Among these roof cargo boxes, the Thule Pulse 2 L is my best overall pick for its 16-cubic-foot capacity and dual-side access. The Thule Force 3 XL is the premium choice, while the FIVKLEMNZ 21-cubic-foot bag offers a flexible option for bulky loads. The main tradeoffs are hard-shell security and shape retention versus the lower storage demands of soft bags, as well as cargo capacity versus vehicle fit and handling. The right choice depends on your roof, crossbars, gear, and how often you’ll mount or store the carrier. Read on for the full comparison and a guide to choosing a setup that suits your trips.

Key Takeaways
- The lineup splits into two distinct types: hard-shell boxes offer a structured, lockable enclosure, while soft bags such as the FIVKLEMNZ and Asinking provide high stated capacity without a rigid shell.
- The Thule Pulse 2 L leads the all-round group with 16 cubic feet and dual-side opening; its 14-cubic-foot M version is a better fit when roof space or cargo needs are more modest.
- The biggest capacity figures belong to soft bags: the 21-cubic-foot FIVKLEMNZ and Asinking models suit bulky loads, but their format differs from a rigid, lockable box.
- Rear-opening design changes loading access: the SportRack Vista XL opens at the rear, which can be useful when side access is restricted, but it is not the same convenience as dual-side access.
- Smaller hard-shell options trade volume for a more compact footprint: the 11-cubic-foot D SOLUTIONS box and 12-cubic-foot GarveeTech can suit lighter packing needs, while the larger options need more careful vehicle-fit checks.

More Details on Our Top Picks
Thule Pulse 2 L Roof-Mounted Cargo Box, 16 cu. ft., Dual-Side Opening
The Thule Pulse 2 L pairs generous 16-cubic-foot capacity with access from either side, which helps when the vehicle is parked close to a wall or roadside access is inconvenient. Its tool-free mount with a torque indicator also gives clearer feedback during installation than a system relying only on tightening by feel. The forward mounting position is intended to preserve trunk access, a practical advantage over bulky boxes that can obstruct a rear hatch. Compared with the SportRack Vista XL, this Thule offers dual-side access rather than a rear-only opening, but the SportRack has more listed volume. The major caveat is its stated lack of water resistance; I would not choose it for gear that must stay dry in rain without separate protection. Check the vehicle and rack limits against its 75 kg capacity before loading.
Pros:- 16 cubic feet of storage suits luggage and outdoor gear.
- Dual-side opening gives access from either side of the vehicle.
- Tool-free mounting system includes a torque indicator.
- Forward positioning is designed to preserve trunk access.
Cons:- Listed as not water resistant, limiting confidence in wet-weather cargo protection.
- Its 75 kg load capacity still needs to be checked against the vehicle and roof-rack limits.
Best for: Drivers who want a large hard box, two-sided access, and a tool-free mounting system for frequent loading.
Not ideal for: Travelers carrying moisture-sensitive luggage in wet weather, since the product data lists it as not water resistant.
- Volume:450 liters (16 cu. ft.)
- Load capacity:75 kg
- Opening:Dual-side
- Material:ASA-ABS plastic
- Dimensions:81 x 17 x 37 in
- Mounting:Roof mount; tool-free system with torque indicator
- Water resistance:Not water resistant
- Warranty:Limited lifetime
Our verdict“Choose the Thule Pulse 2 L for spacious, convenient two-sided access, but skip it if weather protection is your main requirement.”
GarveeTech Rooftop Cargo Box Carrier with Dual-Side Opening
The GarveeTech Rooftop Cargo Box is a hard-shell choice for drivers who put waterproof protection ahead of maximum capacity. Its 14 cubic feet are less than the 16 cubic feet in the Thule Pulse 2 L, but the GarveeTech explicitly lists a waterproof, UV-resistant ABS shell—an important distinction beside the Thule’s stated lack of water resistance. Dual-sided opening makes it easier to reach cargo from either side, while the included keys and straps provide basic security and cargo restraint. The tradeoff is that compatibility is limited to vehicles equipped with roof racks, so buyers should verify their rack setup before ordering. The product also specifies that one side must be locked while opening the other, which makes access less flexible than the simple phrase “dual-sided” might suggest.
Pros:- Waterproof, UV-resistant ABS shell is suited to wet-weather travel.
- Dual-sided opening offers access from either side of the vehicle.
- Includes two keys and two securing straps.
