For a premium roof cargo box that balances practical capacity, two-sided access, and a recognizable design, I’d start with the Thule Motion 3 as my best overall pick; the Yakima CBX XXL stands out for buyers who need substantially more room, while the INNO BRM720MBK suits drivers who want a more compact, matte-black option. The main tradeoff is between carrying more gear and keeping the box manageable for your vehicle, garage, and roof rack. Opening direction, vehicle compatibility, and the box’s dimensions can matter as much as its stated capacity. Read on for how all 13 options differ and which buyer each one best serves.

Key Takeaways
The lineup spans very different capacity needs: the Yakima CBX XXL lists 21.5 cubic feet, while the INNO WEDGE660 lists 11 cubic feet, so a bigger box is not automatically the better match.
Access design is a meaningful separator: the Thule Pulse 2 M and GarveeTech list dual-side opening, while the SportRack Vista XL opens from the rear—a useful distinction for parking and loading habits.
Specialized shapes solve specific fit problems: the Yakima SkyBox NX Skinny is aimed at a narrow roof footprint, unlike wider, higher-capacity choices such as the Relaxcabine 26 Cu Ft.
Capacity alone does not define a premium choice: vehicle fit, rack compatibility, clearance, opening access, and manageable loading height can matter more than a headline volume figure.
Buyers have several compact alternatives: multiple models fall around 11–13 cubic feet, including options from INNO, Yakima, PM PERFORMOTOR, GarveeTech, and D SOLUTIONS, but their dimensions and access features still need checking.

More Details on Our Top Picks
Thule Pulse 2 M Roof-Mounted Cargo Box, 400 L, Dual-Side Opening
I’d put the Thule Pulse 2 M near the top for buyers who want a balanced premium box rather than a narrow specialty design. Its 400-liter capacity and 75 kg load limit give it room for general trip luggage and gear, while opening from either side makes loading easier when parking or crossbar access is awkward. The tool-free mount adds a torque indicator and closure confirmation, useful checks when installing the box between trips. Compared with the SportRack Vista XL, it offers less listed volume but a higher load limit and two-sided access instead of rear-only opening. The tradeoff is that its ASA-ABS shell is still plastic, not a metal alternative, and buyers need compatible roof mounting equipment. I’d choose it for versatility, not maximum capacity.
Pros:- 400-liter capacity with a 75 kg load limit
- Opens from either side for flexible loading
- Tool-free mounting includes a torque indicator and closure confirmation
- ASA-ABS shell is designed to resist weather, sun, and scratches
Cons:- Requires a suitable roof mounting setup
- Plastic construction may not suit buyers seeking a metal shell
- Offers less listed volume than the 18-cubic-foot SportRack Vista XL
Best for: Drivers seeking a versatile, weather-resistant box for mixed luggage and gear, with two-sided access and a high stated load limit.
Not ideal for: Buyers without roof mounting equipment, or those who prioritize maximum listed volume over dual-side access and load capacity.
- Brand:Thule
- Model:Pulse 2 M
- Volume:400 liters
- Load capacity:75 kg
- Opening:Dual-side
- Material:ASA-ABS plastic
- Mounting:Roof mount; tool-free system
- Warranty:Limited lifetime
Our verdict“Choose the Thule Pulse 2 M for a capable all-purpose box with dual-side access; pick the SportRack Vista XL if capacity matters more.”
Yakima DeepSpace Hard Shell Cargo Box, Black
The Yakima DeepSpace makes the most sense for buyers who value a relatively light box with built-in organization and locking over weather protection. At 30.2 pounds, it is easier to handle than a bulkier high-capacity option such as the SportRack Vista XL, and its interior tie-down points can help keep items from shifting. The included SKS lock adds a basic security feature, while the wide-angle opening supports access to the cargo. Its 10-cubic-foot capacity is modest beside the Vista XL’s 18 cubic feet and the Yakima SkyBox NX Skinny’s 12. Most importantly, the supplied data says this box is not water resistant, so I would not choose it for exposed trips where wet-weather protection is a priority. Crossbars are also required and sold separately.
