More Details on Our Top Picks
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier, 61″ L x 27.6″ W x 13.8″ H, Dual-Side Opening, for SUV/Car/Van, Black
This cargo box stands out for offering a generous 13.4 cubic feet of storage with a durable, waterproof ABS shell, making it versatile for various vehicles including SUVs and vans. Its dual-side opening simplifies access, especially when parked in tight spaces, and the locking system adds security for valuable belongings. Compared with the Thule Motion 3, it provides slightly less aerodynamic design but compensates with easier installation due to its straightforward compatibility with most crossbars. A key tradeoff is its weight—at 24.25 lbs, it may be heavier than some users prefer, and installation can be constrained by crossbar width. Still, for those seeking a reliable, weatherproof cargo solution without premium pricing, this model offers a solid mix of capacity and security.
Pros:- Large 13.4 cu.ft. capacity for extended trips
- Dual-side opening for convenient access from either side
- Secure locking system with keys enhances security
- Weatherproof ABS construction resists elements
Cons:- Requires peeling protective film before use, adding prep time
- Installation may be limited by crossbar width, complicating setup
Best for: Families needing reliable, weather-resistant storage for road trips with moderate installation expertise
Not ideal for: Users with very narrow crossbars or seeking ultralight, minimalist carriers for quick trips
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Weight:24.25 lbs
- Max Load Capacity:150 lbs
- Material:ABS
- Locking System:Yes, with keys
- Compatible Cross Bar Width:up to 2.36″
Our verdict“This is an excellent choice for those wanting a large, secure, and weatherproof cargo box with straightforward installation for family adventures.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 is favored for its sleek, aerodynamic profile that reduces drag and boosts fuel efficiency during long drives. Its robust construction and quick-mount system make installation easier for experienced users, and the secure locking mechanism offers peace of mind. Unlike the TUFFIOM model, it doesn’t specify internal volume or weight capacity, but its high-quality build and limited lifetime warranty make it a strong premium pick. The main tradeoff is the higher price point, which may be less appealing for budget-conscious buyers. This model appeals to those prioritizing style, efficiency, and long-term durability over maximum capacity or simplicity.
Pros:- Aerodynamic design reduces drag and enhances fuel efficiency
- Easy to mount with a quick-mount system and torque indicator
- Secure locking system for added security
- Limited lifetime warranty for peace of mind
Cons:- No specified internal volume or weight capacity details
- Some users report challenges during installation
Best for: Adventure enthusiasts wanting an aerodynamic, durable carrier that optimizes fuel economy during frequent trips
Not ideal for: Budget shoppers or users seeking a larger capacity or soft-shell flexibility
- Brand:Thule
- Model Number:197074566126
- Item Dimensions:81″L x 38″W x 18″H
- Warranty:Limited Lifetime
Our verdict“Ideal for those valuing sleek design, ease of mounting, and durability over the largest capacity or lowest cost.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This universal cargo box offers 11 cubic feet of storage, making it suitable for vehicles with cross bars looking for a weather-resistant solution. Made from durable ABS plastic, it provides a secure lock and simple, tool-free installation—features that match the basic expectations of budget-friendly options like the TUFFIOM. However, with a capacity slightly lower than the TUFFIOM and limited color choices, it’s better suited for shorter trips or lighter loads. Its universal mounting system ensures moderate versatility, but it’s not compatible with vehicles without cross bars, which limits its appeal for some buyers. Nonetheless, it delivers solid value for casual users prioritizing weather resistance and ease of setup.
Pros:- Weather-resistant ABS plastic ensures protection against elements
- Easy to install without tools
- Secure locking system for peace of mind
- Decent capacity for short to medium trips
Cons:- Limited to vehicles with cross bars, restricting compatibility
- Opening may be difficult in cold weather
Best for: Budget-conscious travelers with vehicles equipped with cross bars seeking weatherproof, straightforward storage
Not ideal for: Owners of vehicles without cross bars or those needing larger capacity for extended trips
- Material:ABS plastic
- Capacity:11 cubic feet
- Dimensions:53 x 34 x 15 inches
- Weight Capacity:110 lbs
- Color:Black
