For most SUV owners, I’d start with the Thule Pulse 2 M: its 14-cubic-foot capacity and dual-side opening offer a useful balance of access and manageable size. The Yakima SkyBox NX 18 XLG is a standout for shoppers who want a larger hard-shell carrier, while the SportRack Vista XL suits drivers who prefer rear access. Soft bags from Asinking, Sailnovo, and others can pack down for storage, but they call for closer attention to roof-rack compatibility and weather protection. The main tradeoff is between a rigid box’s structure and convenience, a soft carrier’s easier storage, and the vehicle fit each demands. Read on for the full comparison and help matching a carrier to your SUV and cargo.

Key Takeaways
- The hard-shell picks are not interchangeable: the Thule Pulse 2 M pairs a 14-cubic-foot size with access from both sides, while the larger Yakima SkyBox NX 18 XLG prioritizes more enclosed capacity.
- Access direction can matter as much as volume: the SportRack Vista XL opens at the rear, a practical distinction for drivers who often load from behind the SUV.
- The roundup includes many soft bags: Sailnovo, Asinking, MIDABAO, FIVKLEMNZ, and the 15-cubic-foot carrier offer pack-away convenience, but require careful checks of mounting method, roof support, and weather exposure.
- Capacity claims alone do not settle fit: the list spans 12 to 21 cubic feet, but a box or bag still needs to match the SUV roof, crossbars, hatch clearance, and permitted roof load.
- Several entries share similar roles: the three Garvee or GarveeTech hard boxes are differentiated by capacity and listing details, so buyers should compare dimensions and mounting hardware rather than relying on brand name alone.

More Details on Our Top Picks
Sailnovo 20-Cubic-Foot Rooftop Cargo Bag
For SUV owners who want room for bulky luggage without storing a hard box year-round, the Sailnovo 20-cubic-foot bag is the flexible pick. Its fabric body folds into its storage bag, unlike the rigid SportRack Vista XL, which needs dedicated storage space when it is off the roof. The 1000D Oxford cloth, reinforced stitching, and included tie-downs suit road trips where extra cargo space matters more than a molded shell. Its broad roof compatibility can also help buyers whose SUV lacks crossbars, though no-rack installation depends on an exposed metal door-frame edge. The tradeoff is less convenience and security than a hard box: it needs careful securing, is not recommended over a sunroof without a roof basket, and its 51-by-39-inch footprint may overhang very small vehicles.
Pros:- 20 cubic feet of capacity for luggage and camping gear
- Folds into a storage bag when not in use
- Tear-resistant 1000D Oxford cloth with reinforced stitching
- Includes six tie-down straps and six safety hooks
Cons:- No-rack installation requires an exposed metal door-frame edge
- Not recommended for sunroof vehicles unless used with a roof basket
- Its large footprint may overhang very small cars
Best for: SUV owners who need high-volume, stowable cargo space and have a suitable roof setup or basket.
Not ideal for: Drivers seeking rigid, lockable storage, or owners with small roofs, sunroofs, or no exposed metal door-frame edge for rack-free installation.
- Capacity:20 cubic feet
- Dimensions:51 × 39 × 17 inches
- Material:1000D Oxford cloth
- Compatibility:Most roofs with crossbars, side rails, baskets, or no rack
- Included accessories:6 tie-down straps and 6 safety hooks
- Storage:Folds into a storage bag
Our verdict“Choose the Sailnovo if you want generous, fold-away capacity and can accommodate its installation and roof-fit limits.”
Hard Shell Rooftop Cargo Carrier
This ABS hard-shell carrier is a straightforward choice for SUV owners who already have crossbars and want a weather-resistant enclosure with a keyed lock. Unlike the Sailnovo cargo bag, it has a rigid shell and lock, making it a better fit for buyers who prefer a structured container over fabric and straps. The 53-by-34-inch footprint offers useful luggage space without relying on a soft bag’s rack-free tie-down approach. Its limits are clear: it fits only vehicles with crossbars, and the supplied brackets and hardware still need to be mounted to the roof. The listed details do not give a storage capacity or opening direction, so buyers comparing it with the 14-cubic-foot Garvee or dual-side-opening Thule should not assume equivalent room or access convenience.
Pros:- ABS plastic shell provides a rigid cargo enclosure
- Weather-resistant design helps protect luggage
- Keyed lock and two keys are included
- Four mounting brackets and mounting hardware are supplied
Cons:- Compatible only with vehicles equipped with crossbars
- Requires roof mounting and suitable crossbar fit
- Product data does not specify capacity or opening direction
Best for: SUV owners with crossbars who want a hard-shell carrier with a keyed lock and included mounting hardware.
Not ideal for: Drivers without crossbars, or buyers who need a stated capacity, dual-side access, or a rack-free cargo solution.
