More Details on Our Top Picks
Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier, 17 Cu Ft Waterproof Lockable Storage Box
This Garvee cargo box stands out for its substantial 17 cu ft capacity combined with rugged durability. Unlike the smaller INNO WEDGE660, it offers more space for larger gear, making it ideal for family trips or extended adventures. Its tool-free installation and lockable dual-sided access simplify loading and security, especially compared to the simpler design of the B0D1Y7CHDN option. However, the 165 lb weight capacity can limit heavier loads, and the absence of a manufacturer warranty is a potential concern. This pick makes the most sense for those needing a flexible, weatherproof cargo solution that fits a variety of roof bar types and vehicles.
Pros:- Tool-free installation with included hardware and instructions
- Lockable dual-sided access for easy loading and added security
- Waterproof, UV-resistant construction for all-weather durability
- Compatible with SUVs, trucks, and vans with various roof bar types
Cons:- No manufacturer warranty available
- 165 lb weight capacity may restrict heavier loads
Best for: Families or outdoor enthusiasts requiring high capacity and weatherproof protection on a variety of vehicle types
Not ideal for: Light travelers with minimal cargo needs or those seeking a budget-friendly option with warranty coverage
- Dimensions:69″L x 33″W x 11″H
- Capacity:17 cu ft
- Weight Capacity:165 lbs
- Material:ABS plastic, UV-resistant black coating
- Installation:Tool-free
- Access:Dual-sided opening
Our verdict“Ideal for users who prioritize large capacity, weather resistance, and versatile vehicle compatibility without fussing over installation complexity.”
Hard Shell Roof Top Cargo Carrier – Waterproof Travel Luggage Box
This cargo box offers straightforward, tool-free installation on vehicles equipped with cross bars, making it a top choice for those seeking quick setup and reliable weatherproof protection. Compared with the Garvee, it’s smaller at 53 x 34 x 15 inches and supports a lower load capacity of 110 lbs, which may not suit heavier or larger gear. Its durable ABS plastic and secure key lock provide peace of mind, but it’s limited to vehicles with cross bars only, excluding many SUVs or vans with different roof rack styles. This model makes sense for casual travelers or those with smaller cargo needs who value simplicity and security.
Pros:- Durable waterproof ABS construction protects contents
- Quick, tool-free installation on cross bars
- Secure key lock enhances theft protection
- Adds cargo space without sacrificing passenger comfort
Cons:- Only compatible with cross bar-equipped vehicles
- Limited to 110 lb load capacity
Best for: Owners of vehicles with cross bars who want an easy-to-install, weatherproof cargo solution
Not ideal for: Owners of vehicles without cross bars or those needing higher weight capacity for bulky gear
- Dimensions:53 x 34 x 15 inches
- Load Capacity:110 lbs
- Material:ABS plastic
- Compatibility:Vehicles with cross bars
- Assembly:No tools required
- Finish:Black textured surface
Our verdict“Best suited for casual users with cross bar roofs seeking quick installation and weatherproof storage without heavy loads.”
GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12/14 Cubic Feet, Waterproof Hard Shell
The GarveeTech offers a flexible storage capacity between 12 and 14 cubic feet, making it a balanced choice for those who need more than small carriers but less than the largest options like the Yakima CBX XXL. Its dual-sided opening enhances convenience, especially compared to the smaller INNO WEDGE660, which has a lower capacity. Constructed from durable ABS with UV resistance, it’s suitable for most roof racks, but customer satisfaction seems moderate, possibly due to installation or fit issues. Its 165 lb load capacity aligns with larger cargo boxes, but compatibility checks are essential. This makes sense for users wanting a mid-range capacity with easy access during road trips.
Pros:- Durable waterproof and UV-resistant construction
- Spacious storage of up to 14 cubic feet
- Dual-sided opening for easy access
- Compatible with most roof rack systems
Cons:- Limited to vehicles with roof racks
- Customer feedback indicates moderate satisfaction, possibly due to fit issues
Best for: Travelers needing moderate capacity and dual access on roof rack-equipped vehicles
Not ideal for: Those with very limited cargo needs or vehicles without roof racks, as compatibility may vary
- 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
- Material:ABS plastic
- Includes:2 keys, 2 straps
- Compatibility:Most roof rack vehicles
Our verdict“Best for users seeking a versatile, mid-capacity cargo box with easy dual access and weather protection.”
