Key Takeaways

  • Higher capacity cargo boxes tend to be heavier and more challenging to install, but provide more space for long trips.
  • Hard-shell models generally offer better security and durability compared to soft-sided cargo bags, though they come at a higher price.
  • Dual-side opening designs improve access, especially on taller vehicles or limited parking spaces, but often add to the cost.
  • Aerodynamic shapes can reduce wind noise and drag, saving fuel on long drives, making them ideal for frequent travelers.
  • Price varies widely—investing in a premium model often means better materials and security, but less expensive options can suffice for occasional use.

More Details on Our Top Picks

  1. Mockins 64″x39″x6″ Extendable Heavy Duty Roof Rack Basket & 16 Cu Ft Waterproof Cargo Bag for Top of Car

    Mockins 64"x39"x6" Extendable Heavy Duty Roof Rack Basket & 16 Cu Ft Waterproof Cargo Bag for Top of Car

    Best Overall for Versatile Heavy-Duty Storage

    View on Amazon

    This combo set from Mockins stands out for its robust construction and flexible design. The extendable basket allows for a significant increase in cargo capacity, making it ideal for long trips with bulky gear, unlike the more rigid Thule Motion 3, which offers a sleek but less expandable option. While the basket’s steel frame supports up to 250 lbs, the assembly process can be challenging, and its weight may be difficult for solo handling. The waterproof cargo bag adds weather resistance, but its weight and limited detailed specs could pose issues for some users. This set is perfect for those who prioritize heavy-duty capacity and comprehensive security features. Tradeoffs include heavier weight and more complex setup compared to simpler soft-shell options.

    Pros:
    • Durable, weatherproof steel construction supports heavy loads
    • Extendable basket maximizes cargo space when needed
    • Complete set with straps, net, and lock for secure transport
    Cons:
    • Assembly may require effort and tools
    • Heavy weight could be difficult to handle alone
    • Limited weight details for cargo bag affect precise planning

    Best for: SUV owners needing durable, expandable cargo solutions for long-distance travel or heavy gear.

    Not ideal for: Casual drivers with limited cargo needs or those seeking lightweight, quick-install options.

    • Dimensions:64″x39″x6″ (extendable from 43″ to 64″ )
    • Capacity:250 lbs
    • Cargo Volume:16 Cu Ft
    • Material:Steel (basket), Vinyl (cargo bag)
    • Includes:Roof basket, waterproof cargo bag, buckle straps, ratchet straps, cargo net, lock
    Our verdict
    “This set is best suited for users who need heavy-duty, expandable cargo capacity with comprehensive security features.”
  2. Mockins 45 Cu Ft XL Waterproof Rooftop Cargo Bag 75″x48″x22″

    Mockins 45 Cu Ft XL Waterproof Rooftop Cargo Bag 75"x48"x22"

    Best for Large Volume with All-Weather Protection

    View on Amazon

    The Mockins XL Roof Cargo Bag offers an impressive 45 cubic feet of waterproof storage, making it ideal for large families or those needing to carry bulky items without roof racks. Its soft vinyl shell provides weather resistance comparable to the iBirdie Roof Rack Cargo Carrier, but with a focus on high-volume capacity. While its large size and included straps allow for straightforward installation, some users report challenges in securing it tightly, especially on irregular surfaces. Compared to the more aerodynamic Thule Motion 3, this bag sacrifices some ease of use for maximum capacity and flexibility. This product is a smart choice for travelers prioritizing volume and weatherproofing over sleekness or ease of mounting. Tradeoffs include bulkiness when stored and potential installation challenges.

    Pros:
    • Very large 45 cu ft capacity for bulky gear
    • Weatherproof and rugged vinyl construction
    • Includes straps, hooks, lock, and storage case
    Cons:
    • Bulky for storage when not in use
    • Designed mainly for vehicles without roof racks, limiting compatibility
    • Some users find installation tricky

    Best for: Families or campers needing high-capacity, waterproof storage for vehicles without roof racks.