- Material:ABS plastic
- Load capacity:110 lbs
- Dimensions:53 × 34 × 15 inches
- Vehicle compatibility:Vehicles with crossbars
- Color/finish:Black textured surface
- Lock:Keyed lock
- Included accessories:Two keys, four mounting brackets, and mounting hardware
Our verdict“Pick this carrier if your SUV has crossbars and a lockable hard shell matters more than specified capacity or side-access features.”
Garvee Dual-Side Opening Rooftop Cargo Box, 14 Cubic Feet
The Garvee 14-cubic-foot box stands out for access: opening from either side lets SUV passengers load from the side that suits the parking spot, while the rear-opening SportRack Vista XL prioritizes access away from traffic. Its waterproof, UV-resistant ABS shell offers a rigid alternative to the foldable Sailnovo bag, and the 165-pound maximum load capacity is higher than the Vista XL’s listed 100-pound limit. The compromise is a smaller 14-cubic-foot volume than either the SportRack’s 18 cubic feet or Sailnovo’s 20. At 43 pounds, it is also a substantial box to lift onto the roof, and it requires a compatible roof rack. The supplied description gives two different warranty durations—one year and 30 days—so I would confirm the applicable coverage before buying.
Pros:- Dual-sided opening offers access from either side of the SUV
- Waterproof, UV-resistant ABS construction
- 165-pound maximum load capacity
- Includes two keys and two securing straps
Cons:- Requires a compatible roof rack
- Weighs 43 pounds, making rooftop installation more demanding
- Warranty information conflicts between one year and 30 days
Best for: SUV owners with a roof rack who value loading access from either side and want a waterproof hard shell.
Not ideal for: Buyers who need maximum cargo volume, a light box to lift alone, or unambiguous warranty terms.
- Capacity:14 cubic feet (390 L)
- Dimensions:62.2 × 31.5 × 13.4 inches
- Weight:43 pounds
- Maximum load capacity:165 pounds
- Material:ABS
- Opening:Dual-sided
- Water resistance:Waterproof
- Fit and mounting:Universal roof-mount fit; requires a roof rack
- Included accessories:2 keys and 2 straps
Our verdict“Choose the Garvee for two-sided access and a high listed load limit, provided its 14-cubic-foot capacity and lifting weight suit your needs.”
SportRack Vista XL Rear-Opening Cargo Box
With 18 cubic feet of storage and a rear-opening lid, the SportRack Vista XL suits SUV owners who want a larger hard box and prefer loading from behind the vehicle rather than standing beside traffic. It offers more stated volume than the 14-cubic-foot Garvee and Thule boxes, while its tool-free mounting hardware can simplify putting it on or taking it off compatible crossbars. The rear opening is a distinct tradeoff: unlike those dual-side-opening models, it does not give you a choice of loading side. Fit also depends on rack compatibility and crossbar spacing of 23 5/8–29 3/4 inches. Its 100-pound maximum load is lower than the Garvee’s listed 165 pounds, so I would weigh cargo as well as compare volume before choosing.
Pros:- 18 cubic feet of storage exceeds the listed capacity of the Garvee and Thule options
- Rear opening keeps loading access away from side traffic
- Tool-free mounting hardware supports easier installation and removal
- UV-resistant ABS construction with a key and lock included
Cons:- Crossbar spacing and rack compatibility can limit fit
- Maximum load capacity is 100 pounds, below the Garvee’s listed limit
- Rear-only opening provides less loading-side flexibility than dual-side boxes
Best for: SUV owners who want 18 cubic feet of hard-shell storage, rear access, and a compatible rack with the specified crossbar spacing.
Not ideal for: Drivers who need dual-side access, have crossbars outside the stated spacing range, or expect to carry more than 100 pounds.
- Capacity:18 cubic feet (510 L)
- Dimensions:63 × 38 × 19 inches
- Material:UV-resistant ABS plastic
- Opening:Rear opening
- Mounting:Crossbar mount; tool-free hardware
- Compatibility:SportRack, square, round, and most factory roof racks
- Crossbar spacing:23 5/8–29 3/4 inches (60–75.5 cm)
- Maximum load capacity:100 lb (45 kg)
- Warranty:25 years
Our verdict“Pick the Vista XL if your SUV rack fits its spacing and you value rear access and extra volume over dual-side opening or a higher load limit.”
Thule Pulse 2 M Roof-Mounted Cargo Box, 14 cu ft, Dual-Side Opening
The Thule Pulse 2 M is the fit for SUV owners who value straightforward installation and access from either side more than maximum volume. Its tool-free mounting system with a torque indicator gives a clear cue during attachment, while closure confirmation helps reduce uncertainty when securing the box. The forward position is intended to preserve trunk access and help prevent contact with the box—a practical contrast with larger boxes such as the 18-cubic-foot SportRack Vista XL, which puts capacity ahead of a compact footprint. At 14 cubic feet, this Thule has less stated storage than the Vista XL or the Sailnovo bag. Its 75 kg load capacity is generous on paper, but buyers still need to follow the vehicle and roof-rack limits; product data does not provide dimensions or crossbar fit details.
