Vehicle rooftop cargo carriers add space for trips, but the right choice depends on your roof setup, load, and tolerance for installation and storage. I’d make the RoofPax XXL 28-Cubic-Foot Bag my overall pick for buyers who need generous soft-sided capacity, while the SportRack Vista XL suits those who prefer a rigid box with rear access. For a smaller, hard-shell option, the D SOLUTIONS 11-Cubic-Foot Carrier is a distinct alternative. Soft bags pack away more easily, while hard boxes and baskets offer different tradeoffs in access, support, and storage. Read on for the full comparison and help matching a carrier to your vehicle and cargo.

Key Takeaways
- Capacity is the clearest split: RoofPax’s 28-cubic-foot bag and FIVKLEMNZ’s 30-cubic-foot model serve bulky loads, while the D SOLUTIONS hard shell holds 11 cubic feet for buyers with less gear.
- Soft bags dominate the lineup: They offer flexible, stowable storage, but their fit and protection depend on proper attachment, loading, and the vehicle’s roof setup.
- The SportRack Vista XL stands apart: Its rigid construction and rear-opening access offer a different loading experience from the soft bags, with less convenient off-vehicle storage.
- The MeeFar basket-and-bag combination is the format outlier: It pairs an open basket with a waterproof bag, making it a different choice from a standalone carrier bag or enclosed box.
- Several models cluster around 15 to 21 cubic feet: In that range, buyers should compare attachment hardware, included accessories, shape, and vehicle compatibility rather than capacity claims alone.

More Details on Our Top Picks
KMFurnila 15-Cubic-Foot Waterproof Rooftop Cargo Carrier Bag
The KMFurnila pairs a manageable 15-cubic-foot capacity with a sealed 700D PVC shell, making it a practical pick when keeping luggage dry matters more than maximizing volume. Its heat-sealed construction and zipper flap provide a more weather-focused setup than the Sailnovo 20-Cubic-Foot Aerodynamic Rooftop Cargo Carrier Bag, whose listing warns that it is not fully waterproof in extreme weather. KMFurnila also includes an anti-slip mat, reinforced straps, door hooks, and a luggage lock, so buyers get several mounting and security accessories in one package.
The tradeoff is the soft shell: it cannot shield contents from impacts as well as the rigid D SOLUTIONS Hard Shell Rooftop Cargo Carrier. Its 15 cubic feet also leaves less room for bulky family loads than the RoofPax XXL 28-Cubic-Foot Bag. I’d choose it for moderate luggage loads and weather protection, not hard-sided security or maximum capacity.
Pros:- 15-cubic-foot capacity suits a moderate luggage load without the scale of the RoofPax XXL.
- 700D PVC fabric, heat-sealed construction, and a protective zipper flap are designed to resist water.
- Includes an anti-slip mat, reinforced straps, door hooks, and a luggage lock.
- Fits vehicles with or without roof racks.
Cons:- Soft sides offer less impact protection and structure than the D SOLUTIONS hard-shell box.
- Its 15-cubic-foot capacity is limited compared with the 20- and 28-cubic-foot bags in this group.
Best for: Drivers who want a weather-focused soft carrier for a moderate amount of luggage and need a setup compatible with vehicles with or without roof racks.
Not ideal for: Travelers carrying fragile items or very large family loads who need hard-shell impact protection or substantially more cargo volume.
- Capacity:15 cubic feet
- Material:700D PVC
- Water resistance:Waterproof
- Mounting:Roof mount
- Vehicle fit:Universal; compatible with vehicles with or without roof racks
- Included accessories:Anti-slip mat, reinforced straps, door hooks, storage bag, and luggage lock
- Color:Dark orange
- Warranty:1 year
Our verdict“Choose the KMFurnila if you want a rack-compatible, weather-focused soft bag for moderate loads, but skip it for fragile cargo or maximum capacity.”
RoofPax XXL 28-Cubic-Foot Waterproof Rooftop Cargo Carrier Bag
Among these soft carriers, the RoofPax XXL is the clear choice when the packing list is the main problem: its 28-cubic-foot capacity exceeds the 20-cubic-foot MIDABAO and Sailnovo bags. It is designed for vehicles with or without roof racks, which gives it a broader fit range than the crossbar-dependent D SOLUTIONS hard box. Door-hook straps, a combination lock, and a storage bag are included, while the listed zipper and buckle lifetime warranty and five-year fabric-tear warranty offer unusually specific coverage for key components.
That capacity comes with a sizable footprint—52 × 39.37 × 24 inches—so buyers should check roof space and vehicle fit before choosing it. Its polyester soft shell also provides less impact protection than D SOLUTIONS’ ABS box, and the listing does not give folded dimensions for storage between trips. I’d rank it highest for volume, not for compact storage or rigid protection.
Pros:- 28-cubic-foot capacity is the largest among the five products reviewed here.
- Fits vehicles with or without a roof rack.
- Includes four door-hook straps or clips, a combination lock, and a storage bag.
- Lists lifetime coverage for zippers and buckles and five-year coverage for fabric tears.
Cons:- Its 52 × 39.37 × 24-inch dimensions require careful roof-fit checks.