- 14 cubic feet provides useful hard-shell storage.
Cons:- Requires a compatible roof rack, which buyers must verify before purchase.
- One side must be locked when opening the other.
- Offers less capacity than the 16-cubic-foot Thule Pulse 2 L and 18-cubic-foot SportRack Vista XL.
Best for: Roof-rack owners who need a waterproof hard box for road trips and value access from either side.
Not ideal for: Drivers without roof racks, or those who want the largest listed capacity in this group; the Thule Pulse 2 L holds more.
- Storage capacity:14 cubic feet
- Maximum load capacity:165 lbs
- Material:ABS
- Dimensions:62.2 × 31.5 × 13.4 in
- Item weight:44.8 lbs
- Opening:Dual-sided
- Water resistance:Waterproof
- Fit:Universal; for vehicles with roof racks
- Warranty:1 year
Our verdict“Pick the GarveeTech if you have a compatible rack and want an explicitly waterproof hard box with two-sided access.”
SportRack Vista XL Rear-Opening Cargo Box
The SportRack Vista XL offers the most listed capacity among these hard boxes at 18 cubic feet, making it a sensible pick for bulky trip gear when storage volume matters more than side access. Its rear-opening lid keeps loading and unloading away from roadside traffic, while the tool-free crossbar mount can make installation and removal less involved. Compared with the dual-side-opening Thule Pulse 2 L, the Vista XL provides more space but gives up access from the vehicle’s sides. It also has a 100 lb load limit, so its volume should not be mistaken for permission to carry heavier gear. Compatibility depends on bar type and spacing; checking the stated crossbar range against the vehicle is part of the buying decision. Its 25-year warranty is a notable listed advantage, though the product data does not specify water resistance.
Pros:- 18 cubic feet is the largest capacity among the hard boxes in this batch.
- Rear opening keeps access away from roadside traffic.
- Tool-free crossbar mounting supports easier installation and removal.
- Includes a lock and key and lists a 25-year warranty.
Cons:- 100 lb maximum load capacity may limit dense or heavy cargo.
- Rear-only opening lacks the side access offered by the Thule Pulse 2 L and GarveeTech.
- Crossbar type and spacing must match, and water resistance is not specified.
Best for: Travelers with compatible crossbars who need high-volume hard-shell storage and prefer loading from the rear.
Not ideal for: Drivers who need side access or who cannot confirm compatible crossbar spacing; the Thule Pulse 2 L offers two-sided access.
- Capacity:18 cubic feet (510 L)
- Load capacity:100 lb (45 kg)
- Opening:Rear
- Material:UV-resistant ABS plastic
- Dimensions:63 x 38 x 19 in
- Crossbar spacing:23 5/8–29 3/4 in (60–75.5 cm)
- Compatibility:SportRack systems, square bars, round bars, and most factory racks
- Mounting:Tool-free crossbar mount
- Warranty:25 years
Our verdict“Choose the Vista XL for maximum hard-box volume and rear access, provided your crossbars fit and its load limit suits your gear.”
FIVKLEMNZ Waterproof Rooftop Cargo Carrier Bag, 15 cu ft
The FIVKLEMNZ 15-cubic-foot bag is the most adaptable fit in this group: its stated compatibility includes vehicles with or without roof racks. That makes it a practical alternative to hard boxes such as the SportRack Vista XL, which depends on compatible crossbars. The 840D PVC body, welded seams, and double-layer cover are aimed at protecting luggage from rain and snow, while the included mat, straps, and door hooks give buyers the pieces needed to secure it. The compromise is a more involved setup: multiple straps and hooks take more attention than a tool-free hard-box mount. Its soft shell also cannot provide the same impact protection as the ABS and ASA-ABS boxes. I’d favor it for occasional travel and flexible fit, not for cargo that needs a rigid enclosure.
Pros:- Designed to fit vehicles with or without roof racks.
- Waterproof 840D PVC construction includes welded seams and a double-layer cover.
- 15 cubic feet accommodates a useful amount of travel gear.
- Includes an anti-slip mat, reinforced straps, door hooks, a luggage lock, and storage bag.
Cons:- Securing the multiple straps and hooks takes more setup than a hard box mount.
- Soft-shell construction offers less impact protection than rigid cargo boxes.
Best for: Travelers who need 15 cubic feet of weather-protected storage and may not have roof crossbars.
