More Details on Our Top Picks
Asinking Car Rooftop Cargo Carrier Bag – 100% Waterproof, Heavy Duty, 21 Cubic Feet
The Asinking cargo bag stands out for its large 21 cubic feet capacity combined with a highly waterproof and durable design, making it a strong choice for families needing extensive storage. Unlike the Mockins bag, which offers slightly more volume but with a 10-year warranty, the Asinking emphasizes reinforced seams and abrasion-resistant PVC to withstand tough weather conditions. Its universal fit and included security features—like straps and a lock—add to its appeal, though it can be bulky when stored and might need some extra effort during installation on various roof types. This model is ideal for those prioritizing capacity and rugged durability, even if handling the straps requires some strength.Pros:- Exceptional waterproof and abrasion-resistant construction
- Generous 21 cu ft capacity for multiple large items
- Universal fit with simple installation on most vehicles
- Includes security features like straps, locks, and hooks
Cons:- Bulky to store when not in use

Our verdict“This cargo bag is best suited for users needing maximum capacity and durability, accepting some bulkiness for tough weather protection.”
Mockins 25 CuFt Waterproof Rooftop Cargo Bag for Top of Car 60″x43″x17″
The Mockins cargo bag offers a massive 25 cubic feet of waterproof storage, surpassing most competitors like the Sailnovo 20 cu ft model in volume. Its abrasion-resistant 840D fabric and waterproof zippers provide reliable weather protection, and the included straps, hooks, and a 10-year warranty make it a comprehensive package. Compared with the FIVKLEMNZ model, which shares a similar capacity but lacks a warranty, Mockins provides peace of mind for long-term outdoor use. However, its size and weight can make installation more cumbersome, and it may not fit all roof types perfectly. This pick is best for those needing extensive cargo space combined with a robust accessory set, but it demands careful handling during setup.Pros:- Largest capacity at 25 cu ft for maximum storage
- Weather-resistant with waterproof zippers and durable fabric
- Includes comprehensive straps, hooks, and warranty for peace of mind
- Foldable for easy storage when not in use
Cons:- Heavy and bulky, making installation more effortful