    Not ideal for: Drivers seeking a sleek, aerodynamic roof box or those with limited storage space for bulky items.

    • Capacity:45 cubic feet
    • Dimensions:75″x48″x22″
    • Material:Soft-shell vinyl
    • Includes:Car roof mat, storage bag, lock, straps, hooks, case
    • Warranty:10 years
    Our verdict
    “This cargo bag suits those needing maximum volume and weather protection, especially on unrackable vehicles.”
  3. GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12 Cubic Feet, Black

    GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12 Cubic Feet, Black

    Best for Easy Access and Compatibility

    View on Amazon

    Compared with larger soft-shell options like the iBirdie Roof Rack Cargo Carrier, the GarveeTech box offers a more aerodynamic form and dual-sided access, making loading and unloading more convenient. Its ABS plastic shell provides solid waterproofing and UV resistance, but the one-year warranty is shorter than some competitors, and installation may require vehicle-specific verification. The 12 cubic feet capacity makes it suitable for moderate gear needs, but not for large-volume trips. Its universal roof rack compatibility broadens appeal, unlike the Mockins 64″ basket, which requires custom mounting. This box is ideal for users who value quick access and a sleek profile but are willing to accept a limited capacity and shorter warranty period. Tradeoffs include slightly less volume and warranty coverage compared to premium models.

    Pros:
    • Durable waterproof ABS shell resists UV and weather
    • Dual-side opening for easy access
    • Universal fit with roof racks
    Cons:
    • Limited 1-year warranty
    • Capacity may be insufficient for large loads
    • Some installation concerns reported

    Best for: Owners of roof rack-equipped vehicles seeking easy access and weatherproofing for moderate loads.

    Not ideal for: Heavy-duty users or those carrying very bulky gear regularly, due to its limited capacity and warranty.

    • Material:ABS plastic
    • Capacity:12 cubic feet
    • Dimensions:54.3″L x 31.5″W x 13.4″H
    • Weight Capacity:165 lbs
    • Includes:Security straps, keys
    • Warranty:1 year
    Our verdict
    “This cargo box is perfect for vehicle owners who prioritize convenient access and a sleek profile for moderate gear loads.”
  4. Thule Motion 3 Rooftop Box

    Thule Motion 3 Rooftop Box

    Best for Aerodynamic, Stylish Travel

    View on Amazon

    The Thule Motion 3 combines style and function with its sleek, aerodynamic design that reduces drag, helping improve fuel efficiency during long drives. Its spacious interior and quick-mount system make installation straightforward, especially compared to bulkier soft-shell options like the iBirdie Roof Rack Cargo Carrier. However, the lack of specific pricing details means potential buyers need to verify affordability, and some reviews mention installation difficulties, which could deter less experienced users. The limited lifetime warranty offers peace of mind, but the box’s size—81″L x 38″W x 18″H—may be less suitable for small vehicles or tight parking spaces. This pick is ideal for style-conscious travelers who want a reliable, aerodynamic carrier with easy mounting. Tradeoffs include higher price and installation complexity versus sleek design and long-term durability.

    Pros:
    • Aerodynamic shape reduces drag and fuel costs
    • Quick-mount system simplifies installation
    • Secure locking ensures safety during transit
    Cons:
    • Price not specified; may be costly
    • Installation can be challenging for some users
    • Size may not fit all vehicle types

    Best for: Travelers seeking an aerodynamic, stylish cargo box for frequent outdoor trips.

    Not ideal for: Budget-conscious buyers or those with small vehicles needing a compact roof box.