- Folded dimensions are not specified, making storage planning harder.
- The soft polyester shell offers less impact protection than the D SOLUTIONS ABS cargo box.
Best for: Families or road-trippers with large, bulky loads who need high soft-carrier capacity and a model designed to work with or without roof racks.
Not ideal for: Drivers with limited roof space, little room to store a bulky bag, or cargo that needs the impact protection of a hard-shell box.
- Model:MRP-BAG28
- Capacity:28 cubic feet
- Dimensions:52 × 39.37 × 24 inches
- Weight:6.75 kg
- Material:Polyester
- Water resistance:Waterproof
- Vehicle fit:Universal; with or without roof rack
- Included accessories:Four door-hook straps or clips, combination lock, and storage bag
- Warranty:Lifetime for zippers and buckles; 5 years for fabric tears
Our verdict“Pick the RoofPax XXL when you need the most soft-bag volume and have room for its large footprint, rather than a rigid shell or compact stored size.”
Sailnovo 20-Cubic-Foot Aerodynamic Rooftop Cargo Carrier Bag
The Sailnovo offers 20 cubic feet of storage in a listed 17-inch height, a lower profile than the RoofPax XXL’s listed 24 inches. That shape is intended to reduce wind drag and noise, making this a candidate for drivers who want to carry camping gear without choosing the tallest bag in the lineup. Its PVC-coated, tear-resistant fabric and included anti-slip mat, detachable and reinforced straps, door hooks, and luggage lock provide a substantial mounting kit. It also fits many vehicles with or without racks, crossbars, or baskets.
The key compromise is weather protection: the listing says it is not fully waterproof in extreme weather and recommends pointing the zipper-less side forward. The listed height also conflicts—17 inches in the description and 27 inches in the specifications—so fit checks are less certain than with the MIDABAO, which lists a consistent 17-inch height. I’d favor Sailnovo for its intended lower profile, but not for exposed trips where maximum weather confidence comes first.
Pros:- 20-cubic-foot capacity accommodates luggage and camping gear.
- Lower-profile 17-inch description dimension is intended to reduce wind drag and noise.
- Includes an anti-slip mat, multiple straps, door hooks, a luggage lock, and a storage bag.
- Fits many vehicles with or without roof racks, crossbars, or baskets.
Cons:- The listing says it is not fully waterproof in extreme weather.
- Height is inconsistent: 17 inches in the description and 27 inches in the specifications.
- Correct orientation matters; the listing recommends facing the zipper-less side forward.
Best for: Drivers who want a 20-cubic-foot soft carrier with a lower-profile design and a broad fit range for vehicles with or without roof hardware.
Not ideal for: Travelers expecting severe-weather exposure or buyers who need consistent, unambiguous height information before checking roof clearance.
- Capacity:20 cubic feet
- Dimensions:51 × 39 × 17 inches in description; 51 × 39 × 27 inches in specifications
- Weight:3.9 kg
- Material:Military-grade fabric with PVC coating
- Vehicle compatibility:Most vehicles with or without roof racks, crossbars, or baskets
- Water resistance:Not fully waterproof in extreme weather
- Included components:Anti-slip mat, storage bag, luggage lock, 4 detachable straps, 2 reinforced straps, and 6 door hooks
- Warranty:1 year
Our verdict“Choose Sailnovo for a potentially lower-profile 20-cubic-foot bag and broad vehicle compatibility, but not when severe-weather protection or clear dimensions are your priority.”
MIDABAO 20-Cubic-Foot Waterproof Car Roof Cargo Carrier
MIDABAO is the straightforward choice for buyers who want 20 cubic feet without the extra uncertainty found in some soft-bag listings. Its dimensions are consistently stated as 51.1 × 39 × 17 inches, unlike the Sailnovo, whose listed height differs between the description and specifications. PVC-coated material and coated zippers are described as waterproof, while the included six short straps, two long straps, and anti-slip mat give buyers several attachment pieces for vehicles with or without roof racks.
It is less specialized than Sailnovo’s aerodynamic positioning and less weather-focused in its stated construction details than the KMFurnila’s heat-sealed PVC build. It also lacks the extra lock and door hooks included with some alternatives. Like the other soft bags, MIDABAO has less structure and impact protection than the D SOLUTIONS hard box. I’d choose it for a simple, defined-size 20-cubic-foot carrier, not for rigid protection or a more complete accessory bundle.
Pros:- 20-cubic-foot capacity with listed dimensions of 51.1 × 39 × 17 inches.
- PVC-coated material and coated zippers are described as waterproof.
- Fits cars with or without roof racks.
- Includes six short straps, two long straps, an anti-slip mat, and a storage bag.
Cons:- Soft-sided construction provides less structure and impact protection than the D SOLUTIONS hard box.
- The listed accessories do not include a luggage lock or door hooks.
- Offers less capacity than the 28-cubic-foot RoofPax XXL.
Best for: Drivers who want a 20-cubic-foot soft carrier with clearly stated dimensions, waterproof materials, and a basic strap-and-mat setup.
Not ideal for: Buyers who want a hard shell, a listed luggage lock and door hooks, or the higher capacity of the RoofPax XXL.