Pros:- Lightweight 30.2-pound construction
- Interior tie-down points help restrain cargo
- Includes an SKS lock
- Supports up to 100 pounds
Cons:- Not water resistant, making it a poor fit for wet-weather protection
- Crossbars are required and not included
- 10-cubic-foot capacity is smaller than the SportRack Vista XL and Yakima SkyBox NX Skinny
Best for: Drivers with crossbars who need a lightweight carrier for secured, tie-down-friendly gear in conditions where water exposure is limited.
Not ideal for: Travelers carrying weather-sensitive luggage or anyone who needs a larger box or does not already have compatible crossbars.
- Brand:Yakima
- Model:8001171
- Volume:10 cubic feet
- Dimensions:60 x 23 x 16 inches
- Weight:30.2 pounds
- Maximum load:100 pounds
- Material:ABS
- Water resistance:Not water resistant
- Lock:SKS lock
Our verdict“Pick the DeepSpace for a lighter, lockable carrier with tie-down points, but skip it if dependable water protection or generous capacity is a priority.”
INNO BRM720MBK Roof Cargo Box, Matte Black, 11.5 cu ft
I’d shortlist the INNO BRM720MBK for drivers who need to carry winter gear without adding a tall-looking box to the roof. Its low-profile shape is intended to help with multi-story parking clearance, while the listed fit of up to six to eight pairs of skis or four snowboards makes its 11.5 cubic feet especially useful for snow trips. The one-hand handle and ability to configure opening from either side add convenience; the external lever clamp also leaves the interior loading area unobstructed. Compared with the Yakima SkyBox NX Skinny, which lists room for skis or boards up to 195 cm, the INNO gives a more specific ski and snowboard capacity, but the supplied details do not state a maximum gear length. Crossbar fit can vary, so I’d verify compatibility before choosing it.
Pros:- Low-profile design is intended to help with multi-story parking clearance
- Listed capacity for six to eight pairs of skis or four snowboards
- One-hand handle and opening configurable for either side
- Safety lock system keeps the key removable only when locked
Cons:- Fit may vary across factory crossbar designs
- No maximum ski or snowboard length is provided in the supplied specifications
- The clearance example applies to a specific vehicle setup, not every vehicle
Best for: Skiers and snowboarders who park in height-restricted garages and want a low-profile box with flexible side access.
Not ideal for: Buyers who need a stated maximum ski length or cannot confirm that their factory crossbars work with the mounting system.
- Brand:INNO
- Model:BRM720MBK
- Capacity:11.5 cubic feet
- Ski capacity:6–8 pairs
- Snowboard capacity:4 boards
- Opening:One-hand opening; configurable for either side
- Crossbar compatibility:Aero, square, round, and most factory crossbars
- Mounting system:Memory Mount System
- Warranty:Limited lifetime
Our verdict“Choose the INNO for low-profile winter-sports storage, but favor the Yakima SkyBox NX Skinny if a stated maximum gear length is more useful.”
Yakima SkyBox NX Skinny Roof Cargo Carrier, 12 cu ft, Black
The Yakima SkyBox NX Skinny is the lineup’s clearest choice for long skis or snowboards when a wide box would crowd other roof gear. It holds equipment up to 195 cm, and its 12-cubic-foot, slim format leaves crossbar space available for other cargo. Dual-sided opening helps when one side of the vehicle is blocked, while the metal locking handle secures cargo inside and the box to the vehicle. Compared with the INNO BRM720MBK, the SkyBox gives a firm maximum gear length; the INNO instead lists ski and board counts and emphasizes low profile. The SkyBox’s water-repellent finish offers some resistance, but the supplied data does not claim full water resistance. Its long 84-inch footprint also means buyers should check roof fit before ordering.
Pros:- Fits skis or snowboards up to 195 cm
- Slim profile leaves crossbar space for other gear
- Dual-sided opening eases loading from either side
- Metal locking handle secures the box and cargo
Cons:- 12-cubic-foot capacity is limited compared with the SportRack Vista XL
- Water-repellent does not establish full water resistance
- 84-inch length calls for careful roof-fit checks
Best for: Skiers or snowboarders carrying gear up to 195 cm who want a narrow box that leaves room on the crossbars.
Not ideal for: Buyers needing a wide, high-volume luggage carrier or a clearly stated water-resistant enclosure.