14 Cubic Feet Hard Shell Roof Cargo Carrier with Security Keys, Waterproof Rooftop Storage Box, Dual Side Opening, White
This 14 cu ft cargo carrier offers a generous amount of space for family trips, rivaling larger models like the Yakima CBX XXL but with a simpler design. Its impact-resistant ABS shell provides weatherproofing, similar to the Garvee, yet it’s slightly smaller in overall dimensions. The dual side opening enhances convenience over traditional rear-only access, and the lockable feature adds security for valuables. However, it may be heavy to handle during installation, especially for solo users, and its white color limits aesthetic options. This makes sense for travelers prioritizing size and security over ultra-lightweight design or color variety.
Pros:- Large 14 cubic feet capacity
- Weather-resistant impact ABS shell
- Easy tool-free installation with dual side access
- Secure lockable design for valuables
Cons:- Heavy to handle during installation
- Limited color options (only white)
Best for: Families or groups needing substantial cargo space with secure locking for extended trips
Not ideal for: Solo travelers or those with limited strength for handling heavy units, or users wanting multiple color options
- Capacity:14 cubic feet
- Dimensions:62.52″L x 32.48″W x 13.19″H
- Max Load Capacity:150 lbs
- Material:Impact-resistant ABS
- Locking:Yes, with keys
- Opening:Dual side
Our verdict“Perfect for users who need ample cargo space with security features for family travel and outdoor adventures.”
INNO WEDGE660 White 11 cu ft Roof Box – Hard Shell, Low Profile, Dual-Side Opening, Made in Japan
The INNO WEDGE660 excels in reducing wind resistance thanks to its low-profile, sleek design, making it an excellent choice for drivers concerned with fuel efficiency. Its 11 cubic feet capacity is smaller than the Garvee or the 14 cu ft options, but it’s easier to install on a variety of roof rack types, including factory and aero racks—something the larger Garvee might struggle with due to bulk. Dual-side opening offers convenient access, but the limited capacity makes it less suitable for larger families or extensive gear. The Japanese craftsmanship ensures quality, but installation may require some adjustment to avoid hatch interference. This model is best for those prioritizing aerodynamics and secure, easy access over maximum cargo volume.
Pros:- Low profile reduces wind resistance and improves fuel economy
- Dual-side opening offers convenient access
- Secure safety lock with key removal
- Compatible with a wide range of roof rack types
Cons:- Limited capacity at 11 cu ft
- Installation may require adjustments for hatch clearance
Best for: Single travelers or small families seeking a low-profile, aerodynamic storage option with quick access
Not ideal for: Large families or those with bulky gear needing maximum capacity
- Capacity:11 cu ft
- Material:Hard shell
- Color:White
- Compatibility:Aero, square, round, factory racks
- Opening:Dual side
- Made in:Japan
Our verdict“Ideal for weight-conscious drivers who want a low-profile, aerodynamic cargo box with reliable security and easy access.”
Thule Force 3 L Cargo Box
The Thule Force 3 L Cargo Box stands out for its durability, sleek design, and user-friendly features, making it ideal for those who prioritize reliability and convenience. Compared with larger options like the Yakima CBX XXL, it offers a more manageable size for everyday use while still providing secure dual-sided access. Its quick, secure mounting system with indicator ensures easy installation, though the setup can be tricky for some first-timers. The SlideLock system adds an extra layer of security, and extensive testing by Thule guarantees safety and durability. However, its limited capacity makes it less suitable for bulky gear or large families. This pick makes the most sense for active consumers who need a dependable, stylish cargo box for regular trips without sacrificing ease of use.
Pros:- Durable and stylish design suitable for daily use
- Easy and secure mounting system with indicator
- Dual-sided access for convenience
- Reliable locking mechanism with security indicators
Cons:- Limited capacity for larger cargo needs
- Potentially complex installation for some users
Best for: Outdoor enthusiasts and daily commuters seeking a durable, stylish cargo box with straightforward access.
Not ideal for: Large families or those needing to haul bulky gear regularly, as the capacity may be too limited.
- Capacity:3 liters
- Mounting System:Quick and secure with indicator
- Locking System:SlideLock with separate locking and opening functions
- Safety Testing:Extensively tested in Thule Test Center
Our verdict“This is the best choice for users who want a reliable, easy-to-use cargo box for regular trips around the city or short adventures.”
Yakima CBX XXL Vehicle Rooftop Cargo Gear Box, 21.5 Cu Ft, Black
The Yakima CBX XXL is the go-to for those needing extensive storage space, offering 21.5 cubic feet for gear such as skis, snowboards, or multiple suitcases. It surpasses smaller models like the Thule Motion 3 in capacity, making it ideal for family trips or ski adventures. Its dual-sided opening allows easy access from either side of the vehicle, streamlining loading and unloading. While its universal mounting hardware ensures compatibility with most crossbars, its sheer size and weight can make handling daunting for solo installers, and the higher price reflects its premium capacity. Only available in black, which may limit aesthetic options. This box is best suited for travelers who prioritize space, even if it means handling a heavier setup.
