It shares dimensions and build quality with the previous model but is distinguished by its focus on secure, straightforward mounting. Compared to the Thule Force 3 XL, it’s more aerodynamic but offers similar capacity. Customer reviews highlight that mounting can occasionally be tricky for first-timers, but the secure slideLock system provides confidence in lid closure.

The GarveeTech Cargo Box offers a robust ABS shell that ensures waterproof and UV-resistant protection, making it an excellent choice for unpredictable weather. With a capacity of 12 cubic feet and a maximum weight of 165 lbs, it’s well-suited for heavy or bulky gear. Its dual-sided opening enhances access, complemented by included keys and straps for added security. Compared with the Thule options, it prioritizes waterproofing and capacity over aerodynamics or brand prestige. The main tradeoff is its shorter warranty and the need to verify roof rack compatibility. This model makes sense for budget-conscious users who need weatherproof security and substantial load capacity.
Pros:- Waterproof and UV-resistant construction
- Generous 12 cubic feet of storage
- Dual-sided opening for easier access
Cons:- Limited one-year warranty period

Our verdict“This cargo box offers waterproof reliability and a large capacity at a more affordable price point for rugged outdoor use.”
Thule Pulse 2 L Roof Mounted Box
The Thule Pulse 2 L offers a sizable 16 cubic feet of capacity, making it suitable for larger items like skis or luggage. Its dual-side opening design allows for quick access from either side, enhancing convenience during busy loading or unloading scenarios. The weather-resistant ASA-ABS plastic ensures gear stays protected. Compared to the Thule Force 3 XL, it provides similar capacity but emphasizes easy access with its dual-sided feature. The main tradeoff is its bulk, which might be a concern for smaller vehicles, and it requires a roof rack for installation. This box suits drivers needing maximum space and straightforward access, especially for winter sports gear.
Pros:- Large 16 cubic feet capacity for bulky gear
- Dual-side opening for quick access
- Weather-resistant ASA-ABS plastic construction
Cons:- Bulky, may be cumbersome on smaller vehicles
- Requires existing roof rack for installation
Best for: Owners of larger vehicles or SUVs needing substantial cargo space with easy dual-side access
Not ideal for: Small cars or those with limited roof rack capacity, due to its size and bulk

- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
Our verdict“A large-capacity, dual-access cargo box ideal for owners of bigger vehicles carrying substantial gear frequently.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL stands out for its impressive 18 cubic foot capacity, making it ideal for families or groups needing substantial storage. Its durable, UV-resistant ABS material ensures long-lasting use, while the rear-opening design simplifies access to belongings without removing the entire box—especially convenient during frequent stops. Compared with the Thule Force 3 L, this model offers more space but is somewhat limited by its fit—only compatible with specific rack systems. The tool-free installation makes setup quick, but the 100-pound weight limit can restrict heavy loads, which might be a concern for those hauling bulky gear. Overall, this cargo box fits users prioritizing capacity and ease of access over universal compatibility or ultra-lightweight design.
Pros:- Large 18 cubic foot capacity for substantial gear
- Durable UV-resistant ABS construction
- Rear opening for effortless access
- Tool-free installation for quick setup
Cons:- Fits only specific rack systems, limiting versatility
- Maximum weight limit of 100 pounds may restrict heavy cargo
Best for: Families or outdoor enthusiasts needing large-volume storage with easy rear access
Not ideal for: Owners of smaller or less compatible racks who need a lightweight, universal solution
- Capacity:18 cubic feet (510 L)
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 in / 160 x 96.5 x 48 cm
- Max Weight Capacity:100 pounds (45 kg)
- Min-Max Crossbars Spacing:23 5/8 – 29 3/4 in (60 – 75.5 cm)
Our verdict“This is a strong choice for those needing maximum capacity and easy rear access, provided their rack system is compatible.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
The Auto Dynasty Hard Shell Roof Top Carrier offers 11 cubic feet of protected storage, making it suitable for travelers seeking security and weather resistance. Its impact-resistant ABS and secure lock system provide peace of mind in various conditions, and the large opening simplifies loading and unloading. Compared to the SportRack Vista XL, it provides less space but better security and weatherproofing. Its compatibility with cross bars up to 13 inches wide suits many vehicles, yet the limited width might exclude some larger racks. Easy installation and a variety of security features make this a good choice for users prioritizing safe, weatherproof storage over maximum capacity.
Pros:- Secure lock system for valuables
- Impact-resistant ABS material for durability
- Weather-resistant construction for outdoor protection
- Easy tool-free installation
Cons:- Limited to cross bars up to 13 inches wide

Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
The Hard Shell Waterproof Travel Luggage Box provides a straightforward, weatherproof storage solution with a spacious capacity of 110 lbs. Its durable ABS plastic and secure key lock create a sealed environment, ideal for rough weather or long trips. Unlike the Impact-resistant Auto Dynasty model, this option emphasizes simplicity and robustness, with a universal fit on cross bars. Its design lacks internal compartments or padding, making it better suited for bulkier, less delicate cargo. While easy to install on vehicles with cross bars, it may require multiple straps for stability—potentially more time-consuming than other quick-mount options like the Thule Force 3 L. This model fits users who need reliable, weatherproof storage without fuss or complex features.
Pros:- Weather-resistant ABS plastic construction
- Secure key lock for safety
- Easy to install on cross bars
- Spacious capacity for bulky cargo
Cons:- Requires multiple straps for secure attachment
- No internal compartments or padding for delicate items
Best for: Travelers demanding durable, weatherproof cargo with straightforward installation

- Material:ABS plastic
- Capacity:110 lbs
- Dimensions:53 inches x 34 inches x 15 inches

MIDABAO 20 Cubic Waterproof Car Roof Top Carrier
The MIDABAO 20 Cubic Waterproof Roof Top Carrier excels for its enormous 20 cubic feet capacity, ideal for long trips with bulky gear. Its PVC-coated, waterproof design ensures contents stay dry even in heavy rain, surpassing many rigid boxes with its flexible, foldable nature—making storage and transport more convenient when not in use. Unlike the rigid Auto Dynasty or SportRack models, this cargo bag adapts to a variety of vehicles, with or without racks, using six wide straps and two 3M straps for secure attachment. However, its reliance on straps means installation might take longer, and it offers less protection against impacts or theft compared to hard-shell options. This bag suits those needing maximum capacity and weatherproofing in a lightweight, stowable package.
Pros:- Huge 20 cubic feet capacity for bulky gear
- PVC-coated waterproof material
- Flexible, foldable design for easy storage
- Includes anti-slip mat and multiple straps for stability

Not ideal for: Owners seeking a rigid, impact-resistant shell or internal organization features
- Capacity:20 Cubic Feet
- Dimensions:51.1” x 39” x 17”
- Material:PVC coated
- Includes:Anti slip mat, mounting straps
- Number of Straps:6 wide straps, 2 3M straps
Our verdict“Perfect for users prioritizing maximum, waterproof cargo capacity with flexible storage options, especially for longer trips.”
Thule Force 3 L Cargo Box
The Thule Force 3 L offers a compact yet reliable solution for active owners, with a 3-liter capacity suitable for smaller cargo. Despite its limited size compared to others in this roundup, it excels in quick, secure access thanks to its intuitive SlideLock system that automatically locks when closed. Its dual-side opening provides convenience during busy trips, and Thule’s reputation for safety and durability adds confidence. However, the small capacity makes it unsuitable for larger gear or extended trips, which is a limitation compared to the larger, more cargo-oriented options like the SportRack Vista XL or MIDABAO bag. This model makes the most sense for daily commuters or minimalists who value ease of use and security over volume.
Pros:- Durable, weather-resistant construction
- Easy to mount and secure with a quick click
- Convenient dual-side access
- Trusted brand with safety-tested features
Cons:- Limited capacity at just 3 liters
- More expensive relative to its small size

