More Details on Our Top Picks

  1. GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof Hard Shell, Black

    GarveeTech Rooftop Cargo Box Carrier, 165 LBS Capacity, Dual-Side Opening, Waterproof Hard Shell, Black

    Best Overall for Versatile All-Weather Use

    View on Amazon

    This model stands out for its combination of durability, capacity, and ease of access, making it a strong contender against the Garvee Heavy Duty Carrier, especially with its dual-sided opening that simplifies loading. Compared to soft-sided options like the MIDABAO, it offers superior weather protection and security, but it requires a compatible roof rack, which could limit some vehicle options. Its sturdy ABS shell ensures safe travel in rain or snow, and the 12 cubic feet capacity provides ample space for most gear. While slightly more complex to install, its universal fit and reliable waterproof design make it a practical choice for year-round travel.

    Pros:
    • Durable, waterproof ABS construction protects luggage in all weather
    • Large 12 cubic feet capacity expands cargo space significantly
    • Dual-sided opening allows easy access from either side
    • Universal fit with most roof rack systems
    Cons:
    • Requires roof rack compatibility, not suitable for all vehicles
    • Installation can be complex for some users

    Best for: SUV owners needing a durable, weatherproof cargo solution with easy access from both sides

    Not ideal for: Drivers without roof racks or seeking a lightweight, soft carrier for occasional use

    • Material:ABS plastic
    • Capacity:12 cubic feet
    • Weight Capacity:165 lbs
    • Dimensions:54.3 in L x 31.5 in W x 13.4 in H
    • Color:Black

    Our verdict

  2. Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box

    Best for Easy Installation and Budget-Friendly Travel

    View on Amazon

    This universal ABS plastic cargo box offers straightforward setup and reliable weather resistance, making it an excellent choice for casual travelers compared to the GarveeTech. While it lacks the dual-sided opening of the GarveeTech, its simple design and secure lock support hassle-free trips, especially for vehicles equipped with cross bars. Its 11 cubic foot capacity balances ample storage with manageable weight, and its weatherproof shell ensures protection during unexpected rainstorms. However, its fit is limited to vehicles with cross bars, and it offers fewer color options, which might matter for style-conscious buyers.

    Pros:
    • Durable, weather-resistant ABS construction
    • Secure lock for safe storage
    • Easy to install without tools
    • Ample capacity for long trips
    Cons:
    • Fits only vehicles with cross bars, limiting compatibility
    • May be difficult to open in cold weather

    Best for: Budget-conscious car owners with cross bars seeking reliable weatherproof capacity

    Not ideal for: Owners without cross bars or those needing dual access for easier loading

    • Material:ABS plastic
    • Capacity:11 cubic feet
    • Dimensions:53 x 34 x 15 inches
    • Weight Capacity:110 lbs
    • Color:Black
    • Mounting Type:Universal cross bar fit
    Our verdict
    “This cargo box suits casual travelers with cross bars seeking a simple, weatherproof, and affordable rooftop storage solution.”
  3. MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks Option

    MIDABAO 20 Cubic Waterproof Car Roof Top Carrier - Cargo Roof Bag with Anti Slip Mat and Racks Option

    Best for Large Capacity and Versatile Fit

    View on Amazon

    This soft PVC carrier offers an impressive 20 cubic feet of space, surpassing many hard-shell options like the GarveeTech and TUFFIOM, making it ideal for bulky gear. Its waterproof design and multiple mounting straps ensure contents stay dry in heavy rain, and it fits any vehicle with or without roof racks, providing flexibility. However, as a soft carrier, it may not withstand extreme impacts or rough handling as well as hard shells. Proper tensioning of straps is crucial to prevent movement, and it offers limited aesthetic options. It’s best suited for those prioritizing maximum capacity and adaptable fitting, rather than rugged durability.

