargo boxes waterproof?
Most hard-shell roof cargo boxes are designed to be weatherproof, with sealed edges and durable materials that resist water ingress. However, the level of waterproofing can vary, especially with cheaper models. Always check for water-resistant seals and reviews that mention water tightness, and consider models with drain plugs or extra sealing features if you plan to carry items sensitive to moisture.
Will a roof cargo box affect my vehicle’s fuel economy?
Yes, adding a roof cargo box can increase aerodynamic drag, which in turn can reduce fuel efficiency, especially on long trips. The impact varies based on the box’s shape, size, and how well it integrates with your vehicle’s design. Opting for a streamlined, aerodynamic model can help mitigate this effect. Also, removing the box when not in use can prevent unnecessary drag and save fuel.
How much weight can a typical roof cargo box support?
Most roof cargo boxes are built to handle between 75 and 165 pounds, but this depends on the model and your vehicle’s roof load capacity. Always verify both the cargo box’s weight limit and your vehicle’s roof load rating before loading heavy items. Overloading can compromise safety, damage your vehicle’s roof, or cause the box to detach. Distributing weight evenly inside the box helps maintain stability during travel.
Conclusion
For those seeking the best overall balance of capacity, durability, and ease of use, the Thule Pulse 2 M is a clear choice. Budget shoppers aiming for reliable storage without breaking the bank will find the GarveeTech Rooftop Cargo Box appealing. If you prioritize premium build quality and aerodynamic design, the Thule Motion 3 or INNO Roof Box 320 make excellent options. Beginners or occasional travelers should consider smaller or simpler models, while frequent or long-distance travelers should invest in high-capacity, weather-resistant options to ensure durability and safety.