Pros:- Large storage capacity suitable for multiple travelers
- Dual-sided opening for easy access from either side
- Secure locking with SKS locks for maximum security
- Universal mounting hardware compatible with various crossbars
Cons:- Heavy and large, potentially difficult to handle alone
- Higher price point due to size and features
Best for: Families or groups with significant gear to transport, especially for ski trips or multi-person vacations.
Not ideal for: Single travelers or those with limited roof space, as the size and weight may be cumbersome to install and maneuver.
- Capacity:21.5 Cu Ft
- Dimensions:91 x 38 x 17 inches
- Maximum Gear Length:215 centimeters
- Mounting Hardware:Universal, fits all Yakima StreamLine crossbars and factory or aerodynamic crossbars
- Locking System:SKS locks
Our verdict“This is the best option for those who need maximum capacity and are comfortable managing a heavier, larger cargo box.”
62 Inch Rooftop Cargo Box Carrier, 14 Cu Ft, Heavy Duty, Black
The 62 Inch Rooftop Cargo Box Carrier combines a generous 14 cubic feet of space with durable, impact-resistant construction, making it well-suited for outdoor adventures. Its weatherproof materials and secure lock system protect gear from the elements, comparable to the Garvee 17 Cu Ft model but with a slightly smaller capacity. Its tool-free installation appeals to users who want quick setup, although its weight of over 30 pounds can be a challenge for some to handle alone. Compatibility with crossbars up to 3 inches wide is adequate for most vehicles, but narrow or very wide racks may pose issues. This cargo box is ideal for outdoor enthusiasts who need a tough, weather-resistant carrier, even if it’s less spacious than larger options.
Pros:- Large 14 cubic feet storage capacity
- Durable, weatherproof construction
- Secure lock system with dual-side access
- Easy, tool-free installation
Cons:- Heavy for some to handle during installation
- Limited to crossbars up to 3 inches wide

- Capacity:14 cubic feet
- Weight Capacity:130 lbs
- Material:ABS and PMMA
- Weight:30.2 lbs
- Compatibility:Fits crossbars up to 3 inches wide
Our verdict“This cargo box is a solid pick for outdoor lovers who need tough, weatherproof storage without excessive weight or complexity.”
SportRack Sidekick Rooftop Cargo Box
The SportRack Sidekick offers a compact 8 cubic feet of storage, making it ideal for travelers who need only a small, secure space for essentials like golf clubs or camping gear. Its passenger-side opening simplifies loading, especially on busy roads, and it mounts securely using U-bolts and reinforcement plates, ensuring stability on various factory and aftermarket racks. While it’s easy to handle and install, its 75-pound load capacity limits its usefulness for heavier gear or larger families. Compared with bulkier options like the Thule Motion 3, this model excels in tight spaces but sacrifices capacity. It’s best suited for those who prioritize convenience and a smaller footprint over large cargo volume.
Pros:- Compact, space-saving design
- Secure mounting with U-bolts and reinforcement
- Passenger-side opening for easier loading
- Includes lock for security
Cons:- Limited 75-pound load capacity
- Only 8 cubic feet may be too small for larger gear

- Capacity:8 cubic feet
- Dimensions:54 x 25 x 15.5 inches
- Weight:19.85 pounds
- Load Capacity:75 pounds
- Opening:Passenger-side
Our verdict“This is the best choice for those who want a small, convenient cargo box for light loads and easy access.”
Thule Motion 3 Rooftop Cargo Box
The Thule Motion 3 combines a sleek, aerodynamic wing-shaped profile with advanced mounting and locking features, making it ideal for drivers who value fuel efficiency and ease of use. Its PowerClick quick-mount system with an integrated torque indicator ensures a fast, secure fit, outperforming less sophisticated systems like the Thule Force 3 in ease and speed. The SlideLock system guarantees lid security, and the wide handle allows one-handed operation. While its large footprint may take up significant roof space and accessories like liners or interior lights need to be purchased separately, it offers a premium combination of style, efficiency, and safety. This model is best for frequent travelers who want a high-performance, feature-rich cargo solution.
Pros:- Aerodynamic wing-shaped profile reduces drag and fuel consumption
- PowerClick quick-mount with audible torque indicator for fast installation

- Dimensions:81″L x 38″W x 18″H

- Mounting System:PowerClick quick-mount with torque indicator
- Locking System:SlideLock with separate locking and opening functions

Our verdict“This is the premier choice for drivers who want a stylish, efficient cargo box with advanced features for frequent use.”