Pros:- Dual-side opening gives access from either side of the SUV
- Tool-free mounting includes a torque indicator
- Closure confirmation helps verify the box is secured
- Weather-resistant ASA-ABS construction and forward positioning support everyday usability
Cons:- 14-cubic-foot capacity is less than the SportRack Vista XL’s 18 cubic feet
- Requires a suitable roof mounting setup
- Product data does not list dimensions or crossbar spacing
Best for: SUV owners who want a 14-cubic-foot hard box with dual-side access, guided tool-free mounting, and trunk clearance.
Not ideal for: Buyers who prioritize maximum volume, need stated dimensions or fit measurements before purchase, or want a rack-free carrier.
- Type:Roof-mounted cargo box
- Capacity:400 litres (14 cubic feet)
- Load capacity:75 kg
- Opening:Dual-side
- Mounting:Tool-free system with torque indicator
- Material:ASA-ABS plastic
- Positioning:Forward position supports trunk access and helps reduce contact with the box
Our verdict“Choose the Thule Pulse 2 M if mounting guidance and two-sided access matter more than the larger capacity of the SportRack Vista XL.”
Asinking 21-Cubic-Foot Waterproof Rooftop Cargo Carrier Bag
For SUV owners who want to move bulky trip gear without choosing a rigid box, this Asinking bag offers the largest stated capacity in this group at 21 cubic feet. Its 840D PVC fabric, reinforced seams, and zipper cover with wide hook-and-loop flaps are designed to limit water entry, while the included mat and padded door hooks give rack-free vehicles a mounting option. Compared with the 20-cubic-foot Asinking model, it adds a little stated capacity but does not provide the same clear dimensions or an IPX66 rating, so buyers have less detail for checking roof fit and water protection. The tradeoff is the usual soft-bag routine: straps and hooks need careful tightening, and the fabric does not give gear the structure or security of the Yakima SkyBox NX 18 XLG.
Pros:- 21-cubic-foot capacity suits bulky family-trip luggage.
- Reinforced seams and a covered waterproof zipper add weather protection.
- Can be secured to vehicles with or without roof racks.
- Includes an anti-slip mat, padded door hooks, extra straps, and a storage bag.
Cons:- Straps and door hooks require careful setup and tensioning.
- Exact dimensions are not provided, making roof-fit checks harder.
- Soft construction offers less structure and security than a hard-shell box.
Best for: SUV owners carrying bulky, soft-sided luggage who need a large carrier and may not have roof crossbars.
Not ideal for: Drivers who want quick hard-shell access, strong theft deterrence, or exact dimensions to confirm clearance before buying.
- Capacity:21 cubic feet
- Material:840D PVC fabric
- Water protection:Waterproof zipper cover with 6-inch hook-and-loop flaps and reinforced seams
- Vehicle compatibility:Vehicles with or without roof racks
- Included accessories:Anti-slip mat, 6 padded door hooks, 2 extra luggage straps, storage bag, luggage lock
- Construction:Soft-sided rooftop cargo bag
Our verdict“Choose this Asinking bag if you want the roundup’s largest stated soft-carrier capacity and can manage a hands-on tie-down setup.”
Asinking Car Rooftop Cargo Carrier Bag, 100% Waterproof Non-Rip 20 Cubic Feet Car Roof Bag for All Vehicles with/without Rack
This is the more clearly specified weather-minded choice among the soft carriers here: its IPX66 rating, double-coated 900D PVC tarpaulin, and three-sided watertight zipper give buyers concrete protection details, rather than relying only on broad waterproof claims. At 20 cubic feet, it has slightly less stated room than the 21-cubic-foot Asinking bag, but its listed 40-by-52-inch footprint makes roof-fit planning easier. It also works with or without a rack and includes a non-slip mat and door hooks. Compared with the hard-shell Yakima SkyBox NX 18 XLG, this bag is lighter to store and more flexible in its mounting options, but it cannot match the box’s rigid structure or lockable shell. Careful strap tension matters: a loosely secured soft carrier can flap at highway speeds.
Pros:- IPX66 rating and three-sided watertight zipper provide specific weather-protection details.
- 900D double-coated PVC tarpaulin is abrasion-resistant.
- Fits vehicles with or without roof racks.
- Includes a non-slip mat, anti-scratch door hooks, combination lock, and storage bag.
Cons:- Soft-sided construction offers less structure and security than a hard-shell box.
- Straps must be tightened carefully to limit movement and flapping at speed.