- Capacity:20 cubic feet
- Dimensions:51.1 × 39 × 17 inches
- Weight:3.94 kg
- Material:PVC and nylon
- Water resistance:Waterproof
- Mounting:Roof mount
- Vehicle fit:Fits cars with or without roof racks
- Included accessories:Six short straps, two long straps, anti-slip mat, and storage bag
Our verdict“Pick MIDABAO for a plainly specified 20-cubic-foot waterproof soft bag, but look elsewhere for hard-shell protection or a lock-and-hook accessory set.”
D SOLUTIONS Hard Shell Rooftop Cargo Carrier, 11 Cubic Feet
The D SOLUTIONS stands apart from the other four picks by trading capacity for a rigid ABS hard shell. Its 11 cubic feet is well below the soft-sided MIDABAO’s 20 and RoofPax XXL’s 28, but a hard enclosure gives luggage more structure and impact shielding than a flexible bag. The box is listed as waterproof and includes a key lock, two keys, four mounting brackets, and hardware, so it suits buyers who prefer a fixed, lockable container over arranging straps and door hooks around a soft carrier.
The fit requirement is the main dividing line: this model requires crossbars, while the KMFurnila, MIDABAO, and RoofPax are designed to work with vehicles that lack roof racks. Its 50.3-pound weight also makes installation and removal a more involved task than handling the 3.9 kg Sailnovo bag. I’d choose it for rigid protection and a lockable shell, provided the vehicle has compatible crossbars and the reduced capacity is enough.
Pros:- ABS hard shell provides more structure and impact protection than the soft bags in this group.
- Waterproof design is intended to protect contents from weather.
- Includes a key lock, two keys, four mounting brackets, and mounting hardware.
- Listed 110-pound load capacity provides a defined cargo limit.
Cons:- Requires crossbars, unlike the soft carriers designed for vehicles with or without roof racks.
- 11-cubic-foot volume is substantially lower than the 20-cubic-foot bags and 28-cubic-foot RoofPax XXL.
- At 50.3 pounds, it is heavier to install and remove than the soft-shell alternatives.
Best for: Drivers with crossbars who carry luggage that benefits from a rigid, lockable enclosure and can manage a heavier carrier.
Not ideal for: Vehicles without crossbars, buyers who need more than 11 cubic feet, or anyone prioritizing a lightweight carrier that is easy to remove and store.
- Volume:11 cubic feet
- Dimensions:53 × 34 × 15 inches
- Weight:50.3 pounds
- Material:ABS plastic
- Load capacity:110 pounds
- Mounting requirement:Roof mount; requires crossbars
- Water resistance:Waterproof
- Included components:Cargo box, two keys, four mounting brackets, and mounting hardware
Our verdict“Choose the D SOLUTIONS box for rigid, lockable storage on a crossbar-equipped vehicle, but skip it if you need high volume or a lighter carrier.”
DUMOS Car Roof Bag Cargo Carrier – 15 Cubic Feet Waterproof Rooftop Storage
The DUMOS is a practical pick for drivers who want 15 cubic feet of soft-sided storage without first buying crossbars: its fit is listed for vehicles with or without roof racks, and the kit includes door hooks and reinforced straps. The anti-slip mat helps limit movement and reduce contact between the bag and the roof, while the lock adds a basic layer of security. Compared with the similarly sized Asinking 15-cubic-foot bag, DUMOS lists heavy-duty, tear-resistant PVC but supplies fewer installation details, so buyers seeking clearly specified accessories may prefer Asinking’s six door hooks and extra straps. The tradeoff is shared by soft bags generally: this carrier cannot shield cargo from hard impacts like a hard-shell box, and its straps and hooks need careful setup before driving.
Pros:- 15-cubic-foot capacity adds room for trip luggage.
- Designed to fit vehicles with or without roof racks.
- Includes an anti-slip mat, door hooks, reinforced straps, and a combination lock.
- Folds into the included storage bag between trips.
Cons:- Soft PVC offers less impact protection than a hard-shell carrier.
- Straps and hooks require careful installation to keep the bag stable at speed.
- The product details provide less specific mounting information than the Asinking 15-cubic-foot bag.
Best for: Drivers with a sedan, hatchback, or SUV who need occasional extra luggage space without roof racks.
Not ideal for: Travelers carrying fragile or impact-sensitive items, or anyone who wants a rigid carrier with less strap-dependent installation.
- Capacity:15 cubic feet
- Material:Heavy-duty PVC
- Compatibility:Sedan, SUV, truck, station wagon, hatchback, and hardtop crossover
- Roof rack requirement:Fits vehicles with or without roof racks
- Included components:Anti-slip mat, door hooks, luggage lock, reinforced straps, and storage bag
- Model number:TA-CDB4514-15-BY
- Brand:DUMOS
Our verdict“Choose the DUMOS for flexible, rack-free storage on occasional trips, but skip it if you need hard-shell protection.”
