More Details on Our Top Picks
Car Roof Bag Waterproof 21 Cubic Feet Rooftop Cargo Carrier
This roof bag stands out for its generous 21 cubic feet capacity combined with a fully waterproof, tearproof exterior, making it a top choice for travelers needing reliable protection and ample space. Unlike the FIVKLEMNZ carrier, which emphasizes heavy-duty durability with 840D fabric, this option offers a more balanced approach with compatibility for vehicles with or without racks and includes safety features like a combination lock. The main tradeoff is its zipper, which requires careful handling to maintain waterproof integrity—something less critical in softer bags like the RoofPax. Installation can be challenging for some, but its comprehensive features make it a versatile pick.
Pros:- Large 21 cubic feet storage capacity for multiple luggage items
- 100% waterproof with tearproof 800D PVC material

FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
Compared to the Car Roof Bag, the FIVKLEMNZ carrier offers similar capacity at 21 cubic feet but emphasizes durability with heavy-duty 840D PVC, making it more resistant to wear. It includes a full travel kit—anti-slip mat, reinforced straps, door hooks—that simplifies installation and enhances security. However, its larger size (52 x 40 x 18 inches) might not fit smaller vehicles comfortably, and securing multiple straps can be time-consuming. Still, its focus on waterproofing and comprehensive accessories makes it an appealing choice for budget-conscious users seeking reliable outdoor gear.
Pros:- Heavy-duty 840D waterproof PVC material ensures dryness in all weather
- Large capacity suitable for multiple suitcases and outdoor gear
- Includes a full travel kit for straightforward installation

MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti Slip Mat and Racks
This 20-cubic-foot carrier emphasizes straightforward mounting with multiple straps and an easy-to-attach design, making it suitable for users who prioritize quick setup and flexible fitting. Its PVC construction provides reliable waterproofing, comparable to the FIVKLEMNZ but with a slightly smaller capacity. Its malleable design can adapt to different roof shapes, unlike rigid hard-shell carriers, yet it might be less durable over time and could be less resistant to tearing or heavy abrasion. Its flexible mounting system is perfect for long trips requiring frequent setup and takedown.
Pros:- Large 20 cubic feet capacity for extra cargo space
- PVC material provides waterproof protection
- Easy to mount and store thanks to flexible design
- Includes anti-slip mat and multiple straps for secure fastening
Cons:- May be less durable than hard-shell options