Not ideal for: Those requiring substantial storage for long trips or bulky equipment
- Capacity:3 liters
- Mounting System:Quick, secure, and intuitive
- Locking System:SlideLock with separate locking and opening
- Safety Features:Automatically locks and indicates when securely closed
Our verdict“Ideal for active users wanting a compact, secure, and quick-access roof box, but not suitable for large cargo needs.”
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
The TUFFIOM 13.4 cu.ft. cargo box stands out for offering a solid balance of capacity and security at an accessible price point, making it a strong alternative to pricier options like the Yakima SkyBox NX XXL. Its waterproof ABS shell ensures protection against the elements, and the dual-side opening simplifies loading from either side, a feature not available on all models. Unlike some premium models, it requires crossbars for installation, which might add to setup time, and the protective film on the lid needs removal before use. Compared to larger options, its 13.4 cu ft capacity might be limiting for bigger families, but for moderate trips, it provides ample space. The locking system with keys enhances security for valuables, making it suitable for those who prioritize safety without a high price tag.
Pros:- Easy dual-side access for loading and unloading
- Secure locking system with keys enhances valuables’ safety
- Durable waterproof ABS material ensures long-lasting use
- Streamlined design reduces drag and noise during travel
Cons:- Requires crossbars on vehicle for installation, adding setup complexity
- Protective film on lid needs to be peeled off before use, which is an extra step
Best for: Budget-conscious families or solo travelers who need reliable security and weather protection without extra bells and whistles.
Not ideal for: Large groups or extended trips requiring maximum cargo space, as its 13.4 cu ft capacity may fall short.
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Material:ABS
- Max Load Capacity:150 lbs
- Weight:24.25 lbs
- Locking System:Yes, with keys
Our verdict“This cargo box is ideal for budget-minded users seeking reliable security and weather resistance for moderate trips.”
Yakima SkyBox NX XXL Rooftop Cargo Carrier Hard Shell Box with SKS Locks
The Yakima SkyBox NX XXL excels in providing a generous 22 cu ft of storage, making it a prime choice for families or outdoor enthusiasts needing to carry large gear or skis up to 215 cm long. Its dual-sided access simplifies loading, especially when space is tight on smaller vehicles, and the integrated SKS locks add a layer of security that surpasses basic locking mechanisms. In comparison with the TUFFIOM model, the SkyBox offers nearly double the capacity but may be noticeably bulkier, which could complicate installation on compact cars. Its sleek, durable construction resists weather and impacts well, though the size can make it less agile for quick trips or on smaller vehicles. For those prioritizing space and security, especially during winter sports trips, this box makes a compelling option.
Pros:- Spacious 22 cu ft capacity accommodates large gear and skis
- Dual-sided access simplifies loading and unloading
- SKS locks provide enhanced security for valuables
- Strong, weather-resistant construction withstands harsh conditions
Cons:- Size can be difficult to fit on smaller or lower-profile vehicles
- Limited color options may not match all vehicle aesthetics
Best for: Families or outdoor lovers needing maximum cargo space and enhanced security for large gear and skis.
Not ideal for: Drivers with small or low-clearance vehicles who might find the size bulky or difficult to install.
- Storage Capacity:22 cu ft
- Max Gear Length:215 cm
- Lock Type:SKS Locks