    Pros:
    • Huge 20 cubic feet capacity for bulky gear
    • Waterproof PVC material keeps contents dry
    • Fits all vehicles with or without roof racks
    • Easy to mount and store
    Cons:
    • Less durable than hard-shell options
    • Requires proper strap tension for security

    Best for: Families or adventure travelers needing maximum cargo space and flexible installation on all vehicle types

    Not ideal for: Owners seeking hard-shell protection or traveling in very rough conditions

    • Capacity:20 Cubic Feet
    • Material:PVC
    • Dimensions:51.1” x 39” x 17”
    • Includes:Anti Slip Mat, mounting straps
    • Fits:All cars with or without roof rack
    Our verdict
    “This roof bag is perfect for those needing maximum capacity and adaptable fit across various vehicle types, especially for bulky gear.”
  4. 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 Secure Storage and Long-Term Durability

    View on Amazon

    This hard-shell cargo box balances size and security, offering 13.4 cubic feet of storage with a lockable system that surpasses soft options for safety. Compared with the GarveeTech, it provides a more compact footprint but maintains robust waterproofing, thanks to its ABS construction. Its dual-side opening simplifies access, and the three-year warranty indicates confidence in its durability. However, it requires specific crossbar widths and spacing, which could complicate installation for some vehicles. Its weight of over 24 pounds also makes lifting more challenging during mounting.

    Pros:
    • Secure locking system with keys for peace of mind
    • Durable ABS waterproof construction
    • Dual-side opening for easy access
    • Three-year warranty adds confidence
    Cons:
    • Requires specific crossbar width and spacing
    • Heavy to lift during installation

    Best for: SUV or van owners prioritizing security and long-term durability in all weather conditions

    Not ideal for: Those seeking the largest possible capacity or easy installation without specific crossbar measurements

    • Capacity:13.4 cubic feet
    • Dimensions:61″ L x 27.6″ W x 13.8″ H
    • Material:ABS
    • Locking System:Yes, with keys
    • Warranty:3 years
    • Max Crossbar Width:2.36″
    Our verdict
    “This cargo box is ideal for owners needing a secure, durable, and weatherproof storage solution for long-term use.”
  5. 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 Heavy-Duty Capacity for Rugged All-Weather Use

    View on Amazon

    This model offers a substantial 18 cubic feet of weatherproof storage in a rugged HDPE shell, making it well-suited for demanding conditions, especially compared to the more lightweight or soft-sided options like the MIDABAO. Its dual side locking enhances security during extended trips, and the high-capacity interior ensures ample room for luggage or gear. The made-in-USA quality suggests reliability, but its weight and size could pose challenges for installation, especially on vehicles without compatible roof racks. Limited color options might also be a consideration for style preferences.

    Pros:
    • Heavy-duty HDPE shell provides exceptional durability
    • Weatherproof and secure with dual side locks
    • Large capacity for extensive gear storage
    • Made in the USA ensures quality craftsmanship
    Cons:
    • Heavy and potentially difficult to install
    • Requires compatible roof racks for mounting

    Best for: Adventure travelers needing a tough, weatherproof carrier capable of handling rough conditions

    Not ideal for: Owners with limited access to suitable roof racks or seeking lightweight carriers for occasional trips

    • Capacity:18 cubic feet
    • Material:HDPE plastic
    • Dimensions:57 L x 38.5 W x 17.75 H inches
    • Made in:USA
    Our verdict
    “This heavy-duty carrier is perfect for rugged adventures where durability and weatherproofing are paramount, despite its weight and installation complexity.”
  6. 12 Cubic Rooftop Cargo Box Carrier, Dual-Side Opening Hard-Shell Vehicle Roof Mount Travel Luggage Storage, 135Lbs Capacity, Black

    12 Cubic Rooftop Cargo Box Carrier, Dual-Side Opening Hard-Shell Vehicle Roof Mount Travel Luggage Storage, 135Lbs Capacity, Black

    Best Overall for Versatile and Aerodynamic Storage

    View on Amazon

    This cargo box strikes a balance between capacity and ease of access, making it a versatile choice for most travelers. Its 12 cubic feet of space and dual-sided opening provide convenient access, especially compared to rear-opening options like the SportRack Vista XL, which can be less intuitive for frequent loading. The aerodynamic ABS shell helps reduce wind noise and drag, translating into better fuel efficiency. However, its compatibility depends on verifying roof rack fit, and the included security measures may need reinforcement for high-value gear. Compared to larger options, this model offers a manageable size for urban and suburban vehicles, but it may not suit those needing maximum volume.