Not ideal for: People who want rigid impact protection or a quick, simple mounting process; a hard box such as the GarveeTech is a better fit.
- Capacity:15 cubic feet
- Dimensions:46 x 34 x 17 in
- Weight:6.6 pounds
- Material:840D PVC
- Water resistance:Waterproof; welded seams and double-layer cover
- Fit:Universal; vehicles with or without roof racks
- Included accessories:Anti-slip mat, 8 reinforced straps, 6 door hooks, luggage lock, storage bag
Our verdict“Choose this bag when broad vehicle compatibility and flexible waterproof storage matter more than a rigid shell or fast setup.”
D SOLUTIONS Hard Shell Rooftop Cargo Carrier, Waterproof, 11 Cubic Feet
The D SOLUTIONS Hard Shell Carrier suits buyers who want a rigid, waterproof enclosure without moving up to a large roof box. Its 11-cubic-foot capacity is smaller than the 14-cubic-foot GarveeTech and the 18-cubic-foot SportRack Vista XL, but the more compact size may be easier to match to a shorter cargo list. A 110 lb load capacity and keyed lock add useful utility, and the included brackets and mounting hardware mean the main mounting pieces come with the box. Unlike the FIVKLEMNZ soft bag, this carrier offers a hard shell for impact protection; unlike that bag, it requires vehicle crossbars. At 50.3 pounds, it is also a substantial object to lift onto the roof. Choose it for compact, weather-protected hard-shell storage, not for maximum capacity or rack-free flexibility.
Pros:- Waterproof ABS shell protects cargo in wet conditions.
- Compact 11-cubic-foot capacity suits smaller cargo loads.
- 110 lb load capacity is specified.
- Includes a keyed lock, four mounting brackets, and mounting hardware.
Cons:- Requires vehicle crossbars.
- At 50.3 pounds, it may be awkward for one person to lift onto the roof.
- Offers less storage volume than the GarveeTech and SportRack hard boxes.
Best for: Drivers with crossbars who need a waterproof hard box for a smaller set of bags and value a keyed lock.
Not ideal for: Roof-rack-free vehicle owners or families needing high volume; the FIVKLEMNZ bag fits vehicles without racks, while the SportRack holds more.
- Volume:11 cubic feet
- Load capacity:110 pounds
- Material:ABS plastic
- Dimensions:53 x 34 x 15 in
- Weight:50.3 pounds
- Water resistance:Waterproof
- Mounting:Roof mount; requires crossbars
- Included components:Cargo box, pair of keys, 4 mounting brackets, mounting hardware
Our verdict“Pick the D SOLUTIONS box for compact, waterproof hard-shell storage if your vehicle has crossbars and you can manage its weight.”
Thule Force 3 XL Rooftop Cargo Box
The Force 3 XL earns this spot for buyers who want a hard box that is easy to reach from either side of the car. Its dual-side access is more convenient in tight parking spaces than a carrier with access from only one end, while the mounting indicator and SlideLock closure confirmation give clearer feedback during setup and closing. At 18 cubic feet, it also offers more room than the Thule Pulse 2 M, making it a better match for bulky family luggage. The tradeoff is its long 89-inch profile, which may affect vehicle clearance and access to a garage. The listing also uses conflicting Force 3 and Force XT model names, so I would verify the exact model before ordering.
Pros:- Dual-side access makes loading easier when one side of the vehicle is blocked.
- Mounting system signals when the box is securely attached.
- SlideLock indicates when the lid is closed and locked.
- 18-cubic-foot capacity exceeds the Thule Pulse 2 M’s 14 cubic feet.
Cons:- The 89-inch length may be awkward on shorter vehicles and can affect garage clearance.
- Requires a compatible roof mounting setup.
- Conflicting Force 3 and Force XT model references make the exact listing identity worth checking.
Best for: Drivers who regularly load luggage from either side and want a large hard box with clear mounting and closure indicators.
Not ideal for: Drivers with limited roof space, low garage clearance, or uncertainty about which Force model the listing describes.
- Volume:18 cu ft
- Dimensions:89 × 18 × 40 in
- Material:Plastic
- Water resistance:Water resistant
- Access:Both sides
- Mounting:Roof mount
- Fit:Universal
- Warranty:Limited lifetime
Our verdict“Choose the Force 3 XL for roomy, easy-to-access hard-shell storage, but confirm the model and check roof and garage clearance first.”