- Its 40-by-52-inch footprint may be too large for some small vehicles.
Best for: SUV drivers who want a soft carrier for wet-weather trips and value a stated water-resistance rating and listed dimensions.
Not ideal for: Buyers seeking rigid cargo protection, hard-shell theft resistance, or a compact carrier for a very small vehicle.
- Capacity:20 cubic feet
- Dimensions:40 L × 52 W inches
- Material:900D double-coated abrasion-resistant PVC laminated tarpaulin
- Water protection:IPX66 rating and three-sided watertight zipper
- Vehicle compatibility:Vehicles with or without roof racks
- Included components:Combination lock, non-slip mat, storage bag, 4 anti-scratch door hooks
- Warranty:2 years for quality issues
Our verdict“Pick this Asinking model if a documented water-resistance rating and roof-fit dimensions matter more to you than hard-shell security.”
Yakima SkyBox NX 18 XLG Rooftop Cargo Carrier
The SkyBox NX 18 XLG is the strongest fit here for SUV owners carrying long outdoor gear who prefer a rigid, lockable box over a soft bag. Its 84-inch length accommodates skis or snowboards up to 195 cm, and the flattened floor is intended to make more of the 18-cubic-foot interior usable. A dual-sided opening lets you load from whichever side is accessible, while SKS locks add a security advantage over the Asinking and MIDABAO bags. That structure comes with a practical cost: at 53 pounds, lifting it onto an SUV roof is more demanding than handling a soft carrier. The supplied description also says it is not water resistant, so for sustained heavy rain, the 20-cubic-foot Asinking bag has a clearer weather-protection case. Choose this for access and gear security, not maximum capacity or rain confidence.
Pros:- 84-inch length fits skis or snowboards up to 195 cm.
- Dual-sided opening makes loading easier when one side of the SUV is blocked.
- SKS locks secure the cargo and the box to the vehicle.
- Flattened interior floor is designed to improve usable packing space.
Cons:- At 53 pounds, installation and removal can be physically demanding.
- The supplied product details do not establish water resistance for heavy rain.
- Its 18-cubic-foot capacity is less than the soft Asinking and MIDABAO bags.
Best for: SUV owners transporting skis, snowboards, or camping gear who want a lockable rigid box and access from either side.
Not ideal for: Drivers who often face heavy rain, need a lighter carrier to install alone, or prioritize maximum storage volume.
- Capacity:18 cubic feet
- Dimensions:84 × 36 × 16.5 inches
- Weight:53 pounds
- Material:Plastic hard shell
- Opening:Dual-sided
- Lock:SKS lock
- Warranty:Limited lifetime
- Long-gear fit:Skis or snowboards up to 195 cm
Our verdict“Choose the Yakima if long gear, rigid storage, and two-sided access matter more than low weight or the soft bags’ larger capacity.”
MIDABAO 20-Cubic-Foot Waterproof Car Roof Cargo Bag
The MIDABAO’s appeal is straightforward: it offers 20 cubic feet of soft storage, a stated footprint, and a substantial strap set for SUVs with or without roof racks. Six short straps and two long straps give buyers several ways to secure a load, while the anti-slip mat helps separate the bag from the roof surface. That makes it a flexible alternative to the rack-dependent GarveeTech hard-shell box, especially for owners who do not already have crossbars. Its PVC-coated material and coated zippers are described as helping protect cargo from water, but the product details do not establish full waterproof performance in all conditions. Compared with the 20-cubic-foot Asinking bag, it provides dimensions and more strap detail, but lacks a stated IPX66 rating. Treat it as weather-conscious soft storage, not a guarantee for sensitive gear in prolonged rain.
Pros:- 20-cubic-foot capacity provides room for bulky trip luggage.
- Fits vehicles with or without roof racks.
- Listed dimensions help buyers check the roof footprint.
- Includes six short straps, two long straps, an anti-slip mat, and a storage bag.
Cons:- The supplied details do not establish full waterproof performance in all conditions.
- Soft-sided construction offers less structure than a hard-shell carrier.
- Strap-based installation needs careful tensioning to keep the bag stable.
Best for: SUV owners who need a roomy soft carrier that can be strapped down with or without a roof rack and want listed dimensions.
Not ideal for: Drivers carrying electronics or other rain-sensitive cargo who need a clearly specified waterproof rating or a rigid lockable shell.
- Capacity:20 cubic feet
- Dimensions:51.1 × 39 × 17 inches
- Material:PVC-coated
- Vehicle compatibility:Cars with or without roof racks
- Securing straps:6 short straps and 2 long straps
- Included accessories:Anti-slip mat and storage bag
- Model:M-02
Our verdict“Choose the MIDABAO if you want a roomy, rack-optional soft bag with a clearly listed footprint, but use added protection for rain-sensitive cargo.”