    Pros:
    • Durable waterproof ABS construction
    • Moderate 12 cubic feet capacity
    • Dual-sided opening for quick access
    • Aerodynamic design reduces wind resistance
    Cons:
    • Requires roof rack compatibility verification
    • Includes only 2 straps and 2 keys, may need extra security measures

    Best for: SUV owners seeking a reliable, easy-to-access cargo solution that improves fuel efficiency.

    Not ideal for: Travelers with very heavy loads exceeding 135 lbs or those with incompatible roof racks.

    • Material:ABS
    • Capacity:12 cubic feet (340L)
    • Dimensions:54.3″L x 31.5″W x 13.4″H
    • Weight Capacity:135 lbs
    • Color:Black
    • Opening:Dual-sided
    Our verdict
    “This model is ideal for drivers who want a balanced, weatherproof cargo box with easy access and good fuel economy.”
  7. Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier – 69″ x 33″ x 11″, Waterproof, Lockable, 17 Cu Ft, 165 Lb Capacity

    Garvee Heavy Duty Hard Shell Roof Top Cargo Carrier - 69" x 33" x 11", Waterproof, Lockable, 17 Cu Ft, 165 Lb Capacity

    Best for Heavy Loads and Outdoor Adventures

    View on Amazon

    Compared with the 12 cubic foot options like the previous pick, this Garvee carrier offers a larger 17 cubic feet of space and a higher 165 lbs weight limit, making it better suited for heavy-duty outdoor gear. Its UV-resistant ABS shell enhances durability in harsh weather, and the lockable feature adds security during extended stops. The tool-free installation process is a major convenience, but it might not fit vehicles without compatible roof racks, similar to the smaller models. Its larger size could be less aerodynamic, potentially increasing wind noise and drag at highway speeds. This choice appeals to adventure seekers who prioritize capacity and ruggedness over sleekness.

    Pros:
    • Large 17 cubic feet capacity
    • Heavy-duty UV-resistant ABS shell
    • Lockable for security
    • Easy tool-free installation
    Cons:
    • May not fit all roof racks
    • Larger size may increase wind noise and drag

    Best for: Outdoor enthusiasts needing a rugged, high-capacity cargo box for long trips and heavy gear.

    Not ideal for: Urban drivers with limited roof space or those seeking the most aerodynamic option.

    • Dimensions:69″ L x 33″ W x 11″ H
    • Capacity:17 Cu Ft
    • Weight Capacity:165 lbs
    • Material:ABS plastic with UV-resistant coating
    • Installation:Tool-free, hardware included
    • Color:Black
    Our verdict
    “This cargo box is perfect for users who require maximum capacity and rugged weatherproofing for outdoor adventures.”
  8. GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12/14 Cubic Feet, Waterproof Hard Shell

    GarveeTech Rooftop Cargo Box Carrier, Dual-Side Opening, 12/14 Cubic Feet, Waterproof Hard Shell

    Best for Versatile Sizing and Universal Fit

    View on Amazon

    Offering flexibility with 12 to 14 cubic feet of space, the GarveeTech cargo box caters to a broad range of vehicles, provided they have roof racks compatible with its dimensions. Its dual-sided opening makes loading and unloading more convenient than rear-only access, similar to the 12 cubic foot model but with slightly more capacity options. The waterproof ABS shell ensures protection against the elements, yet some users report installation challenges, especially without detailed hardware information. Its universal fit makes it suitable for most roof racks, but it may be limited for those without proper mounting points or seeking the largest capacity available.

    Pros:
    • Durable waterproof ABS construction
    • Flexible capacity (12/14 cu ft)
    • Universal fit with roof rack compatibility
    • Dual-sided opening for convenience
    Cons:
    • Limited installation guidance
    • Some concerns over ease of mounting

    Best for: Drivers seeking adaptable capacity with easy access and weatherproof protection, suitable for various vehicle types.

    Not ideal for: Owners of vehicles without compatible roof racks or those needing the absolute maximum capacity.