Rooftop Cargo Carrier 15 Cu Ft Waterproof Soft Shell Roof Bag
Offering 15 cubic feet of storage, the Rooftop Cargo Carrier is well-suited for travelers who prefer a lighter, more flexible option. Its military-grade 600D polyester makes it resilient against weather, but compared with the larger, more rugged options like the Asinking bag, it provides less volume and durability under extreme conditions. The simple installation process and compatibility with most roof racks make it accessible for many users, but it’s less ideal for those carrying bulky or sharp-edged gear that might damage the fabric. This model makes the most sense for users who prioritize ease of use over maximum capacity, especially on shorter trips or with smaller vehicles.Pros:- Weather-resistant and durable construction
- Easy to install with universal compatibility
- Includes protective accessories like anti-slip mat
- Lightweight and flexible for quick setup
Cons:- Limited capacity compared to larger bags
- Requires roof rack for installation
- Not suitable for glass or panoramic roofs
Best for: Casual campers or small-family travelers seeking a weatherproof roof bag with straightforward setup.
Not ideal for: Heavy-duty users needing maximum capacity or those carrying sharp or heavy equipment regularly.
- Capacity:15 cubic feet
- Dimensions:44” x 34” x 17”
- Material:600D polyester
- Includes:door-hook straps, anti-slip mat, storage bag
Our verdict“This soft shell roof bag is best for moderate storage needs and easy handling, though it sacrifices some capacity and ruggedness.”
FIVKLEMNZ 21 Cubic Rooftop Cargo Carrier Waterproof Soft Car Roof Bag
The FIVKLEMNZ model offers 21 cubic feet of waterproof storage with reinforced straps and hooks, making it comparable to the Asinking bag but with a softer, more flexible fabric. Its heavy-duty waterproof PVC ensures protection against rain, while the multiple straps and hooks provide reliable attachment. Compared to the Sailnovo 20 cu ft model, it emphasizes more secure attachment points, though it may be less rigid and more susceptible to wear over time. This bag is suited for those who need a rugged, waterproof soft shell option that’s easy to fold and store, but handling ten straps for installation can be time-consuming for beginners.Pros:- Very waterproof with reinforced PVC fabric
- Heavy-duty straps and hooks for secure attachment
- Flexible, foldable, and easy to store
- Provides reliable weather protection for gear
Cons:- Installation involves managing multiple straps, which can be cumbersome
- Less rigid than hard-shell carriers, potentially less protective against sharp objects
Best for: Road trip enthusiasts who prefer a flexible, waterproof soft shell option with heavy-duty features.
Not ideal for: Users seeking a rigid, high-capacity cargo carrier or those who dislike complicated strap setups.
- Capacity:21 cubic feet
- Material:840D PVC
- Dimensions:52 x 40 x 18 inches
- Includes:10 straps, door hooks, anti-slip mat
Our verdict“This soft shell cargo bag is ideal for rugged waterproof protection with flexible storage, accepting some installation complexity.”
Sailnovo Rooftop Cargo Carrier Roof Bag, 20 Cu Ft, Fits Cars with/Without Rack
The Sailnovo 20 cu ft rooftop bag offers a practical balance of capacity and flexibility, suitable for carrying tents, sleeping bags, and luggage. Its 1000D Oxford cloth makes it highly tear-resistant, and the foldable design allows easy storage when not in use. Compared with the FIVKLEMNZ soft shell, Sailnovo emphasizes portability and ease of handling, though it offers slightly less waterproofing. It’s not recommended for vehicles with sunroofs or for carrying very sharp or heavy gear that could damage the fabric. This choice makes the most sense for travelers who need a reliable, foldable waterproof bag that can adapt to different vehicle types and storage needs.Pros:- Water-resistant, tear-resistant 1000D Oxford fabric
- Foldable for compact storage
- Universal fit for most roof types
- Suitable for carrying camping or travel gear
Cons:- Less waterproof than PVC-based bags under heavy rain
- Requires proper filling to prevent water pooling
- Overhang possible on very small or compact cars
Best for: Casual campers or road-trippers seeking a versatile, foldable waterproof roof bag for moderate loads.
Not ideal for: Heavy-duty users with high-volume needs or those transporting sharp or heavy gear regularly.
- Capacity:20 cubic feet
- Material:1000D Oxford cloth
- Dimensions:51″ x 39″ x 17″
- Includes:6 tie-down straps, 6 door hooks, storage bag, manual
Our verdict“This versatile, foldable waterproof bag works well for moderate loads and casual use, with some limitations on waterproofing under extreme weather.”
WORKPRO Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Car Roof Bag
The WORKPRO rooftop cargo carrier stands out for offering a generous 21 cubic feet of waterproof storage, making it ideal for large families or extended trips. Its reinforced straps and reflective strips enhance safety and stability, while the durable 840D PVC material provides reliable weather resistance. Compared with the Sailnovo 21 cu ft model, WORKPRO’s multiple straps and safety features give it an edge in secure attachment, but it’s less rigid than hard-shell options, which can be a drawback in very extreme weather. Still, this flexible soft bag offers practical versatility for most travel needs, especially when you value capacity and safety features.
Pros:- Large 21 cubic feet capacity for multiple luggage pieces
- Weather-resistant, durable PVC material
- Easy installation with multiple reinforced straps
- Includes safety features like reflective strips