Our verdict“This cargo box suits large families or adventurers seeking maximum space and security for extended outdoor trips.”
How We Picked
I evaluated these rooftop cargo boxes based on several criteria that matter most to consumers: security features, build quality, capacity, ease of installation, and overall value. We prioritized products with reliable locking mechanisms, weatherproof shells, and compatibility with a wide range of vehicles. Our rankings reflect a balance between these features, with higher scores given to options that excel in security and durability without overly sacrificing affordability or ease of use. Products with user-friendly features like dual-side opening and straightforward installation were also favored, helping ensure the selection covers different buyer needs and budgets.Factors to Consider When Choosing Rooftop Cargo Boxes With Locks
Choosing the right rooftop cargo box with locks involves more than just picking the biggest or most secure-looking model. Key factors such as capacity, security, ease of installation, and compatibility can significantly influence your satisfaction and convenience. Understanding these elements helps prevent common mistakes like overpaying for features you don’t need or selecting a size that doesn’t fit your vehicle or gear. This guide highlights the most important considerations to keep in mind when making your decision, ensuring you select a cargo box that matches your specific travel needs.Capacity and Size
Assessing how much gear you need to carry is the first step. Larger boxes provide more room but often come with increased weight and installation complexity. Measure your vehicle’s roof to ensure the cargo box will fit comfortably without obstructing sunroofs or antennas. Remember, a bigger box might mean more wind resistance and fuel consumption, so balance your storage needs with your vehicle’s performance. For occasional use or smaller vehicles, a compact model may suffice, while frequent travelers will benefit from larger, more spacious options.
Security Features
Locks are the core security feature in these boxes, but not all locks offer the same level of protection. Look for high-quality, tamper-resistant locking mechanisms, ideally with keys that are unique or retractable. Some premium models include integrated SKS (Same Key System) locks, allowing you to use a single key for multiple accessories. It’s also wise to check if the lock mechanism is weatherproof and resistant to corrosion, especially if you often drive through harsh conditions. A solid lock system can deter theft and keep your gear safe during stops or overnight stays.
Build Quality and Weatherproofing
Durability hinges on the materials used and the construction quality. Hard-shell cargo boxes made from high-density polyethylene or fiberglass tend to withstand impacts and harsh weather better than fabric or soft-sided options. Ensure the seams and locking areas are sealed tightly to prevent water ingress, which can damage your gear. UV resistance is also important to prevent cracking or fading over time. Investing in a well-built, weatherproof model can extend the lifespan of your cargo box and protect your belongings in all seasons.
Ease of Installation and Use
Installing a rooftop cargo box should be straightforward, especially if you frequently switch between vehicles or need to set up quickly. Look for models with a universal mounting system compatible with most roof racks. Dual-side opening can significantly improve usability, allowing access from either side of the vehicle. Keep in mind that some larger models may require additional help or tools for installation. Consider how easily the box can be removed and stored when not in use, especially if you need to free up roof space or park in tight spaces.
Price and Value
Price ranges widely based on size, material, lock quality, and brand reputation. While it’s tempting to choose the cheapest option, very low-cost models often compromise on security or durability. Conversely, premium models offer enhanced features but at a higher cost. Focus on finding a balance that matches your budget while meeting your security and capacity needs. Sometimes, investing a bit more upfront saves money in the long run by avoiding frequent repairs or replacements.
Frequently Asked Questions
Will a rooftop cargo box fit on my vehicle?
Most rooftop cargo boxes are designed to be universal, but compatibility depends on your vehicle’s roof rack system and available space. Measure your roof’s width and height, then compare it with the cargo box’s dimensions to ensure a proper fit. Many models specify the maximum crossbar spread they can accommodate. If your vehicle has a factory-installed roof rack, check its specifications for weight capacity and compatibility. When in doubt, consult the manufacturer’s guidelines or seek professional installation advice to avoid issues later.
How secure are the locks on these cargo boxes?
Lock quality varies among models, with premium options offering more resistance to tampering and theft. Look for locks with features such as keyed locking mechanisms, tamper-resistant cylinders, and weatherproof seals. Some high-end boxes include SKS locks, allowing you to use a single key across multiple accessories, adding convenience and security. Regular maintenance, like lubricating locks and checking for corrosion, also helps keep your cargo safe. Remember, no lock is completely theft-proof, but choosing a well-made lock significantly reduces risks.
Can I install a cargo box myself without special tools?
Many rooftop cargo boxes come with mounting hardware and detailed instructions that make DIY installation feasible for most vehicle owners. Dual-side opening models tend to be easier to access and install. However, larger or heavier boxes may require additional help or specialized tools such as a ladder or power drill. Make sure your roof rack is compatible and properly rated for the weight of the cargo box plus your gear. If you’re unsure, many retailers or professional installers can assist with mounting, ensuring safety and proper fit.
How weather-resistant are these cargo boxes?
Most high-quality cargo boxes are designed to withstand rain, snow, and UV exposure, thanks to their durable, weatherproof shells. Materials like high-density polyethylene or fiberglass are common choices for their resilience. Sealed seams and locking mechanisms prevent water from entering, protecting your belongings. However, cheaper models may lack proper sealing, leading to leaks over time. Regular inspections and maintenance, like applying lubricants and sealing any gaps, can help preserve weather resistance over the years.
When should I choose a soft-sided versus a hard-shell cargo box?
Hard-shell cargo boxes generally offer superior security, weatherproofing, and protection against impacts, making them ideal for frequent use or valuable gear. Soft-sided options tend to be lighter, easier to store when not in use, and less expensive, but they often lack the same level of security and weather resistance. Consider a hard-shell box if you prioritize security and longevity, especially in harsh climates. Soft-sided models can work well for occasional trips or when weight and storage space are primary concerns, but they may require more careful handling and maintenance.
Conclusion
For most buyers seeking a reliable, secure rooftop cargo box, the Thule Force 3 XL offers an excellent all-around balance of capacity, security, and durability. If budget is a concern, the SportRack Vista XL provides good value without sacrificing essential features. For those in need of a premium, high-security option, the Yakima SkyBox NX XXL delivers advanced lock systems and robust construction. Beginners or infrequent users might prefer models with straightforward installation and lighter weight, while frequent travelers should prioritize larger capacities and dual-side opening features. Ultimately, matching your specific needs with these features will ensure a satisfying purchase.