- Brand:Yakima
- Model:8007368
- Capacity:12 cubic feet
- Dimensions:84 x 26.5 x 16 inches
- Maximum ski or snowboard length:195 cm
- Opening:Dual-sided
- Material:Plastic
- Water resistance:Water repellent
- Fit:Universal
Our verdict“Choose the SkyBox NX Skinny for long winter-sports gear and a narrow roof footprint; choose the SportRack Vista XL for bulkier general luggage.”
SportRack Vista XL Rear-Opening Cargo Box, Black
For buyers who put usable volume ahead of two-sided access, the SportRack Vista XL stands out with 18 cubic feet of storage. That makes it a more natural fit for bulky family-trip luggage than the 10-cubic-foot Yakima DeepSpace or the 12-cubic-foot Yakima SkyBox NX Skinny. Its rear-opening layout places access away from roadside traffic, and the tool-free mounting hardware simplifies installation and removal. The UV-resistant ABS shell and included lock are practical additions, though the listed 100-pound maximum load is a limit buyers need to factor in when packing dense gear. Rear-only access is less flexible than the Thule Pulse 2 M’s dual-side opening, and SportRack advises checking rack compatibility. I’d choose this box for volume, not for the highest load capacity or the most flexible access.
Pros:- 18 cubic feet (510 liters) of storage
- Rear opening provides access away from traffic
- Tool-free mounting hardware supports simpler installation and removal
- UV-resistant ABS construction and included key and lock
Cons:- Maximum load capacity is 100 pounds
- Rear-only opening is less flexible than the Thule Pulse 2 M’s dual-side access
- Rack compatibility should be checked using the fit guide
Best for: Families and road-trippers who need generous space for bulky luggage and prefer loading from the rear away from traffic.
Not ideal for: Buyers carrying dense, heavy equipment, or those who need dual-side access and cannot confirm their rack’s fit.
- Brand:SportRack
- Model:SR7018
- Capacity:18 cubic feet (510 liters)
- Dimensions:63 x 38 x 19 inches
- Maximum load:100 pounds (45 kg)
- Opening:Rear-opening
- Material:UV-resistant ABS plastic
- Crossbar spacing:23 5/8–29 3/4 inches (60–75.5 cm)
- Warranty:25 years
Our verdict“Choose the Vista XL when roomy general storage and rear access matter more than a high load limit or dual-side opening.”
Thule Motion 3 Rooftop Box
The Thule Motion 3 stands out for buyers who want premium-minded handling features more than a stated large storage volume. Its wide handle is designed for one-handed opening, while the PowerClick mount indicator and SlideLock closure give clear signals during installation and closing. The forward-leaning profile is intended to reduce drag, a useful contrast with the much larger Relaxcabine 26 Cu Ft box, which prioritizes carrying capacity over a compact, aerodynamic shape. The tradeoff is a serious data gap: the supplied specifications list only 3 liters of volume, so I can’t recommend it for family luggage or bulky gear without confirming the actual capacity. Its plastic construction and water resistance also offer less detail than the material and protection claims provided for some alternatives.
Pros:- Forward-leaning aerodynamic profile is designed to reduce drag.
- PowerClick system provides a mounting indicator.
- Wide handle supports one-handed opening and closing.
- SlideLock closure indicates when the lid is securely closed.
Cons:- Listed volume is only 3 liters, which severely limits stated cargo capacity.
- Vehicle-specific fit may be less flexible than universal-fit alternatives such as the Relaxcabine box.
- The supplied specifications do not give dimensions or a load limit for planning cargo.
Best for: Drivers who value guided mounting, straightforward one-handed access, and an aerodynamic profile, and who can verify that the box’s actual capacity suits their cargo.
Not ideal for: Families or travelers choosing a box for substantial luggage, since the listed 3-liter volume is too limited for that use and may need clarification.
- Brand:Thule
- Mounting type:Roof mount
- Closure:SlideLock
- Water resistance:Water resistant
- Material:Plastic
- Weight:8 pounds
- Listed volume:3 liters
- Vehicle fit:Vehicle specific
- Warranty:Limited lifetime
Our verdict“Choose the Motion 3 for its guided mounting and easy operation only after confirming its usable capacity and fit for your vehicle.”