Asinking Waterproof Car Rooftop Cargo Carrier Bag, 15 Cubic Feet
Among the two 15-cubic-foot options here, the Asinking gives buyers a clearer picture of what arrives: the kit lists six door hooks, two extra straps, an anti-slip mat, and a luggage lock. Its 840D PVC fabric, reinforced welded seams, and zipper cover are aimed at keeping luggage dry, while the stated 44 x 34 x 17-inch dimensions make it easier to judge roof fit than the DUMOS listing. Both bags fit vehicles with or without roof racks; Asinking’s advantage is its more detailed accessory list and a two-year warranty. That does not remove the installation work: a soft carrier still relies on correctly routed straps and hooks, and the listing gives limited evidence about durability over extended use. Choose it for clarity and kit contents, not impact protection.
Pros:- 840D PVC fabric with reinforced welded seams and a waterproof zipper cover.
- Six door hooks and two extra straps provide a detailed securing kit.
- Fits vehicles with or without roof racks.
- Lists a two-year warranty and specific bag dimensions.
Cons:- Strap-and-hook installation takes care and needs checking before travel.
- Long-term durability is not detailed in the product information.
- The soft shell provides less protection from impacts than a rigid cargo box.
Best for: Drivers who want a 15-cubic-foot rooftop bag with a clearly listed mounting kit and stated warranty.
Not ideal for: Buyers seeking hard-shell protection, or drivers unwilling to fit and check several straps and door hooks.
- Capacity:15 cubic feet
- Dimensions:44 x 34 x 17 inches
- Material:840D PVC
- Water resistance:Waterproof
- Weight:3.99 kg
- Roof rack requirement:Fits vehicles with or without roof racks
- Included items:Storage bag, anti-slip mat, six door hooks, two extra straps, and luggage lock
- Warranty:2 years
Our verdict“Pick the Asinking over the DUMOS if a clearly itemized 15-cubic-foot kit and stated warranty matter more than a rigid shell.”
Car Roof Bag Rooftop Cargo Carrier – Waterproof 20 Cubic Feet
The MeeFar XBEEK offers a useful middle ground: 20 cubic feet gives it more room than the DUMOS and Asinking 15-cubic-foot bags, without moving up to the FIVKLEMNZ 30-cubic-foot carrier’s much larger footprint. Its 51 x 40 x 17-inch dimensions and rack-free fit make capacity and compatibility easier to judge, while the 700D PVC tarpaulin is described as waterproof and tear-proof. An anti-slip mat, security hooks, and lock are included, and the bag folds into its storage case after a trip. The tradeoff is that the supplied details do not specify as many individual mounting accessories as the Asinking 15-cubic-foot kit. At 3.9 kg, it also has more listed weight than that smaller Asinking bag, and first-time setup may take time.
Pros:- 20-cubic-foot capacity offers a middle option between 15- and 30-cubic-foot bags.
- Waterproof, tear-proof 700D PVC tarpaulin construction.
- Fits cars and SUVs with or without roof racks.
- Includes an anti-slip mat, security hooks, lock, and storage bag.
Cons:- At 3.9 kg, it is heavier than the Asinking 15-cubic-foot bag.
- Installation may take time, particularly for first-time users.
- The listed accessories are less specifically itemized than the Asinking 15-cubic-foot kit.
Best for: Travelers who outgrow 15-cubic-foot bags but do not need the extra bulk of a 30-cubic-foot carrier.
Not ideal for: Drivers with limited roof space, or anyone who wants a rigid carrier or a highly detailed list of mounting hardware.
- Capacity:20 cubic feet
- Dimensions:51 x 40 x 17 inches
- Material:700D PVC tarpaulin
- Water resistance:Waterproof
- Weight:3.9 kg
- Shell type:Soft automotive
- Roof rack requirement:Fits cars and SUVs with or without roof racks
- Included accessories:Anti-slip mats, lock, security hooks, and storage bag
Our verdict“Choose the MeeFar XBEEK if 15 cubic feet feels tight but the FIVKLEMNZ 30-cubic-foot bag is more capacity than you need.”
FIVKLEMNZ 21-Cubic-Foot Waterproof Soft Rooftop Cargo Carrier
This FIVKLEMNZ bag adds a little more room than the MeeFar XBEEK while keeping a more moderate footprint than the brand’s 30-cubic-foot version. Its 21-cubic-foot capacity, 840D PVC construction, welded seams, and double-layer waterproof cover suit travelers who need to move bulky luggage in wet-weather conditions. The mounting kit is also well specified: reinforced straps, six door hooks, an anti-slip mat, a lock, and a storage bag are included, and the bag fits vehicles with or without roof racks. Compared with the DUMOS, it offers more capacity and more stated seam and cover details. The compromises are weight and some uncertainty: it weighs 4.68 kg, the materials are listed as both PVC and Oxford cloth, and its soft shell needs careful securing at highway speeds.
Pros:- 21-cubic-foot capacity exceeds the MeeFar XBEEK’s 20 cubic feet.
- Welded seams and a double-layer cover are designed to protect cargo from rain and snow.
- Includes reinforced straps, six door hooks, an anti-slip mat, a lock, and a storage bag.
- Fits vehicles with or without roof racks.
Cons:- At 4.68 kg, it is heavier than the listed MeeFar XBEEK and Asinking 15-cubic-foot bag.
- Product details list both PVC and Oxford cloth, leaving the material description unclear.
