More Details on Our Top Picks

  1. Rooftop Cargo Box Carrier 16 Cu Ft, Dual-Side Universal Fit, Glossy Black

    Rooftop Cargo Box Carrier 16 Cu Ft, Dual-Side Universal Fit, Glossy Black

    Best Overall

    View on Amazon

    This cargo box stands out for its aerodynamic shark-inspired design, which effectively reduces wind drag and noise, making it a quieter and more fuel-efficient option compared to bulkier shapes like the Thule Pulse 2 L. Its 480L capacity is generous for family trips, and dual-side opening enhances accessibility. The quick, drill-free installation on most roof crossbars simplifies setup, but compatibility checks are essential since fit can vary. The weather-resistant construction ensures durability, though color options are limited. Compared to the 14-cubic-foot option, this model offers more space, but it’s slightly bulkier and may require more careful handling during installation.

    Pros:
    • Aerodynamic design reduces wind noise and drag
    • Large 480L capacity ideal for family gear
    • Dual-side opening for easy access
    • Weather-resistant, durable construction
    Cons:
    • Check roof rack compatibility before purchase
    • May require specific roof crossbars for optimal fit
    • Limited color options

    Best for: Families needing ample space and easy access for frequent trips

    Not ideal for: Drivers with non-standard roof racks or limited space for larger boxes

    • Capacity:480L
    • Material:PC+ABS
    • Dimensions:74.4″L x 34.7″W x 11.8″H
    • Internal Length for Snowboard & Ski:176-181 cm
    • Color:Glossy Black

    Our verdict
    “This model suits families seeking a spacious, aerodynamic cargo box with easy installation and access, provided roof compatibility is confirmed.”
  2. Rooftop Cargo Box Hard Shell Cargo Carrier – 14 Cubic Ft, Waterproof, Dual Side Opening, Glossy Black

    Rooftop Cargo Box Hard Shell Cargo Carrier - 14 Cubic Ft, Waterproof, Dual Side Opening, Glossy Black

    Best Value

    View on Amazon

    Compared with larger options like the 21-cubic-foot carrier, this 14-cubic-foot box offers a more affordable choice without sacrificing weatherproofing or dual-side access, making it an excellent value for occasional travelers. Its weatherproof hard shell and secure lock help protect gear during storms or rough conditions, while easy installation requires no special tools. However, at 110 lbs, it’s quite heavy, which could pose challenges during mounting—especially without assistance. Compatibility depends on your roof rack spacing, so verifying fit beforehand is wise. Overall, it strikes a balance between capacity and ease of use for those with moderate storage needs.

    Pros:
    • Large 14 cubic feet capacity for versatile gear
    • Weatherproof and secure locking system
    • Easy to install without special tools
    • Dual side access for convenience
    Cons:
    • Heavy at 110 lbs, might need help for mounting
    • Fitment depends on roof rack spacing
    • Limited to typical roof crossbars

    Best for: Budget-conscious travelers needing reliable weatherproof storage

    Not ideal for: Solo users or those with very heavy or awkward loads requiring lightweight options

    • Capacity:14 cubic feet
    • Weight:110 lbs
    • Color:Glossy Black
    • Material:Hard Shell
    • Opening:Dual Side
    • Weatherproof:Yes
    Our verdict
    “Ideal for casual users seeking a weatherproof, budget-friendly cargo box with straightforward installation.”
  3. Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA

    Rooftop Cargo Carrier, 18 Cu Ft Hardshell, Heavy-Duty, Made in USA

    Best for Heavy-Duty Use

    View on Amazon

    This heavy-duty carrier offers 18 cubic feet of weatherproof storage, making it suitable for those who prioritize durability and robustness over weight. Its HDPE plastic construction ensures resilience against harsh conditions, and the dual side openings allow for easy access. Made in the USA, it appeals to buyers who value domestic manufacturing and rugged quality. Compared with the 16-cubic-foot Thule Pulse, this model provides slightly more space but may be heavier and more challenging to handle alone. Its bulkier build makes it ideal for demanding outdoor trips but less so for urban or apartment dwellers with limited mounting assistance.