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 cu. ft., Dual-Side Opening
The Thule Pulse 2 M is the practical pick for buyers who want a hard cargo box without moving up to an extra-large carrier. Its tool-free mounting system uses a torque indicator and closure confirmation, helping make installation and closing less guesswork-heavy. The 14-cubic-foot capacity and 75 kg load limit suit luggage, skis, and everyday travel gear, while dual-side opening helps when parking access is tight. Compared with the larger Thule Force 3 XL, it gives up four cubic feet of storage but should be easier to accommodate when a long box would be cumbersome. It still needs a compatible roof rack, and its medium capacity may fall short for families packing bulky gear for an extended trip.
Pros:- Tool-free mounting system includes a torque indicator and closure confirmation.
- Dual-side opening gives access from either side of the vehicle.
- 75 kg load capacity accommodates a range of luggage and gear.
- Designed to allow full trunk access.
Cons:- Requires a compatible roof rack.
- 14 cubic feet is less capacity than the Thule Force 3 XL.
- Adds roof-mounted bulk and height to the vehicle.
Best for: Drivers with a compatible roof rack who want a medium-capacity hard box and a guided, tool-free mounting process.
Not ideal for: Large families or travelers carrying bulky equipment who need more room than 14 cubic feet can provide.
- Volume:400 liters (14 cu ft)
- Load capacity:75 kg
- Material:ASA-ABS plastic
- Opening:Dual-side
- Mounting:Roof mount; tool-free system
- Fit:Universal fit; compatible roof rack required
- Color:Black
- Warranty:Limited lifetime
Our verdict“Pick the Pulse 2 M if manageable capacity and guided, tool-free mounting matter more than the extra space of the Force 3 XL.”
GarveeTech Rooftop Cargo Box, 12 Cubic Feet, Dual-Side Opening, Black
The GarveeTech 12-cubic-foot box suits drivers who want enclosed hard-shell storage without committing to a larger carrier. Its waterproof, UV-resistant ABS shell is designed to shield packed gear from weather and sun, and opening from either side makes access less dependent on how the car is parked. Compared with the 17-cubic-foot Maxsa Innovations box, this one sacrifices substantial capacity but has a shorter 54.3-inch length, which may be easier to fit on vehicles where roof space is limited. Its 165-pound maximum load is useful, but that figure does not remove the need to follow the vehicle and roof-rack limits. It requires a roof rack, and buyers should check mounting compatibility before choosing it.
Pros:- Waterproof, UV-resistant ABS shell protects gear from weather exposure.
- Dual-sided opening makes loading practical from either side.
- 165-pound maximum load capacity, subject to vehicle and rack limits.
- Includes two keys and two securing straps.
Cons:- 12 cubic feet holds less than the Maxsa Innovations 17-cubic-foot box.
- Requires a roof rack, and compatibility should be checked before purchase.
- At 39 pounds, it adds notable weight before any cargo is loaded.
Best for: Drivers with a roof rack and limited roof space who need weather-protected storage for a moderate amount of luggage.
Not ideal for: Travelers who need family-size capacity or whose roof rack compatibility cannot be confirmed.
- Capacity:12 cu ft (340 L)
- Maximum load:165 lb
- Dimensions:54.3 × 31.5 × 13.4 in
- Weight:39 lb
- Material:ABS
- Water resistance:Waterproof
- Opening:Dual-sided
- Warranty:One year
Our verdict“Choose the GarveeTech when compact hard-shell storage and weather protection matter more than the capacity of a larger carrier.”
FIVKLEMNZ 21-Cubic-Foot Waterproof Soft Roof Cargo Bag
The FIVKLEMNZ soft cargo bag is the flexible choice for drivers who need substantial storage but do not have a roof rack. Its listing says it fits vehicles with or without racks and includes door hooks, reinforced straps, and an anti-slip mat, giving buyers more of the securing kit than the hard-shell boxes offer. At 21 cubic feet, it also holds more than the Thule Force 3 XL, though a soft bag does not provide the same impact protection as a rigid shell. Welded seams and 840D PVC are intended to help keep luggage dry, but the listed materials also mention Oxford cloth, so construction details are less straightforward. Expect a more involved installation: multiple straps and door hooks take more attention than a rigid box’s mounting system.
Pros:- 21-cubic-foot capacity exceeds the Thule Force 3 XL’s listed 18 cubic feet.
