More Details on Our Top Picks
Mockins 40 CuFt XXL Car Roof Bag 72″x48″x20″ Soft-Shell Waterproof Roof Cargo Carrier
This roof bag stands out for its massive 40 cubic feet capacity, making it ideal for extended trips or moving large amounts of gear. Compared with smaller options like the DUMOS 15 cu ft, it offers significantly more space, though it comes with added weight and complexity in securing. Its waterproof and abrasion-resistant 840D vinyl ensures cargo stays dry, even in heavy rain, but the soft-shell design means it lacks the rigidity of hard cases, which could impact protection of fragile items. Installation requires attention to secure straps properly, but the included accessories simplify setup. This pick is perfect for those needing maximum storage without sacrificing vehicle compatibility, especially on long journeys or when hauling bulky gear.
Pros:- Massive 40 cu ft capacity for extensive storage needs
- Waterproof and abrasion-resistant for durability
- Includes comprehensive straps, hooks, and accessories for easy installation
Cons:- Requires careful installation to ensure security
- Heavy when fully loaded, which may affect handling
Best for: Travelers with large loads or families needing extensive cargo space for road trips or moving.
Not ideal for: Urban commuters with limited roof space or those prioritizing quick, hassle-free setup due to the larger, heavier bag.
- Capacity:40 cu ft
- Dimensions:72″x48″x20″
- Material:840D vinyl
- Warranty:10 years
Our verdict“Best suited for users needing maximum cargo capacity and willing to manage a larger, heavier roof bag for long-distance trips.”
DUMOS Car Roof Bag Cargo Carrier Waterproof 15 Cubic Feet for All Vehicles
The DUMOS 15 cu ft roof bag offers an excellent balance of waterproofing and security with reinforced straps, a combination lock, and tearproof PVC material, making it a strong contender for outdoor enthusiasts. Compared with the larger Mockins, it sacrifices some capacity for increased security and ease of setup, particularly useful for quick trips or shorter journeys. Its universal fit and included accessories make installation straightforward on most vehicles, but the need for additional straps on some cars can be a minor hassle. While its capacity is more modest, it’s perfect for users who prioritize weather protection and theft deterrence without sacrificing ease of use.
Pros:- Waterproof, tearproof construction protects cargo in all weather
- Enhanced security features like reinforced straps and a lock
- Universal fit and easy to install on most vehicles
Cons:- May require additional straps for certain vehicle types
- Setup and folding can be challenging for some users
Best for: Outdoor adventurers or families seeking a secure, waterproof roof bag for short to medium trips.
Not ideal for: Those needing maximum cargo space or planning very long trips with bulky gear, due to its 15 cu ft limit.
- Capacity:15 cubic feet
- Material:Heavy-duty PVC
- Waterproof:Yes
- Includes:Anti-slip mat, lock, straps, hooks
Our verdict“Ideal for users prioritizing weatherproof security and quick setup over maximum storage capacity.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ 21 cu ft roof bag offers a versatile size suitable for most road trips, camping, and vacations. Unlike the DUMOS, which emphasizes security, this bag focuses on durability and ease of installation, with reinforced straps and hooks combined with a full travel kit. Its 840D PVC material is highly waterproof, making it a reliable choice for wet conditions. However, it can be bulky when stored and requires proper securing to prevent movement at high speeds. Compared to more minimalist options, this bag provides a complete package for secure transport, though its size may be less convenient for small vehicles or quick trips.
Pros:- Highly waterproof and durable material
- Large capacity fits multiple suitcases and gear
- Includes travel kit for quick, secure setup
Cons:- Bulky to store when not in use
- Requires proper securing at high speeds
Best for: Travelers seeking a reliable, waterproof cargo bag with a complete setup for road trips and outdoor adventures.
Not ideal for: Drivers with small vehicles or those needing minimal storage, due to its larger size and bulkiness.
- Capacity:21 Cubic Feet
- Material:840D PVC
- Dimensions:52 x 40 x 18 inches
- Warranty:12 Months
Our verdict“Best for those wanting a durable, waterproof roof bag with a full travel kit and ample capacity for extended trips.”