    Pros:
    • Heavy-duty, durable HDPE construction
    • Weatherproof with secure locking
    • Made in the USA for quality assurance
    • Dual side opening enhances accessibility
    Cons:
    • Potentially heavier and harder to install alone
    • May require a sturdy roof rack for mounting
    • Limited lightweight portability

    Best for: Outdoor enthusiasts needing rugged, heavy-duty storage for frequent use

    Not ideal for: Urban drivers with limited help or those seeking lightweight options

    • Capacity:18 cubic feet
    • Material:HDPE plastic
    • Dimensions:57 L x 38.5 W x 17.75 H inches
    • Made in:USA
    Our verdict
    “Best suited for users demanding tough, long-lasting cargo solutions for frequent outdoor trips, accepting some handling difficulty.”
  4. Thule Pulse 2 L Roof Mounted Box, 16 Cubic Ft, Dual-Side Opening

    Thule Pulse 2 L Roof Mounted Box, 16 Cubic Ft, Dual-Side Opening

    Best for Ease of Access

    View on Amazon

    The Thule Pulse 2 L excels in providing 16 cubic feet of protected space with dual-side access, making it highly convenient for quick loading and unloading. Its ASA-ABS plastic construction offers excellent weather resistance, rivaling the durability of the heavier, all-metal options like the 21-cubic-foot model. Compared to the larger Thule Force XT XL, the Pulse 2 L is more compact, yet it still offers enough capacity for most travel needs. However, it can be heavy to handle solo, and its limited color options might not suit all aesthetic preferences. This pick is especially good for frequent travelers who value quick access and easy, tool-free attachment.

    Pros:
    • Large 16 cubic feet capacity
    • Dual-side opening for quick access
    • Weather-resistant ASA-ABS material
    • Secure, tool-free attachment system
    Cons:
    • Heavy without assistance during installation
    • Limited color options
    • Less capacity than larger models like the Thule Force XT XL

    Best for: Active travelers who prioritize quick access and reliable weather resistance

    Not ideal for: Users needing maximum capacity or lighter weight for solo installation

    • Capacity:16 cubic feet
    • Load Capacity:75 kg
    • Material:ASA-ABS plastic
    • Opening:Dual-Side
    • Color:Black
    Our verdict
    “This box is ideal for users who want reliable weatherproof storage with easy, quick access from both sides, especially for frequent trips.”
  5. 72 Inch Rooftop Cargo Box Carrier, 21 Cu Ft, Heavy Duty, Black

    72 Inch Rooftop Cargo Box Carrier, 21 Cu Ft, Heavy Duty, Black

    Best for Maximum Capacity

    View on Amazon

    This sizable cargo box offers 21 cubic feet, making it the largest in this lineup and perfect for extensive gear or multiple travelers. Its heavy-duty ABS and PMMA construction provides strong resilience against the elements, whereas the side opening with a support arm simplifies access. Compared with the 16- or 18-cubic-foot options, this model provides significantly more space but at the cost of increased weight and possible difficulty during installation. Its larger size requires ample roof space and sturdy crossbars, but for those needing maximum capacity, this box delivers without sacrificing security thanks to its locking system. It’s an excellent choice for serious outdoor enthusiasts with heavy gear loads.

    Pros:
    • Largest capacity at 21 cubic feet
    • Heavy-duty, weather-resistant construction
    • Easy side opening with support arm
    • Secure locking system
    Cons:
    • Heavy weight may require assistance for mounting
    • Requires ample roof space and sturdy crossbars
    • No explicit weatherproofing details beyond material durability

    Best for: Large families or outdoor adventurers with extensive gear needs

    Not ideal for: Urban drivers or those with limited roof space or crossbars

    • Dimensions:72.83 x 34.25 x 14.76 inches
    • Capacity:21 cubic feet
    • Max Load:150 lbs
    • Material:ABS and PMMA
    Our verdict
    “This carrier is best for those who need maximum storage capacity and rugged durability, accepting the logistical challenge of installation.”
  6. MoNiBloom Rooftop Cargo Box Series (11 Cubic)

    MoNiBloom Rooftop Cargo Box Series (11 Cubic)