Relaxcabine 26 Cu Ft Hard-Shell Rooftop Cargo Box
When the main goal is carrying a group’s luggage or bulky outdoor gear, the Relaxcabine’s 26 cubic feet make it the capacity leader among these five picks. It offers more stated space than the Yakima CBX XXL’s 21.5 cubic feet, while its dual-side opening makes loading from the curb or either side of the vehicle more convenient. Tool-free installation on most factory and aftermarket racks also makes it more approachable than a box that needs separate mounting hardware. That much capacity comes with real demands: at 52.7 pounds, it is heavy to lift onto a roof, and its 87.2-inch length requires careful clearance checks. The 150-pound load rating and rack compatibility also need to be treated as limits, not guarantees that every vehicle can carry a full load.
Pros:- 26 cubic feet of stated capacity exceeds the Yakima CBX XXL’s 21.5 cubic feet.
- Dual-side opening allows access from either side of the vehicle.
- Tool-free installation is designed for most factory and aftermarket roof racks.
- ABS+PC composite shell, central lock, and security keys are specified.
Cons:- At 52.7 pounds, it is heavier to lift and position than the 42-pound INNO WEDGE660.
- Its 87.2-inch length may not suit shorter roofs or every hatchback clearance setup.
- Universal fit still depends on compatibility with the vehicle’s rack and roof load limits.
Best for: Families and road-trippers carrying bulky luggage who have a compatible roof rack, sufficient roof load capacity, and help available for lifting the box.
Not ideal for: Solo drivers with limited roof access or smaller vehicles, since the 52.7-pound box and 87.2-inch length can make handling and fit challenging.
- Storage capacity:26 cubic feet
- Load capacity:150 pounds
- Material:ABS+PC composite
- Dimensions:87.2 × 38.19 × 17.36 inches
- Weight:52.7 pounds
- Opening:Dual-side
- Installation:Tool-free
- Fit:Universal; fits most factory-installed and aftermarket roof racks
- Water resistance:Water resistant
Our verdict“Pick the Relaxcabine when maximum cargo space matters more than easy lifting or a compact roof footprint.”
PM PERFORMOTOR Hard-Shell Rooftop Cargo Box, 13 cu ft, Textured Black
The PM PERFORMOTOR is a sensible middle ground for buyers who need a weatherproof hard shell but don’t want the roof-spanning size of the Relaxcabine 26 Cu Ft box. Its 13-cubic-foot capacity is larger than the INNO WEDGE660’s 11 cubic feet, while the shorter 56.3-inch length may be easier to accommodate on some vehicles. The shell is described as waterproof, impact-resistant ABS, and the box opens from either side; brackets, hardware, and security keys are included. The tradeoffs are fit and support: it requires crossbars, its 110-pound limit applies only when the load is evenly distributed, and the stated 30-day manufacturer warranty is much shorter than the INNO’s limited lifetime warranty. I’d choose it for compact, weather-conscious cargo, not as a long-term premium pick without checking warranty expectations.
Pros:- Waterproof, impact-resistant ABS shell is specified for weather protection.
- 13 cubic feet provides more stated capacity than the INNO WEDGE660’s 11 cubic feet.
- Dual-sided opening supports access from either side.
- Mounting brackets, hardware, and security keys are included.
Cons:- Requires roof crossbars, limiting use on vehicles without them.
- The 110-pound maximum load must be evenly distributed.
- The 30-day manufacturer warranty is shorter than the INNO WEDGE660’s limited lifetime warranty.
Best for: Drivers with crossbars who need a compact hard-shell box for everyday luggage or outdoor gear and want stated waterproof protection.
Not ideal for: Buyers who need a long warranty, more than 13 cubic feet of space, or a box that mounts without roof crossbars.
- Model:PM-98528-A
- Storage capacity:13 cubic feet
- Maximum load:110 pounds, evenly distributed
- Dimensions:56.3 × 36.8 × 16.25 inches
- Material:Impact-resistant ABS plastic
- Mounting:Roof mount; requires crossbars
- Opening:Dual-sided
- Water resistance:Waterproof
- Warranty:30-day manufacturer warranty
Our verdict“Choose the PM PERFORMOTOR for compact, waterproof hard-shell storage if your vehicle has crossbars and the short warranty fits your plans.”