Our verdict“A practical, affordable choice for casual travelers who need weatherproof protection and simple installation.”
Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA
This heavy-duty carrier boasts 18 cubic feet of weatherproof storage, making it ideal for full-family camping trips or long road journeys. Its HDPE shell provides superior durability against impacts and weather, outperforming softer or less robust options like the PVC-based MIDABAO. The dual side locking system with keys enhances security, and its large size ensures ample space. Compared to the TUFFIOM, it offers more capacity but may be heavier to install and handle for some users. The 30-day limited warranty may be a concern for those seeking longer-term protection, but overall, this model excels in rugged outdoor scenarios where durability and high capacity are priorities.
Pros:- Durable, weatherproof HDPE shell withstands impacts
- Large 18 cu ft capacity for extensive gear storage
- Secure dual side locking with keys enhances security
- Made in the USA for quality assurance
Cons:- Limited 30-day warranty may not cover long-term durability concerns
Best for: Outdoor enthusiasts needing a rugged, high-capacity carrier for extended camping and road trips
Not ideal for: Casual users or those with limited strength for handling heavier cargo boxes
- Capacity:18 Cu Ft
- Material:HDPE Plastic
- Dimensions:57 L x 38.5 W x 17.75 H inches
- Locking System:Dual Side Locking with Keys
- Weatherproof:Yes
- Made in:USA
Our verdict“Best suited for outdoor adventurers who need a tough, sizeable cargo box capable of handling rough conditions and heavy loads.”
MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks Option
The MIDABAO roof bag offers a spacious 20 cubic feet of cargo capacity, making it the largest soft-shell option in this lineup and a good complement to the hard-shell choices like the TUFFIOM or Thule. Its PVC material is waterproof, and the flexible design allows for easy storage when not in use. Unlike rigid carriers, it can be fitted to vehicles without cross bars, offering greater adaptability—ideal for those with rackless cars or seeking quick setup. However, it sacrifices some durability compared to hard shells, and proper installation is crucial to prevent shifting during travel. For drivers prioritizing maximum capacity and adaptability over hard-shell protection, this bag provides a flexible, waterproof solution.
Pros:- Largest capacity at 20 cubic feet for maximum storage
- Waterproof PVC material protects contents from rain and splashes
- Flexible, easy to mount on various vehicle types, including without racks
- Includes anti-slip mat and multiple straps for secure fit
Cons:- Less durable than rigid, hard-shell carriers
- Requires correct installation to prevent shifting or damage
Best for: Travelers with rackless vehicles needing maximum cargo capacity and easy stowage
Not ideal for: Users requiring the highest level of impact resistance or planning to carry very heavy loads frequently
- Capacity:20 cubic feet
- Material:PVC
- Dimensions:51.1” x 39” x 17”
- Includes:Anti slip mat, mounting straps
- Straps:6 wide straps, 2 3M straps
Our verdict“Best suited for those needing maximum cargo space on rackless or rack-equipped vehicles with quick, flexible setup requirements.”
Garvee Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
The Garvee Rooftop Cargo Box stands out for its durability and ease of access, thanks to dual-sided opening. Compared with larger options like the SportRack Vista XL, it offers a more compact 12 cubic feet, which may be limiting for bigger families but is ideal for those needing a reliable, weather-resistant carrier without excess bulk. Its universal fit and included security features make it a practical choice for casual road trips. The main tradeoff is its size—adequate for moderate luggage but not for large-scale gear or extensive family gear. Durable ABS plastic construction ensures weather resistance, while the 12 cubic feet capacity balances space and manageability. The dual access enhances convenience, but verification of roof rack compatibility is recommended to avoid installation issues.
Pros:- Durable, weather-resistant ABS plastic shell
- Easy dual-sided access for quick loading and unloading
- Universal fit for most roof rack systems
- Includes security features like keys and straps
Cons:- Limited to 12 cubic feet, which may be insufficient for bulky gear
- May require roof rack compatibility verification
Best for: Budget-conscious travelers needing a reliable, weatherproof carrier for moderate luggage on standard roof racks.
Not ideal for: Large families or heavy-duty users requiring more than 12 cubic feet of storage capacity.
- Material:ABS plastic
- Capacity:12 cubic feet (340L)
- Dimensions:54.3″L x 31.5″W x 13.4″H
- Max Load:165 lbs

