Thule Force XT Cargo Box
The Thule Force XT stands out for its robust, sleek design that combines durability with everyday practicality. Its quick, secure mounting system and automatic locking make it a favorite for frequent travelers who value safety and convenience. Compared with the Thule Pulse 2 M, the Force XT offers a larger capacity and more premium build quality, but it comes at a higher price and is heavier to install alone.

TUFFIOM 13.4 cu.ft. Rooftop Cargo Box
The TUFFIOM 13.4 cu.ft. Cargo Box offers a balanced mix of capacity, security, and weatherproofing at a competitive price. Its durable ABS shell and keyed lock system provide peace of mind, especially when compared with the Thule Pulse 2 M, which is more expensive and slightly smaller. The TUFFIOM’s dual-side opening simplifies loading, but it requires peeling off protective film before use, which can be a minor hassle. Its 150 lbs weight limit makes it suitable for most gear but less ideal for very heavy loads. This model suits budget-conscious buyers who still want weather protection and security for their valuables.
Pros:- Dual-side opening for easy access

The TACMOLLE 21 Cubic Feet Waterproof Soft Roof Bag offers unmatched versatility, fitting all vehicles with or without roof racks. Its soft-shell design allows it to fold into a compact storage bag, making it ideal for those who need a flexible, space-saving option. Compared with rigid boxes like the Thule Force XT, this bag sacrifices some rigidity but gains in universal fit and storage convenience. Made from tearproof 840D PVC fabric with welded seams, it keeps belongings dry even in heavy rain, but its lack of precise dimensions can make fitting on certain vehicles tricky. This is best suited for travelers prioritizing flexibility and storage capacity over rigidity.

Our verdict“This soft roof bag excels for users needing flexible, waterproof storage on various vehicle types with maximum capacity.”

The Thule Pulse 2 M offers a practical 14 cubic feet of storage, making it well-suited for ski gear, luggage, or snowboards. Its weather-resistant ASA-ABS plastic ensures longevity and protection against the elements. The tool-free attachment system with torque indicator simplifies installation, a step up from simpler models like the SportRack Vista XL. However, its weight and limited color options can be drawbacks for solo installation or aesthetic preferences. This cargo box strikes a balance between size and ease of use, ideal for winter sports enthusiasts or light travelers who need reliable, weatherproof gear storage.
Pros:- Large 14 cubic feet capacity for gear
- Easy tool-free installation with torque indicator
- Weather-resistant ASA-ABS plastic construction
Cons:- Heavy to handle alone during installation

- Capacity:14 Cubic Ft
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Color:Black
Our verdict“This cargo box is ideal for winter sports fans or small groups seeking a reliable, easy-to-use solution for gear transport.”
Thule Pulse 2 L Roof Mounted Cargo Box
The Thule Pulse 2 L provides 16 cubic feet of streamlined storage, making it a solid choice for weekend getaways or daily commuting. Its weather-resistant ASA-ABS construction ensures durability, while the dual-side opening offers quick access from either side of the vehicle. Compared to the Thule Pulse 2 M, the Pulse 2 L offers slightly more space but shares similar features. Its 75 kg load capacity suits most standard gear but might fall short for heavy or bulky items. This model is well-suited for those needing a compact yet spacious cargo box that is straightforward to install and access.
Pros:- Easy to install with tool-free system
- Provides ample space for various gear
- Weather-resistant and durable
Cons:- Limited to 75 kg load capacity

Our verdict“This cargo box is perfect for casual users needing reliable, weatherproof storage for weekend trips or daily routines.”
Thule Force 3 XL Cargo Box
The Thule Force 3 XL stands out for its robust construction and versatile usability, making it ideal for frequent travelers and active families. Its durable, weather-resistant material ensures protection against the elements, while the Quick, secure mounting system with safety indicators simplifies installation, especially compared to bulkier options like the FIVKLEMNZ soft bag. The dual-side access adds convenience but can make the box larger, requiring more roof space and potentially complicating fitting on smaller vehicles. Compared to the Thule Motion 3, this model emphasizes durability and straightforward mounting, though it may lack some of the aerodynamic benefits of the latter. It’s a reliable choice for those prioritizing security and ease of access, but users with limited roof space should consider its size.
