FIVKLEMNZ 21 Cubic Feet Waterproof Car Rooftop Cargo Carrier Roof Bag with Accessories
This soft-sided roof bag excels in versatility, offering a generous 21 cubic feet of waterproof storage that can accommodate high volumes of luggage and gear. Compared to rigid options like the Rooftop Cargo Box Carrier (B0H1PS8BHW), it provides more flexibility for irregularly shaped items and is easier to store when not in use. Its heavy-duty 840D PVC fabric ensures durability and weather resistance, but the bulkiness and weight can make installation and handling more challenging. The included accessories, like the anti-slip mat and luggage lock, enhance security and ease of setup. However, first-time users may find securing the straps requires some patience, and the large size might be impractical for small or low-clearance vehicles. Still, for those needing maximum capacity and weatherproof protection, this roof bag delivers.
Pros:- Waterproof and heavy-duty construction keeps contents dry in adverse weather
- Large capacity fits multiple suitcases, tents, and gear
- Universal fit accommodates all vehicle types with or without roof racks
- Complete travel kit simplifies installation
Cons:- Installation can be effortful for first-time users

Rooftop Cargo Box Carrier, 17 Cu ft Hard Shell Rooftop Cargo Carrier – Dual-Side Opening, Universal Fit, Waterproof ABS, 165 lbs Capacity with Secure Straps & Keys
This hard-shell cargo box prioritizes security and aerodynamics, with a 17 cubic feet capacity that balances ample storage and fuel efficiency. Unlike the soft-sided FIVKLEMNZ bag, it offers a more streamlined profile, reducing wind noise and drag during highway driving. Its dual-side opening makes access convenient from either side of the vehicle, while the lockable design enhances security. Installation is straightforward, but some users might find roof rack compatibility checks necessary beforehand. Its sturdy ABS construction withstands the elements, but rigidity means less flexibility for oddly shaped items. This model suits those who want a reliable, secure, and aerodynamic carrier for family trips but may be less appealing for drivers prioritizing maximum capacity or soft-sided flexibility.
Pros:- Secure locking system with two keys for added safety
- Aerodynamic design reduces wind noise and improves fuel efficiency
- Dual-side opening provides easy access from either side
- Easy installation with all necessary components
Cons:- Roof rack compatibility should be verified before purchase
- Installation can be challenging for some users
- Rigid structure offers less flexibility for irregularly shaped items