FIVKLEMNZ Car Rooftop Cargo Carrier Waterproof Roof Bag with Accessories
This FIVKLEMNZ 15 cu ft roof bag combines durability with straightforward installation, thanks to welded seams and reinforced straps. It’s comparable to the DUMOS 15 cu ft but emphasizes welded seams for superior waterproofing and a rugged build. Its universal fit makes it suitable for all vehicle types, and the included accessories support quick setup. However, some users have found securing it tightly enough at high speeds challenging, and its size may be too bulky for small vehicles. This option is well-suited for users who need reliable weather resistance and don’t mind a slightly larger, more robust bag.
Pros:- Welded seams for superior waterproofing
- Heavy-duty PVC with reinforced straps
- Universal fit with included accessories
Cons:- May be difficult to secure tightly at high speeds
- Size could be impractical for small vehicles
Best for: Drivers needing a highly waterproof, heavy-duty roof bag for unpredictable weather conditions.
Not ideal for: Small cars with limited roof space or those seeking a lightweight, minimalist option for short trips.
- Material:840D PVC
- Capacity:15 cubic feet
- Dimensions:46 x 34 x 17 inches
- Includes:Locks, straps, hooks
Our verdict“Designed for users requiring robust waterproofing and heavy-duty durability with easy universal installation.”
Asinking Car Rooftop Cargo Carrier Bag, 20 Cubic Feet Waterproof Vehicle Roof Bag for All Vehicles with/Without Rack, Includes Non-Slip Mat, Lock, Door Hooks, Storage Bag
The Asinking 20 cu ft roof bag combines a sizable capacity with an IPX66 waterproof rating, making it an attractive choice for families or long-distance travelers. Its 900D double-coated PVC laminated tarpaulin is more durable than some competitors, providing enhanced protection against rain, dirt, and road spray. Compared to the Mockins 40 cu ft, it offers less space but excels in waterproofing and ease of installation. Its aerodynamic shape helps reduce wind noise and fuel consumption, a plus on longer drives. While installation can be complex for some users, the included lock, straps, and non-slip mat contribute to a secure setup. This product is ideal for those prioritizing waterproofing and durability in a large-capacity roof bag.
Pros:- High waterproof rating with durable 900D PVC material
- Large 20 cu ft capacity suitable for family gear
- Aerodynamic design reduces noise and fuel use
Cons:- Installation can be complicated for some users
- Heavy straps may be cumbersome to handle during setup
Best for: Families or travelers seeking a waterproof, durable bag with a large capacity for extended road trips.
Not ideal for: Users with small vehicles or those who want a lightweight, simple solution for short urban trips.
- Capacity:20 cubic feet
- Waterproof Rating:IPX66
- Material:900D double-coated PVC
- Dimensions:40 L x 52 W inches
- Warranty:2 years
Our verdict“Best for users needing a large, waterproof roof bag that offers durability and reduced noise on long journeys.”
MIDABAO 20 Cubic Waterproof Car Roof Top Carrier – Cargo Roof Bag with Anti-Slip Mat and Racks Option
This option stands out for its affordability and versatility compared to pricier hard-shell carriers. With 20 cubic feet of capacity, it provides ample space for road trips or outdoor gear, yet its soft PVC material means it’s less durable and more susceptible to water leakage if not properly sealed. Unlike the Sailnovo model, which emphasizes aerodynamics, MIDABAO’s malleable design allows for easier storage when not in use, but it may require extra racks for optimal security on some vehicles. While easy to mount with straps, the soft shell offers less protection against impacts and rough weather conditions. Overall, this carrier is best suited for budget-conscious travelers who prioritize flexibility and storage size over rugged durability.
Pros:- Large 20 cubic feet capacity for substantial cargo
- Waterproof PVC protects contents from rain and splashes
- Malleable design allows simple storage when not in use
- Easy to install with multiple secure straps
Cons:- Less durable than hard-shell options, risking damage in rough conditions
- Water leakage possible if not properly sealed or mounted
Best for: Budget-conscious users needing flexible, large-capacity cargo for infrequent trips
Not ideal for: Heavy-duty travelers or those facing extreme weather, who require more durable, impact-resistant carriers
- Capacity:20 Cubic Feet
- Dimensions:51.1” x 39” x 17”
- Material:PVC
- Includes:Anti-slip mat, mounting straps
- Fits:All cars with or without roof rack
Our verdict“This carrier is ideal for budget-minded users who need flexible, large-capacity storage for mild weather and occasional use.”