    Best Budget-Friendly Basic Storage

    View on Amazon

    The MoNiBloom Rooftop Cargo Box stands out for offering a straightforward, lockable hard-shell design that effectively secures gear during travel. Compared with larger options like the SportRack Vista XL, its 11-cubic-foot capacity is more suited for lighter loads or shorter trips, making it a good fit for those prioritizing affordability and ease of use. However, its smaller size means it’s less ideal for those needing significant cargo space. The weather-resistant shell and simple mounting system make it a reliable choice, but the lack of detailed durability info and a higher price point relative to features could be drawbacks for long-term users. Best for budget-conscious travelers seeking reliable, easy-to-mount storage.
    Specs: Capacity: 11 Cu Ft, Material: Hard Shell, Lockable: Yes, Weight Capacity: 110 lbs, Use: Camping, Road Trips, Model Number: Mnb-rtcb-001

    Pros:
    • Secure lockable hard shell keeps belongings safe
    • Weather-resistant construction protects cargo from elements
    • Easy to install on most roof racks
    • Compact and lightweight for simple handling
    Cons:
    • Limited to 11 cubic feet capacity, restricting larger loads
    • No detailed info on long-term durability
    • Price may be higher relative to its size

    Best for: Budget-conscious families or occasional travelers who need a secure, compact cargo solution

    Not ideal for: Heavy-duty users or those requiring maximum capacity, as its 11 Cu Ft is limited for larger gear loads

    • Capacity:11 Cubic Feet
    • Material:Hard Shell
    • Lockable:Yes
    • Weight Capacity:110 lbs
    • Use:Camping, Road Trips
    • Model Number:Mnb-rtcb-001
    Our verdict
    “Ideal for budget-conscious users seeking reliable, moderate-capacity cargo storage for short trips.”
  7. GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Roof Luggage Storage

    GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening Roof Luggage Storage

    Best for Easy Access and Versatile Fit

    View on Amazon

    The GarveeTech Rooftop Cargo Box offers 12 cubic feet of storage with dual-sided opening, making access more convenient than some traditional single-side models like the Thule Force XT XL. Its durable ABS construction withstands weather and UV exposure, and its universal fit appeals to a broad range of vehicles. While the dual-sided access is a clear advantage, potential buyers should verify roof rack compatibility ahead of purchase, as the box requires a suitable mounting system. It’s better suited for drivers who value quick access and flexible loading but might be less appealing for those with non-standard roof rack setups. This model balances durability and convenience, with some consideration needed for compatibility.
    Specs: Material: ABS, Capacity: 12 Cu Ft, Dimensions: 54.3″L x 31.5″W x 13.4″H, Max Capacity: 165 lbs, Features: Dual-sided opening, waterproof, UV-resistant

    Pros:
    • Durable, weather-resistant ABS construction
    • Generous 12 cubic feet of storage
    • Dual-sided access with keys and straps
    • Universal fit for most roof racks
    Cons:
    • Compatibility with roof racks needs confirmation
    • Limited to vehicles equipped with roof racks
    • Size may require careful measurement for fit

    Best for: Travelers who prioritize easy access and compatibility across various vehicles

    Not ideal for: Owners with non-standard or incompatible roof rack systems, as verification is necessary

    • Material:ABS
    • Capacity:12 Cu Ft
    • Dimensions:54.3″L x 31.5″W x 13.4″H
    • Max Capacity:165 lbs
    • Features:Dual-sided opening, waterproof, UV-resistant
    Our verdict
    “Best suited for users who want quick, flexible access to cargo with durable protection and broad vehicle compatibility.”
  8. Thule Force XT XL Roof Cargo Box

    Thule Force XT XL Roof Cargo Box

    Best for Sleek, Everyday Use

    View on Amazon

    The Thule Force XT XL is designed for those who demand a stylish, durable carrier capable of handling daily trips. Its sleek profile and extensive safety testing set it apart from bulkier options like the SportRack Vista XL, which offers a larger 18 Cu Ft capacity but with less emphasis on aesthetics. The Thule’s quick, secure mounting system and dual-sided access provide peace of mind and convenience, though it can be fairly bulky to store when not in use. While its design emphasizes reliability and easy handling, the limited info on weight capacity might concern heavier loads. This pick makes sense for active users seeking a balance of form and function for regular use.
    Specs: Brand: Thule, Model Number: 645850, Includes: Rooftop cargo carrier box, Warranty: Limited Lifetime