- Design may not fit all roof sizes precisely
Best for: Travelers who want an easy-to-install, waterproof option that fits a variety of vehicle types and roof shapes
Not ideal for: Heavy-duty users seeking maximum durability or those with very small or very large vehicles where fit might be off
- Capacity:20 cubic feet
- Dimensions:51.1” x 39” x 17”
- Material:PVC
- Includes:Anti slip mat, 6 straps, 2 3M straps
Our verdict“This carrier suits users needing quick, flexible installation with reliable waterproofing for moderate to long trips.”
Car Rooftop Cargo Carrier Bag, 21 Cubic Feet, Waterproof, Heavy Duty 840D
Compared to lighter options like the Car Roof Bag, this 21-cubic-foot carrier offers superior durability thanks to its 840D abrasion-resistant PVC fabric, making it a strong choice for harsh weather conditions. Its heavy-duty build and reinforced seams promise longevity, but this also makes the bag bulkier and heavier, which could complicate storage or handling during installation. While it offers a straightforward setup with adjustable straps and secure fittings, its lack of detailed dimensions might pose a challenge for precise fit, particularly on smaller roofs. This pick is ideal for users who prioritize ruggedness and longevity over weight or ease of storage.
Pros:- Heavy-duty 840D PVC fabric ensures durability in all weather
- Reinforced seams prevent tearing
- Large capacity fits multiple luggage items
- Easy to install with adjustable straps and secure fittings
Cons:- Bulky and heavier than softer bags
- Lack of exact dimensions may cause fit issues
Best for: Active travelers requiring a highly durable, weatherproof carrier for frequent outdoor use
Not ideal for: Casual users or those with limited storage space who need a lightweight, easily stowed option
- Capacity:21 cubic feet
- Material:840D abrasion-resistant PVC
- Waterproof:Yes
- Includes:Anti-slip mat, 6 door hooks, storage bags, 2 straps, luggage lock
Our verdict“Best suited for users seeking maximum durability and weather protection in an outdoor or rugged environment.”
RoofPax 23 cu ft Waterproof Rooftop Cargo Carrier Bag with Double Zippers and Tie-Down Straps
The RoofPax 23 cu ft carrier emphasizes security with patented door hook straps and double waterproof zippers, making it ideal for users who prioritize weatherproofing and safety. Its military-grade materials and water-repellent coating outperform many standard soft bags like the MIDABAO, especially in heavy rain or snow. The larger capacity of 23 cubic feet makes it suitable for extensive luggage needs. While its weight and bulk may require careful installation, the extensive set of straps and hooks compensate for potential fit issues, especially on vehicles without roof racks. This makes it a strong choice for critical weather conditions and maximum security.
Pros:- Maximizes safety with patented door hook straps
- Highly waterproof with double zippers and water-repellent coating
- Largest capacity at 23 cubic feet
- Includes comprehensive straps and accessories for secure installation
Cons:- Proper installation is essential for security
- Heavy and bulky, which may be challenging for some vehicles
Best for: Travelers needing the highest level of weather protection and safety for long trips in adverse conditions
Not ideal for: Owners of small or low-clearance vehicles where bulky, heavy bags could be difficult to manage
- Capacity:23 cubic feet
- Material:Military-grade materials
- Waterproof:Yes
- Includes:Door hook straps, connection straps, storage bag
- Warranty:Lifetime on zippers, 5-year on fabric
Our verdict“This bag is ideal for users needing maximum weatherproof security and capacity for extended outdoor adventures.”
Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cuft, Fits Most Cars with/Without Rack
This option stands out for offering a generous 20 cubic feet of storage at an accessible price, making it ideal for families needing extra space without paying for rigid hard-shell carriers. Compared with the TANX or WORKPRO, it provides similar capacity but slightly lighter construction, which can be a double-edged sword—less rigidity might mean less stability in high winds or extreme weather. This bag is made from tear-resistant, water-repellent Oxford cloth, ensuring durability for typical outdoor trips. Its ease of attachment with included straps makes it suitable for quick setups, and it folds compactly when not in use. However, it’s not recommended for vehicles with sunroofs or very small cars, as overhang or fit issues could occur. Proper filling is key to preventing water pooling, and overstuffing may compromise water resistance.
Pros:- Large 20 cubic feet capacity for ample storage
- Durable tear-resistant and water-repellent material
- Folds into a compact size for easy storage
Cons:- Not recommended for vehicles with sunroofs
- May overhang on very small cars
- Requires proper filling to prevent water pooling
Best for: Budget-conscious families or outdoor enthusiasts seeking large capacity and easy storage.
Not ideal for: Vehicles with sunroofs or small cars where overhang might cause fitment issues.
- Capacity:20 cubic feet
- Dimensions:51″ (L) x 39″ (W) x 17″ (H)
- Material:1000D Oxford cloth
- Includes:6 tie-down straps, 6 safety hooks
Our verdict“This roof bag offers an excellent balance of capacity and affordability for casual outdoor users with standard vehicles.”
TANX Car Roof Bag – 21 Cubic Feet Waterproof Rooftop Cargo Carrier with Straps and Lock