- Capacity:21 cubic feet
- Dimensions:52″ x 40″ x 17″
- Material:840D PVC
- Number of straps:10 reinforced adjustable straps
- Includes:6 safety hooks, 2 reinforced straps, 1 storage bag, 1 user manual
Our verdict“This bag is best suited for travelers prioritizing capacity and safety in a flexible, weatherproof design.”
Car Rooftop Cargo Carrier Bag, 15 Cubic Feet Waterproof Heavy Duty 840D Car Roof Bag for All Vehicles with/without Racks
This heavy-duty rooftop cargo bag offers 15 cubic feet of waterproof space, making it a solid choice for those who need reliable protection without the bulk of larger models like Sailnovo or RoofPax. Its abrasion-resistant 840D PVC fabric ensures durability, especially in rough conditions, but the smaller capacity means it’s less suitable for extended family trips. Unlike the Sailnovo soft bag, its stiff material might be less forgiving in tight storage spaces, and the lack of specific dimensions could complicate sizing. Nonetheless, it delivers a well-constructed, weatherproof option for everyday travel where durability is a priority.
Pros:- Heavy-duty, abrasion-resistant 840D PVC fabric
- Weatherproof with reinforced seams and waterproof zippers
- Easy to install with adjustable straps and accessories
- Reliable for everyday or short-term trips
Cons:- No specific dimensions provided, which may complicate fit
- Less flexible due to stiff fabric, potentially harder to store
Best for: Budget-conscious buyers needing a tough, waterproof bag for moderate luggage loads
Not ideal for: Large groups or those needing maximum cargo volume, as it may fall short on space
- Material:840D PVC fabric
- Capacity:15 cubic feet
- Includes:Storage bag, anti-slip mat, door hooks, extra straps, luggage lock
- Warranty:2 years
Our verdict“This bag offers durable, waterproof protection in a compact package for budget-minded travelers.”
Sailnovo Car Rooftop Cargo Carrier 21 Cubic Feet Waterproof Soft Roof Bag
The Sailnovo 21 cu ft soft roof bag excels with military-grade waterproof material, making it ideal for serious outdoor enthusiasts facing unpredictable weather. Its 21 cubic feet capacity rivals the WORKPRO bag, but its soft design allows it to conform better to different vehicle shapes and easier storage when not in use. Compared to the rigid RoofPax, Sailnovo’s material is more flexible, but this also means less impact protection. Installation is straightforward with included straps and accessories, although its compatibility is limited to vehicles with roof racks or side rails, unlike some universal options like RoofPax. For rugged, weatherproof travel, this bag delivers excellent waterproofing and versatility.
Pros:- Military-grade waterproof 1000D PVC material
- Large 21 cubic feet capacity

- Includes comprehensive accessories for secure installation

- Capacity:21 cubic feet
- Material:1000D PVC tarpaulin
- Compatibility:Most roofs with crossbars, side rails, or bare tops
- Includes:Roof cargo carrier, storage bag, combination lock, anti-slip mat, safety hooks
Our verdict“This soft roof bag offers rugged waterproof protection with adaptability for outdoor adventurers, but requires compatible vehicle features.”
RoofPax 23 cu ft Waterproof Rooftop Cargo Carrier Bag with Double Zippers and Tie-Down Straps
The RoofPax 23 cu ft cargo bag leads in safety and weatherproofing with double waterproof zippers and patented tie-down straps, making it an excellent choice for long-distance or unpredictable weather conditions. Its 23 cubic feet capacity surpasses most soft bags, providing ample room for bulky luggage. Compared with the slightly smaller Sailnovo, RoofPax emphasizes security with specialized straps and waterproof features, but the heavier straps and installation process might be cumbersome for some users. Suitable for vehicles with or without roof racks, it offers peace of mind during challenging weather, although its bulkier design may be less convenient for daily storage.
Pros:- Maximizes safety with patented door hook straps
- Heavy-duty, double waterproof zippers
- Compatible with vehicles with or without roof racks

Its installation is straightforward with adjustable straps and an anti-slip mat, yet its bulky nature might make storage or handling more challenging when not in use.