GarveeTech Rooftop Cargo Box Carrier with Dual-Side Opening
This GarveeTech box suits SUV owners who want a rigid, weather-protective carrier but do not need the volume of the 18-cubic-foot Yakima or the 20-cubic-foot soft bags. Its 12-cubic-foot capacity keeps the overall package more compact, while the ABS shell is described as waterproof and UV-resistant. Dual-sided access is useful when a garage wall or another parked vehicle blocks one side; the Yakima also opens from both sides, but offers more room and a larger footprint. This model requires a roof rack, unlike the Asinking and MIDABAO bags, so rack compatibility is a buying prerequisite rather than a minor detail. The listed maximum load is 165 pounds, but buyers still need to follow vehicle and rack limits. Only one side should be unlocked when opening, which calls for care during use.
Pros:- ABS hard shell is described as waterproof and UV-resistant.
- Dual-sided opening provides access from either side of the SUV.
- Compact 12-cubic-foot capacity can suit buyers who do not need a full-size box.
- Includes two keys and two straps.
Cons:- Requires a roof rack, so vehicle and rack fit must be checked.
- Offers less capacity than the Yakima SkyBox NX 18 XLG and the soft bags in this group.
- Only one side should be unlocked when opening.
Best for: SUV owners with a compatible roof rack who want a compact hard shell for everyday luggage and prefer two-sided access.
Not ideal for: Drivers without roof racks or families needing the larger capacity of the Yakima SkyBox NX 18 XLG or a 20-cubic-foot bag.
- Capacity:12 cubic feet (340 L)
- Dimensions:54.3 × 31.5 × 13.4 inches or 62.2 × 31.5 × 13.4 inches
- Material:ABS
- Maximum weight capacity:165 pounds
- Opening:Dual-sided
- Compatibility:Vehicles equipped with a roof rack
- Included accessories:2 keys and 2 straps
- Warranty:1 year
Our verdict“Pick this GarveeTech box if you have a compatible roof rack and want compact hard-shell storage with two-sided access.”
GarveeTech Rooftop Cargo Box, 12 Cubic Feet, Dual-Side Opening
For SUV owners who want a rigid box without taking up as much roof space as larger carriers, this 12-cubic-foot ABS shell offers a practical middle ground. Its dual-side opening can make loading easier when one side of the vehicle is blocked, while the included keys and straps cover basic security and cargo restraint. Compared with the Auto Dynasty Hard-Shell Rooftop Cargo Carrier, it offers one more cubic foot of stated capacity and access from either side, but Auto Dynasty specifies tool-free brackets and a 110-pound weight limit. This GarveeTech model lists a higher 165-pound maximum, though buyers still need to check their roof rack’s limits. The main tradeoff is that it requires a compatible roof rack, and only one side can be open at a time.
Pros:- Rigid ABS shell provides weather-resistant storage
- Dual-side access can suit different parking and loading situations
- 165-pound maximum load capacity is specified
- Includes two keys and two straps
Cons:- Requires a compatible roof rack
- One side must be locked while the other is open
- Warranty details are inconsistent, listing both one year and 30 days
Best for: SUV owners with a compatible roof rack who want a hard-shell carrier with flexible access and moderate capacity.
Not ideal for: Drivers without a roof rack or those who want a larger carrier for bulky family luggage.
- Material:ABS
- Capacity:12 cubic feet (340 L)
- Maximum weight capacity:165 lbs
- Dimensions:54.3 × 31.5 × 13.4 in
- Opening:Dual-sided
- Compatibility:Vehicles with a roof rack
- Included accessories:2 keys and 2 straps
- Warranty:Product details state one year and also 30 days
Our verdict“Choose this for compact, dual-access hard-shell storage if your SUV already has a compatible rack and you verify the warranty terms.”
FIVKLEMNZ 21-Cubic-Foot Waterproof Soft Rooftop Cargo Carrier
When an SUV trip calls for space for bulky bags, this carrier’s 21-cubic-foot capacity exceeds the hard-shell options in this batch, including the 12-cubic-foot Garvee models. Its 840D PVC, welded seams, and double-layer cover are intended to shield luggage from rain and snow, while the broad vehicle compatibility includes cars, SUVs, vans, and trucks with or without roof racks. The included anti-slip mat, door hooks, straps, lock, and storage bag make it a fuller kit than the simpler hard-shell boxes. That flexibility has a cost in rigidity: unlike the ABS Auto Dynasty carrier, the soft sides offer less protection from impacts and need to be secured carefully. Buyers should also be comfortable routing straps and hooks rather than relying on a fixed rack-mount system.