    • Brand:Thule
    • Model Number:197074566126
    • Dimensions:81″L x 38″W x 18″H
    • Included Components:Rooftop cargo carrier
    • Warranty:Limited Lifetime
    Our verdict
    “This rooftop box is perfect for style-focused users who prioritize efficiency and secure locking during frequent travels.”
  5. iBirdie Roof Rack Cargo Carrier 36.4 Cubic Feet

    iBirdie Roof Rack Cargo Carrier 36.4 Cubic Feet

    Best for Universal, Heavy-Duty Storage

    View on Amazon

    The iBirdie Roof Rack Cargo Carrier offers a substantial 36.4 cubic feet of waterproof storage, making it an excellent choice for varied vehicle types. Its universal fit and quick installation process appeal to a broad audience, unlike more vehicle-specific options like the GarveeTech box. The reinforced buckles and anti-slip mats enhance stability during travel, but some reviews raise concerns about long-term durability and the need for additional straps on certain vehicles. Its heavy load capacity makes it suitable for large trips, yet the weight when fully loaded can be a drawback for some users. This carrier is ideal for those seeking high volume and straightforward installation, accepting some tradeoffs in durability over time. Tradeoffs include potential durability concerns and the need for extra straps for certain setups.

    Pros:
    • Waterproof, heavy-duty construction withstands weather
    • Large 36.4 cu ft capacity for bulky gear
    • Quick and easy installation with anti-slip mats
    Cons:
    • Some reviews mention durability issues over time
    • May require additional straps for certain vehicles
    • Heavy when fully loaded, affecting handling

    Best for: Vehicle owners needing large, waterproof storage with quick, universal mounting.

    Not ideal for: Users concerned about long-term durability or those with very small or lightweight vehicles.

    • Material:1200D oxford and PVC
    • Capacity:36.4 cubic feet
    • Dimensions:56 x 45 x 25 inches
    • Includes:Anti-slip mat, 6 hooks
    • Warranty:1 year
    Our verdict
    “This cargo carrier is best suited for users needing large, waterproof storage that fits a variety of vehicles with quick setup.”
  6. Mockins 40 CuFt XXL Roof Bag Cargo Carrier for Top of Vehicle

    Mockins 40 CuFt XXL Roof Bag Cargo Carrier for Top of Vehicle

    Best for Large, Flexible Storage on a Budget

    View on Amazon

    The Mockins XXL Roof Bag stands out for its massive 40 cubic feet of waterproof space, making it an excellent choice for those needing to pack bulky gear or multiple bags. Compared to the Thule Pulse 2 M, it offers more capacity but relies on flexible vinyl instead of hard shells, which can be less secure in high winds or rough weather. Its multiple attachment points and included accessories make setup versatile, though it requires careful installation to prevent shifting during transit. The heavy-duty vinyl material provides durability and waterproofing, but some users find it stiff and less easy to fold or store when not in use. Overall, this bag suits travelers prioritizing capacity and affordability over sleekness or ease of handling.

    Pros:
    • Enormous 40 cubic feet capacity for flexible packing
    • Fully waterproof and abrasion-resistant for all-weather use
    • Multiple secure attachment options for versatile installation
    • Includes comprehensive accessories and a durable carry bag
    Cons:
    • Customer ratings are below 4 stars, indicating mixed reviews on durability
    • Heavy and stiff material can be cumbersome to handle or store
    • May require meticulous setup to prevent shifting or loosening during travel

    Best for: Families or groups needing high-volume, waterproof cargo for extended trips or camping gear

    Not ideal for: Urban commuters or drivers seeking a sleek, aerodynamic look with minimal fuss

    • Dimensions:72″x48″x20″
    • Capacity:40 cubic feet
    • Material:Waterproof vinyl
    • Warranty:10-year limited warranty
    • Included Components:Buckle straps, ratchet straps, door hooks, trunk hooks, roof mat, carry bag, lock
    Our verdict
    “This roof bag is ideal for those needing maximum capacity and waterproof protection, accepting some handling effort and durability tradeoffs.”
  7. SportRack Vista XL Rear Opening Cargo Box, Black

    SportRack Vista XL Rear Opening Cargo Box, Black

    Best for Easy Access and Moderate Capacity

    View on Amazon

    The SportRack Vista XL is designed for straightforward access with its rear-opening hatch, making it a practical choice for frequent stops or quick loading. Compared with the Thule Force XT XL, it offers less sleekness but excels in ease of access, especially if you prefer loading from the back rather than the top. Its 18 cubic feet of UV-resistant ABS provides durability against sun damage, though its weight can be demanding for some users during installation or removal. The tool-free mounting system simplifies setup, but compatibility depends on your roof rack dimensions, so checking fit is essential. Locking adds security, but keys can be misplaced, and the weight might be a concern for those with limited strength or mobility. This box is well-suited for users who prioritize quick access over maximum capacity.