    • Material:ABS
    • Capacity:12/14 cubic feet
    • Dimensions:54.3″L x 31.5″W x 13.4″H / 62.2″L x 31.5″W x 13.4″H
    • Weight Capacity:165 lbs
    • Color:Black
    • Includes:2 keys, 2 straps
    Our verdict
    “This cargo box is a strong choice for those needing adaptable capacity and easy access on a variety of vehicles.”
  9. SportRack Vista XL Rear Opening Cargo Box

    SportRack Vista XL Rear Opening Cargo Box

    Best for Maximum Capacity and UV Resistance

    View on Amazon

    The Vista XL provides 18 cubic feet of storage, making it the largest in this lineup, ideal for families or groups with substantial gear. Its rear-opening design is less intuitive for frequent access but offers a secure, weather-resistant way to store bulky items. Made from UV-resistant ABS, it withstands sun exposure well, yet the maximum weight capacity of 100 pounds limits heavy loads, especially compared to the Garvee models. The tool-free mounting system simplifies setup, but the rear opening might be cumbersome for quick access in tight parking situations. This box is suitable for those prioritizing volume over ease of access.

    Pros:
    • Largest capacity at 18 cu ft
    • UV-resistant durable construction
    • Tool-free mounting
    • Secure locking system
    Cons:
    • Rear opening less convenient for frequent access
    • Limited to 100 lbs load capacity
    • Compatibility depends heavily on roof rack system

    Best for: Large families or groups with bulky gear needing maximum storage capacity and UV resistance.

    Not ideal for: Solo travelers or those who prefer front or side access for frequent loading/unloading.

    • Capacity:18 cubic feet (510L)
    • Material:UV-resistant ABS
    • Dimensions:63 x 38 x 19 inches
    • Max Weight Capacity:100 pounds
    • Included Components:Roof box and mounting hardware
    • Warranty:25 years
    Our verdict
    “This cargo box is best for users prioritizing volume and UV protection, willing to accept less convenient access.”
  10. Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier, Lockable & Weatherproof

    Rough Country Rooftop Cargo Box 14.5 Cu Ft – Hard Shell Roof Rack Storage Carrier, Lockable & Weatherproof

    Best Budget-Friendly Weatherproof Storage

    View on Amazon

    This 14.5 cubic foot cargo box offers a practical solution for outdoor gear, especially considering its affordable price point. Its UV-protected ABS shell provides reliable weatherproofing, comparable to premium models like GarveeTech, but it supports slightly less weight at 125 lbs. Installation is straightforward without drilling, compatible with most crossbar systems, yet it may not fit all vehicle types equally well. The shape is aerodynamic enough for typical highway speeds, though it doesn’t significantly cut wind noise, which can increase at higher speeds. This pick makes the most sense for budget-conscious buyers seeking reliable weatherproof storage without sacrificing basic features.

    Pros:
    • Weatherproof and UV-protected
    • Easy no-drill installation
    • Lockable for security
    • Durable ABS construction
    Cons:
    • Supports only 125 lbs
    • Aerodynamic shape offers limited noise reduction at high speeds

    Best for: Budget-conscious travelers needing weatherproof, lockable storage for outdoor activities.

    Not ideal for: Those requiring the highest capacity or very heavy loads, as it supports only 125 lbs.

    • Capacity:14.46 cu ft
    • Interior Dimensions:65in L x 32in W x 13in H
    • Material:High-impact ABS with UV protection
    • Weight Support:125 lbs
    • Installation:No drill, universal crossbar fit
    • Made in:USA
    Our verdict
    “This cargo box balances affordability and weatherproofing, suitable for casual outdoor use and moderate loads.”

Factors to Consider When Choosing All Weather Cargo Box Rooftop

Selecting the right all weather cargo box involves considering multiple factors beyond just capacity. Understanding weatherproofing quality is vital, but so is compatibility with your vehicle and ease of access. Other considerations include security features, installation complexity, and overall durability to withstand harsh conditions. Being aware of these broader issues helps prevent common mistakes, such as underestimating capacity needs or choosing models that are difficult to mount or access in bad weather. This guide breaks down these factors to help you make an informed decision tailored to your specific travel and storage demands.

Weatherproofing and Material Durability

For rooftop cargo boxes, weatherproofing is paramount. Hard-shell models with robust, waterproof materials like reinforced ABS or polycarbonate typically provide better protection against snow, rain, and UV exposure. If you frequently drive in severe weather, investing in a model with sealed edges and lockable lids will help keep your gear dry and secure. Bear in mind that cheaper models may claim waterproofing but lack the necessary sealing, leading to leaks over time. Durability also matters—look for reinforced construction that resists cracking or warping with temperature fluctuations.