Our verdict“A solid choice for budget-minded users seeking a durable, weatherproof roof box with convenient access, suitable for moderate luggage needs.”
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 ideal for families or groups needing ample space for skis, luggage, and gear. Its tool-free installation with torque indicator simplifies setup, especially compared to the more manual installation of the SportRack Vista XL. While specific dimensions are not provided, its durable ASA-ABS construction ensures weather resistance and longevity. The dual-side access is convenient, but the absence of detailed weight specifications might leave some users unsure about load limits. Compared to larger cargo boxes, the Thule Pulse 2 M strikes a balance between capacity and ease of use, making it a smart choice for frequent travelers who value quick setup and secure fit.
Pros:- Large 14 cubic feet capacity for versatile gear storage
- Easy, tool-free installation with torque indicator
- Weather-resistant durable shell
- Dual-side access for easy loading
Cons:- Lack of specific dimensions limits precise fit assessment
- Weight of the cargo box not specified, which could impact vehicle handling

Not ideal for: Owners of small vehicles with limited roof space or those seeking detailed dimension info for precise fitting.
- Capacity:14 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Dimensions:Not specified
- Model Number:610250
- Brand:Thule
Our verdict“Ideal for frequent travelers wanting a spacious, secure, and easy-to-install roof box without complex setup steps.”
SportRack Vista XL Rear Opening Cargo Box, Black
The SportRack Vista XL delivers a substantial 18 cubic feet of storage, making it suitable for large families or extensive gear. Its rear-opening design provides convenient access from traffic side, which is especially useful in tight parking situations. Constructed from durable UV-resistant ABS, it offers excellent weather resistance. However, its maximum weight limit of 100 pounds can restrict heavier loads, and the rear opening might be less accessible from the passenger side in some vehicles. Compared with the Garvee model, it provides more space but at a slightly higher profile and weight. It’s best suited for users prioritizing volume over quick, multi-directional access.
Pros:- Extensive 18 cubic feet capacity for large gear
- Durable UV-resistant ABS construction
- Easy tool-free mounting and removal
- Includes lock for security
Cons:- Limited to 100 pounds load capacity, restricting heavy items
- Rear-opening may be less accessible from traffic side
Best for: Families or groups needing maximum storage capacity for long trips and large gear loads, especially where rear access is convenient.
Not ideal for: Urban drivers with tight parking or vehicles with limited rear clearance, due to the rear-opening design and size.
- Capacity:18 cubic feet (510 L)
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Min-Max Crossbars Spacing:23 5/8 – 29 3/4 inches
- Max Weight Capacity:100 pounds (45 kg)
- Mounting Hardware:Tool-free
Our verdict“Best suited for those who need maximum capacity and are okay with rear access constraints for large gear loads.”
Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cu Ft, Fits Cars with/Without Rack
The Sailnovo Roof Bag offers an impressive 20 cubic feet of soft, waterproof storage, making it ideal for travelers seeking maximum flexibility. Its tear-resistant 1000D Oxford fabric and included straps ensure durability and security across various vehicle types, including those without roof racks. Unlike rigid boxes like the Garvee, this soft carrier can adapt to different roof shapes and sizes, but overhanging or improper filling can lead to water pooling or instability. Its foldable design allows for easy storage when not in use, but it’s less suitable for very small cars or vehicles with sunroofs where overhang might be problematic. This option excels in versatility and capacity for adventurous trips.
Pros:- Large 20 cubic feet capacity for multiple items
- Waterproof and tear-resistant construction
- Flexible fit for various roof types and sizes
- Foldable for compact storage
Cons:- Installation may be slightly complex for some users
- Overhanging could be an issue on very small vehicles

- Material:1000D Oxford cloth
- Includes:6 tie-down straps, 6 door hooks, storage bag, manual

Our verdict“A flexible, high-capacity soft roof bag perfect for camping and road trips where adaptability matters most.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier combines substantial capacity with rugged waterproofing, making it an excellent choice for extended road trips and outdoor adventures. Constructed from 840D PVC, it withstands harsh weather while providing ample space for multiple suitcases, tents, and gear. Its reinforced straps and included travel kit simplify installation across various vehicle types, including those without roof racks. While some users may find the installation process slightly involved, the large capacity and heavy-duty build justify the effort. Compared to the Sailnovo, it emphasizes durability and long-term reliability, especially in wet conditions. It is best suited for travelers who prioritize security, waterproofing, and capacity for extended journeys.
Pros:- Heavy-duty waterproof construction with 840D PVC
- Large 21 cubic feet capacity for extensive gear