    Pros:
    • Large 18 cubic foot storage capacity for versatile gear
    • UV-resistant ABS shell resists sun degradation
    • Rear opening for effortless access and loading
    • Tool-free mounting system simplifies installation
    Cons:
    • Can be heavy to handle, especially when full
    • Compatibility with roof racks varies, requiring careful measurement
    • Locking mechanism may require key management and can be a hassle

    Best for: Active families who want quick, easy access to gear without sacrificing durability

    Not ideal for: Solo travelers or those with small or incompatible roof racks who need a lightweight option

    • Capacity:18 cubic feet (510 L)
    • Material:UV-resistant ABS
    • Dimensions:63 x 38 x 19 in
    • Min-Max Crossbars Spacing:23 5/8 – 29 3/4 in
    • Max Weight Capacity:100 pounds
    Our verdict
    “This cargo box offers convenient rear access and solid durability, ideal for users valuing quick loading and unloading over extreme capacity.”
  8. Thule Force XT XL Roof Cargo Box

    Thule Force XT XL Roof Cargo Box

    Best for Sleek, Reliable Daily Use

    View on Amazon

    The Thule Force XT XL combines durability with a refined design, making it suitable for daily drivers and active lifestyles. Its quick, secure mounting system with safety indicators ensures peace of mind during installation, while dual-side access simplifies loading and unloading. Compared to the RoofRack Rooftop Carrier Basket, the Thule offers a more aerodynamic shape, reducing wind resistance and noise on the road. Extensively tested for safety and reliability, it is a dependable choice for regular use. However, its higher price point and limited customer review details might give some pause, especially for budget-conscious buyers. This model makes the most sense for drivers seeking a sleek, well-tested solution that pairs easily with daily driving routines.

    Pros:
    • Durable, sleek design suitable for everyday use
    • Quick, tool-free mounting with safety indicators
    • Dual-side access for convenience
    • Extensively tested for safety and reliability
    Cons:
    • Price may be higher than some budget options
    • Limited detailed customer reviews available
    • Size may not fit all vehicle roof types without checking fit

    Best for: Commuters or weekend travelers needing a secure, easy-to-use cargo box with a sleek appearance

    Not ideal for: Those prioritizing maximum capacity or off-road ruggedness over style and daily reliability

    • Brand:Thule
    • Model Number:645850
    • Item Type:Rooftop Cargo Box
    • Unit Count:1
    • UPC:197074660039

  9. Roof Rack Rooftop Cargo Carrier Basket 65″ x 39″ x 6″ with Waterproof Bag 20 Cu.Ft.

    Roof Rack Rooftop Cargo Carrier Basket 65" x 39" x 6" with Waterproof Bag 20 Cu.Ft.

    Best for Heavy Loads and Rugged Durability

    View on Amazon

    The Roof Rack Rooftop Cargo Carrier Basket offers a robust steel construction with a 200-pound weight limit, making it suitable for heavy or bulky cargo. Its aerodynamic design with a wind shield helps reduce drag, and the included waterproof bag along with straps and a lock enhance security and weather resistance. Compared with the Mockins waterproof bag, this carrier provides a more structured platform for heavy-duty hauling, but the basket’s bulk can make vehicle handling more affected, especially at higher speeds. Assembly requires some effort, and compatibility depends on your vehicle’s cross bar spacing. This product is best for off-road enthusiasts or users needing to carry heavy, irregularly shaped loads while maintaining weatherproof protection.