    Pros:
    • Sleek, durable design suitable for daily use
    • Easy, secure mounting with safety indicators
    • Dual-sided access simplifies loading/unloading
    • Extensively tested for safety and reliability
    Cons:
    • May be bulky to handle and store when not mounted
    • Limited info on maximum weight capacity
    • Price may be higher for a mid-range model

    Best for: Urban or active users needing a reliable, stylish cargo box for frequent use

    Not ideal for: Those with very tight storage space at home or needing maximum capacity for large trips, due to its bulk

    • Brand:Thule
    • Model Number:645850
    • Included Components:Rooftop cargo carrier box
    • Warranty:Limited Lifetime
    Our verdict
    “Best for users prioritizing style, reliability, and frequent access over maximum capacity.”
  9. TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier

    TUFFIOM 13.4 cu.ft. Rooftop Cargo Box with Keys, Waterproof Hard Shell Travel Roof Storage Carrier

    Best for Larger, Secure Storage

    View on Amazon

    The TUFFIOM 13.4 Cu.Ft. Cargo Box offers a sizable 13.4 cubic feet of space, making it an excellent choice for families or travelers with substantial gear. Its waterproof ABS shell and dual-side opening enhance usability and protection, especially when compared to smaller models like the MoNiBloom. The secure locking system with keys adds peace of mind, though the installation requires crossbars, which might not suit all vehicles, and its weight of approximately 24.25 lbs could make handling tricky for some. This model strikes a balance between capacity and weather resistance, but users should verify compatibility and be prepared for some handling effort.
    Specs: Capacity: 13.4 Cu Ft, Dimensions: 61″ L x 27.6″ W x 13.8″ H, Material: ABS, Max Load: 150 lbs, Locking: Yes, Warranty: 3 years

    Pros:
    • Large 13.4 cubic feet storage capacity
    • Waterproof ABS shell offers weather protection
    • Dual-side opening for easy access
    • Secure locking with keys
    Cons:
    • Requires crossbars for installation, not universal
    • Weight of about 24.25 lbs can be cumbersome
    • Protective film on lid must be removed before use

    Best for: Large families or frequent travelers needing maximum cargo capacity with weather protection

    Not ideal for: Drivers with non-standard roof rack setups or limited physical strength for handling heavier units

    • Capacity:13.4 Cu Ft
    • Dimensions:61″ L x 27.6″ W x 13.8″ H
    • Material:ABS
    • Max Load Capacity:150 lbs
    • Locking System:Yes, with keys
    • Warranty:3 years
    Our verdict
    “Ideal for larger households or long trips where maximum secure storage is needed, provided vehicle compatibility is confirmed.”
  10. SportRack Vista XL Rear Opening Cargo Box

    SportRack Vista XL Rear Opening Cargo Box

    Best for Maximum Capacity and Easy Rear Access

    View on Amazon

    The SportRack Vista XL offers a substantial 18 cubic feet of storage, making it one of the largest options in this lineup. Its rear-opening design facilitates quick access without unloading entire contents, a feature not present on the Thule Force XT XL. Its UV-resistant ABS shell ensures durability against the elements, and tool-free mounting simplifies installation, appealing to those who want quick setup. While its size is advantageous for large families or extensive gear, its bulk and weight—up to 100 pounds—may challenge solo handling. Its limited color options and slightly less refined aesthetic compared to premium brands like Thule make it less suited for those seeking a sleek look.
    Specs: Capacity: 18 Cu Ft, Material: UV-resistant ABS, Dimensions: 63 x 38 x 19 inches, Max Weight: 100 lbs, Compatibility: 23 5/8 – 29 3/4 inch crossbar spacing

    Pros:
    • Large 18 cubic feet capacity for extensive gear
    • Rear opening provides easy access
    • Tool-free, quick mounting hardware
    • UV-resistant durable shell
    Cons:
    • Heavy—may be difficult to handle alone
    • Size may not fit all vehicles or storage spaces
    • Limited color options

    Best for: Families or groups needing maximum cargo space with easy rear access for frequent loading

    Not ideal for: Solo travelers or those with compact or non-standard racks, due to weight and size