SportRack Vista XL Rear Opening Cargo Box, Black
The SportRack Vista XL stands out for its generous 18 cubic feet capacity, making it ideal for families or groups needing substantial storage. Its rear-opening design allows for loading away from traffic, a key safety feature compared to the side-opening Thule Pulse 2 that can be more convenient but offers slightly less volume. The tool-free mounting system simplifies installation, but the 100 lb weight limit is a constraint for heavier gear. It’s compatible with most racks, yet owners should double-check fit, especially on newer factory bars. While it excels in capacity and ease of use, it trades some premium features and styling for practicality and affordability.
Pros:- Large 18 cubic foot cargo capacity for substantial gear
- Rear opening allows safe loading away from traffic
- Tool-free mounting system simplifies setup
- Includes lock and key for added security
Cons:- Limited to 100 lb weight capacity, restricting heavier items
- May not fit all factory racks without checking compatibility
Best for: Families or groups seeking maximum cargo space and straightforward installation for road trips.
Not ideal for: Urban commuters or those with limited rack space, as the box’s size may be cumbersome and hard to fit.
- Capacity:18 cubic feet (510 L)
- Material:UV-resistant ABS
- Dimensions (LxWxH):63 x 38 x 19 in / 160 x 96.5 x 48 cm
- Max Weight Capacity:100 lbs (45 kg)
- Crossbar Spacing:23 5/8 – 29 3/4 in (60 – 75.5 cm)
- Access:Rear opening
Our verdict“This cargo box is perfect for those prioritizing maximum storage and easy rear access, especially on larger vehicles.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft, Dual-Side Opening
The Thule Pulse 2 L offers a streamlined 16 cubic foot capacity with dual-side opening, making it a top choice for drivers who want quick, hassle-free access from either side. Compared with the SportRack Vista XL, it provides less overall volume but excels in ease of loading and offloading, especially in tight parking situations. Its tool-free mounting with a torque indicator ensures a secure fit without guesswork, although it lacks some of the premium features found in higher-end Thule models. The ASA-ABS plastic construction resists weather and scratches, making it durable for regular use. It’s ideal for users seeking reliable, balanced performance without the bulk of larger boxes.
Pros:- Dual-side opening enables easy access from either vehicle side
- Tool-free mounting with audible torque click for security
- Weather-resistant ASA-ABS plastic maintains appearance over time
- Forward design preserves full trunk access
Cons:- Lacks the premium features and larger capacity of Thule’s higher-end boxes
- Limited to 16 cubic feet, slightly less volume than some competitors
Best for: Active travelers who value quick, flexible access to gear and a sleek, vehicle-friendly design.
Not ideal for: Those needing maximum storage capacity or carrying very heavy loads, as the 75 kg limit may be restrictive.
- Capacity:450 litres / 16 cubic ft
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Opening:Dual-side
- Mounting:Tool-free with torque indicator
Our verdict“This pick suits drivers wanting quick, accessible cargo space in a lightweight, durable package for urban and suburban use.”
Thule Force 3 XL Rooftop Cargo Box
The Thule Force 3 XL is built for demanding users who need a tough, secure cargo solution. Its extensive testing at the Thule Test Center guarantees durability under road conditions, a strength over many competing models like the SportRack Vista XL that may not have such rigorous validation. The SlideLock system provides automatic securing, while dual-side access offers flexibility in tight spots. However, its size and weight can make installation and removal more challenging for smaller or less experienced users. Without a detailed review of performance in real-world scenarios, it’s difficult to gauge how well it balances ease of use with ruggedness, but it remains a strong choice for active adventurers who demand reliability.
Pros:- Rigorously tested for durability at the Thule Test Center
- Secure, intuitive SlideLock system confirms proper closure
- Dual-side access simplifies loading and unloading
- Built with tough materials for all-weather performance
Cons:- Limited information on real-world ease of use or installation complexity
- Larger size may be difficult for smaller vehicles or less experienced users
Best for: Adventurers and outdoor enthusiasts who require a durable, secure cargo box for frequent use and challenging conditions.
Not ideal for: Casual users or those seeking lightweight, easy-to-mount options for occasional trips, as the box’s size may be overkill for light loads.
- Brand:Thule
- Model:Force 3 XL
- Size:XL (US)
- Mounting System:Quick-click secure mounting
- Locking System:SlideLock with separate locking and opening functions
- Access:Dual-side opening
Our verdict“This cargo box is best suited for those who prioritize toughness and safety for frequent outdoor adventures.”