Pros:- Durable, weather-resistant construction suitable for frequent use
- Easy and secure mounting with safety indicators
- Provides convenient access from both sides
Cons:- Large size may require significant roof space and clearance
- Installation could be challenging for some users due to size

- Capacity:up to 16 cubic feet
- Mounting System:Quick, secure, and intuitive with indicator
- Locking System:SlideLock with separate locking and opening functions

Our verdict“This box is an excellent choice for users seeking a durable, secure, and easy-to-use cargo solution for regular use.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 offers a sleek, aerodynamic profile that reduces drag and boosts fuel efficiency—especially beneficial compared to bulkier carriers like the Auto Dynasty box. Its quick-mount system and torque indicator make installation straightforward, even for those new to roof boxes. With a spacious interior and included accessories, it caters well to adventure seekers and those needing a stylish, durable carrier. However, the limited weight capacity isn’t highlighted prominently, and its price point might be a barrier for budget-conscious shoppers. If you prioritize streamlined design and longevity, the Motion 3 is compelling, though users with larger or heavier gear may find it limiting compared to larger models like the Thule Force 3 XL.
Pros:- Aerodynamic shape reduces drag and improves fuel economy
- Easy to mount with quick-mount system and torque indicator
- Spacious, durable, and includes convenient accessories
Cons:- Limited details on maximum weight capacity
- Price might be high for budget shoppers
Best for: Modern adventurers who value style, ease of installation, and fuel efficiency.
Not ideal for: Heavy-duty users needing maximum capacity or those on tight budgets, as it may be pricier than others like the Auto Dynasty box.
- Dimensions:81″L x 38″W x 18″H
- Material:Durable, weather-resistant
- Warranty:Limited Lifetime
Our verdict“Ideal for style-conscious users seeking a durable, aerodynamic cargo box that enhances fuel efficiency and ease of use.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ 21 Cubic Roof Bag offers impressive capacity and waterproof protection, making it an excellent choice for rugged road trips and camping, especially compared to hard-shell options like the GarveeTech box. Its 840D PVC material and welded seams give it a high level of water resistance, while the complete travel kit simplifies setup. However, its soft-sided design means it might be less secure than rigid boxes, with a potential for wind noise and security concerns at high speeds. Installation requires careful attention to straps and placement, and it may not fit smaller vehicles comfortably. This model suits those prioritizing flexibility, large capacity, and budget-friendly options over absolute security or aerodynamic efficiency.
Pros:- Highly waterproof with welded seams and durable PVC material
- Large capacity to hold multiple suitcases and gear
- Complete travel kit included for easy setup
Cons:- Requires careful installation to ensure security
- Potential wind noise at high speeds
- Size may be too large for small vehicles
Best for: Road travelers, campers, and outdoor enthusiasts needing a large, waterproof cargo solution that adapts to various vehicles.
Not ideal for: Urban drivers with small cars or those seeking a rigid, security-focused cargo box for high-speed travel.
- Material:840D PVC
- Capacity:21 cubic feet
- Dimensions:52 x 40 x 18 inches
- Includes:Anti-slip mat, luggage lock, reinforced straps, door hooks, storage bag
Our verdict“This soft roof bag excels for large capacity and waterproof protection, ideal for adventurous travelers with ample roof space.”
GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity
Compared with the Thule Force 3 XL, the GarveeTech Cargo Box offers a slightly smaller capacity but emphasizes heavy-duty, weather-resistant protection with its sturdy ABS shell. It’s well-suited for users who need a reliable, waterproof hard shell with dual-side openings for quick access, especially on rougher roads. Its 165-lb weight capacity makes it suitable for bulkier loads, though the limited warranty period of 30 days might concern some buyers. The aerodynamic design helps reduce noise and drag, but verification for roof rack compatibility is necessary—it’s best for those who already have compatible racks and prioritize durability over brand prestige.