    Pros:
    • Heavy-duty tubular steel construction with 200 lbs capacity
    • Aerodynamic design reduces wind resistance
    • Includes waterproof bag, cargo net, straps, and lock for security
    • Rated for demanding loads and rugged conditions
    Cons:
    • Assembly can be time-consuming and physically demanding
    • Bulkier footprint may impact vehicle handling and fuel efficiency
    • Compatibility depends on vehicle cross bars, requiring measurement

    Best for: Adventurers or off-road users needing rugged, heavy-duty cargo capacity

    Not ideal for: Urban drivers or those with limited cross bar space seeking a lightweight or sleek solution

    • Material:Tubular steel with epoxy powder coating
    • Dimensions:65″ x 39″ x 6″
    • Capacity:200 lbs
    • Waterproof Bag Volume:20 Cu.Ft.
    • Included Components:Cargo net, ratchet straps, lock
    Our verdict
    “This cargo basket excels in heavy-duty, rugged applications where durability and weatherproofing are priorities, with some compromise on handling and ease of setup.”
  10. Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Feet

    Thule Pulse 2 M Roof-Mounted Cargo Box, 14 Cubic Feet

    Best for Compact, Reliable, Daily Use

    View on Amazon

    The Thule Pulse 2 M offers a compact 14 cubic feet of storage, making it a versatile choice for everyday trips, skis, or snowboards. Its ASA-ABS plastic shell provides weather resistance and durability, while the quick, tool-free mounting system with a torque indicator simplifies installation, especially for frequent use. Compared with the larger Thule Force XT XL, this model is more suited for smaller vehicles or those with limited roof space, providing a balance between capacity and ease of handling. Its dual-side opening enhances convenience, although the smaller capacity means it may not meet the needs of large families or extensive gear. This model fits best with drivers who need a dependable, smaller cargo solution for regular use.

    Pros:
    • Compact size with 14 cubic feet of storage
    • Easy, tool-free installation with torque indicator
    • Weather-resistant ASA-ABS plastic shell
    • Dual-side opening for convenience
    Cons:
    • Limited capacity for very large or bulky loads
    • Size may not fit all vehicle roof types without checking fit
    • Additional accessories might be needed for specialized gear

    Best for: Urban dwellers or small vehicle owners needing a reliable, compact cargo solution for daily or weekend trips

    Not ideal for: Users requiring maximum storage capacity or hauling very bulky gear on infrequent trips

    • Capacity:14 Cubic Feet
    • Load Capacity:75 kg
    • Material:ASA-ABS plastic
    • Access:Dual-side opening
    Our verdict
    “This cargo box offers a dependable, space-efficient option for daily drivers and weekend enthusiasts needing reliable weather protection in a compact form.”
  11. RoofPax XXL 28 cu ft Car Rooftop Cargo Carrier Bag with Waterproof Design and Heavy Duty Tie Down Straps

    RoofPax XXL 28 cu ft Car Rooftop Cargo Carrier Bag with Waterproof Design and Heavy Duty Tie Down Straps

    Best Overall for Large Capacity and Versatility

    The RoofPax XXL stands out for its massive 28 cubic feet capacity, making it ideal for families with extensive gear or long trips. Unlike rigid boxes like the Thule Pulse 2, this soft-sided carrier offers flexibility in fitting various vehicle types, especially those without roof racks. Its waterproof fabric and secure mounting system provide peace of mind in bad weather, though proper installation is essential to prevent shifting during travel. While the heavy-duty straps and lock enhance security, they can be cumbersome to handle, especially for shorter trips or quick loading. Compared to rigid options, its bulkiness might be a drawback for smaller vehicles or storage. This carrier makes the most sense for those needing maximum capacity and adaptability, accepting the tradeoff of handling a heavier, less aerodynamic bag.

    Pros:
    • Exceptional 28 cu ft capacity for large or multiple travelers
    • Weatherproof fabric offers strong protection against rain and snow
    • Compatible with vehicles with or without roof racks
    Cons:
    • Heavy and bulky, making handling and installation more challenging
    • Proper installation crucial to ensure security on the road

    Best for: Families or groups needing extensive cargo space on large SUVs or vans and willing to handle heavier, flexible storage options.