- Designed for vehicles with or without roof racks.
- Welded seams and 840D PVC are specified to help keep contents dry.
- Includes an anti-slip mat, reinforced straps, door hooks, luggage lock, and storage bag.
Cons:- Soft construction offers less impact protection than a hard-shell box.
- Securing the bag involves multiple straps and door hooks.
- The product data lists both PVC and Oxford cloth, leaving some material detail unclear.
Best for: Occasional road trippers who need high capacity and a carrier designed to attach with or without a roof rack.
Not ideal for: Drivers who want rigid impact protection, quick installation, or a hard enclosure for fragile cargo.
- Capacity:21 cu ft
- Dimensions:52 × 40 × 17 in
- Weight:4.68 kg
- Material:840D PVC; Oxford cloth also listed
- Water resistance:Waterproof; welded seams
- Fit:Vehicles with or without roof racks
- Included accessories:Anti-slip mat, 10 reinforced straps, 6 door hooks, luggage lock, storage bag
- Warranty:12 months
Our verdict“Pick this bag for flexible, high-capacity travel storage when rack-free mounting matters more than rigid protection and fast setup.”
Maxsa Innovations Hard-Shell Rooftop Cargo Box, 17 cu ft, 165 lb Capacity
The Maxsa Innovations hard-shell box offers a useful middle ground for buyers who want more room than the compact GarveeTech without stepping up to the 18-cubic-foot Thule Force 3 XL. Its 17-cubic-foot capacity and 165-pound listed weight capacity suit luggage and general travel gear, while a waterproof ABS shell and dual-side opening make it more protective and accessible than the FIVKLEMNZ soft bag. The included straps, installation components, lock, and two keys provide a ready-to-fit package, though the listing describes strap mounting and also calls for a compatible roof rack. I would confirm the intended attachment method and rack fit before buying. Its 35.3-pound empty weight also counts toward the vehicle’s roof load limit.
Pros:- 17 cubic feet offers more space than the GarveeTech 12-cubic-foot box.
- Waterproof ABS shell provides rigid protection for packed gear.
- Dual-side opening helps with loading from either side of the vehicle.
- Includes straps, a security lock, and two keys.
Cons:- Roof-rack compatibility and the stated strap mounting method should be verified.
- 35.3-pound item weight adds to the vehicle’s roof load before cargo.
- Offers slightly less capacity than the Thule Force 3 XL.
Best for: Drivers with a compatible roof rack who want a roomy hard box with dual-side access and included locking hardware.
Not ideal for: Buyers seeking rack-free mounting, a low-weight carrier, or installation details that are unambiguous before purchase.
- Capacity:17 cu ft
- Weight capacity:165 lb
- Dimensions:55.12 × 35.04 × 16.14 in
- Item weight:35.3 lb
- Material:Waterproof ABS shell
- Opening:Dual-side
- Mounting:Strap; compatible roof rack specified
- Included components:Security lock, straps, two keys
Our verdict“Choose the Maxsa for substantial hard-shell storage and dual-side access if its mounting method matches your rack and vehicle.”
VISRACK Roof Cargo Box, 14 Cubic Feet, Dual-Side Opening
I’d shortlist the VISRACK B-62 for drivers who want hard-shell storage but need flexibility when loading from either side of the car. Its 14-cubic-foot capacity matches the Thule Pulse 2 M, while dual-side access can be more convenient when parking beside a wall or loading from the curb. Tool-free mounting and compatibility with round, square, and aerodynamic crossbars also make it adaptable across many roof-rack setups.
The tradeoff is fit verification: the mounting-hole spacing must fall between 17.32 and 38.58 inches, so “many crossbars” does not mean every setup. Its low profile may also rule out taller luggage, and the stated 30-day warranty offers less coverage than some buyers may want. I’d choose it for flexible access, not for unusually bulky cargo.
Pros:- Dual-side opening makes loading easier from either side of the vehicle.
- 14 cubic feet of storage with a 150-pound maximum load.
- Tool-free mounting is specified for round, square, and aerodynamic crossbars.
- ABS composite shell is designed to protect cargo from weather and road debris.
Cons:- Mounting-hole spacing must be checked against the vehicle’s crossbars before purchase.
- Low-profile shape may not fit taller luggage or other bulky cargo.
- 30-day warranty provides a limited stated coverage period.