The TANX Car Roof Bag makes a strong impression for its 21 cubic feet of waterproof storage, perfect for outdoor adventurers prioritizing dryness and security. Compared with the WORKPRO or Asinking, it emphasizes waterproofing with a 700D PVC tarpaulin and grid material, which can be more resistant to heavy rain but might be slightly less flexible in extreme cold. Its included lock and anti-slip mat add peace of mind during transit, especially on busy highways. The soft-shell design provides flexibility, but this can mean less rigidity in high winds or when heavily loaded, potentially affecting stability. Installation requires careful setup to prevent shifting, and some users report difficulty in securing it tightly. It is best suited for those who need waterproof security over rigid stability.
Pros:- Large 21 cubic feet capacity for versatile storage
- 100% waterproof material with lock and anti-slip mat
- Universal fit with included straps and hooks
Cons:- Soft-shell may be less rigid in extreme conditions
- Requires careful installation to avoid shifting
- Customer reviews mention setup difficulties
Best for: Outdoor enthusiasts or families needing waterproof protection and security during long trips.
Not ideal for: Drivers who prioritize rigid stability in high-speed conditions or who want a more rigid carrier for extreme weather.
- Capacity:21 cubic feet
- Material:700D PVC tarpaulin and grid
- Dimensions:51″ L x 40″ W x 17″ H
- Includes:Anti-slip mat, 12 straps, 6 door hooks, lock, storage bag
Our verdict“Best suited for users who need maximum waterproof protection combined with secure locking features without sacrificing flexibility.”
WORKPRO Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Car Roof Bag
The WORKPRO carrier is a reliable choice for those needing a sizable 21 cubic feet of waterproof storage, with an emphasis on safety and ease of use. Its reinforced straps and reflective strips improve security and visibility, making it suitable for outdoor trips with unpredictable weather. Compared to the TANX, it offers similar capacity but adds safety features that make it more appealing for family use or longer drives. The durable 840D PVC material is designed to withstand weather elements, but soft carriers inherently lack the rigidity of hard-shell options, which could be a concern in high winds or heavy snow. Its straightforward installation process suits users who prefer a hassle-free setup but may not be as customizable as some competitors.
Pros:- Large 21 cubic feet storage capacity
- Weather-resistant and durable 840D PVC fabric
- Includes safety features like reflective strips
Cons:- Less rigid than hard-shell options
- Waterproof performance may suffer under extreme conditions
- Installation can be challenging for some users
Best for: Families or travelers prioritizing safety, durability, and straightforward setup for outdoor adventures.
Not ideal for: Those seeking a highly rigid carrier or who often drive in extreme wind conditions.
- Capacity:21 cubic feet
- Material:840D PVC
- Dimensions:52″x40″x17″
- Number of straps:10 reinforced straps
Our verdict“This carrier balances safety features and capacity, making it ideal for cautious travelers seeking durability.”
Car Rooftop Cargo Carrier Bag, 15 Cubic Feet Waterproof Heavy Duty 840D Car Roof Bag for All Vehicles with/Without Racks
This carrier, with 15 cubic feet of capacity, emphasizes rugged durability thanks to its 840D abrasion-resistant PVC fabric. It’s a suitable choice for users who need a tough, weather-resistant bag for smaller loads or occasional use. Compared with larger options like the TANX or WORKPRO, it provides less volume but offers increased durability, especially in rough conditions. Its heavy-duty material can be stiff, making it less flexible during installation. Waterproof zippers and reinforced seams enhance its reliability, but the somewhat limited capacity and undefined dimensions mean it’s best for those with lighter, smaller cargo needs. It’s not the best choice for large family trips but excels in demanding environments.
Pros:- Heavy-duty abrasion-resistant 840D PVC fabric
- Weatherproof with sealed seams and waterproof zippers
- Reliable for demanding environments
Cons:- Limited capacity at 15 cubic feet
- Stiff material can complicate installation
- Dimensions not specified, may not suit all vehicle sizes
Best for: Outdoor workers or travelers with smaller loads needing a tough, weatherproof carrier.
Not ideal for: Large families or those needing maximum cargo space, due to its limited volume.
- Capacity:15 cubic feet
- Material:840D PVC
- Waterproof:Yes
- Warranty:2 years
Our verdict“Best suited for users requiring a highly durable, weatherproof carrier for smaller loads or rugged use.”
Asinking Car Rooftop Cargo Carrier Bag, 20 Cubic Feet, Waterproof, Universal Fit with Accessories
The Asinking carrier combines a large 20 cubic feet capacity with a comprehensive set of accessories, making it a strong contender for versatile outdoor needs. Its 900D double-coated PVC laminated tarpaulin offers excellent waterproofing, comparable to the TANX, but with a slightly more aerodynamic design that reduces wind noise and drag—advantageous for longer drives. It’s compatible with vehicles with or without racks and comes with a non-slip mat, door hooks, and a lock, providing added security and ease of installation. However, the installation process might be tricky for some, especially without prior experience, and its weight can be an issue for those lifting it onto the roof. Still, it’s a well-rounded choice for a broad range of users.
Pros:- Large 20 cubic feet capacity for versatile use
- Highly waterproof with 900D double-coated PVC
- Includes multiple accessories for secure and easy installation
Cons:- Installation can be challenging for some users