    Not ideal for: Small cars or vehicles with limited roof space where bulky, soft-sided carriers could be difficult to install or store.

    • Capacity:28 cu ft
    • Material:Waterproof fabric
    • Includes:4 tie down straps, 4 hooks, lock, storage bag
    • Warranty:Lifetime on zippers, 5 years on fabric
    • UPC:197644076048
    • Model Number:MRP-BAG28
    Our verdict
    “This is a top choice for those who prioritize capacity and flexibility over ease of handling and compact storage.”
  12. Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft

    Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft

    Best for Easy Access and Durability

    View on Amazon

    The Thule Pulse 2 L offers a sleek, durable solution with 16 cubic feet of cargo space, making it perfect for active travelers carrying skis, snowboards, or luggage. Its dual-side opening gives an advantage over the Roof Cargo Box 14 Cubic Feet by allowing easier loading from either side, especially useful when parking is tight. Constructed from weather-resistant ASA-ABS plastic, it withstands harsh conditions better than softer alternatives. However, its weight can be a challenge during installation without help, and it requires roof rails for mounting—features that might exclude some vehicles. Limited color options could also be a downside for style-conscious buyers. Compared to larger capacity soft bags, this rigid box emphasizes durability and quick access, making it ideal for frequent travelers needing reliable, weather-resistant storage.

    Pros:
    • Durable ASA-ABS plastic resists weather and impact
    • Dual-side opening allows easy access from either side
    • Weather-resistant construction protects cargo in all conditions
    Cons:
    • Heavy to install without help, especially for single users
    • Limited color choices and styles

    Best for: Active individuals or families who need reliable, durable storage for skis and luggage with quick, easy access.

    Not ideal for: Owners of vehicles without roof rails or those seeking maximum cargo capacity, as it’s somewhat limited in size and mounting options.

    • Capacity:16 Cubic Feet
    • Load Capacity:75 kg
    • Material:ASA-ABS plastic
    • Color:Black
    • Opening:Dual-side
    • Mounting System:Tool-free with torque indicator
    Our verdict
    “This model is an excellent pick for frequent travelers prioritizing durability and convenient access over maximum volume.”
  13. Roof Cargo Box 14 Cubic Feet, Dual-Side Opening Roof Rack

    Roof Cargo Box 14 Cubic Feet, Dual-Side Opening Roof Rack

    Best for Easy, Quick Installation and Reliable Weather Resistance

    View on Amazon

    The Roof Cargo Box 14 Cubic Feet provides a solid balance of size and practicality. Its weather-resistant hard-shell design is comparable to the TuFFIOM 13.4 cu.ft. but offers a slightly larger capacity with 14 cubic feet. The dual-side opening feature enhances convenience, especially when access from only one side isn’t feasible. Quick, tool-free installation makes it appealing for users who frequently switch vehicles or need fast setup, although its weight can make handling without assistance a challenge. Its load capacity of 150 pounds comfortably accommodates most luggage and gear, but heavier loads might require careful distribution. Overall, this box suits those seeking straightforward, reliable cargo protection with easy mounting and access, though it might not be the best for very heavy or oversized loads.

    Pros:
    • Weather-resistant and durable construction
    • Large 14 cu ft storage capacity
    • Dual-side opening for convenient access
    Cons:
    • Heavy to handle without help, especially for solo installation
    • Limited color options and aesthetic choices

    Best for: Drivers needing a dependable, weatherproof cargo box with quick, tool-free installation and dual access.

    Not ideal for: Individuals with very heavy loads or those needing maximum capacity, as it maxes out at 14 cu ft and 150 lbs load limit.