Pros:- Durable, weather-resistant ABS shell
- Large 12 cubic feet capacity and high weight limit
- Dual-sided opening for quick access
Cons:- Limited 30-day warranty period
- Roof rack compatibility verification needed
Best for: Heavy-duty travelers or outdoor enthusiasts needing tough, weatherproof storage with easy access on a budget.
Not ideal for: Those seeking a long-term warranty or a lightweight carrier for light, occasional use, as the warranty period is short.
- Capacity:12 cubic feet
- Weight Capacity:165 lbs
- Dimensions:54.3 in L x 31.5 in W x 13.4 in H
- Opening:Dual-sided
Our verdict“A robust, weatherproof hard shell cargo box suited for demanding conditions and heavy loads, ideal for serious outdoor adventures.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
The Auto Dynasty Cargo Carrier offers a straightforward, budget-friendly option with 11 cubic feet of storage, making it suitable for casual travelers and families on a budget. Its UV-protected, impact-resistant ABS shell provides reliable protection against the elements and impacts, comparable to pricier models like the Thule Motion 3 but with fewer premium features. The wide 14-inch opening simplifies loading, though its installation might require careful measurement, especially since it fits only cross bars up to 13 inches wide. This box is perfect for those who need reliable, impact-resistant storage without the bells and whistles, but it’s less suitable for high-mileage or long-term use where durability and advanced features matter more.
Pros:- Impact-resistant, UV-protected ABS shell
- Wide 14-inch opening for easy loading
- Affordable, reliable protection
Cons:- Fits only cross bars up to 13 inches wide
- Potentially heavier to install due to size
Best for: Budget-conscious families or casual travelers needing a simple, impact-resistant cargo box for occasional use.
Not ideal for: Frequent travelers or those with larger roof racks, as its compatibility is limited, and it may lack some durability for long-term use.
- Dimensions:53″ L x 34″ W x 15″ H
- Capacity:11 Cubic Feet
- Material:UV-protected ABS
Our verdict“A practical, impact-resistant cargo box ideal for budget-friendly, casual use on vehicles with compatible roof racks.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL stands out for its generous 18 cubic foot capacity, making it an excellent choice for families needing to carry bulky gear or multiple suitcases. Its rear-opening design simplifies loading and unloading, especially when parked close to obstacles, unlike the SportRack Sidekick, which offers less space but excels in compact storage. The tool-free mounting system adds convenience, but its weight can be a challenge to handle solo, and compatibility depends on specific crossbar spacing. The durable UV-resistant ABS material ensures longevity, though the box’s size requires ample roof space and may not fit all rack configurations.
Pros:- Large 18 cubic foot storage capacity for bulky gear
- Easy rear access for quick loading
- Tool-free installation speeds up setup
- Secure lock and key included for safety
Cons:- Heavy to handle alone, especially during installation
- Compatibility limited to certain crossbar spacings
- Requires sufficient roof crossbar width
Best for: Families or groups who need maximum storage capacity and easy rear access during trips
Not ideal for: Solo travelers or those with limited rack space, due to its weight and size
Our verdict“This cargo box is best suited for users prioritizing capacity and rear accessibility over ease of handling.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
The Hard Shell Roof Top Cargo Carrier offers a solid 110 lbs load capacity and a durable ABS construction, making it ideal for travelers who need reliable weather protection. Compared with the MIDABAO 20 Cubic Waterproof Carrier, which provides more volume, this box emphasizes security and straightforward installation, especially for vehicles with cross bars. Its limited color options and lack of interior padding are tradeoffs for its robust waterproofing and security features, but it is only compatible with vehicles equipped with cross bars. This makes it less versatile for those with soft or rackless setups.
Pros:- Durable, weather-resistant ABS construction
- Easy to install without tools on cross bars
- Secure lock provides peace of mind
- Rigid shell offers good protection against elements
Cons:- Limited to vehicles with cross bars
- No interior padding or insulation
- Limited color options
Best for: Travelers seeking durable, weatherproof cargo protection with simple installation on cross bar-equipped vehicles
Not ideal for: Owners of vehicles without cross bars or those needing softer, more flexible storage solutions
Our verdict“Ideal for users who prioritize weatherproof hard shell protection and straightforward mounting.”
MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks
The MIDABAO 20 Cubic Waterproof Carrier offers an expansive 20 cubic feet of room, suited for travelers with vehicles that may lack roof racks or require adaptable storage. Its PVC material provides waterproofing, and its malleable form simplifies storage when not in use. Unlike the hard shell options like the Thule Force XT, this soft carrier can be stored easily and fits a wide range of vehicles, though it may need multiple straps to stay secure and is less durable against sharp objects or extreme conditions. Its flexible design makes it a versatile choice for those who need extra space without permanent mounting.
Pros:- Large 20 cubic feet capacity for maximum cargo
- Waterproof PVC material keeps belongings dry
- Flexible, easy to store when not in use
- Simple mounting with included straps
Cons:- May require multiple straps for stability
- Less durable than hard shell carriers
- Limited color options
Best for: Travelers needing a large, waterproof, and flexible cargo solution that fits various vehicle types
Not ideal for: Users requiring maximum security or a rigid shell for heavy or sharp items
Our verdict“Best suited for those seeking a large, waterproof soft carrier with flexible storage options.”
SportRack Sidekick Cargo Box
The SportRack Sidekick provides 8 cubic feet of storage, making it perfect for small loads like golf clubs or camping gear. Its compact dimensions and passenger-side opening facilitate easy loading in tight spaces, unlike larger boxes such as the SportRack Vista XL. However, its limited capacity restricts it to smaller cargo, not suitable for bulky or multiple items. Its lightweight design at under 20 pounds allows for easier handling, but this also means it may not withstand very heavy loads or rough conditions as well as hard shell options. It fits a variety of rack systems but is best for minimal, quick-access storage needs.
Pros:- Compact and space-saving design
- Passenger-side opening simplifies loading
- Lightweight for easy handling
- Secure lock protects contents
Cons:- Limited load capacity for larger or bulky items
- Only suitable for small cargo
- Less protection against weather compared to hard shells
Best for: Individuals or couples with modest cargo needs who value ease of use and space efficiency
Not ideal for: Families or users with large gear loads, due to its limited capacity
Our verdict“Ideal for small loads and quick access, but not for those needing large or heavy cargo capacity.”
How We Picked
The products in this roundup were evaluated based on several criteria that matter to the typical roof cargo box buyer. Performance factors include capacity, weatherproofing, and security features. Usability was assessed through ease of installation, access, and maintenance. Build quality and durability were also crucial, especially for long-term use. Value was determined by balancing features against price, ensuring options suit different budgets without sacrificing essential qualities. Finally, versatility and compatibility with various vehicle types influenced the rankings, helping to identify which models are best suited for specific needs and lifestyles.Factors to Consider When Choosing Roof Cargo Box
Choosing the right roof cargo box involves weighing multiple factors beyond just capacity. Size and shape should match your vehicle’s roof and your trip requirements, preventing overhangs or instability. Weatherproofing is essential if you plan to travel in rain or snow; look for sealed, waterproof materials rather than just water-resistant fabric. Security features like locks can protect your belongings from theft, especially during stops or overnight stays. Ease of use, including dual-side opening and quick mounts, can save time and effort. Lastly, consider your budget—higher-priced models often offer better durability and features, but there are solid options for every price point.Capacity and Size
Matching your cargo box size to your vehicle and trip length is fundamental. Overly large boxes can cause wind resistance and handling issues, while too small might not provide enough space. Think about how much gear you typically carry; for family vacations, a larger capacity (above 16 cubic feet) is often necessary. Additionally, consider the shape—some models are more aerodynamic, reducing drag and noise. Always measure your roof’s available space and check weight limits to ensure compatibility and safety.
Weatherproofing and Durability
Since roof cargo boxes are exposed to the elements, weatherproofing becomes a priority. Hard-shell models with sealed edges and durable materials like ABS or fiberglass resist rain, snow, and UV rays better than soft-sided options. Soft bags, while easier to store and lighter, are more vulnerable to water and damage from road debris. If you frequently travel in unpredictable weather, investing in a fully waterproof, rugged model will pay off in the long run. Be sure to check for reinforced locks and secure mounting hardware to withstand harsh conditions.