How We Picked
I evaluated premium roofcargo boxes based on several criteria relevant to discerning buyers. Performance metrics such as waterproofing, security features, and load capacity were critical, alongside build quality and materials used. Ease of installation, access, and usability also influenced rankings, especially for frequent users. Value was considered by comparing features to price, ensuring that higher-cost models offered meaningful advantages. The selection process aimed to highlight products that excel in durability, functionality, and safety, with a focus on those that suit a variety of vehicle types and usage scenarios.Factors to Consider When Choosing Premium Roofcargo Boxes
Choosing a premium roofcargo box involves more than just capacity. To get the best fit for your vehicle and needs, consider key factors that influence performance, convenience, and longevity. Understanding these aspects can help avoid common pitfalls and ensure your investment pays off over time.Size and Capacity
Size directly impacts how much gear you can carry, but larger boxes may also affect your vehicle’s aerodynamics and fuel efficiency. It’s essential to select a capacity that matches your typical load without overwhelming your vehicle or compromising handling. Keep in mind that a slightly smaller, more aerodynamic box can offer better overall performance if you don’t need maximum volume every trip.
Ease of Access and Opening Mechanisms
Dual-side opening models provide easier access from either side of the vehicle, especially useful in tight parking spaces. However, they often come with increased weight and cost. Consider how frequently you’ll need to load or unload and whether quick, easy access outweighs these tradeoffs. Simpler top-loading designs may be lighter and more straightforward but less flexible.
Security and Waterproofing
High-end roofboxes prioritize secure locking systems and waterproof seals to protect contents from theft and weather. Look for models with robust locks and sealed hinges, especially if you’ll store valuable or sensitive gear. Remember that no waterproof seal is infallible; proper installation and maintenance are necessary to preserve integrity over time.
Material and Durability
Premium boxes usually feature high-quality ABS or fiberglass shells that resist impacts and UV damage. Cheaper materials may crack or degrade faster, reducing lifespan. Investing in a well-made shell can save money long-term, particularly if you frequently travel or park in harsh environments. Be aware that more durable materials often add weight, which can affect handling and fuel economy.
Price and Value
While premium roofcargo boxes tend to be more expensive, they often include features like advanced aerodynamics, security, and sleek designs that justify the cost. Balance your budget against your specific needs, such as capacity and ease of access. Sometimes, paying more upfront results in better performance and longevity, reducing the need for replacements or repairs.
Frequently Asked Questions
How do I choose the right size roofbox for my vehicle?
Start by measuring your vehicle’s roof dimensions and considering your typical cargo volume needs. Larger boxes offer more capacity but can increase wind resistance and reduce fuel efficiency. Think about the type of gear you carry regularly—if it’s bulky or numerous, opt for a higher volume. Remember to account for weight limits specified by your vehicle manufacturer to ensure safe loading.
Are dual-side opening roofboxes worth the extra cost?
Dual-side opening models provide significant convenience, especially when parking in tight spaces or on busy streets. They allow easier access from either side of your vehicle, which can save time and effort. However, they tend to be heavier and more expensive, so consider how often you’ll benefit from this feature versus your budget constraints.
What materials are best for durability in a premium roofbox?
High-quality ABS plastic and fiberglass shells are common in premium models due to their strength and resistance to impact and weather. These materials help maintain the box’s shape and protect contents over years of use. Cheaper plastics may crack or fade quickly, so investing in a shell made from durable, UV-resistant materials generally offers better long-term value.
How important is waterproofing and security in a premium roofbox?
Both features are key for protecting valuable gear during inclement weather or theft attempts. Well-designed seals and locking mechanisms prevent water intrusion and unauthorized access. For frequent or long trips, prioritize models with proven waterproofing and high-security locks, even if they come at a higher price, as they can prevent costly damages or losses.
Should I prioritize aerodynamics over capacity?
Yes, in many cases, an aerodynamically shaped box can significantly improve fuel efficiency and reduce wind noise. If you often travel long distances or want to minimize fuel costs, choosing a low-profile, sleek design is wise. However, if your primary concern is maximum cargo space, you might accept some wind resistance in favor of larger capacity, understanding it may impact fuel economy slightly.
Conclusion
For general use and balanced performance, the Thule Motion 3 offers the best overall combination of capacity, security, and ease of access. The Yakima CBX XXL is ideal for those needing maximum volume, especially for large families or bulky gear. Budget-conscious buyers will find the Garvee Heavy Duty Hard Shell provides reliable durability at a lower price point. Beginners or occasional users should consider simpler, lighter designs, while frequent travelers or those with specific security needs should prioritize models with advanced waterproofing and locking systems. Evaluating your typical trips and cargo needs will help you select the perfect premium roofcargo box.