Pros:- Large 21-cubic-foot capacity for bulky travel gear
- 840D PVC construction with welded seams and a double-layer cover
- Fits vehicles with or without roof racks
- Includes an anti-slip mat, door hooks, straps, lock, and storage bag
Cons:- Soft-sided construction offers less impact protection than a hard-shell box
- Installation depends on correctly securing multiple straps and door hooks
- Large dimensions may be awkward on smaller vehicle roofs
Best for: SUV-owning families and road-trippers who need high luggage capacity and may use a vehicle without a roof rack.
Not ideal for: Drivers seeking rigid impact protection or a quick, bracket-based installation on crossbars.
- Capacity:21 cubic feet
- Dimensions:52 × 40 × 18 in
- Material:840D PVC
- Attachment:10 reinforced straps and 6 door hooks

Our verdict“Pick this soft carrier when capacity and broad vehicle compatibility matter more than hard-shell impact protection.”
Auto Dynasty Hard-Shell Rooftop Cargo Carrier
The Auto Dynasty is a straightforward choice for SUV owners whose crossbars fit its stated limits: tool-free mounting brackets avoid a tool-dependent setup, and its passenger-side opening puts access on a single, defined side. Its 11-cubic-foot capacity is smaller than the 12-cubic-foot GarveeTech and Garvee boxes, and its 110-pound limit is lower than their stated 165-pound limits. In return, the product gives buyers specific crossbar guidance—up to 13 inches wide—and a defined opening side, details that help narrow compatibility before purchase. The UV-protected ABS shell and key lock suit travelers who prefer a rigid enclosure over the larger soft FIVKLEMNZ bag. It is less flexible if your crossbars are wider than the stated limit or you need access from both sides.
Pros:- Tool-free mounting brackets simplify installation on compatible crossbars
- Weather-resistant, UV-protected ABS construction
- Passenger-side opening gives a defined loading side
- Includes two security keys and four mounting brackets
Cons:- Crossbars must be no wider than 13 inches
- 110-pound weight limit is lower than the Garvee hard-shell options listed here
- 11-cubic-foot capacity is smaller than the 12-cubic-foot Garvee boxes
Best for: SUV drivers with crossbars no wider than 13 inches who want a rigid box and simple, tool-free bracket mounting.
Not ideal for: Owners with wider crossbars, heavier cargo needs, or a preference for dual-side access.
- Material:UV-protected, weather-resistant ABS
- Capacity:11 cubic feet
- Weight limit:110 lbs
- Dimensions:53 × 34 × 15 in
- Opening width:14 in
- Crossbar compatibility:Up to 13 in wide
- Opening side:Passenger side
- Installation:Tool-free mounting brackets
- Included:Cargo box, 2 security keys, and 4 mounting brackets
Our verdict“Choose Auto Dynasty if its crossbar limit fits your SUV and you value tool-free mounting over extra capacity or two-sided access.”
Garvee Rooftop Cargo Box Carrier with Dual-Side Opening
This Garvee stands out for combining a waterproof, UV-resistant ABS shell with dual-side access, a useful pairing for SUV owners who want enclosed storage and flexibility at the curb. Its 12-cubic-foot capacity and 165-pound maximum load match the GarveeTech 12-cubic-foot box in this roundup, and both list the same dimensions and included keys and straps. The stated waterproof and UV-resistant finish gives this model more specific weather-protection claims than the GarveeTech description, but the core fit and capacity are nearly identical. That makes roof-rack compatibility the deciding practical check: this box does not remove the need for a suitable rack. One side also has to remain locked while the other is open, so dual-side access means choosing which side to use rather than opening both at once.
Pros:- Waterproof and UV-resistant ABS shell
- Dual-side opening provides access from either side of the SUV
- 165-pound maximum load capacity is specified
- Includes two keys, two straps, and a one-year warranty
Cons:- Requires a compatible roof rack, which should be checked before purchase
- Only one side can be open at a time
- Offers the same 12-cubic-foot capacity and dimensions as the GarveeTech model
Best for: SUV owners with a suitable roof rack who want a weather-resistant hard shell and the option to load from either side.
Not ideal for: Drivers without a compatible rack or shoppers looking for meaningfully more capacity than a compact box.
- Material:ABS
- Storage capacity:12 cubic feet (340 L)
- Maximum load capacity:165 lbs
- Dimensions:54.3 × 31.5 × 13.4 in
- Opening:Dual-sided
- Compatibility:Vehicles equipped with a roof rack
- Weather resistance:Waterproof and UV-resistant
- Included accessories:2 keys and 2 straps
- Warranty:1 year
Our verdict“Pick this Garvee when its stated weather protection and dual-side access fit your needs and your SUV’s roof rack is compatible.”