Best for: Drivers with compatible crossbars who want 14 cubic feet of weather-protective hard-shell storage and access from either side.
Not ideal for: Travelers carrying tall, bulky items or owners who cannot confirm that their crossbar spacing matches the box’s mounting range.
- Brand:VISRACK
- Model:B-62
- Material:ABS composite
- Capacity:14 cubic feet
- Maximum load:150 pounds
- Opening:Dual-side
- Crossbar compatibility:Round, square, and aerodynamic crossbars
- Mounting-hole distance:17.32–38.58 inches
- Warranty:30 days
Our verdict“Choose the VISRACK if two-sided access and a hard shell matter more than fitting tall cargo or avoiding a crossbar-spacing check.”
DNA Motoring Rooftop Cargo Box Carrier, Lockable Heavy-Duty Car Top Storage Case, 110 lbs Capacity, 53″ L x 34″ W x 15″ H, Glossy Black (PT-ZTL-8166-GSBK)
The DNA Motoring carrier is the more compact hard-shell option here: its 11-cubic-foot interior is smaller than the VISRACK’s 14 cubic feet, but the 53-by-34-by-15-inch dimensions give buyers a clearer sense of its roof footprint. That makes it a candidate for drivers who need weather-resistant storage for bags and everyday travel gear without stepping up to a larger box. Its lockable side-opening latch adds basic security while keeping access straightforward.
Its limits are just as relevant. The 110-pound capacity is lower than the VISRACK’s 150 pounds, and the carrier requires existing crossbars; universal fit does not mean it attaches to a bare roof or every rack system. I’d favor it over a soft bag when a rigid shell is the priority, but pick the Asinking bag for greater stated volume or rack-free installation.
Pros:- Rigid ABS shell offers protection from weather and impacts.
- Compact 53-by-34-by-15-inch dimensions make its physical footprint easy to compare with roof space.
- Lockable side-opening latch provides a way to secure the enclosed cargo.
- 110-pound capacity suits many ordinary luggage loads.
Cons:- Requires crossbars and may not fit every roof-rack system.
- 11-cubic-foot capacity is less than the VISRACK’s 14 cubic feet and Asinking’s 21 cubic feet.
- 110-pound maximum load is lower than the VISRACK’s stated 150-pound limit.
Best for: Drivers with crossbars who want a smaller hard-shell carrier for luggage and need a lockable enclosure.
Not ideal for: People without crossbars, those carrying heavy loads above 110 pounds, or travelers who need more than 11 cubic feet of space.
- Internal volume:11 cubic feet
- Maximum capacity:110 pounds
- Dimensions:53 × 34 × 15 inches
- Material:ABS plastic
- Fit type:Universal; crossbars only
- Opening:Side opening
- Locking system:Key lock with side-opening latch
- Water resistance:Water resistant
- Color:Glossy black
Our verdict“Pick this box if you have compatible crossbars and prefer a compact lockable hard shell over higher capacity or rack-free mounting.”
Asinking 21 Cubic Feet Waterproof Car Rooftop Cargo Carrier Bag
For buyers who need maximum stated volume and do not have roof crossbars, the Asinking bag fills a different role from the VISRACK and DNA Motoring hard-shell boxes. It offers 21 cubic feet in a flexible 840D PVC body and can be fitted with or without roof racks using the included anti-slip mat, adjustable straps, and padded door hooks. That flexibility can suit occasional trips or vehicles whose roof setup rules out a conventional box.
The softer construction is the main compromise: unlike either hard-shell option, it depends on careful closure and installation to keep water out, particularly in heavy rain. Its 4.24-kilogram weight and large 52-by-40-by-18-inch dimensions also call for handling and fit checks before loading. I’d choose it for capacity and mounting flexibility, but favor a rigid box for a more structured enclosure or frequent access.
Pros:- 21-cubic-foot capacity exceeds the stated volume of both hard-shell boxes in this batch.
- Can be installed on vehicles with or without roof racks.
- 840D PVC with triple-reinforced welded seams is designed for abrasion resistance and waterproofing.
- Includes an anti-slip mat, padded door hooks, extra straps, storage bag, and luggage lock.
Cons:- Soft construction requires careful fitting and closure to reduce leakage risk in heavy downpours.
- At 4.24 kilograms, it may be cumbersome to position and handle.
- Flexible bag shape offers less structured access than the VISRACK and DNA Motoring hard-shell boxes.