    • Material:ABS and PMMA
    • Capacity:14 cubic feet
    • Weight Capacity:150 lbs
    • Dimensions:62.52″ L x 32.48″ W x 13.19″ H
    • Included Components:Securing straps, spare key
    Our verdict
    “This cargo box is well-suited for users wanting straightforward installation and weather protection in a manageable size.”
  14. 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

    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

    Best for Secure, Weatherproof Storage with Easy Dual-Side Access

    View on Amazon

    The TUFFIOM 13.4 cu.ft. cargo box offers a streamlined, secure option for smaller loads, combining weatherproof durability with simple dual-side access. Its locking system with keys adds an extra layer of security compared to non-locking models like the Brown Hard Shell Roof Cargo Carrier. Made from impact-resistant ABS, it handles harsh weather while maintaining a sleek profile that reduces noise and drag. However, installation requires compatible crossbars up to 2.36 inches wide, which may limit compatibility with some vehicles. The peeling protective film can be an annoyance to new users, and the limited capacity suits lighter loads rather than bulky or heavy gear. This pick focuses on security, weatherproofing, and ease of use for smaller, everyday loads.

    Pros:
    • Secure locking system with keys for valuables
    • Weatherproof ABS protects against elements
    • Dual-side opening facilitates easy loading and unloading
    Cons:
    • Requires specific crossbar widths for mounting
    • Limited capacity for very large or heavy loads

    Best for: Urban or suburban drivers needing reliable, secure, and weatherproof storage for everyday trips or light outdoor gear.

    Not ideal for: Owners of large SUVs or those requiring very high capacity, as its 13.4 cu ft limit may fall short for bulky or extensive gear.

    • Capacity:13.4 cubic feet
    • Dimensions:61″ L x 27.6″ W x 13.8″ H
    • Material:ABS plastic
    • Max Load Capacity:150 lbs
    • Locking System:Yes, with keys
    • Applicable Cross Bar Width:up to 2.36″
    Our verdict
    “This cargo box is a reliable choice for security-conscious users seeking weatherproof protection and straightforward access for smaller loads.”
  15. Brown Hard Shell Roof Cargo Carrier 14 Cubic Feet with Security Keys and Tool-Free Mounting

    Brown Hard Shell Roof Cargo Carrier 14 Cubic Feet with Security Keys and Tool-Free Mounting

    Best for Heavy-Duty, Weather-Resistant Outdoor Use

    View on Amazon

    The Brown Hard Shell Roof Cargo Carrier delivers dependable 14 cubic feet of weatherproof storage with a rugged ABS+PC shell, making it a solid choice for outdoor adventures. Its impact-resistant construction can withstand harsh weather, and the tool-free mounting system simplifies installation on cross bars up to 3 inches wide. Compared to the Roof Cargo Box 14 Cubic Feet, its brown finish may be less sleek but offers a more discreet appearance. The lock system enhances security, preventing accidental or theft-related opening. On the downside, users must carefully measure crossbar spacing to ensure compatibility, and the 130-pound weight limit may restrict very heavy or bulky gear. Its durable design suits adventurers and outdoor enthusiasts who need a heavy-duty, weatherproof carrier that’s simple to mount and secure.

    Pros:
    • Impact-resistant, weatherproof shell withstands harsh conditions
    • Tool-free mounting system for quick setup
    • Secure lock with keys enhances security
    Cons:
    • Compatibility depends on accurate crossbar measurement
    • Limited load capacity of 130 pounds

    Best for: Outdoor enthusiasts or travelers needing rugged, weatherproof cargo protection with easy, tool-free installation.

    Not ideal for: Users with very wide or narrow roof bars outside the 3-inch range, or those requiring very high load capacity for heavy gear.

    • Capacity:14 cubic feet
    • Material:ABS+PC shell
    • Load Capacity:130 pounds
    • Dimensions:62.82 × 32.48 × 13.19 inches
    • Color:Brown
    Our verdict
    “This cargo carrier is a durable, outdoor-ready solution perfect for rugged use, with the caveat of precise fit requirements.”

Factors to Consider When Choosing Roofcargo Boxes

Choosing the right roofcargo box involves several considerations beyond just capacity. Understanding these factors helps ensure you pick a model that fits your vehicle, meets your security needs, and offers ease of use. The right cargo box can enhance your trips, while the wrong one may cause inconvenience or even damage, so it’s worth evaluating each aspect carefully.