- Soft construction depends on careful packing and secure strap installation at speed.
Best for: Families or road-trip travelers who need more than 20 cubic feet and want a detailed set of mounting accessories.
Not ideal for: Drivers with limited roof space, anyone prioritizing a light carrier, or buyers who need a single clearly specified fabric description.
- Capacity:21 cubic feet
- Dimensions:52 x 40 x 17 inches
- Weight:4.68 kg
- Material:840D PVC; product details also list Oxford cloth
- Water resistance:Waterproof
- Roof rack requirement:Fits vehicles with or without roof racks
- Included accessories:Anti-slip mat, reinforced straps, six door hooks, luggage lock, and storage bag
- Warranty:12 months
Our verdict“Pick this FIVKLEMNZ when 21 cubic feet and a full mounting kit matter more than low weight or a rigid shell.”
FIVKLEMNZ 30 Cubic Feet Waterproof Soft Rooftop Cargo Carrier
When the priority is moving the most gear in this group, the FIVKLEMNZ 30-cubic-foot bag has a clear advantage: its stated capacity is well above the 21-cubic-foot FIVKLEMNZ and the 20-cubic-foot MeeFar XBEEK. The 840D PVC, welded seams, and double-layer cover are intended to help keep luggage dry, and the package includes reinforced straps, six door hooks, an anti-slip mat, a lock, and a storage bag. Its rack-free fit also broadens the range of vehicles it can serve. That extra volume comes with real fit and handling questions. The supplied dimensions conflict—60 x 43 x 20 inches in the description versus 60 x 60 x 20 inches in item details—so roof compatibility is harder to confirm. At 5.44 kg, it is also the heaviest of these five soft bags, and careful packing and securing matter.
Pros:- 30-cubic-foot capacity is the largest among these five products.
- Welded seams and a double-layer cover are intended to help protect cargo from rain and snow.
- Fits vehicles with or without roof racks.
- Includes reinforced straps, six door hooks, an anti-slip mat, a lock, and a storage bag.
Cons:- Listed dimensions conflict between the description and item details.
- At 5.44 kg, it is heavier than the other bags in this group.
- The large soft bag needs careful packing and secure installation to stay stable.
Best for: Large families or travelers carrying bulky camping and vacation gear who have ample roof space and need maximum soft-bag capacity.
Not ideal for: Drivers with compact vehicles or limited roof space, and buyers who need confirmed dimensions before checking fit.
- Capacity:30 cubic feet
- Dimensions:60 x 43 x 20 inches in description; 60 x 60 x 20 inches in item details
- Weight:5.44 kg
- Material:840D PVC; Oxford cloth also listed
- Water resistance:Waterproof
- Mounting type:Strap mount
- Roof rack requirement:Fits vehicles with or without roof racks
- Included components:Anti-slip mat, storage bag, security lock, six door hooks, and reinforced straps
- Warranty:12 months
Our verdict“Choose this FIVKLEMNZ for maximum soft-bag capacity only if you can confirm its dimensions and have enough roof space.”
Asinking 21-Cubic-Foot Waterproof Rooftop Cargo Carrier Bag
The Asinking 21-cubic-foot bag combines generous capacity with a mounting setup that works on vehicles with or without roof racks. That flexibility gives it an advantage over the MeeFar Roof Rack Cargo Basket with Waterproof Bag, which requires crossbars, while the MeeFar provides a rigid basket and a higher stated load limit. Asinking uses 840D PVC, reinforced seams, and a zipper with protective flaps to help keep luggage dry. Its anti-slip mat, six padded door hooks, and extra straps provide useful pieces for securing a soft carrier, though setup still involves routing and tightening straps rather than simply mounting a hard box. At 21 cubic feet, it suits bulky trip gear, but buyers should check vehicle fit and follow the roof’s load limits.
Pros:- 21-cubic-foot capacity accommodates bulky luggage and trip gear
- 840D PVC, reinforced seams, and a covered waterproof zipper help protect cargo
- Can mount on vehicles with or without roof racks
- Includes an anti-slip mat, padded hooks, extra straps, and a storage bag
Cons:- Requires careful strap and door-hook installation
- Soft construction offers less structure than the SportRack Vista XL hard cargo box
Best for: Drivers without roof racks who need a high-capacity soft carrier for occasional road trips.
Not ideal for: Buyers who want quick, rigid-box access or would rather avoid fastening multiple straps and door hooks.
- Capacity:21 cubic feet
- Material:840D PVC
- Water resistance:Waterproof
- Dimensions:52 × 40 × 18 in
- Weight:4.24 kg
- Fit:Universal; compatible with vehicles with or without roof racks
- Mounting:Roof mount
- Included accessories:Anti-slip mat, 6 padded door hooks, 2 extra luggage straps, storage bag, luggage lock
Our verdict“Choose the Asinking if you need 21 cubic feet of weather-resistant storage and rack-free mounting flexibility, and accept the extra securing steps.”