Capacity and Size Compatibility

Capacity varies widely among options, from compact 12 cubic feet bags to larger 18+ cubic feet boxes. Consider your typical load size and whether the box can fit on your vehicle’s roof without obstructing visibility or interfering with other accessories. Larger models often require stronger roof racks and may be harder to install, but they provide much-needed space for family trips or bulky gear. Smaller boxes are easier to handle and install but can be limiting if you carry a lot of equipment. Measure your roof and check dimensions carefully before purchasing.

Ease of Access and Installation

Dual-side opening models offer significant convenience, especially when loading or unloading in tight spaces or on busy roads. Ease of installation depends on the mounting system—look for models with straightforward, tool-free options if you’re not a DIY enthusiast. Consider whether the box has features like quick-release clamps or integrated locks, which can save time and improve security. Keep in mind that heavier, larger boxes might require additional help during installation, and some models may need specific rack systems compatible with your vehicle.

Security Features and Locking Mechanisms

Security is essential if you plan to leave your cargo unattended, especially during stops or overnight stays. Lockable lids and sturdy locking mechanisms prevent theft and unauthorized access. Hard-shell models generally offer better security than soft-sided bags, which are more vulnerable to tampering. Some models include keyed locks or even alarm systems, providing extra peace of mind. Remember that adding security features can slightly increase the overall cost but often pays off in peace of mind during long trips.

Pricing and Value

Prices vary significantly based on size, material, and features. Budget models often provide adequate weatherproofing but may lack durability or security. Premium options with reinforced shells, larger capacities, and advanced locking systems tend to cost more but last longer and perform better in severe conditions. Striking the right balance between cost and features is key—consider how often you’ll use the box and in what conditions. Investing in a slightly more expensive, high-quality model can save money in the long run by avoiding replacements or repairs.

Frequently Asked Questions

Will a larger cargo box fit on my vehicle’s roof without causing issues?

Before purchasing a larger cargo box, measure your vehicle’s roof dimensions and check your roof rack’s weight capacity. Not all roofs can support heavy or bulky boxes safely, and overloading can affect vehicle handling and safety. Many manufacturers provide compatibility charts or dimensions that help determine fit. If you’re unsure, consulting your vehicle’s manual or a professional installer can prevent problems down the line. Remember, even if the box fits, ensure it doesn’t obstruct your view or interfere with other roof accessories.

How weatherproof are soft-sided cargo bags compared to hard-shell options?

Soft-sided cargo bags are generally less weatherproof than hard-shell models, especially in heavy rain or snow. While many soft bags feature water-resistant fabrics and sealed seams, they often lack the rigid structure needed to withstand extreme weather conditions or impacts. Hard-shell boxes, made from reinforced plastics, provide a more reliable barrier against water ingress and physical damage. If you frequently travel in severe weather, a hard-shell option is typically the safer choice, though soft bags can suffice for light rain or mild conditions.

Is it worth paying extra for a lockable cargo box?

Investing in a lockable cargo box adds a valuable layer of security, especially if you leave your vehicle unattended for extended periods. Lockable models deter theft and tampering, protecting your gear from opportunistic thieves. While they may come at a higher cost, the peace of mind they offer often justifies the expense, particularly in busy or insecure areas. Ensure the lock is of good quality and resistant to weather and tampering, and always lock your box when not in use for maximum security.

How important is ease of installation for a rooftop cargo box?

Ease of installation can significantly impact your overall experience, especially if you frequently remove or switch boxes. Models with straightforward mounting systems, such as quick-release clamps or tool-free setups, save time and reduce frustration. Proper installation is crucial for safety—an improperly mounted box can come loose or cause handling issues. If you’re not comfortable with DIY tasks, choosing a model with clear instructions and easy mounting features can prevent headaches and ensure your cargo remains secure during travel.

Are there specific features to look for if I need a cargo box for winter conditions?

For winter use, focus on models with weatherproofing features such as sealed lids, reinforced shells, and corrosion-resistant hardware. A box with a secure locking system prevents snow and ice from entering, and a sturdy mounting system ensures stability in windy or snowy conditions. Some models are designed with additional insulation or UV resistance to handle prolonged exposure to harsh sunlight and cold temperatures. Investing in a well-built, weatherproof cargo box can make winter trips safer and more convenient, protecting your gear from the elements.