Capacity and Size

Assess your typical cargo needs carefully. Larger boxes provide more space but tend to be heavier and more cumbersome to handle. Overly small options may save money and weight but limit your packing flexibility for longer trips or family vacations. Consider your vehicle’s roof load capacity as well to avoid exceeding safe weight limits. A balanced size that offers enough room without excessive weight will serve most users well.

Material and Durability

Hard-shell boxes made from high-quality plastics or composites tend to resist impacts and weather better, providing increased security and longevity. Soft-sided cargo bags are lighter and easier to install but generally offer less protection against theft and weather. Think about your climate and security needs; a hard shell might be worth the extra cost if you often travel in harsh conditions or require better security.

Ease of Installation and Compatibility

Look for models with intuitive mounting systems compatible with your vehicle’s roof rack. Some cargo boxes slide onto crossbars easily, while others require tools or more complex setups. Consider the weight of the box itself—heavier models may need additional help to mount safely. Verify compatibility with your roof rack system, as some brands are more universal than others.

Access and Security Features

Dual-side opening designs improve convenience, especially for taller vehicles or tight parking conditions. Locking mechanisms enhance security against theft, a crucial feature if you plan to leave the box unattended. Evaluate the ease of opening and locking; models with smooth, secure latches will save frustration during setup or access.

Price and Value

While premium models offer better durability, aerodynamics, and security, they come at a higher price point. Consider how often you’ll use the cargo box—occasional travelers might prioritize affordability, while frequent users benefit from investing in a high-end option. Avoid overly cheap models that may compromise security or durability, but also beware of paying for features you won’t need.

Frequently Asked Questions

Will a roofcargo box fit on my vehicle?

Most roofcargo boxes are designed to fit a wide range of vehicles, but compatibility depends on your roof rack system and available crossbar width. Before purchasing, measure your roof and verify that your rack can support the box’s mounting requirements. Some models specify compatibility, so checking manufacturer guidelines can prevent fitting issues later.

How much does a roofcargo box weigh, and can I handle it alone?

The weight of cargo boxes varies significantly, from lightweight soft bags under 20 pounds to heavy-duty hard shells over 50 pounds. Lighter models are easier for one person to handle and mount, especially if your vehicle has limited assistance. Heavier options, while more durable, often require extra help or tools for safe installation.

Are roofcargo boxes waterproof?

Most quality hard-shell boxes are designed to be waterproof and resistant to snow, rain, and road spray, especially models with sealed edges and secure locks. Soft-sided cargo bags may offer water resistance but are generally less waterproof, so consider your climate and storage needs carefully. A waterproof design helps protect your gear from weather damage during travel.

Does a roofcargo box affect fuel economy?

Yes, roofcargo boxes can increase aerodynamic drag, leading to slightly higher fuel consumption, especially at highway speeds. Models with sleek, aerodynamic shapes tend to minimize this effect. If fuel efficiency is a priority, investing in a more streamlined design might be worthwhile, particularly if you frequently travel long distances.

How secure are roofcargo boxes against theft?

Security features like integrated locks and sturdy materials enhance theft protection. Hard-shell boxes with locking mechanisms are more secure than soft bags, which can be cut open. Always lock your cargo box when leaving your vehicle unattended, and consider additional security options if you’re leaving valuables inside for extended periods.

Conclusion

For most buyers, the Thule Motion 3 offers the best overall performance, combining capacity, durability, and ease of use. The Thule Force XT XL is an excellent choice for those seeking value without sacrificing too much space or security. If you’re new to roofcargo boxes, models with easier installation and lower weight, like the Brown Hard Shell Roof Cargo Carrier, make excellent entry points. Frequent travelers or large families should consider high-capacity, premium options like the iBirdie Roof Rack Cargo Carrier, while occasional users can save by choosing simpler, budget-friendly models. Your choice should align with your vehicle type, travel frequency, and security needs to make the most of your investment.