SportRack Vista XL Rear-Opening Cargo Box, Black
The SportRack Vista XL is the hard-shell choice in this group, with an 18-cubic-foot ABS box and a rear opening that lets you reach cargo from behind the vehicle rather than leaning toward passing traffic. That access advantage separates it from the soft Asinking and TANX bags, which pack away for storage but rely on straps and fabric closures. Tool-free crossbar mounting, a key, and a lock make this a more structured option for drivers who want a fixed box for a trip. Its tradeoffs are fit and load limits: the Vista XL needs compatible crossbars spaced within the specified range and is rated for 100 pounds. It also weighs more and takes up storage space when removed, unlike a foldable bag.
Pros:- Rear opening places access away from roadside traffic
- UV-resistant ABS plastic forms a rigid cargo enclosure
- Tool-free crossbar mounting simplifies installation and removal
- Includes a key and lock
Cons:- Requires compatible crossbars within the specified spacing range
- 100-pound maximum load may limit heavier gear
- Rigid box is less convenient to store than a soft carrier when not in use
Best for: Drivers with compatible crossbars who want a lockable hard box and rear access for loading away from traffic.
Not ideal for: Drivers without crossbars, those carrying loads above 100 pounds, or anyone needing a carrier that folds away between trips.
- Storage capacity:18 cu ft (510 L)
- Material:UV-resistant ABS plastic
- Opening:Rear-opening
- Dimensions:63 × 38 × 19 in
- Weight capacity:100 lb (45 kg)
- Crossbar spacing:23 5/8–29 3/4 in (60–75.5 cm)
- Mounting:Tool-free crossbar mount
- Warranty:25 years
Our verdict“Pick the Vista XL if your crossbars fit and you value a rigid, rear-opening box over the packability of the Asinking or TANX soft bags.”
MeeFar Roof Rack Cargo Basket with Waterproof Bag, 65 x 39 x 6 in
The MeeFar basket-and-bag set is the most adaptable cargo platform here: its epoxy-coated steel basket can carry exposed gear, while the included 20-cubic-foot waterproof bag gives luggage a covered option. The cargo net and ratchet straps add ways to secure differently shaped loads, unlike the enclosed SportRack Vista XL, which is better suited to cargo that fits inside a box. The basket can also be shortened from its full assembly length, giving buyers some flexibility with rack space. The main constraint is vehicle hardware: it mounts with four U-bolts to crossbars, so it is not a rack-free solution like the Asinking or FIVKLEMNZ soft bags. Its stated 200-pound capacity is also subject to the vehicle roof’s lower limit, if applicable.
Pros:- Combines a steel basket with a 20-cubic-foot waterproof bag
- Cargo net and ratchet straps help secure varied or irregular loads
- Epoxy-coated alloy-steel construction
- Assembly can be shortened to 45 inches
Cons:- Requires vehicle crossbars and four U-bolt mounting points
- The vehicle roof limit may be lower than the basket’s 200-pound capacity
- Basket and tie-down setup is less streamlined than using a standalone soft bag
Best for: Crossbar-equipped drivers who carry a mix of covered luggage and awkward gear that benefits from a basket, net, and ratchet straps.
Not ideal for: Drivers without crossbars or those who want a simple, enclosed carrier without basket assembly and additional tie-downs.
- Basket dimensions:65 × 39 × 6 in
- Short assembly length:45 in
- Load capacity:200 lb
- Cargo bag capacity:20 cu ft
- Material:Alloy steel
- Mounting:Roof mount with four universal U-bolts
- Fit:Universal; requires vehicle crossbars
- Included accessories:Waterproof bag, cargo net with hooks, ratchet straps, combination lock
Our verdict“Choose MeeFar if you already have crossbars and want a flexible basket-and-bag setup for cargo that a closed box cannot handle as easily.”
TANX Car Roof Bag – 21 Cu Ft Waterproof Rooftop Cargo Carrier with Anti-Slip Mat, 12 Straps, 6 Door Hooks, and Lock
The TANX 21-cubic-foot bag makes the most sense for buyers who want a large, rack-optional carrier with a broad set of installation accessories. It fits cars and SUVs with or without roof racks and includes an anti-slip mat, reinforced straps, door hooks, and a combination lock. Compared with the Asinking 21-cubic-foot bag, TANX has nearly the same listed capacity and footprint, but uses 500D PVC tarpaulin rather than 840D PVC; Asinking’s material specification may appeal more to buyers prioritizing heavier-denier fabric. TANX’s sealed seams and waterproof claim address wet-weather protection, but first-time users may need time to position the mat and tighten the straps evenly. The soft design is easier to stow than the SportRack Vista XL, though it does not offer the same rigid enclosure.
Pros:- 21-cubic-foot capacity fits substantial luggage and trip gear
- Sealed seams and waterproof construction are suited to wet-weather travel
- Fits vehicles with or without roof racks
- Includes an anti-slip mat, straps, hooks, combination lock, and storage bag
Cons:- First-time installation can take time while the straps are positioned and tightened
- Uses 500D PVC tarpaulin, while the Asinking bag lists 840D PVC
- Soft sides do not provide the rigid structure of the SportRack Vista XL
Best for: Car and SUV owners who need a large soft carrier with an all-in-one kit and may not have roof racks.
Not ideal for: Buyers who prioritize a higher-denier fabric specification or want a quick-access rigid box instead of strap-based installation.