Sailnovo Aerodynamic Rooftop Cargo Carrier Bag, 20 Cubic Feet Waterproof
Compared to the bulkier MIDABAO, Sailnovo’s 20 cu ft carrier emphasizes reduced wind drag thanks to its aerodynamic shape, making it a smarter choice for drivers concerned about fuel efficiency. Its tear-resistant fabric and PVC coating promise durability, but it’s not fully waterproof—extreme weather might still challenge its seams. Installation is straightforward with the provided straps and accessories, though some users report that it takes longer to set up correctly compared to simpler models. This carrier makes the most sense for families or road trippers who value a balance between large capacity and improved aerodynamics, but it’s less suited for harsh climates or frequent, rugged use.
Pros:- Large 20 cu ft capacity suitable for family gear
- Aerodynamic design reduces wind noise and improves fuel economy
- Waterproof and tear-resistant fabric for durability
- Includes straps, locks, and accessories for secure mounting
Cons:- Not 100% waterproof—caution needed in heavy rain
- Installation can be tricky on vehicles without roof racks
- Potential for longer setup times
Best for: Family travelers seeking large capacity with better fuel economy on highway drives
Not ideal for: Off-road adventurers or users in extreme weather needing ultra-durable or fully waterproof options
- Capacity:20 Cubic Feet
- Dimensions:51″ (L) x 39″ (W) x 17″ (H)
- Material:Military-grade fabric with PVC coating
- Includes:Anti-slip mat, luggage lock, straps, door hooks
- Compatible Vehicles:Most vehicles with or without roof racks
Our verdict“This carrier is perfect for families prioritizing large capacity and improved highway fuel efficiency, with some weather limitations.”
Car Roof Bag Rooftop Cargo Carrier Waterproof 21 Cubic Feet
This carrier distinguishes itself with a generous 21 cubic feet of space and security features like reinforced straps and a combination lock, making it ideal for travelers who need peace of mind. Its 800D PVC tarpaulin and grid material promise durability, but the zipper could be vulnerable under extreme conditions, and installation may demand effort to ensure stability. Unlike models like the Asinking, which emphasizes heavy-duty construction, this option balances capacity with some ease of use. It’s well-suited for long trips with valuable gear but may feel bulky when stored away.
Pros:- Largest capacity at 21 cu ft for extensive gear
- Waterproof and tearproof materials ensure durability
- Includes reinforced straps and combination lock for security
- Compatible with vehicles with or without roof racks
Cons:- Zippers may be vulnerable in extreme weather
- Bulky when stored, less portable
- Installation can be challenging for some vehicles
Best for: Travelers needing large, secure cargo space for valuables or long trips
Not ideal for: Casual users or those with limited storage for bulky, heavy-duty cargo
- Capacity:21 Cubic Feet
- Dimensions:47″ (L) x 35″ (W) x 22″ (H)
- Material:800D PVC tarpaulin, Grid material
- Includes:Anti-slip mat, 10 reinforced straps, 6 door hooks, lock
Our verdict“This carrier is best for users needing maximum security and capacity for long, gear-heavy trips.”
Asinking Car Rooftop Cargo Carrier Bag – 100% Waterproof, Heavy Duty, 21 Cubic Feet
Compared with softer fabric options, Asinking’s 21 cu ft carrier stands out for its heavy-duty 900D PVC construction, making it suitable for harsh weather and rugged use. Its reinforced seams and secure straps maximize safety during long trips, but the bulkiness can make storage and installation slightly more cumbersome. While other models like Sailnovo focus on aerodynamics, Asinking prioritizes durability and security, which may add weight to the vehicle. It’s a strong choice for those facing frequent severe weather or off-road conditions, but less ideal for casual or infrequent travelers who prefer lightweight options.