- Opening:Dual-side
Our verdict“This hard-shell carrier is ideal for those needing a secure, low-drag option with reliable weatherproofing for family or long-distance trips.”
DNA Motoring Rooftop Cargo Box Carrier, 11 Cubic Feet, 53″L x 34″W x 15″H, Lockable, Heavy Duty, Glossy Black
Compared with larger options like the FIVKLEMNZ bag, this 11-cubic-foot box offers a streamlined solution for those with limited roof space or seeking quick setup. Its impact-resistant ABS plastic ensures durability for moderate weather conditions, but it lacks explicit waterproofing details, making it less suitable for heavy rain without additional protection. The lockable lid adds security, but the need for cross bars limits compatibility to vehicles equipped with them. This model fits well on smaller SUVs or sedans with cross bars, prioritizing security and ease of installation over maximum capacity. It’s a practical choice for owners who want a simple, secure, and durable cargo box without the bulk of larger models.
Pros:- Durable impact-resistant construction for everyday use
- Lockable lid enhances security
- Easy to install without tools on vehicles with cross bars
- Sleek glossy black finish
Cons:- Requires cross bars for mounting, limiting compatibility
- Limited capacity compared to larger soft or hard-shell options
- Unclear weatherproofing features
Best for: Owners of vehicles with cross bars needing a secure, durable, and manageable cargo solution
Not ideal for: Drivers without cross bars or those requiring large capacity or full weatherproofing for extended outdoor use
- Capacity:11 cubic feet
- Dimensions:53″ L x 34″ W x 15″ H
- Material:ABS plastic
- Lockable:Yes
Our verdict“This compact, lockable box fits well on vehicles with cross bars, offering a durable and straightforward storage option for shorter trips.”
Garvee Rooftop Cargo Box Carrier, 11.5 Cubic Feet, Dual-Side Opening, Black
Designed for durability, the Garvee cargo box offers 11.5 cubic feet of waterproof, UV-resistant storage that resists fading and weather damage. Its dual-side opening makes access convenient, especially for vehicles with limited space around the car. Compared to the larger soft-sided options like FIVKLEMNZ, it provides a rigid, secure environment for your gear, although its capacity is slightly smaller. The inclusion of secure straps and keys adds peace of mind, but compatibility with roof racks must be verified, as it is limited to vehicles equipped with racks. This pick is better suited to those who prioritize weatherproofing and ease of access, yet it might fall short for travelers needing maximum volume or soft-sided flexibility.
Pros:- Waterproof and UV-resistant construction prolongs lifespan
- Large 11.5 cubic feet capacity for gear and travel essentials
- Dual-sided opening simplifies access
- Includes secure straps and keys for safety
Cons:- Compatibility depends on roof rack presence
- Limited to vehicle types with roof racks
- Slightly smaller capacity than some soft-sided options
Best for: Drivers requiring a durable, waterproof hard shell carrier that’s easy to access and secure
Not ideal for: Those without a roof rack or needing maximum cargo capacity for multi-week trips
- Material:ABS
- Capacity:11.5 cubic feet
- Dimensions:54.3″L x 31.5″W x 11.4″H
- Color:Black
Our verdict“This waterproof hard shell carrier is perfect for travelers prioritizing weather resistance and security on vehicles with roof racks.”
Car Rooftop Cargo Carrier Bag, 21 Cubic Feet, Waterproof, Heavy Duty 840D Car Roof Bag for All Vehicles with/without Racks
This soft, waterproof cargo bag matches the capacity of the FIVKLEMNZ model but excels in adaptability, fitting on any vehicle with or without roof racks. Its heavy-duty 840D fabric ensures durability in harsh weather, but the bulkiness can be a drawback when storing or handling, especially when not fully loaded. The reinforced seams and waterproof zippers provide confidence in adverse conditions, yet proper installation is key to prevent shifting during transit. It’s an excellent choice for those seeking maximum capacity without the rigidity of a hard shell, though it requires careful securing and may be less aerodynamic. This bag is best for versatile, weatherproof storage on a variety of vehicle types, especially when ease of use and capacity are priorities.
Pros:- Heavy-duty waterproof fabric withstands harsh weather
- Large capacity suitable for extended trips
- Adjustable straps and included accessories facilitate secure installation
- Universal fit for all vehicle types
Cons:- Bulky when not in use or partially loaded
- Installation requires attention to prevent shifting
- Heavy fabric may be cumbersome to handle
Best for: Travelers needing large, flexible, waterproof storage that fits all vehicle types regardless of roof rack presence
Not ideal for: Drivers seeking a lightweight, low-profile carrier for occasional use or minimal gear
- Capacity:21 cubic feet
- Material:840D PVC fabric
- Waterproof:Yes
- Includes:Anti-slip mat, straps, door hooks, luggage lock
Our verdict“This heavy-duty, waterproof roof bag offers flexible capacity and universal fit, ideal for travelers demanding weatherproof durability and large volume.”
Asinking Car Rooftop Cargo Carrier Bag 21 Cubic Feet Waterproof Car Roof Top Bag for All Cars with/Without Rack, Includes Anti-Slip Mat, 10 Reinforced Straps, 6 Door Hooks, Luggage Lock
This soft-shell carrier stands out for its large 21 cubic feet capacity and adaptability to all vehicle types, whether equipped with racks or not. Its waterproof, durable 900D PVC tarpaulin makes it a strong choice for unpredictable weather, unlike rigid alternatives such as the SportRack Vista XL, which offers easier access but less weather resistance. While the Asinking bag provides security with a lock and reinforced straps, its soft design may be less rigid for bulky or heavy items, and installation can be tricky for first-timers. Compared to hard-shell options, it’s more flexible but potentially less secure against theft if the lock is compromised. It makes the most sense for road trippers needing maximum capacity with weatherproof confidence, especially in variable climates.
Pros:- Waterproof and tearproof construction for all weather conditions
- Universal fit for cars with or without roof racks
- Includes security features like locks and reinforced straps
- Large capacity for multi-person luggage
Cons:- Soft shell may be less rigid for heavy or bulky items
- Installation can be challenging initially
- Limited security if lock is compromised
Best for: Travelers seeking a weatherproof, high-capacity soft carrier that fits all vehicle types without racks
Not ideal for: Drivers prioritizing rigid, rigid security features or quick, tool-free mounting on specific rack systems
- Capacity:21 cubic feet
- Dimensions:52” (L) x 40” (W) x 18” (H)
- Material:900D PVC tarpaulin
- Includes:Anti-slip mat, luggage lock, 6 security hooks, storage bag
Our verdict“This carrier is ideal for road trippers needing flexible, weatherproof storage with high capacity and universal fit.”
Yakima SkyBox NX 18 Roof Top Cargo Carrier, 18 Cubic Feet, Black
The Yakima SkyBox NX 18 is a solid choice for those valuing security and ease of access, with its dual-sided opening and full lockable handle. Its 18 cubic feet capacity rivals the SportRack Vista XL, but with the advantage of easier, more convenient access from either side, which is a plus during quick stops. The lockable handle enhances security, though the overall weight can make installation more strenuous without assistance, especially compared to lighter soft options like the Sailnovo Rooftop Cargo Carrier. Its sleek black finish makes it less conspicuous, ideal for those who want a discreet yet secure cargo solution. Perfect for outdoor enthusiasts carrying skis or gear up to 195cm, but less suited for bulky, heavy luggage due to handling weight.
Pros:- Secure locking system enhances cargo safety
- Dual-sided opening for easy access from either side
- Unobstructed interior maximizes usable space
- Suitable for skis up to 195cm
Cons:- Heavy to handle and install alone
- Limited color options (only black)
Best for: Active travelers needing secure, dual-access storage for skis, snowboards, or camping gear
Not ideal for: Users seeking a lightweight, easy-to-install option for occasional use or larger bulky luggage
- Capacity:18 cubic feet
- Color:Black
- Fits skis up to:195cm
- Opening:Dual-sided
- Locking mechanism:Full metal handle with locks
Our verdict“This roof box is best for adventure seekers who need secure, easy access to gear during outdoor trips.”
Sailnovo Rooftop Cargo Carrier, 21 Cubic Feet Waterproof Soft-Shell Roof Bag for Vehicles
The Sailnovo Rooftop Cargo Carrier offers a generous 21 cubic feet of waterproof storage, making it an excellent choice for extended trips or camping, especially compared with smaller hard-shell options like the DNA Motoring Carrier. Its tearproof PVC fabric and reinforced straps ensure durability in harsh weather, while its foldable design allows easy storage when not in use. However, it’s not suitable for vehicles with sliding doors or very small cars that may have overhang issues. The multiple straps and hooks provide security but require proper installation to prevent water pooling or shifting mid-drive. This carrier is perfect for budget-conscious travelers needing flexible, weatherproof capacity without the rigidity of hard shells.