- Capacity:21 cubic feet
- Dimensions:52 × 40 × 17 in
- Weight:4.25 kg
- Material:500D PVC tarpaulin
- Water resistance:Waterproof with sealed seams
- Fit:Universal fit for cars and SUVs, with or without a roof rack
- Mounting:Roof mount
- Included accessories:Anti-slip mat, straps, door hooks, combination lock, storage bag
Our verdict“Choose TANX for a rack-optional, high-capacity soft bag with a full installation kit, but compare its 500D fabric with Asinking’s 840D construction.”
FIVKLEMNZ Waterproof Rooftop Cargo Carrier Bag, 15 cu ft
At 15 cubic feet, this FIVKLEMNZ bag is the compact choice among the soft carriers in this batch. Its smaller 46 × 34-inch footprint can suit drivers who need extra room for a few bags but do not want the larger rooftop area of the 21-cubic-foot Asinking or TANX. The 840D PVC, welded seams, and double-layer cover provide a substantial weather-protection package on paper, while the included anti-slip mat and eight reinforced straps help secure it on vehicles with or without roof racks. The reduced capacity is the clear tradeoff: families packing several suitcases may be better served by the Asinking, which offers six more cubic feet. Like other soft bags, this one also takes hands-on strap and hook work to install.
Pros:- Compact 15-cubic-foot size takes less rooftop space than the 21-cubic-foot Asinking
- 840D PVC, welded seams, and a double-layer cover help protect luggage from water
- Fits vehicles with or without roof racks
- Includes an anti-slip mat, eight reinforced straps, door hooks, lock, and storage bag
Cons:- Less capacity than the Asinking and TANX 21-cubic-foot bags
- Multiple straps and door hooks require careful installation
- Soft construction does not provide the rigid shape of the SportRack Vista XL
Best for: Drivers with modest extra cargo who want a smaller-footprint soft bag that can mount with or without roof racks.
Not ideal for: Families carrying several suitcases or bulky camping gear who are likely to need more than 15 cubic feet.
- Capacity:15 cubic feet
- Dimensions:46 × 34 × 17 in
- Weight:6.6 lb
- Material:840D PVC
- Water resistance:Waterproof; welded seams and double-layer cover
- Fit:Universal; vehicles with or without roof racks
- Mounting:Roof mount
- Included accessories:Anti-slip mat, 8 reinforced straps, 6 door hooks, luggage lock, storage bag
Our verdict“Choose this FIVKLEMNZ when a smaller rooftop footprint matters more than the extra capacity offered by the Asinking or TANX.”
How We Picked
I compared these 15 vehicle rooftop cargo carriers by the decisions that most affect day-to-day ownership: stated capacity, soft-bag versus hard-box or basket design, weather protection claims, attachment approach, and likely ease of loading and storage. I also looked for details that separate near-capacity matches, such as the TANX bag’s included mat, straps, hooks, and lock, or the SportRack Vista XL’s rear-opening access. Product names and stated specifications establish the comparison; I do not treat them as proof of performance under every vehicle, load, or weather condition.
The ranking favors options with a clear use case and a useful balance of capacity, format, and practical setup. RoofPax leads for buyers needing substantial soft-sided storage; the Vista XL ranks highly for a rigid box preference; and the D SOLUTIONS carrier earns a place for drivers who want a smaller hard shell. The 15- to 21-cubic-foot bags remain useful alternatives, but their similar capacity makes fit, attachment details, and included equipment more important. I place the basket-and-bag setup in a separate niche because its open frame changes how cargo is supported and packed.

Factors to Consider When Choosing Vehicle Rooftop Cargo Carriers
Before choosing by capacity alone, I’d match the carrier to the vehicle, the gear, and how often it will be installed or removed. These broader checks can prevent fit problems and help you decide whether a soft bag, hard box, or basket setup makes sense.
Match the carrier to the roof setup
Start with the vehicle’s roof and the carrier’s attachment method, not the product’s capacity. A model that relies on crossbars may not work as intended on a roof without them, while door-hook systems need compatible door frames and weather seals. Check the vehicle and carrier instructions for permitted mounting points and load limits before buying. The roof’s limit can be lower than the carrier’s advertised capacity, and that limit usually includes the carrier itself. Avoid assuming that a universal label means a universal fit; confirm the exact vehicle configuration and hardware requirements.
Choose capacity around real cargo, not a headline number
Cubic feet describe volume, but they do not tell you whether a carrier can hold a particular item’s shape or weight. Bulky sleeping bags may fit a soft bag well, while rigid cases or awkward equipment can be harder to arrange and secure. Before choosing between a 15-, 21-, 28-, or 30-cubic-foot option, list the items you intend to move and check their dimensions. Leave room to close the carrier without forcing zippers, flaps, or closures. A larger bag is not automatically a better buy if it encourages an unstable or poorly balanced load.
Decide how much structure and access you need
Soft bags can fold down for storage and adapt to different loads, but they need careful packing and attachment. A hard box gives cargo a rigid enclosure and can make loading feel more structured, though it takes more space to store when removed. Rear-opening designs such as the SportRack Vista XL can suit drivers who load from behind the vehicle, but access depends on parking space and vehicle layout. A basket with a bag adds an open support frame, which may suit cargo that benefits from a base but creates more pieces to manage. Pick the format based on your loading habits and garage or storage space, not just exterior appearance.