Best for: Families or occasional road-trippers who need 21 cubic feet of flexible rooftop storage and may not have crossbars.
Not ideal for: Drivers who want rigid, quick-access storage or who are unwilling to carefully secure straps and zipper flaps before wet-weather travel.
- Capacity:21 cubic feet
- Material:840D PVC
- Dimensions:52 × 40 × 18 inches
- Weight:4.24 kg
- Water resistance:Waterproof
- Fit type:Universal
- Mounting:Rooftop; with or without roof racks
- Closure:Zipper
- Color:Black
Our verdict“Choose the Asinking bag when capacity and rack-free mounting outweigh the convenience and rigid protection of a hard-shell box.”
How We Picked
I compared the 13 options by the factors that shape day-to-day usefulness: stated capacity, opening direction, hard-shell versus soft-bag construction, security features where specified, and the fit information available in each product listing. I also considered how much flexibility a carrier offers across different trips, and whether its format is likely to suit someone who needs a rigid enclosure or prefers a bag that can be stored more compactly.
The ranking gives the strongest positions to products with a clear use case and a practical balance of capacity, access, and stated features. That puts the Thule Pulse 2 L first as a balanced hard-shell choice, with the Force 3 XL in the premium position and the large soft bags serving buyers prioritizing volume and flexibility. Models with less stated detail or a narrower access or capacity profile rank lower—not because they cannot work, but because buyers have less information for comparing fit and use. I would confirm vehicle, crossbar, load, and clearance compatibility before choosing any roof-mounted carrier.

Factors to Consider When Choosing Roofcargo Boxes
Choosing a roof carrier is about more than picking the largest capacity number. I would start with the vehicle and the trips you take, then decide which compromises—access, storage, security, or roof space—you can live with.
Match the carrier to your roof and crossbars
Before comparing box sizes, check your vehicle’s roof load limit and the crossbar maker’s limits, including the weight of the carrier itself. A box’s stated cargo capacity is not permission to exceed the vehicle’s total roof allowance. Check crossbar spacing, mounting compatibility, and whether the carrier can sit in a position that leaves the hatch or rear door usable. A long box can interfere with hatch clearance even when the mounting hardware fits. Buyers often overlook this until the carrier is installed, so measure the roof and access points before ordering. If fit details are unclear, get confirmation for your exact vehicle and bar setup.
Choose hard shell or soft bag based on your routine
A hard shell keeps a fixed shape and is generally the more structured choice for repeated trips and gear that benefits from a firm enclosure. Soft bags can be easier to store when not in use and may suit occasional hauling or awkward, compressible loads. Their flexible format also makes correct installation and closure especially important; follow the maker’s instructions and check that the bag is secured as directed. Do not assume that a waterproof label means every seam and closure will protect cargo in every weather condition. For valuables or frequent unattended stops, look closely at the actual locking and security features rather than treating all carriers as equally secure. The best format depends on use and storage habits, not capacity alone.
Treat capacity as a packing guide, not a fit guarantee
Cubic feet describe volume, but they do not show whether your specific items will fit through the opening or lie flat inside. Bulky sleeping bags and coats pack differently from skis, strollers, or long cases, so compare interior dimensions and opening size when those are provided. The 21-cubic-foot soft bags in this roundup offer large stated volume, while smaller boxes may be easier to position and load on some vehicles. Overfilling can strain closures or make safe loading harder, even if cargo appears to fit. Make a short list of the largest items you plan to carry and check their length, width, and height against the carrier’s usable space. Leave room for secure closure rather than planning around a completely full volume figure.
Think through how you will load and unload
Opening direction matters most when the vehicle is parked close to a wall, another car, or a curb. Dual-side access, found on several boxes here, can make it easier to reach gear from whichever side is available. The SportRack Vista XL’s rear-opening layout serves a different access pattern and may be useful when side access is awkward, but buyers should check rear hatch clearance. Consider how tall the vehicle is and whether you can safely reach the carrier without standing on an unstable surface. A large box can be harder to load than its volume suggests when cargo must be lifted overhead. Match the opening style to your usual parking and loading routine.