    • Capacity:18 Cu Ft
    • Material:UV-resistant ABS
    • Dimensions:63 x 38 x 19 inches
    • Max Weight:100 pounds
    • Compatibility:23 5/8 – 29 3/4 inches crossbar spacing
    Our verdict
    “Best for large families or groups that need maximum cargo space with easy rear access, accepting the bulk and weight involved.”
  11. RoofPax XXL 28 cuft Car Rooftop Cargo Carrier Bag with Waterproof Design and Heavy Duty Tie Down Straps

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

    Best for Large Capacity and Versatile Compatibility

    View on Amazon

    The RoofPax XXL stands out for its enormous 28 cubic feet capacity, making it ideal for extended family trips or bulky gear. Unlike the Thule Pulse 2 M, which offers only 14 cubic feet, this bag provides nearly double the volume, though it involves a more complex installation process due to its heavy-duty straps and adjustable mounting system. Its waterproof construction and included lock ensure gear stays dry and secure in unpredictable weather. However, the larger size and weight of the carrier can make handling and installation more cumbersome, especially for users with limited strength or smaller vehicles. Compared to rigid boxes, this soft carrier offers more flexibility in storage and compatibility, but the installation process can be tricky for first-timers.

    Pros:
    • Enormous 28 cuft capacity for extensive gear
    • Secure patented mounting system for safety
    • Weatherproof design protects gear in diverse conditions
    • Includes all necessary accessories for installation
    Cons:
    • Installation can be complex and time-consuming
    • Heavy-duty straps may be awkward to handle

    Best for: Families or groups needing maximum storage capacity and adaptable mounting options on larger vehicles

    Not ideal for: Solo travelers or those with smaller cars who prioritize quick setup and lightweight options

    • Capacity:28 cuft
    • Waterproof:Yes
    • Includes:4 tie down straps, 4 hooks, lock, storage bag
    • Compatibility:Fits vehicles with or without roof racks, raised side rails, or crossbars
    • Warranty:Lifetime on zippers, 5-year on fabric
    Our verdict
    “This carrier suits those who prioritize capacity and versatility over ease of installation and weight management.”
  12. Thule Pulse 2 M Roof-Mounted Box, 14 Cubic Ft, Dual-Side Opening

    Thule Pulse 2 M Roof-Mounted Box, 14 Cubic Ft, Dual-Side Opening

    Best for Convenience and Quick Access

    View on Amazon

    The Thule Pulse 2 M excels in offering dual-side opening for effortless access, making it a clear choice over the more cumbersome RoofPax XXL when quick retrieval of gear is needed. Its 14 cubic feet capacity is ideal for those who carry moderate loads like luggage, skis, or snowboards. The tool-free installation with a torque indicator simplifies setup, especially compared to larger soft carriers, but its 75 kg load limit might restrict heavier gear or multiple bulky items. Designed with durable ASA-ABS plastic, it withstands harsh weather, though its size can be bulky for smaller vehicles, potentially affecting aerodynamics and fuel efficiency. Compared to larger capacity options, it offers less storage but prioritizes ease of use and durability.

    Pros:
    • Dual-side opening provides quick, easy access from either side
    • Secure, tool-free installation with torque indicator ensures proper setup
    • Weather-resistant ASA-ABS plastic withstands harsh conditions
    • Lightweight and durable construction
    Cons:
    • Limited to 75 kg (165 lbs) load capacity, restricting heavier gear
    • Size may be bulky for compact vehicles

Factors to Consider When Choosing Rooftop Cargo Boxes

Choosing the right rooftop cargo box involves understanding your travel habits, vehicle compatibility, and the features that matter most. I’ll walk through key considerations that can help you avoid common pitfalls and make a smarter purchase, whether you need maximum capacity, quick installation, or rugged durability.

Capacity and Size

Assess your typical packing volume to select a cargo box that fits your needs without overloading your vehicle’s roof. Larger models offer more space but can be heavier and more difficult to install. Conversely, smaller options are easier to handle but may limit your luggage. Think about your most common trips—do you carry gear for a family, sports equipment, or just extra luggage? Matching capacity to your needs prevents overspending on unnecessary space or struggling with tight fits.