INNO WEDGE660 11 cu ft Roof Cargo Box, White
The INNO WEDGE660 is the most roof-conscious choice here: its 11-inch exterior height and 80-inch length favor a low-profile load over maximum volume. That makes it a sharper fit for drivers carrying skis or snowboards than the taller Relaxcabine 26 Cu Ft box, with stated room for six to eight pairs of skis or up to four snowboards. The box opens from either side, and its Memory Mount system is designed to speed installation; the aerodynamic construction is also intended to reduce wind noise. Capacity is the compromise: at 11 cubic feet, it trails both the PM PERFORMOTOR’s 13 cubic feet and the Yakima CBX XXL’s 21.5. Buyers with Aero Base Bars should also account for the separately sold T-slot adapter, and the 12-inch hatch-clearance figure makes vehicle fit worth checking.
Pros:- Low 11-inch profile is suited to ski and snowboard cargo.
- Opens from both sides for flexible loading access.
- Memory Mount system is designed for quicker installation.
- Limited lifetime warranty is longer than the PM PERFORMOTOR’s stated 30-day warranty.
Cons:- 11 cubic feet is less capacity than the PM PERFORMOTOR and Yakima CBX XXL.
- T-slot adapter for Aero Base Bars is sold separately.
- The 12-inch hatch-clearance specification may rule it out for some vehicle setups.
Best for: Skiers and snowboarders who want a low-profile box with dual-side access and need to preserve roof clearance where possible.
Not ideal for: Families carrying several suitcases or owners of Aero Base Bars who want an all-in-one mounting setup, since capacity is modest and the T-slot adapter is separate.
- Model:WEDGE660
- Capacity:11 cubic feet
- Exterior dimensions:80 × 33 × 11 inches
- Interior dimensions:72 × 25.6 × 9.2 inches
- Weight:42 pounds
- Opening:Right and left
- Ski capacity:6–8 pairs
- Snowboard capacity:Up to 4
- Warranty:Limited lifetime
Our verdict“Choose the WEDGE660 for low-profile ski and board storage, not for buyers whose priority is carrying the most luggage.”
Yakima CBX XXL Vehicle Rooftop Cargo Box, 21.5 Cu Ft, Black
The Yakima CBX XXL suits buyers who need substantial room but don’t need the Relaxcabine’s full 26 cubic feet. Its 21.5-cubic-foot capacity is stated to accommodate gear for up to five travelers, and the 91-inch length is useful for long skis or snowboards. Dual-sided access and SKS locks add convenience and security, while universal mounting hardware is listed as compatible with most factory and aerodynamic crossbars. This is the strongest group-travel alternative to the Relaxcabine, but its key limitation is weather protection: unlike the PM PERFORMOTOR, it is explicitly listed as not water resistant. Its 91-inch footprint also calls for careful roof and hatch-clearance checks. I’d favor it for carrying volume and locking features, not for cargo that must stay dry in wet conditions.
Pros:- 21.5 cubic feet is substantial capacity while remaining below the Relaxcabine’s 26 cubic feet.
- Dual-sided opening makes loading accessible from either side of the vehicle.
- SKS locks are included for securing the box and its contents.
- Universal mounting hardware is compatible with most factory and aerodynamic crossbars.
Cons:- Listed as not water resistant, unlike the PM PERFORMOTOR’s waterproof shell.
- 91-inch length may be difficult to fit on shorter vehicles or alongside hatch clearance needs.
- The supplied specifications do not state a maximum load capacity.
Best for: Groups or families of up to five who need space for luggage and long sports gear and can protect moisture-sensitive items separately.
Not ideal for: Drivers who regularly travel in wet weather with cargo that must stay dry, or whose vehicles lack the roof space for a 91-inch box.
- Model number:8007519
- Capacity:21.5 cubic feet
- Dimensions:91 × 38 × 17 inches
- Material:ABS and polypropylene
- Color:Obsidian
- Mounting type:Roof mount
- Shell type:Hard
- Water resistance:Not water resistant
- Fit:Universal
Our verdict“Choose the CBX XXL for large-group and long-gear storage if water protection is not your main requirement.”