Our verdict“Best for serious outdoor travelers requiring maximum waterproof protection and capacity for long, gear-heavy trips.”
DNA MOTORING Rooftop Cargo Box Carrier, 11 Cubic Feet, 53″ L x 34″ W x 15″ H, Lockable, Black
This option stands out for offering a generous 11 cubic feet of storage at a very accessible price point, making it a solid choice for those who want extra space without breaking the bank. Compared with the larger Thule Pulse 2 L, the DNA MOTORING provides slightly less capacity but at a fraction of the cost. Its impact-resistant ABS construction ensures durability against weather, and the lockable lid adds a layer of security. However, it only fits vehicles equipped with cross bars, and its 110 lbs load limit may restrict heavier gear. The installation is straightforward but lacks detailed instructions, which might pose a challenge for first-time users. This cargo box is ideal for budget-conscious families seeking reliable extra storage for moderate loads on vehicles with cross bars.
Pros:- Affordable price point with decent capacity
- Durable impact-resistant ABS material
- Secure lockable lid with key
Cons:- Fits only vehicles with cross bars, limiting compatibility
- No detailed instructions for installation
- Limited to 110 lbs maximum load, restricting heavier items
Best for: Budget-conscious families needing reliable extra cargo space for vehicles with cross bars
Not ideal for: Owners of vehicles without cross bars or those requiring very high load capacity
- Capacity:11 cubic feet
- Max Load:110 lbs
- Dimensions:53″ L x 34″ W x 15″ H
- Material:Impact-resistant ABS
- Finish:Black textured
- Opening:Side opening, stays open until closed
Our verdict“A cost-effective choice for vehicle owners with cross bars who need moderate extra storage space.”
Garvee Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
This model makes the most sense for travelers prioritizing weather protection, with 14 cubic feet of storage wrapped in durable ABS that resists water and UV rays. Its dual-sided opening allows quick access from either side, a feature that outshines the single-opening GarveeTech in convenience. It fits most roof racks, but verification is needed to ensure compatibility. Compared to the smaller DNA MOTORING box, it offers more capacity, yet it is potentially heavier and may be more cumbersome to install. The inclusion of security features like keys and straps adds peace of mind during stops. This cargo box suits those who value weatherproofing and security for longer trips with larger luggage loads.
Pros:- Waterproof and UV-resistant construction
- Generous 14 cubic feet capacity
- Dual-sided opening for easy access
- Includes security features like keys and straps
Cons:- Requires roof rack compatibility verification

- Max Load:165 lbs
- Opening:Dual-sided
- Compatibility:Most roof racks
Our verdict“Ideal for travelers needing weatherproof, secure storage for sizable luggage loads on roof racks.”
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft
The Thule Pulse 2 L leads with its impressive 16 cubic feet of capacity, making it the best option for those with extensive gear needs. Its modern, streamlined shape complements contemporary vehicles, and the tool-free installation with a torque indicator simplifies setup. Compared to the Garvee models, it offers a larger volume but is bulkier, which could be a concern for smaller cars. Its ASA-ABS plastic ensures weather resistance, although its size might limit compatibility with some compact vehicles. The dual-side opening allows quick access, and the durable construction promises long-term use. This pick makes the most sense for outdoor enthusiasts and families with high-volume luggage, willing to accommodate a slightly larger, more conspicuous cargo box.
Pros:- Largest capacity at 16 cubic feet
- Easy tool-free installation with torque indicator
- Weather-resistant ASA-ABS plastic
- Dual-side opening for convenience
Cons:- Bulky, may not suit small vehicles
- Requires roof-mounted installation only

- Capacity:16 Cubic Feet
- Load Capacity:75 kg

GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Roof Luggage Storage
This model makes a strong case for heavy-duty use with 12 cubic feet of space and a durable ABS build, suitable for road trips requiring robust protection. Its dual-sided opening facilitates quick access, similar to Garvee’s other offerings, but with added features like keys and straps for security. Compared to the smaller DNA MOTORING, it provides less capacity but emphasizes weather resistance and security. It fits vehicles with roof racks, but verification is necessary for compatibility, and its weight may pose handling challenges during installation. The one-year warranty is a minor drawback, but overall, it offers a balanced mix of durability and security. This cargo box appeals to travelers who need reliable, weatherproof storage with added security features for longer journeys.