- Material:900D PVC laminated tarpaulin
- Dimensions:40 L x 52 W inches
Our verdict“Ideal for users wanting a spacious, waterproof carrier with added security features and accessories for long trips.”
FIVKLEMNZ 30 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
This model stands out for its generous 30 cubic feet of waterproof space, making it ideal for lengthy road trips or large family vacations. Compared with the 28 cu ft RoofPax XXL, it offers slightly more volume, but the heavier weight and potentially more complex installation can be a tradeoff. Its high-frequency welded seams and durable 840D PVC ensure reliable waterproofing, and the included travel kit simplifies setup. However, the large size may make it cumbersome to handle and install, especially on smaller vehicles. This pick makes the most sense for those prioritizing maximum storage and a comprehensive setup, willing to manage the weight and installation effort.
Pros:- Largest capacity among soft-shell options at 30 cubic feet
- 100% waterproof with durable materials and welded seams
- Includes a full travel kit for easier installation

- Capacity:30 cubic feet
- Dimensions:60 x 43 x 20 inches
- Material:840D PVC
- Seams:High-frequency welded
- Includes:Anti-slip mat, luggage lock, reinforced straps, door hooks, storage bag
Our verdict“This is best for those who need maximum cargo space and don’t mind handling a heavier, more complex setup.”
Asinking Car Rooftop Cargo Carrier Bag 21 Cubic Feet Waterproof Roof Top Bag for All Cars with/Without Rack, Includes Anti-Slip Mat, Reinforced Straps, Door Hooks, and Lock
This 21 cu ft soft shell cargo bag offers a balanced option for those needing waterproof storage without the bulk of larger models like the FIVKLEMNZ. It’s compatible with vehicles both with and without roof racks, similar to the RoofPax XXL, but with less capacity, making it more manageable for everyday use. Its 900D PVC tarpaulin provides solid waterproofing, but the soft shell design may be less rigid under very heavy loads, and securing it properly is critical to prevent movement. While it lacks specific UV resistance info, its universal fit and included security features make it a flexible choice for most drivers. It’s ideal for moderate trips where ease of handling matters more than maximum volume.
Pros:- Durable, tearproof 900D PVC construction
- Universal fit for vehicles with or without roof racks
- Includes security features like locks and hooks
- Easier to handle due to moderate size
Cons:- Soft shell design offers less rigidity for very heavy items

Not ideal for: Owners of large families or those needing maximum storage capacity for extended travel
- 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 bag strikes a good balance for casual or frequent travelers who prioritize flexibility and waterproofing over maximum capacity.”
RoofPax XXL 28 cu ft Car Rooftop Cargo Carrier Bag with Waterproof Design and Heavy Duty Tie Down Straps
Compared to the FIVKLEMNZ 30, the RoofPax XXL offers slightly less capacity but emphasizes secure mounting and weather resistance. Its 28 cu ft volume makes it suitable for larger vehicles like SUVs, and the inclusion of heavy-duty straps, hooks, and a lock enhances security during travel. Its waterproof fabric and lifetime on zippers and buckles demonstrate long-term durability. However, its bulkiness can challenge smaller cars, and proper installation is essential to prevent safety issues. This pick makes the most sense for those needing a large, weather-resistant carrier with a focus on security and durability, especially on bigger vehicles.
Pros:- Large 28 cubic feet capacity for ample gear
- Weather-resistant fabric suitable for all seasons
- Heavy-duty straps and locks for security
- Compatible with vehicles with or without roof racks
Cons:- Bulky to install on smaller or lower-profile vehicles
- Requires careful securing for safe travel

- Warranty:Lifetime on zippers and buckles, 5-year on fabric
Our verdict“This is ideal for users who want a secure, weatherproof cargo carrier for larger vehicles with frequent, heavy use.”
FIVKLEMNZ Car Rooftop Cargo Carrier Waterproof Roof Bag with Accessories
The FIVKLEMNZ 15 cu ft roof bag is perfect for drivers needing additional space without the bulk of larger models. Its compact size and lightweight design make it easier to install and remove, comparable to the Asinking 20 cu ft bag, but with less capacity. Made from durable 840D PVC with welded seams, it offers strong waterproof protection for shorter trips or minimal gear. Its universal fit ensures compatibility with most vehicles, including those without roof racks, but careful securing is needed to prevent movement in windy conditions. This pick is suited for occasional travelers or those with limited roof space, prioritizing convenience over maximum volume.

- Highly waterproof with welded seams
- Universal fit for various vehicle types
- Good for short trips or minimal gear

- Capacity:15 cubic feet
- Dimensions:46 x 34 x 17 inches

Our verdict“This is a smart choice for infrequent travelers or those with limited roof space who want quick, reliable waterproof storage.”