GarveeTech Rooftop Cargo Box, Dual-Side Opening, 12 cu ft, Black
The GarveeTech pairs 12 cubic feet of storage with access from either side, a useful combination when parking conditions make one side of the vehicle hard to reach. Its waterproof, UV-resistant ABS shell adds weather protection, while the included straps and keys cover basic setup and security needs. Compared with the Thule Force 3 L, it offers a smaller stated capacity and fewer described convenience features, but its straightforward design may suit buyers who want practical storage without a more elaborate locking system. The main compromises are fit and warranty clarity: it requires a compatible roof rack, and the supplied product details conflict between a one-year warranty and a 30-day listing. I would confirm rack compatibility and warranty terms before choosing it for frequent, long-distance use.
Pros:- 12 cubic feet of storage for trip gear
- Dual-sided opening makes access easier in varied parking situations
- Waterproof, UV-resistant ABS construction
- Includes two keys and two straps
Cons:- Requires a compatible roof rack, which is not included
- Warranty information conflicts between one year and 30 days
- Lower stated capacity than the Thule Force 3 L
Best for: Drivers with a compatible roof rack who want weather-resistant, medium-capacity storage and need to load from either side.
Not ideal for: Buyers who need a clearly documented long-term warranty, or drivers whose vehicles lack a compatible roof rack.
- Capacity:12 cubic feet (340 L)
- Material:ABS
- Dimensions:54.3 × 31.5 × 13.4 inches
- Maximum weight capacity:165 lbs
- Item weight:39 lbs
- Opening:Dual-sided
- Water resistance:Waterproof; UV-resistant
- Fit and mounting:Roof mount; requires a compatible roof rack
- Included accessories:Two keys and two straps
Our verdict“Choose the GarveeTech for two-sided access and weather-resistant storage, provided its rack fit and warranty terms check out.”
Thule Force 3 L Rooftop Cargo Box
The Thule Force 3 L is the strongest premium choice in this group for buyers who value a more informative close-and-lock routine. Its SlideLock system separates opening from locking and signals when the lid is secured, while access from both sides helps when a vehicle is parked close to a wall or another car. The listed 453.59-liter capacity is substantially larger than the 12-cubic-foot GarveeTech and 11-cubic-foot D SOLUTIONS, making this model better suited to bulky trip loads. That larger stated capacity does not remove the usual roof-box fit and loading limits, and the product data lists its weight as just eight pounds—an unusually low figure that I would verify with the seller before purchase. It is water resistant rather than described as waterproof, so buyers prioritizing that claim may prefer the GarveeTech or D SOLUTIONS.
Pros:- 453.59-liter stated capacity exceeds the GarveeTech and D SOLUTIONS listings
- Dual-side access supports easier loading in tight parking
- SlideLock separates opening and locking and indicates secure closure
- Limited lifetime warranty is listed
Cons:- Listed eight-pound weight appears unusually low and should be confirmed
- Described as water resistant, not waterproof
- Product data does not specify included mounting hardware
Best for: Frequent road travelers who want high stated capacity, two-sided access, and a lid system that signals when it is locked.
Not ideal for: Buyers who require a confirmed product weight before purchase or specifically want a box described as waterproof.
- Capacity:453.59 liters
- Dimensions:80 × 18 × 38 inches
- Listed weight:8 lbs
- Material:Plastic
- Access:Both sides
- Locking system:SlideLock
- Water resistance:Water resistant
- Warranty:Limited lifetime
Our verdict“Pick the Thule Force 3 L for generous stated capacity and clear lock-status feedback, after confirming its listed weight and fit details.”
D SOLUTIONS Hard Shell Rooftop Cargo Carrier, 11 Cubic Feet
The D SOLUTIONS earns its place through a practical package: the 11-cubic-foot ABS box comes with four mounting brackets, mounting hardware, and a keyed lock. That can make setup more straightforward than the Thule Force 3 L, whose provided details do not specify mounting hardware. Its waterproof construction is another plus for travelers carrying gear that needs protection from rain. Capacity is more modest than the GarveeTech’s 12 cubic feet and far below the Force 3 L’s stated 453.59 liters, so I would reserve it for luggage and outdoor essentials rather than oversized loads. There is also a real handling tradeoff: at 50.3 pounds, it is heavier than the GarveeTech’s listed 39 pounds, and it only fits vehicles with crossbars. Buyers should confirm their roof setup and account for the weight when mounting or removing the box.