Our verdict“This soft carrier is perfect for travelers who need large, waterproof storage that’s budget-friendly and easy to store.”
Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cubic Feet, Waterproof, Fits Cars with/Without Rack
The Sailnovo Roof Bag offers 20 cubic feet of waterproof storage with a sturdy build from tear-resistant 1000D Oxford cloth. Its 20 cubic feet capacity is close to the larger soft options and makes it suitable for camping or road trips, especially compared with the smaller DNA Motoring Carrier. Its foldable design provides convenience for storage, and the included straps and hooks help ensure a secure fit on most roof types. However, it’s less ideal for vehicles with sunroofs or very small cars where overhang could be an issue.

Our verdict“This roof bag offers a reliable waterproof solution for moderate-capacity needs across various vehicle types.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL offers an 18 cubic foot capacity with a durable UV-resistant ABS shell, making it a strong candidate for those prioritizing easy rear access, especially compared to soft-sided options like the Sailnovo Carrier. Its tool-free installation and secure mounting make it a practical choice for frequent travelers, though it may require checking compatibility with your specific rack system, unlike universal soft bags. Its UV-resistant material helps it withstand sun exposure, but the rigid shell can be less forgiving in tight spaces or on smaller vehicles, where overhang might be a concern. With a maximum weight capacity of 100 pounds, it suits heavier gear but limits overloading.
Pros:- Large 18 cubic feet capacity for bulky luggage
- UV-resistant, durable ABS material
- Rear opening for convenient access

Cons:- Requires checking rack compatibility
- Limited flexibility compared to soft bags
- Maximum weight capacity of 100 pounds

- Dimensions:63 x 38 x 19 in / 160 x 96.5 x 48 cm
- Max Weight Capacity:100 pounds (45 kg)