How We Picked
These products were evaluated based on waterproof performance, material durability, capacity, ease of installation, and price. We prioritized models with proven waterproofing features, such as sealed seams and high-quality fabrics, to ensure gear stays dry in heavy rain. The ability to securely attach the bag to various vehicle types was also key, along with user-friendly features like multiple tie-down points. Our ranking balances these factors with value, favoring options that offer reliable waterproof protection without unnecessary complexity or cost. This approach ensures buyers can find a model suited to different budgets and needs, from casual trips to more demanding weather conditions.Factors to Consider When Choosing Rooftop Cargo Bag Waterproof
Choosing the right waterproof rooftop cargo bag involves more than just capacity. Consider how the bag’s material and construction will perform in heavy rain or snow, and whether it’s easy to install securely on your vehicle. Size and capacity should match your typical gear needs without overburdening your vehicle or sacrificing ease of handling. Price and additional features like tie-downs, zippers, and ease of access also play important roles. Being aware of these factors helps avoid common mistakes, such as buying a bag that’s too small, too heavy, or not sufficiently waterproof for your climate.Material and Waterproofing
Look for bags made from high-quality, waterproof fabrics such as 840D nylon or PVC-coated materials. Fully sealed seams and waterproof zippers are essential to prevent leaks. Cheaper fabrics or partial waterproofing may lead to gear getting wet during heavy rain or snow, which defeats the purpose of a waterproof bag. Investing in a higher-grade material can be worthwhile if you frequently travel in adverse weather or carry sensitive gear.
Capacity and Size
Assess your typical cargo needs—whether it’s camping gear, luggage, or sports equipment—and choose a bag that offers enough space without overloading your vehicle. Larger bags, like the Mockins 25 CuFt, provide more room but can be heavier and harder to install securely. Conversely, smaller bags are easier to handle but may limit what you can carry. Consider your vehicle’s roof dimensions and whether the bag’s shape and size fit well without obstructing visibility or affecting aerodynamics.
Ease of Installation and Security
A bag that’s simple to install saves time and reduces frustration, especially for those who switch vehicles or travel frequently. Look for models with multiple tie-down points, adjustable straps, and clear installation instructions. Security features like double zippers, lockable closures, and reinforced straps help prevent theft and ensure the bag remains secure during high-speed travel or windy conditions. Remember, a poorly secured bag risks shifting or detaching, which can be dangerous.
Additional Features and Accessories
Extras such as reflective strips, waterproof zippers, and easy-access openings can enhance usability and safety. Some models include tie-down straps or compression features to keep contents stable. Consider whether you need features like foldability for storage or compatibility with racks and crossbars. While these add convenience, they may also increase the cost—so weigh their importance against your budget and travel frequency.
Price and Value
While premium models often provide superior waterproofing, durability, and features, they come at a higher cost. Budget options can be effective for occasional use, but may lack long-term resilience or advanced waterproofing. Balance your expected frequency of use, climate, and gear needs with your budget. Sometimes, paying slightly more upfront results in a bag that lasts longer and performs better in challenging weather conditions, offering better overall value.
Frequently Asked Questions
Will a waterproof rooftop cargo bag keep my gear dry in a heavy snowstorm?
Yes, a well-made waterproof rooftop cargo bag with sealed seams and waterproof zippers can protect your gear during snowstorms. However, snow can melt and refreeze, potentially causing leaks if seams aren’t fully sealed or if the bag isn’t properly secured. It’s also important to clear snow from the bag regularly during long trips to prevent excessive weight and moisture buildup. Choosing a bag with reinforced waterproof fabric and double-sealed seams offers the best protection against snow and rain alike.
How do I prevent water from leaking through the zippers?
High-quality waterproof zippers are designed to prevent leaks, but additional measures like using zipper covers or sealing tape can enhance protection. Some bags feature double zippers or storm flaps that shield the main zipper from direct exposure. Proper installation and ensuring the zippers are fully closed and aligned also help. Regularly inspecting and maintaining zippers can prevent issues over time, especially after exposure to harsh weather conditions.
Can I use a waterproof rooftop bag without a rack on my vehicle?
Absolutely, many soft-shell rooftop cargo bags are designed to be versatile and can attach directly to your vehicle’s roof or to a rack if you have one. For vehicles without racks, look for bags with adjustable straps that can secure around the roof or door frames. Be cautious to avoid over-tightening, which can damage paint or cause the bag to shift. Proper securing is essential to prevent movement during travel, especially at highway speeds.
What’s the best way to store my rooftop cargo bag when not in use?
Most waterproof cargo bags are foldable and can be compressed into a small size for storage. To prolong their lifespan, store them in a cool, dry place away from direct sunlight, which can degrade fabrics over time. Before storing, ensure the bag is completely dry to prevent mold or mildew. Keeping it in a breathable storage bag or container further protects it while not in use, ready for your next trip.
How much capacity do I need for a family camping trip?
For a family camping trip, a capacity of around 20-25 cubic feet generally suffices to carry tents, sleeping bags, and other gear. Larger bags like the Mockins 25 CuFt provide ample space but may be heavier and more cumbersome. Consider the total volume of your gear and choose a bag that offers a bit of extra room to avoid overstuffing. Also, ensure your vehicle can handle the weight without affecting handling or safety.
Conclusion
For casual travelers and those new to rooftop cargo bags, a model like the Rooftop Cargo Carrier 15 Cu Ft Waterproof Soft Shell Roof Bag offers simplicity and ease of use. If you need maximum capacity and durability, the Mockins 25 CuFt Waterproof Rooftop Cargo Bag provides excellent value and space. For high-end, feature-rich options with enhanced security, the RoofPax 23 cu ft Waterproof Rooftop Cargo Carrier makes a compelling choice. Ultimately, your selection should match your typical travel needs, climate, and budget—whether you’re seeking affordability, rugged durability, or premium features.