Treat weather protection as a setup issue too
A waterproof claim does not remove the need to close every flap, zipper, and cover correctly. Soft carriers can be vulnerable to water entering through closures or to contents pressing against seams when packed too tightly. Use internal waterproof bags for items that cannot get wet, even when the outer carrier is marketed as waterproof. Check that the load will not block closures or rub against the roof, and inspect attachment points before a long drive. If your cargo needs a consistently rigid barrier, compare a hard box with a soft bag rather than relying on a label alone.
Account for installation, removal, and storage
A carrier used for one annual trip has different priorities from one fitted regularly. Soft bags are generally easier to fold away, but straps and hooks still need to be organized and checked each time. Hard boxes and baskets may be more cumbersome to store, even if their loading structure suits frequent use. Look at what hardware comes with the product and whether it fits your roof; included straps or hooks are only useful when they match the vehicle. If one person will install the carrier, favor a setup whose weight, attachment steps, and storage demands are manageable for that person.
Balance roof load, driving, and cargo security
Every rooftop load changes how a vehicle handles, so respect both the vehicle’s roof limit and the carrier maker’s instructions. Keep heavier items low and distribute weight evenly instead of piling everything to one side or at the front. Secure loose contents inside the carrier so they cannot shift under braking or cornering. A lock can deter casual access, but it should not be treated as a substitute for sound attachment or a guarantee against theft. Recheck straps and closures after loading and during stops, especially when a soft carrier’s contents may settle on the road.
Frequently Asked Questions
Can I use a rooftop cargo bag without roof crossbars?
Some soft bags use door hooks or other attachment points and may work without crossbars, but compatibility varies by model and vehicle. Check the instructions for the exact attachment method and confirm that your roof and door frames provide approved mounting points. Do not assume a bag that includes hooks will fit every vehicle, or that a bare roof can safely support its loaded weight. If the carrier requires crossbars, adding a different attachment method may not be safe or supported. When fit guidance is unclear, confirm it with the manufacturer before loading the vehicle.
Should I choose a soft rooftop bag or a hard cargo box?
I’d choose a soft bag if fold-away storage and flexible capacity matter most, particularly for occasional trips. A hard box such as the SportRack Vista XL is a better match for buyers who prefer a rigid enclosure and rear-opening access, provided they have room to store it off the vehicle. Neither format removes the need to check roof limits, attachment fit, or closure instructions. Soft bags demand careful packing and strap checks, while hard boxes can be bulky to handle and store. Let your storage space and cargo type decide the format before comparing capacity.
Is a 28- or 30-cubic-foot carrier too large for a typical trip?
It may be more capacity than a typical trip requires, but volume alone does not determine whether a carrier is suitable. The loaded weight must stay within the vehicle’s roof limit, and the carrier must fit its approved mounting setup. A large soft bag also needs a load that can be arranged without obstructing closures or shifting during travel. If you usually carry a modest amount of luggage, a 15- to 21-cubic-foot option may be easier to manage. Choose the larger RoofPax or FIVKLEMNZ size only when your cargo list justifies the added space.
Can I leave a rooftop carrier on my vehicle year-round?
Check the carrier and vehicle instructions before leaving any loaded or empty carrier installed for extended periods. Weather exposure, wind, and regular driving can affect the carrier and its attachment points, and a soft bag may be less suited to long-term exposure than occasional trip use. Leaving a carrier mounted also adds height and can affect vehicle handling and access to garages or parking structures. Remove and store it when it is not needed if the maker’s guidance calls for that or if the setup cannot be regularly checked. Reinspect the material and attachments before the next trip.
How do I decide between the similar 15- to 21-cubic-foot soft bags?
First check vehicle fit and attachment requirements; a capacity match is not useful if the bag cannot be secured to your roof. Then compare the included equipment and design details rather than assuming bags with similar volume perform the same way. The TANX listing includes an anti-slip mat, multiple straps, door hooks, and a lock, while other options may suit buyers seeking a simpler bag. Confirm whether those accessories are compatible with your vehicle and whether they address a need you actually have. Also compare the stated dimensions with the cargo you plan to carry, since volume figures do not describe the usable shape.
Conclusion
My best overall choice is the RoofPax XXL 28-Cubic-Foot bag for drivers who need substantial soft-sided space; the SportRack Vista XL is my best premium-style pick for buyers who prefer a rigid, rear-opening box. For best value in practical capacity, compare the 15- to 21-cubic-foot bags by vehicle fit and included hardware, with the TANX a standout when its supplied accessories suit your setup. The best choice for beginners is a carrier whose attachment instructions match the vehicle and whose capacity leaves room for easy, balanced loading—not simply the largest option. For specific needs, pick the D SOLUTIONS hard shell for a smaller rigid carrier or the MeeFar basket-and-bag setup for its distinct frame-supported format. Check your roof limits and fit before choosing, then let cargo shape and storage space settle the final decision.