How We Picked
The products in this roundup were evaluated based on capacity, durability, ease of installation, weather resistance, and overall value. I prioritized options with strong build quality and user-friendly features, such as dual-side access or lockable lids. The ranking reflects a balance between affordability and performance, aiming to match different types of road trip needs—from casual weekend getaways to extended family adventures. Products with proven reliability, positive customer feedback, and safety features were weighted more heavily to ensure they meet the demands of frequent travel.Factors to Consider When Choosing Roofcargo Box For Road Trips
Choosing the right roofcargo box for road trips involves considering multiple factors that impact convenience, safety, and longevity. Beyond simply comparing capacity or price, understanding how the design, materials, and features align with your specific travel needs can save money and frustration. This guide highlights key considerations to help you make an informed decision that enhances your road trip experience.Capacity and Size
Determining the right capacity depends on the size of your vehicle and the amount of gear you plan to carry. Larger boxes up to 21 cubic feet provide ample space for families or long trips, but they can also add wind resistance, reducing fuel efficiency. Smaller options around 11-15 cubic feet are more manageable and easier to mount, though they may limit what you can pack. Consider your vehicle’s roof dimensions and storage needs to pick a size that balances space with practicality.
Material and Durability
Hard-shell cargo boxes typically use ABS plastic or fiberglass, offering better protection and aerodynamics. Soft bags, like waterproof roof carriers, are lighter and more flexible but may not withstand severe weather or impacts as well. Think about the climate and terrain of your trips—if rain or snow are common, investing in a waterproof hard-shell model makes more sense. Durability also involves locking mechanisms and UV-resistant materials that prevent fading and wear over time.
Ease of Installation and Access
Quick, secure installation is essential—look for models with universal mounts that fit most roof rails. Dual-side opening features allow easier access when parked, saving time during stops. Some models come with lockable lids, adding security for valuables. Keep in mind that heavier hard-shell boxes may require two people to install safely, so consider your physical comfort and frequency of use when choosing.
Weatherproofing and Security
Protection from the elements is non-negotiable for road trips, especially in unpredictable weather. Waterproof seals, heavy-duty zippers, and UV-resistant shells are signs of a reliable cargo box. Security features like locks prevent theft when parked. Soft bags should have sealed seams and waterproof fabric, but they may be less effective in heavy storms compared to rigid models. Evaluate your typical travel weather to determine the level of protection needed.
Price and Value
Budget options often sacrifice some durability or ease of access, but many soft bags offer excellent waterproofing at lower prices. Hard-shell boxes tend to cost more but provide better protection and aerodynamic benefits, which can improve fuel economy. Consider how often you’ll use the box—if it’s a once-in-a-while accessory, a less expensive model might suffice. For frequent travelers or long-term use, investing in a higher-quality, durable model can deliver better value over time.
Frequently Asked Questions
Will a roofcargo box fit on my vehicle’s roof?
Most roofcargo boxes are designed to fit a wide range of vehicles with standard roof rails or crossbars. However, it’s important to check the specific dimensions and mounting requirements of the model against your vehicle’s roof. Some models come with adjustable mounting systems to accommodate different rail sizes. If your vehicle lacks roof rails, you may need additional mounting accessories, which can increase complexity and cost.
How secure is a roofcargo box against theft?
Many roofcargo boxes include lockable lids, providing a significant deterrent against theft. Choosing a model with a high-quality locking mechanism adds peace of mind, especially for long stops or overnight parking. Keep in mind that no lock is completely theft-proof, so combining security features with parking in safe areas is advisable. Soft bags often lack locking features, making them less secure, though they are easier to carry when not mounted.
Does a roofcargo box impact fuel efficiency?
Yes, adding a roofcargo box increases aerodynamic drag, which can lead to higher fuel consumption. Hard-shell models with streamlined designs tend to produce less drag than bulky or soft options. If fuel economy is a priority, opt for a compact, aerodynamic box and remove it when not in use. Consider the tradeoff between extra storage capacity and additional fuel costs, especially on long trips.
What’s the best way to maintain a roofcargo box?
Regular cleaning with mild soap and water helps maintain the appearance and waterproofing of your roofcargo box. Check seals and locks periodically for signs of wear or damage, and lubricate locking mechanisms to keep them functioning smoothly. For soft bags, ensure seams and zippers remain waterproof—reapply waterproof spray if necessary. Proper maintenance extends the lifespan and keeps your gear protected during every trip.
Are roofcargo boxes easy to remove and store?
Most hard-shell cargo boxes are designed for straightforward mounting and removal, often requiring just a few minutes with the right tools. Lighter soft bags are even easier to detach and fold or roll for storage when not in use. Consider your storage space at home—if space is limited, lightweight models or soft bags could be more practical. Always ensure the box is securely fastened during travel to prevent accidents or damage.