How We Picked
The products in this roundup were evaluated based on a combination of capacity, waterproofing performance, material quality, ease of installation, and added features. We prioritized models that offered reliable waterproof protection and ease of use across different vehicle types, especially those that are compatible without racks. Price was considered in relation to durability and capacity, ensuring options for different budgets. The ranking reflects a balance between value and performance, highlighting models that excel in everyday use while acknowledging tradeoffs like weight or complexity of setup.Factors to Consider When Choosing Roof Cargo Carriers Soft Shell
Choosing the right soft shell roof cargo carrier involves understanding several key factors that affect performance and convenience. Beyond just capacity, consider how waterproofing holds up in heavy rain, how easy it is to install and remove, and whether the size fits your vehicle without obstructing visibility or access. Evaluating material quality can prevent early wear and tear, especially if you plan to use the carrier frequently. Additional features such as locks or anti-slip mats can improve security and stability but may add to the cost. Being aware of these broader considerations helps prevent common mistakes like oversizing or underestimating waterproof performance.Capacity and Size Compatibility
Ensuring the carrier’s capacity matches your load needs is crucial. Larger capacities, like 28-30 cubic feet, are suited for family trips or longer travel, but they also add weight and can be more challenging to install. Smaller options may suffice for quick trips or minimal gear. Always measure your vehicle’s roof and check the carrier’s dimensions to avoid obstructing windows or access points. Keep in mind that larger carriers may require additional tie-downs or racks for secure attachment, especially on vehicles without existing roof rails.
Waterproofing and Material Durability
Since soft shell carriers are exposed to the elements, waterproof performance is vital. Look for models with reinforced fabrics like 840D polyester or those with sealed seams and double zippers. Cheaper materials may leak or degrade quickly, especially after exposure to UV rays or heavy rain. Consider whether the fabric is UV-resistant and how well it resists tearing or abrasions. Investing in a slightly more expensive, high-quality material can extend the lifespan of your carrier and protect your gear better.
Ease of Installation and Removal
A carrier that’s simple to set up and take down saves time and reduces frustration, particularly if you need to access your gear mid-trip. Features like quick-release straps, integrated handles, and clear instructions make a difference. If you frequently switch between vehicles or need to remove the carrier for storage, lightweight and foldable models will be more convenient. Be mindful of compatibility with your vehicle’s roof type—some carriers work better with crossbars or racks, while others are designed for direct attachment to the car’s roof or door hooks.
Additional Security and Stability Features
Security features like lockable zippers or reinforced straps help prevent theft and ensure the carrier stays attached in windy conditions. Anti-slip mats can improve stability during driving, especially on slick or uneven surfaces. Tie-down straps with reinforced loops offer extra security, but they can complicate installation if they’re not intuitive. Weigh the importance of these features against potential added cost and complexity—sometimes a basic carrier with good straps is sufficient for casual use.
Price versus Long-Term Value
While budget carriers may seem appealing, they often compromise on waterproofing, material strength, or ease of use. Investing a bit more upfront can result in a product that lasts several seasons, saving money in the long run. Look for warranties or guarantees that indicate manufacturer confidence. Remember that features like reinforced seams, heavy-duty fabrics, and secure locking systems tend to increase initial cost but provide better protection and durability over time.
Frequently Asked Questions
Will a soft shell roof cargo carrier fit on my vehicle without racks?
Many soft shell carriers are designed to attach directly to the vehicle’s door hooks or use straps that go around the roof. It’s important to check the product specifications for compatibility with vehicles without racks. Some models include universal straps and hooks that fit most cars, but their effectiveness depends on your roof’s shape and whether your car has door frame points or crossbars. Always verify measurements and attachment methods before purchasing to avoid a mismatch that could lead to instability or damage.
How weatherproof are these soft shell cargo bags in heavy rain or snow?
Most quality soft shell carriers are made from waterproof or water-resistant fabrics with sealed seams and double zippers to prevent leaks. However, no soft shell bag is completely waterproof under extreme conditions, especially if it’s exposed to prolonged heavy rain or snow. It’s advisable to choose models with reinforced, UV-resistant materials for better longevity. Additionally, using an extra rain cover or ensuring tight closures can help protect your gear from the elements more effectively.
Are soft shell roof cargo carriers secure enough to prevent theft?
While soft shell carriers are more vulnerable to theft compared to hard cases, many models feature lockable zippers or straps that can be secured with padlocks. Reinforced fabrics and tamper-resistant attachment points add a layer of security. For high-value gear or long trips, it’s wise to combine the carrier with additional security measures like lockable straps or anti-theft devices. Remember, no soft shell carrier is completely theft-proof, so consider your environment and risk factors when leaving it unattended.
Can I leave my soft shell carrier on the car during rain or snow overnight?
Yes, most soft shell carriers are designed to withstand exposure to weather when properly installed. However, prolonged exposure to harsh weather, especially snow or freezing rain, can compromise the fabric over time. It’s best to remove the carrier when not in use for extended periods or during severe weather to prolong its lifespan. If leaving it on, ensure all closures are secure, and consider covering it with an additional waterproof cover for extra protection.
How do I maintain and clean my soft shell roof cargo carrier?
Cleaning typically involves rinsing with water and mild soap, avoiding harsh chemicals that could degrade the fabric or waterproof coating. Regular inspections for tears, seam integrity, and secure straps help maintain safety and performance. Allow it to dry fully before storing to prevent mold or mildew. When not in use, fold it into a compact size and store it in a cool, dry place to avoid unnecessary wear. Proper maintenance extends the life of your carrier and keeps it ready for your next trip.