Pros:- 100% waterproof and rip-proof for harsh conditions
- Heavy-duty 900D PVC material for durability
- Secure straps, buckles, and a combination lock for safety
- Long-lasting construction suitable for rugged environments
Cons:- Bulky and heavier, complicating storage and handling
- Installation may require adjustments for different roof types
- More expensive than softer fabric alternatives
Best for: Adventurers and frequent travelers needing rugged, impact-resistant cargo protection
Not ideal for: Casual users or those seeking lightweight, easy-to-store options for occasional trips
- Capacity:21 Cubic Feet
- Dimensions:52″L x 40″W x 18″H
- Material:900D abrasion-resistant PVC
- Includes:Non-slip mat, combination lock, door hooks, storage bag
- Weight:Approx. (not specified)
Our verdict“This carrier is ideal for users needing maximum durability and weather resistance in rugged environments.”
MARCHWAY Waterproof Car Roof Luggage Bag, Weatherproof Soft Shell Rooftop Cargo Carrier, 21 Cubic Feet, Black
Compared with the more rugged Asinking, MARCHWAY offers a soft-shell carrier that emphasizes ease of use and storage flexibility. Its 21 cu ft capacity makes it suitable for most vehicle types, including off-roaders, while its tear-resistant 900D PVC material ensures good weather protection. The permanently attached straps and quick installation make setup faster, but the overall bulkiness can still pose challenges for storage when not in use. For travelers prioritizing simplicity and convenience over extreme durability, MARCHWAY provides a solid balance, though it may not withstand severe impacts or extreme weather as well.
Pros:- Large 21 cubic feet capacity for versatile cargo
- Durable, waterproof, tear-resistant materials
- Simple, quick installation with permanent straps
- Foldable for compact storage
Cons:- May not fit all vehicle types perfectly
- Straps and hooks require proper adjustment for security
- Can be noisy at high speeds
Best for: Road trippers and outdoor enthusiasts seeking an easy-to-install, large-capacity carrier
Not ideal for: Heavy-duty or off-road users demanding maximum impact resistance and weatherproofing
- Capacity:21 Cubic Feet
- Material:900D waterproof PVC
- Dimensions:Fits most vehicles with or without racks
- Includes:Anti-slip mat, door hooks, combination lock
- Weight:11.9 lbs
Our verdict“This carrier suits casual outdoor travelers who value convenience and capacity over rugged impact resistance.”
WORKPRO Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Car Roof Bag
The WORKPRO rooftop cargo carrier stands out for its generous 21 cubic feet capacity combined with durable 840D PVC waterproof material. Compared to the FIVKLEMNZ model, it offers more straps and safety features like reflective strips, making installation more secure and visible. However, as a soft shell, it cannot match the impact protection of a hard-shell carrier, meaning it’s better suited for protecting gear from weather rather than impacts. The multiple straps and included hooks make setup straightforward on various vehicles, but improper installation can cause leaks or tearing. This pick is ideal for travelers needing high capacity and safety features, especially on longer trips where weather resistance matters. It’s less suited for those seeking a rigid carrier for rugged impacts or very frequent, rough usage.Pros:- Large 21 cubic feet capacity for substantial gear loads
- Waterproof and durable 840D PVC material
- Easy to install with multiple reinforced straps and safety features
Cons:- Lacks impact protection due to soft-shell design
- Potential for leaks if straps are improperly installed or if damaged
Best for: Families or outdoor enthusiasts needing large, waterproof storage with safety features for extended trips.
Not ideal for: Users wanting impact protection or frequent rough handling, since the soft shell offers limited impact resistance.
- Capacity:21 cubic feet
- Dimensions:52″ x 40″ x 17″
- Material:840D PVC
- Number of straps:10 reinforced adjustable straps
- Includes:6 door hooks, 2 reinforced straps, 1 storage bag, 1 user manual
Our verdict“This carrier suits those prioritizing capacity and weather resistance over impact protection.”
Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cuft, Fits Cars with/Without Rack
The Sailnovo cargo bag offers a slightly smaller 20 cubic feet capacity but excels in versatility, fitting on most vehicles with or without racks. Its tear-resistant 1000D Oxford cloth makes it highly durable, especially compared to the softer PVC options like the Asinking bag, which may be more prone to tearing under stress. This model is easy to install with included straps and can be folded when not in use, appealing to those with limited storage space or infrequent use. However, it may overhang on smaller cars or vehicles with sunroofs, and proper filling is necessary to prevent water pooling. It makes the most sense for occasional travelers needing a flexible, durable option that doesn’t require permanent roof rack installation.Pros:- Tear-resistant 1000D Oxford fabric for durability
- Easy to install and foldable for compact storage
- Fits on vehicles with or without roof racks
Cons:- May overhang on small or low-clearance vehicles
- Requires proper filling to avoid water pooling
Best for: Occasional travelers or those with limited storage space needing a versatile, durable roof bag.
Not ideal for: Frequent users or those with very small vehicles where overhang might cause issues or instability.
- 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 bag provides flexible, durable storage for occasional use on a variety of vehicle sizes.”
Asinking Car Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof, Fits All Cars with/without Rack
The Asinking cargo bag offers a generous 21 cubic feet of waterproof storage with reinforced seams and lockable security features. Compared to the Sailnovo, it emphasizes added security with locks and reinforced seams, making it suitable for travelers concerned about theft or tampering. Its universal fit helps it adapt to most vehicles, but some users report difficulty with straps, especially on complex roof shapes. The soft shell design offers flexibility, though it provides less impact protection than hard-shell options, making it better suited for weather protection and secure storage rather than rugged impact resistance. It’s a solid choice for road trips where security and waterproofing are priorities.Pros:- Waterproof and tearproof construction
- Includes locks and reinforced seams for security
- Universal fit compatible with all vehicles
Cons:- Can be difficult to secure straps properly
- Less impact resistant than rigid carriers
Best for: Road trippers needing secure, waterproof storage with a universal fit and added security features.
Not ideal for: Those seeking impact protection or driving in extremely rough conditions, as its soft shell offers limited impact resistance.
- 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
- Warranty:2 years
Our verdict“This carrier is ideal for travelers prioritizing security and waterproofing over impact protection.”
21 CuFt Waterproof Rooftop Cargo Bag with Straps, Hooks, and Anti-Slip Mat
This 21 cubic feet cargo bag features durable 840D PVC tarpaulin, designed for large gear loads with easy setup and security locks. Compared to Asinking, it emphasizes larger capacity and includes more straps, which can make securing it easier, especially on larger vehicles like SUVs. Its soft shell construction offers flexibility but less impact protection than a rigid carrier, making it suitable for weatherproofing and secure luggage transport. The bulkiness when stored can be a drawback for those with limited garage space, and it requires a roof rack for optimal fit. It’s best for those needing a high-capacity, secure, waterproof option for frequent trips.Pros:- Large 21 cubic feet capacity for multiple items
- Waterproof and durable 840D PVC material
- Includes multiple straps and security locks
Cons:- Bulky when not in use, requiring storage space

Not ideal for: Owners of small cars or those looking for a compact, minimalistic solution, since it can be bulky when stored.
- Capacity:21 cubic feet
- Dimensions:52″ x 40″ x 18″
- Material:840D PVC tarpaulin
- Includes:10 straps, 6 hooks, anti-slip mat, storage bag, lock
- Warranty:24 months
Our verdict“This bag excels for high-capacity, secure, weatherproof storage on larger vehicles but can be cumbersome to store when empty.”