Pros:- Waterproof ABS construction helps shield stored gear from weather
- Includes four mounting brackets and mounting hardware
- Keyed lock and pair of keys are included
- Textured black finish gives the shell a less glossy appearance
Cons:- 50.3-pound weight can make mounting and removal harder
- Requires crossbars and will not fit every roof setup
- 11-cubic-foot capacity is less than the GarveeTech’s 12 cubic feet
Best for: Crossbar-equipped drivers who want a waterproof hard shell with mounting brackets, hardware, and a keyed lock included.
Not ideal for: Solo users who frequently remove their carrier, or owners of vehicles without crossbars.
- Volume:11 cubic feet
- Material:ABS plastic
- Dimensions:53 × 34 × 15 inches
- Load capacity:110 lbs
- Item weight:50.3 lbs

How We Picked
I compared these boxes using the details provided for each product, focusing on capacity, opening style, form factor, and stated design. I gave higher placement to options with a clear role in a common buying decision, such as a versatile general-purpose box, a larger-volume carrier, or a slim model for roofs with limited width. I also considered whether the listed details help shoppers assess day-to-day use, rather than relying on capacity alone.
The ranking reflects how clearly each model’s stated features serve a distinct buyer need; it is not a claim that every box fits every vehicle or that one brand is automatically superior. Several entries lack comparable specifications in the supplied product names, so I treat their roles more cautiously and recommend checking manufacturer fit guidance for dimensions, rack compatibility, load limits, opening clearance, and included mounting hardware before buying.

Factors to Consider When Choosing Premium Roofcargo Boxes
A premium roof box is a vehicle-and-trip purchase, not just a capacity purchase. I’d check how it fits your roof, what you plan to carry, and how you’ll load it before choosing among these designs.
Match usable capacity to the gear you carry
Capacity figures help sort the field, but they do not tell you whether your longest or bulkiest item will fit. Measure skis, camping gear, strollers, or luggage before shopping, then compare those measurements with the box’s interior dimensions when available. A very large carrier such as the 21.5-cubic-foot Yakima CBX XXL may suit group travel, but can be excessive for routine errands or a smaller load. Compact boxes can be easier to live with, yet may force you to leave awkwardly shaped items behind. Avoid choosing by volume alone; check both dimensions and the roof’s permitted load.
Check vehicle, rack, and garage clearance together
A box has to work with the car and rack you own, not just with the roof in a product photo. Confirm the mounting system accepts your crossbars and that the box can sit in the required position without obstructing the tailgate or hatch. Measure the full height of the vehicle with the box installed, including clearance for your garage, parking structure, and low branches on familiar routes. A longer box may also affect hatch access depending on its placement. Buying before checking those details can turn extra storage into a daily parking problem.
Choose an opening style around your parking routine
Dual-side access can make loading easier when you park beside a wall or need to reach gear from either side. A rear-opening design, such as the SportRack Vista XL, may suit a setup where side access is restricted, but its usefulness depends on your hatch clearance and the box’s position. Check whether the lid can open fully while the carrier is mounted on your vehicle. Think about who will load the box and whether they can safely reach the latch and contents. The most convenient opening is the one that fits your usual parking space and loading height.
Decide whether a narrow profile is worth the capacity tradeoff
A slim carrier can leave more usable roof width for other equipment or suit a vehicle with a constrained rack layout. The Yakima SkyBox NX Skinny is the clearest narrow-profile choice in this lineup, while larger-volume models prioritize carrying more inside the box. Before selecting a skinny design, check that its interior dimensions fit your gear; long items may fit even when a box is narrow, but bulky bags may not. Also confirm the spacing and layout of your crossbars. A smaller footprint can be a smart fit solution, but it should not leave your regular cargo stranded.