Ease of Installation and Access
Quick and secure mounting is essential, especially if you frequently swap between vehicles or make multiple trips. Some models feature tool-free or minimal-tool setups, saving time and effort. Dual-side opening designs improve convenience, allowing access from either side of the vehicle—particularly useful in tight parking spaces. Consider whether the box is lightweight enough for you to handle alone or if you’ll need assistance. Easy-to-clean surfaces and straightforward lock mechanisms also enhance daily usability.
Security and Locking Features
Security features protect your belongings from theft, especially during overnight stops or unattended parking. High-quality locks integrated into the lid prevent tampering, and some models include keyed locks for added peace of mind. However, more advanced locking systems often come with higher costs and complexity. If you frequently travel in urban or remote areas, prioritize models with reinforced locks and sturdy mounting brackets. Remember, a well-secured cargo box can discourage opportunistic theft and protect your gear.
Price and Value
Prices for roof cargo boxes range from budget-friendly soft bags to premium hard-shell models with advanced features. Consider what features are most important to your use case—capacity, weatherproofing, ease of access—then compare options within your budget. Cheaper models might lack durability or security but can be suitable for occasional use or short trips. Conversely, investing in a more expensive, durable model pays off if you frequently travel or carry valuable items. Balancing cost with expected longevity and performance helps ensure satisfaction over time.
Frequently Asked Questions
Can I install a roof cargo box on any vehicle?
Most roof cargo boxes are designed to fit a wide range of vehicles, but compatibility depends on your roof type and weight capacity. Vehicles with standard roof rails or crossbars are generally suitable, but it’s essential to check your vehicle’s roof load limit to avoid overloading. Some models include universal mounting systems that adapt to various setups, while others require specific hardware. Always measure your roof’s dimensions and compare with the cargo box to ensure a proper fit. If your vehicle lacks suitable mounting points, aftermarket racks may be necessary, adding to the overall cost.
How do I prevent a roof cargo box from causing wind noise or drag?
Choosing an aerodynamic design reduces wind resistance, noise, and fuel consumption. Hard-shell models with rounded edges tend to cut through the air more efficiently than boxy designs. Properly mounting the box close to the roof and ensuring it is well-secured also minimizes movement that can cause whistling or rattling. Some manufacturers offer sleek, low-profile options explicitly designed to reduce drag. Regularly checking mounting hardware and adjusting as needed keeps the box stable, further diminishing unnecessary noise or turbulence during driving.
Are soft roof bags as secure as hard-shell boxes?
Soft roof bags are generally less secure than hard-shell cargo boxes because they lack rigid walls and sophisticated locking mechanisms. They rely on straps and internal compartments, making them more vulnerable to theft or damage in severe weather. However, soft bags excel in portability and ease of storage when not in use, and they are often lighter and less expensive. If security and weatherproofing are priorities, a hard-shell box provides better protection—though soft bags can be suitable for short-term or less critical trips when used with additional locks or security measures.
What is the best way to maintain my roof cargo box?
Regular maintenance involves cleaning the exterior to remove dirt, grime, and road salts that can degrade the materials over time. Use mild soap and water, avoiding harsh chemicals that could damage the surface. Check the mounting hardware and locks periodically to ensure they are secure and functioning smoothly. If your model is waterproof, inspect seals and gaskets for signs of wear and replace them if necessary. Storing the cargo box in a dry, sheltered place when not in use prolongs its lifespan and keeps it looking new for many seasons.
Conclusion
The choice of a roof cargo box depends heavily on your specific needs and budget. The Thule Force XT remains the best overall option for families or frequent travelers who prioritize durability, capacity, and security. For budget-conscious shoppers, a waterproof soft bag like the Rooftop Cargo Bag offers decent protection at a lower price. If you want a premium, feature-rich model, the Thule Motion 3 provides excellent aerodynamics and security for serious adventurers. Beginners or occasional users may prefer smaller, easier-to-install models like the SportRack Sidekick. Ultimately, selecting the right cargo box boils down to matching features to your specific travel style and vehicle compatibility.