- Compatibility:All vehicles with roof racks
Our verdict“Ideal for road trips requiring rugged, weatherproof, secure cargo storage in vehicles with roof racks.”
How We Picked
We evaluated each cargo box based on several key criteria: capacity, build quality, ease of installation and access, weather resistance, security features, and value for the price. Preference was given to models with durable, weatherproof materials and user-friendly features like dual-side opening. We also considered customer reviews and brand reputation to gauge reliability over time. The ranking reflects a balance between performance, versatility, and cost, aiming to recommend options suitable for a wide range of users—from casual travelers to frequent road trippers.Factors to Consider When Choosing Car Roof Cargo Box
Selecting the right car roof cargo box involves more than just capacity. Understanding the key factors can help you avoid common pitfalls, such as overpaying for features you don’t need or choosing a size incompatible with your vehicle. Here are the most important considerations:Capacity and Size
Capacity directly impacts how much gear you can carry, but larger boxes also add weight and can affect your vehicle’s aerodynamics. Measure your roof’s dimensions and compare them with the cargo box’s specifications to ensure a proper fit. Remember, a box that’s too big for your vehicle can be difficult to mount and may compromise handling. Conversely, choosing a too-small box might leave you short on space, prompting additional trips or purchases.
Materials and Weather Resistance
Hard-shell cargo boxes typically offer superior protection against weather and theft, thanks to durable plastics and lockable mechanisms. Soft roof bags are lighter and easier to store when not in use but tend to be less waterproof and more susceptible to damage. Consider your climate—if you often travel in rain or snow, investing in a fully waterproof, rugged hard-shell model is advisable. Cheaper materials may crack or warp over time, reducing their protective qualities.
Ease of Use and Accessibility
Look for features like dual-side opening, which simplifies access to your gear from either side of the vehicle. Ease of installation is also critical—models with straightforward mounting systems save time and reduce frustration. Consider how often you’ll need to remove or install the box; quick-release systems or lightweight designs can make this process more manageable. Also, check if the box comes with clear instructions and compatible mounting hardware.
Aerodynamics and Noise
Some cargo boxes are designed to be more aerodynamic, reducing wind resistance and noise during drives. This is especially important for frequent travelers who want a quieter, more fuel-efficient ride. Cheaper, boxy designs tend to create more drag and wind noise, which can detract from driving comfort. If you plan to use your box regularly, investing in a streamlined model often pays off over time.
Security and Locking Features
Since cargo boxes hold valuable gear, locking mechanisms are vital for theft prevention. Look for models with reliable, lockable lids that are resistant to tampering. Some models also feature reinforced mounting points for added security. Keep in mind that more sophisticated locks might slightly increase the price, but they provide peace of mind during stops or overnight stays. Basic locks may suffice if your vehicle is parked in a secure location.
Frequently Asked Questions
Will a roof cargo box fit on my vehicle’s roof rack?
Most cargo boxes are designed to fit on standard roof racks, but compatibility depends on your vehicle’s roof type and the rack’s dimensions. It’s essential to measure your roof’s width and check the cargo box’s mounting specifications. Many models include adjustable mounting systems that accommodate a range of rack sizes. If your rack is narrower than the box’s mounting base, you might need additional adapters, so verifying compatibility before purchase is wise.
How much does a roof cargo box typically affect my vehicle’s fuel efficiency?
Adding a roof cargo box increases aerodynamic drag, which can reduce fuel economy by approximately 5-15%, especially at highway speeds. The impact varies depending on the size and shape of the box—as more aerodynamic designs tend to cause less resistance. If fuel efficiency is a priority, consider a sleek, hard-shell model with a low profile. Removing the box when not in use can also help save fuel over long trips.
Are soft roof bags as secure as hard-shell cargo boxes?
Soft roof bags generally provide less security because they are easier to cut open and lack robust locking mechanisms. They are more vulnerable to theft and weather damage, especially in heavy rain or snow. However, soft bags are lighter, easier to store, and often less expensive, making them suitable for infrequent use or short trips. For frequent travelers or those carrying valuable gear, a hard-shell box offers significantly better security and protection.
What’s the best way to maintain and clean my roof cargo box?
Regular cleaning with mild soap and water is usually sufficient to keep your cargo box in good condition. Avoid harsh chemicals that can degrade the material. For hard-shell models, check the locking mechanisms and hinges periodically, lubricating them with appropriate products if needed. When not in use, store the box in a dry, sheltered place to prevent UV damage and warping. Proper maintenance extends the lifespan and keeps your cargo box looking and functioning like new.
How do I choose the right capacity for my travel needs?
Assess how much gear you typically carry and plan for potential additional items in the future. For occasional trips with minimal gear, a smaller box around 11-14 cubic feet may suffice. For larger families or frequent travelers with bulky equipment, opting for 20 cubic feet or more provides extra space without sacrificing convenience. Always consider the vehicle’s roof load limit to avoid overloading, which can impact safety and handling.