15-Cubic-Foot Waterproof Car Rooftop Cargo Carrier Bag
This bag suits SUV owners who need more room than a compact hard-shell box but do not need the FIVKLEMNZ carrier’s full 21 cubic feet. Its 15-cubic-foot capacity and compatibility with vehicles with or without roof racks offer a useful middle ground, while the 840D PVC fabric, welded seams, and waterproof zipper with wide Velcro flaps are designed to limit water entry. The included anti-slip mat, six door hooks, extra luggage straps, and storage bag provide more securing accessories than the basic straps supplied with the Garvee hard-shell boxes. But unlike those rigid boxes, it cannot offer the same impact protection, and the product data gives no dimensions or weight limit. That missing fit information makes roof space and load planning harder before purchase.
Pros:- 15-cubic-foot capacity sits between compact boxes and larger soft carriers
- Compatible with vehicles with or without roof racks
- 840D PVC fabric with reinforced welded seams
- Includes an anti-slip mat, door hooks, extra straps, storage bag, and luggage lock
Cons:- No dimensions or weight limit are provided
- Soft construction offers less impact protection than the ABS Garvee boxes
- Waterproof performance is stated by the manufacturer and not independently verified
Best for: SUV travelers who want a mid-capacity soft carrier that can attach to vehicles with or without roof racks.
Not ideal for: Buyers who need a stated weight limit, precise dimensions, or rigid protection for fragile cargo.
- Capacity:15 cubic feet
- Material:840D abrasion-resistant PVC fabric
- Waterproof features:Waterproof zipper with 6-inch-wide Velcro flaps and reinforced welded seams
- Roof rack compatibility:Vehicles with or without roof racks
- Included accessories:Anti-slip mat, 6 door hooks, 2 extra luggage straps, storage bag, and luggage lock
Our verdict“Choose this bag for flexible, mid-capacity roof storage when rack-free compatibility matters more than rigid protection or precise load specifications.”
How We Picked
I compared the 15 listed carriers by the factors that affect SUV ownership most: usable capacity, access, construction, mounting requirements, storage, and fit checks. I treated hard-shell boxes and soft cargo bags as different solutions rather than ranking them as if they offered the same structure or storage experience. Capacity mattered, but a larger number did not automatically put a product ahead; a carrier also needs an opening and mounting setup that works with the vehicle.
The order gives priority to options with a clear combination of practical access, a defined capacity, and a recognizable use case, which puts the Thule Pulse 2 M first for balanced everyday use. The Yakima SkyBox NX 18 XLG and SportRack Vista XL follow for buyers who value larger enclosed volume or rear access. Soft bags and less fully specified box listings rank lower because shoppers must pay closer attention to roof compatibility, weather exposure, and the exact hardware or dimensions in the product listing.
Factors to Consider When Choosing Rooftop Cargo Box For Suv
Choosing a rooftop carrier is a vehicle-fit decision as much as a capacity decision. I’d check the SUV’s roof limits and your loading routine before comparing advertised volume, then decide whether a rigid box or a packable bag better suits how often you travel.
Check Roof Load Limits Before Capacity
Start with the SUV manual, not the cargo carrier listing: the vehicle’s roof-load limit applies to the combined weight of the carrier and its contents. Crossbars also have their own limits, and the lowest applicable rating sets the practical ceiling. A large 20- or 21-cubic-foot bag can invite overpacking even when the roof cannot support a heavy load. Weigh the carrier, crossbars if relevant, and cargo together, and distribute items evenly. Keep dense gear inside the vehicle when roof capacity is tight. This step matters more than choosing between nearby capacity claims.
Match the Carrier to Your Roof Setup
Do not assume a product described as fitting SUVs will attach to every SUV roof. Some carriers depend on crossbars, while soft bags may list use with or without a rack but still need a secure, approved attachment method for your vehicle. Check the product’s mounting instructions against your roof type, crossbar spacing, and any sunroof or antenna restrictions. Measure the roof area and confirm the attachment points will not interfere with the hatch. A mismatch can make loading awkward or prevent secure installation. When a listing is vague, verify the exact included straps and hardware before choosing it.
Choose Access Around Your Loading Routine
Opening style affects more than convenience: it can determine whether you can reach cargo while parked beside another vehicle or standing behind the SUV. Dual-side openings, such as those listed for the Thule Pulse 2 M and several Garvee models, give more options when parking conditions change. A rear-opening design like the SportRack Vista XL may suit drivers who usually load from the back. Check whether your hatch can open fully with the carrier installed, especially on vehicles with a tall liftgate. Think about who will load the box and how heavy the items are. A large carrier with inconvenient access can be less useful than a smaller one that fits your routine.
Decide Between a Hard Box and a Soft Bag
A hard-shell box offers a structured enclosure that keeps its shape, while a soft bag can be easier to fold and store between trips. That storage difference matters for apartment dwellers or anyone without room for a bulky box. Soft carriers also need careful packing so sharp corners do not press against the fabric, and straps must hold the load securely. A rigid box takes more space at home and can be harder to handle when off the vehicle. Neither format removes the need to follow the maker’s weather and mounting directions. Choose based on where the carrier will live for most of the year, not just on the drive to your destination.