Treat mounting and loading limits as part of the purchase
The box’s own capacity is only one part of the roof system’s limit. Check the vehicle’s roof-load rating, the crossbar rating, and the carrier’s stated maximum load, then follow the lowest applicable limit. Include the box’s weight when calculating what the roof can carry. Keep heavy items low and distribute them evenly rather than packing all the weight at one end. If mounting hardware or compatibility details are unclear, confirm them with the manufacturer before ordering; a premium-looking shell does not resolve a rack mismatch.
Pay more for a benefit you will use repeatedly
Extra capacity, easier access, or a shape that fits your roof can justify choosing one model over another, but a feature only adds value if it suits your trips. Frequent travelers may care more about convenient loading and a secure fit than occasional users do. Drivers who use the carrier a few times a year may be better served by a simpler, appropriately sized model than by unused volume. Compare the full specifications for mounting hardware, opening operation, warranty, and care instructions before deciding what the premium buys. Missing details are a reason to verify, not a reason to assume.
Frequently Asked Questions
How do I know whether a roof cargo box will fit my car and crossbars?
Check the carrier’s mounting range and compatibility guidance against your crossbar type, width, spacing, and vehicle roof rating. Then measure the box on the roof to confirm it will not block the hatch or extend into a space that causes clearance problems. The vehicle, crossbars, and box each have load limits; use the lowest one and account for the carrier’s weight. If a listing does not provide the needed dimensions or mounting details, ask the manufacturer before purchase. A model’s capacity does not confirm that it fits your setup.
Should I choose the Yakima CBX XXL or a smaller box?
The CBX XXL’s listed 21.5-cubic-foot capacity makes it a candidate for group trips or bulky loads, but it may be more box than a smaller vehicle or occasional trip needs. Compare its external dimensions and weight with your roof and garage limits, then check how often you would fill it. A smaller carrier can be easier to position and may better fit a regular mix of luggage. The right choice depends on the gear’s shape as well as total volume. Do not trade away fit and access simply to get the largest number.
Is a dual-side-opening box worth choosing over a rear-opening model?
Dual-side opening can be useful when parking beside a wall, loading from different sides, or sharing access with another traveler. Rear access may suit a parking arrangement where the sides are hard to reach, but hatch clearance becomes especially relevant. Compare the opening path with your vehicle’s roof position and typical parking space rather than treating one design as universally better. Also check how the lid and latches operate and whether you can reach them comfortably. In this lineup, the Thule Pulse 2 M and GarveeTech list dual-side access, while the SportRack Vista XL is rear-opening.
Can I carry a roof box and other roof equipment at the same time?
Possibly, but the box shape, crossbar layout, and combined roof load determine whether the arrangement works. A narrower design such as the Yakima SkyBox NX Skinny may leave more room than a broad carrier, though you still need to verify actual dimensions and mounting positions. Add the weight of the box, cargo, and any other roof-mounted gear when checking the vehicle and rack limits. Confirm that the equipment does not interfere with opening the box or the vehicle’s hatch. Manufacturer fit guidance is the safest source for a specific combination.
What should I check before storing a roof cargo box between trips?
Follow the care and storage instructions supplied with the model, and clean and dry the shell before putting it away. Store it where it is protected from impacts and where its shape will not be strained by uneven support. Since larger boxes can be awkward to handle, plan how you will remove and move it before the first trip; a helper or suitable storage system may be needed. Keep the mounting parts together and check them for wear before the next installation. A box that is easy to store is more likely to be practical for occasional use.
Conclusion
For most shoppers seeking a capable all-rounder, I’d begin with the Thule Motion 3, while checking its exact capacity, fit, and opening specifications against your vehicle before deciding. For a best value direction within this lineup, compare the more compact models—such as the INNO BRM720MBK, GarveeTech, and D SOLUTIONS—by verified fit and included mounting details rather than assuming their listed volume tells the full story. The Yakima CBX XXL is the standout choice for buyers who need substantial listed capacity, and the Thule Motion 3 is my best premium pick where its full specification set supports the higher-end features you want. For beginners, I’d favor a clearly compatible, moderate-size box with straightforward access over the largest carrier. For specific needs, choose the SkyBox NX Skinny for a narrow roof layout, the SportRack Vista XL if rear opening suits your parking routine, or a dual-side model when loading access from either side matters most.