Balance capacity against driving and clearance needs
A larger carrier can hold more, but it also adds bulk above the vehicle and may affect clearance in garages, parking structures, and low branches. Check the full vehicle height with the carrier mounted and loaded, then keep that figure accessible while traveling. Roof loads can also influence how a vehicle feels on the road, so follow the vehicle and carrier instructions for weight limits and secure mounting. Avoid choosing a box solely because it has the biggest capacity figure; a smaller model can be easier to live with if it covers your regular cargo. If you only need extra room for a few trips, a flexible bag may be more convenient to store, while frequent use may favor a rigid box. Your travel pattern should guide how much capacity you buy.
Check the details that affect ownership after the trip
Think about where the carrier will live when it is off the car, how often you will install it, and whether you need a lockable enclosure. A rigid box takes up more storage space than a bag, while a soft carrier may require careful drying and folding according to its care instructions. Before buying, verify what mounting hardware is included and whether it matches your crossbars; do not assume every roof system uses the same attachment method. Review the maker’s instructions for loading, closure, cleaning, and storage so you can keep the carrier in good condition. If you plan to leave gear on the roof between stops, prioritize the listed security features and avoid relying on an unspecified lock. These practical details can matter more over a season than a small difference in capacity.
Frequently Asked Questions
Should I choose a hard-shell roof box or a soft cargo bag?
I would choose a hard shell if you want a structured enclosure for repeated use and prefer a rigid box that keeps its shape. A soft bag may fit occasional trips better if compact storage when it is off the vehicle matters to you. The 21-cubic-foot FIVKLEMNZ and Asinking bags offer substantial stated volume, but a bag is not interchangeable with a lockable hard box. Check the exact closure, attachment, and care instructions for any soft carrier, particularly if you expect wet weather. Your storage space, security needs, and frequency of use should decide the format.
Will any of these roof cargo boxes fit my car’s crossbars?
Not necessarily; compatibility depends on your vehicle’s roof and the crossbar dimensions and spacing, as well as the carrier’s mounting system. Check the carrier’s fit guidance against your exact vehicle and bar setup before purchasing. Also confirm the vehicle’s roof load limit, counting the carrier’s weight and the cargo together. A box that attaches to the bars may still sit too far forward or backward for the hatch to open. If the product details do not answer your fit question, seek confirmation from the manufacturer or seller rather than guessing.
Is a 21-cubic-foot carrier always better than a 14- or 16-cubic-foot box?
No. A larger capacity can help with bulky gear, but it does not guarantee that long or oddly shaped items will fit through the opening. The larger soft bags in this roundup offer more stated volume, while the Thule Pulse 2 M and L provide smaller, defined capacities in a hard-shell format. More volume may also mean a larger footprint on the roof, so check vehicle fit, hatch clearance, and total roof load. Choose the carrier that fits the items you actually take, not the biggest number on the listing.
Which opening style is better: dual-side or rear-opening?
Dual-side opening gives you a choice of which side to load from, which can help in tight parking or when one side of the vehicle is blocked. A rear-opening design, such as the SportRack Vista XL, can suit a setup where access from behind works better. Neither style is universally easier: a rear hatch may obstruct a rear-opening box, and a wall may block one or both sides of a side-opening model. Think about your usual parking spaces and measure the clearance around the roof. The access style should fit your routine as well as your cargo.
What should I check before driving with a roof cargo carrier?
Confirm that the carrier is mounted and closed according to its instructions, and that the cargo is secured without exceeding the vehicle or carrier limits. Check the added vehicle height for garages, car parks, and low-clearance routes. Recheck mounting points and closures at the intervals recommended by the maker, especially after loading or a long drive. Keep heavy items within the carrier’s stated guidance and avoid packing in a way that strains the lid or bag closure. If anything shifts, loosens, or no longer closes properly, stop safely and correct it before continuing.
Conclusion
For the broadest mix of capacity and access, I recommend the Thule Pulse 2 L as best overall; choose the Thule Pulse 2 M if you want the same dual-side format in a smaller stated volume. The GarveeTech 12-cubic-foot box is a straightforward value-minded option for buyers who can work with less capacity, while the Thule Force 3 XL is my best premium pick for shoppers focused on a larger Thule hard-shell option. For beginners, I’d start by comparing the Pulse 2 M and L against vehicle fit and typical cargo rather than buying the largest carrier. If your priority is bulky loads and easier off-car storage, look at the FIVKLEMNZ 21-cubic-foot bag; if side access is limited, consider the SportRack Vista XL and confirm rear clearance. Whichever you choose, verify roof limits, crossbar compatibility, and full vehicle height before setting out.