Treat Weather Protection as a Setup, Not a Label
Terms such as waterproof describe a product claim, not a guarantee that every trip’s contents will stay dry. Fit, closure, seam design, loading, and exposure all influence how a soft carrier performs in rain. Pack clothing and other sensitive items in separate waterproof liners, especially for long drives or uncertain weather. With a hard box, check that the lid closes cleanly and that cargo does not block the seal. Avoid placing items where they can press against closures or create an uneven top. If you carry electronics, documents, or other moisture-sensitive gear, add a second layer of protection rather than relying on the outer shell alone.
Measure Clearance and Plan for Storage
Measure the SUV with the carrier mounted and account for the extra height before entering garages, parking structures, or drive-throughs. The carrier can also affect hatch access and the vehicle’s handling, particularly when loaded or exposed to crosswinds. Compare the listed external dimensions, not just cubic feet, because two carriers with similar volume may occupy different roof lengths. A box that extends too far forward can affect access or create fit problems, while one that reaches over the hatch may restrict opening. Before buying, decide where a hard box will be stored when unused; soft bags fold down but still need to dry fully before packing away. These checks help avoid choosing capacity that your SUV cannot use comfortably.
Frequently Asked Questions
Can I use a soft rooftop cargo bag on an SUV without crossbars?
Some listed bags are advertised for vehicles with or without a rack, but that claim does not confirm compatibility with every roof design. Check the maker’s installation instructions for the approved attachment points and whether the bag can sit safely on your specific roof. Confirm that straps will not cross or damage doors, seals, antennas, or a sunroof. Also check the SUV manual for roof-load limits and any restrictions on carrying cargo without crossbars. If the instructions do not clearly cover your vehicle setup, choose a carrier designed for your roof system instead of improvising.
How do I know whether a 20- or 21-cubic-foot carrier is too large for my SUV?
Capacity alone cannot answer that: compare the carrier’s external length, width, and height with the usable roof area and your vehicle’s roof-load limit. Check crossbar placement, hatch clearance, and whether the carrier can be centered and secured using its prescribed mounting points. A larger bag can also tempt you to pack more weight than the roof can support. Lay out the gear you plan to carry and estimate its weight before choosing the biggest volume. If the load is light but bulky, a large carrier may help; for dense cargo, a smaller one may be the safer match.
Should I choose a hard-shell box or a soft rooftop bag for occasional trips?
For occasional use, a soft bag can make sense if compact storage is a priority and its mounting method suits your SUV. A hard box is a better fit when you want a rigid enclosure and expect to use the carrier regularly, but it needs more storage space when removed. Consider how often you can dry and repack a bag after wet travel, as storing it damp can cause problems. Also think about loading: a box keeps its shape, while a bag depends on careful packing and secure straps. Your storage space and trip frequency are better decision points than the carrier’s capacity figure alone.
Will a rooftop cargo box block my SUV’s rear hatch?
It can, depending on the carrier’s length, mounting position, and the angle of your SUV’s liftgate. Compare the carrier’s external dimensions with the roof and measure how far the hatch swings upward before buying. Rear-opening models may offer convenient loading from behind, but the box still needs enough clearance for the hatch itself. When possible, check the manufacturer’s fit guidance for your vehicle and crossbar position. Do not assume that a box marketed for SUVs will clear every SUV hatch.
How should I protect luggage in a soft cargo carrier during heavy rain?
Follow the bag maker’s closure and installation directions, and avoid packing the carrier so tightly that its seams or closures are strained. Put clothing and moisture-sensitive items in separate waterproof liners as a second layer, then position cargo so hard edges do not rub against the fabric. Check that straps are secure and the bag sits correctly on the roof before setting off. After travel in wet weather, remove the bag and dry it fully before storage. These steps reduce exposure, but they cannot turn a product claim into a guarantee for every storm or driving condition.
Conclusion
For the best overall balance, I’d choose the Thule Pulse 2 M for its 14-cubic-foot capacity and dual-side access. The best larger hard-shell option in this lineup is the Yakima SkyBox NX 18 XLG, while drivers who load from the rear should compare the SportRack Vista XL. For a best value-style choice, I’d focus on the soft bags if pack-away storage and a compatible roof setup matter more than a rigid enclosure; compare the Asinking, Sailnovo, MIDABAO, and FIVKLEMNZ listings by dimensions and mounting details. The best beginner choice is the carrier whose fit instructions clearly match your SUV and whose loading style is easy for you to manage, rather than simply the largest option. For specific needs, choose dual-side access for flexible parking, rear access for back-of-vehicle loading, or a foldable bag when home storage is limited. Before deciding, confirm roof-load limits, hatch clearance, and attachment compatibility.