Ease of Installation and Access

Look for models with dual-side opening if you frequently access your cargo from a parked vehicle, as this simplifies loading and unloading. Ease of installation varies; some boxes snap into place with minimal tools, while others might require additional equipment or professional help. Consider whether your vehicle’s roof rack system is compatible—some cargo boxes come with universal mounting kits, others need specific rails. Ease of access can save time and reduce frustration, especially on long trips.

Durability and Weatherproofing

Since rooftop cargo boxes are exposed to the elements, prioritize models with hard shells made from impact-resistant materials and sealed edges to prevent water ingress. Waterproofing adds to the longevity of your gear and keeps your luggage dry in rain or snow. Keep in mind, however, that highly durable, waterproof models are often heavier, which could impact ease of handling and fuel efficiency. Balancing robustness with manageable weight is key for many users.

Material and Build Quality

High-quality plastics like ABS or fiberglass composites offer strength without excessive weight, but they come at a higher price. Cheaper models may use thinner materials that crack or deform over time. Check for reinforced hinges, secure locks, and sturdy mounting brackets to ensure safety and longevity. A well-built cargo box might cost more upfront but can save money in repairs or replacements over time.

Price and Value

While budget options under $300 can be suitable for occasional use, heavier-duty models with advanced features tend to be in the $500–$800 range. Consider how often you’ll use the box and whether the extra features justify the higher price. Investing in a more durable, secure model can be worthwhile for frequent travelers or harsh weather conditions. Conversely, casual users might prioritize affordability and simplicity.

Frequently Asked Questions

Will a rooftop cargo box fit on my vehicle?

Most rooftop cargo boxes are designed to fit a wide range of vehicles, but compatibility depends on your roof rack system’s type and strength. Check your vehicle’s roof load capacity and ensure your roof rails or crossbars can support the weight of the cargo box plus your gear. Many models specify maximum vehicle width and compatibility details, which should be verified before purchase to avoid installation issues or safety concerns.

Are rooftop cargo boxes secure enough for winter conditions?

Yes, many high-quality cargo boxes are built to withstand winter weather, featuring impact-resistant shells and waterproof seals. Locks add an extra layer of security against theft, which is especially important in colder months when cars are parked in public spaces. Always confirm that the model you choose has reinforced locking mechanisms and weatherproofing to ensure your gear stays dry and safe during winter trips.

How much additional fuel will a rooftop cargo box consume?

Adding a cargo box increases aerodynamic drag, which can lead to slightly higher fuel consumption—often around 5-15% depending on the size and shape of the box. Larger, boxy models tend to have a bigger impact than sleek, low-profile options. To minimize this effect, choose a more aerodynamic design and ensure proper installation. Planning for a small fuel cost increase is wise when considering larger or heavier cargo boxes.

Is it difficult to install a rooftop cargo box myself?

Installation difficulty varies by model, but many boxes feature user-friendly mounting systems that can be installed with basic tools and minimal experience. Some models include clear instructions and quick-mount systems, making DIY setup feasible for most car owners. However, for larger or heavier boxes, or if your vehicle’s roof rack is unconventional, professional installation might be advisable to ensure safety and proper fit.

What features should I prioritize for frequent use?

For frequent use, prioritize a model with dual-side opening for easy access, durable waterproof construction, and a locking mechanism for security. Ease of installation and removal is also key, especially if you switch vehicles or store the box when not in use. Investing in a slightly higher-priced model with reinforced hinges and a robust locking system can pay off over time, providing peace of mind and minimizing maintenance issues.

Conclusion

For most buyers, the Thule Force XT XL offers the best balance of capacity, durability, and ease of use, making it ideal as the overall top pick. Families or frequent travelers seeking maximum space should consider larger models like the 72 Inch Rooftop Cargo Box Carrier for extended trips. Those on a tighter budget or with casual needs will find the Rooftop Cargo Box Carrier 16 Cu Ft to be a reliable, affordable choice. For beginners or infrequent users, simple, lightweight options with easy installation and decent weatherproofing will suffice. If you need rugged, heavy-duty performance, premium models like the Thule Pulse 2 M provide robust features at a higher price point. Tailor your choice based on how often and how intensely you plan to use your rooftop cargo box.