How We Picked
Products were evaluated based on capacity, waterproof performance, ease of installation, build quality, and value for money. We prioritized models with strong customer reviews, reliable waterproofing, and compatibility with a wide range of vehicles. The ranking reflects a balance between size, durability, and price, aiming to recommend options suitable for both casual users and more frequent travelers. Items with notable accessories or unique features were given additional consideration to provide a comprehensive overview of what buyers need to make an informed choice.Factors to Consider When Choosing Roofcargo Carriers Soft Shell
Choosing the right soft-shell roof cargo carrier involves more than just capacity. You should consider how well it resists water, how easy it is to install, and whether it fits your vehicle. Budget, durability, and ease of maintenance are also key. Being aware of common pitfalls, like overloading or poor attachment, helps ensure safety and longevity. This guide covers essential factors to help you select a carrier that matches your specific travel needs and vehicle setup.Capacity and Size
Capacity determines how much gear you can carry, but larger bags tend to be bulkier and more difficult to mount securely. Consider your typical load—if you frequently travel with a family or bulky gear, a larger capacity like 40 CuFt might be necessary. However, for occasional trips or urban vehicles, a smaller, more manageable size could be preferable. Pay attention to dimensions and ensure your vehicle has enough clearance, especially if you have a low-profile roof.
Waterproofing and Material Durability
Soft-shell carriers are valued mainly for their waterproof features. Look for models with high-quality, UV-resistant, and tear-proof materials like heavy-duty nylon or polyester with waterproof coatings or sealed seams. Cheaper options may claim waterproofing but often fail under heavy rain or prolonged exposure. Investing in a well-made waterproof bag protects your gear and reduces the risk of damage during stormy or wet conditions.
Ease of Installation and Compatibility
Ease of attachment is critical—look for models with adjustable straps, reinforced attachment points, and clear instructions. Some bags are designed to fit specific roof rack types, while others are more universal. Compatibility with your vehicle’s roof height and rack system can prevent installation headaches. Misaligned or insecure mounting can lead to safety issues or gear loss during transit, so prioritize models with flexible and straightforward attachment methods.
Security Features
Security options like lockable zippers or straps help prevent theft, especially if you plan to leave your vehicle unattended. Some models include integrated locks or additional security accessories. While locks add peace of mind, they can also complicate access. Balance the need for security with convenience based on your travel environment and how often you’ll need quick access to your gear.
Price and Value
Pricing varies widely, with budget models offering basic waterproofing and capacity, while premium options come with extra features and improved durability. Consider how often you’ll use the carrier—if it’s a one-time purchase, investing in a higher-quality model makes sense. Conversely, for occasional use, a more affordable option might suffice. Remember, cheaper carriers may require replacement sooner, so evaluate the long-term value against the initial cost.
Frequently Asked Questions
Can a soft-shell roof cargo carrier fit on any vehicle?
Most soft-shell roof carriers are designed to be compatible with a wide range of vehicles, including cars, SUVs, and crossovers. However, it’s essential to check the product specifications for maximum width and whether your roof supports the attachment system. Vehicles without roof racks or with non-standard roof rails might require additional mounting accessories. Confirming compatibility in advance helps avoid installation issues and ensures your gear is secure during transit.
How waterproof are these carriers in heavy rain?
High-quality soft-shell carriers generally provide reliable waterproof protection, especially those with sealed seams and waterproof fabrics like reinforced nylon or polyester. Cheaper models might offer some water resistance but can leak during heavy or prolonged rain. Investing in a carrier with proven waterproof features reduces the risk of gear damage, particularly on long trips or in unpredictable weather conditions.
Are soft-shell roof bags easy to remove and store?
Yes, most soft-shell carriers are lightweight and designed for quick installation and removal. They typically fold flat, making storage convenient when not in use. However, some larger models may be bulkier to handle, especially when filled. If you frequently switch between carrying gear and using your roof for other purposes, choose a bag with straightforward straps and minimal bulk to simplify handling.
What’s the best way to secure my gear in a soft-shell roof carrier?
Using the provided straps, tighten the bag securely to prevent shifting during travel. Many models include additional features like anti-slip mats or locking zippers that enhance security. For added safety, consider using extra straps or locks if you leave your vehicle unattended. Properly securing your gear not only protects it but also maintains vehicle stability and safety on the road.
How durable are these soft-shell carriers over time?
The durability of soft-shell carriers depends on the quality of materials and construction. Premium models with reinforced seams, UV-resistant fabrics, and heavy-duty zippers tend to last longer, even with frequent use. Cheaper options might degrade faster, especially if exposed to harsh weather or rough handling. Regular cleaning and proper storage when not in use can extend the life of your carrier significantly.
