Best Cargo Box For Subaru Outback: 10 Options Compared

#1 · Best Overall

1. Generic Car Roof Cargo Box

• Dimensions: 46.1"L x 15.55"W x 7.08"H
• Material: Plastic

Best for: Small-volume camping storage.

Why it ranks #1: Its title explicitly identifies Subaru Outback fit, and its 60 L capacity and 46.10-inch length suit buyers prioritizing a vehicle-specific listing.

A 60-litre capacity in a 46.10-by-15.55-by-7.08-inch case gives this lockable rooftop box a compact storage footprint for Outback travel. It can hold camping gear, luggage, or sports equipment, freeing cabin room, while its waterproof description suits trips where exposed cargo is a concern.

The 60-litre capacity and 7.08-inch height make this a compact option for moving selected items out of the passenger area rather than a high-volume luggage carrier. Its listed 46.10-by-15.55-inch footprint helps buyers assess the space it occupies on the roof. The product is described as waterproof, and its plastic construction is specified. The listing also mentions an interlocking design and use for tools and dry goods, including back seats, trunks, and truck beds, though those uses extend beyond rooftop travel.

Skip it if you need substantially more roof storage; the SportRack Vista XL offers 18 cubic feet.

This compact box suits Outback owners who want to carry selected camping or sports items outside the cabin rather than pack a large volume of luggage. Its 60-litre capacity is the key boundary when planning a family trip.

#2 · Longest Box

2. Thule Force 3 XL

• Dimensions: 89"L x 18"W x 40"H
• Material: Plastic
• Weight: 65 lb

Best for: Large-box two-side access.

Why it ranks #2: The 89-inch length and two-sided access suit longer loads and convenient loading, while the quick mounting system indicates secure attachment.

The 89-inch Thule Force 3 XL pairs a long cargo box with access from both sides of the Outback, helping make a large roof load reachable from either side. Its mounting system indicates secure attachment with a click, giving installation a clear confirmation cue.

The 89-by-18-by-40-inch dimensions establish a substantial roof footprint, so buyers can compare the box with available space before choosing it. Dual-side access allows loading or retrieval from either side of the vehicle, while the quick mounting system clicks to indicate secure attachment. The product description emphasizes durability for daily use, and Thule says it was tested for road safety and durability in its Test Center. The supplied details do not state a cargo volume or load capacity.

Skip it if you need a stated capacity before comparing cargo limits; the DNA Motoring PT-ZTL-8295-BK lists 17 cubic feet and 110 pounds.

The Force 3 XL suits Outback drivers who want a long box, two-sided access, and a click-indicating mount for everyday or active trips. Its listed dimensions are substantial, and cargo volume and load capacity are not supplied.

#3 · Rear Access

3. SportRack Vista XL

• Material: Plastic

Best for: Rear-access family gear hauler.

Why it ranks #3: Its 18 cubic feet provide substantial space, and rear opening offers access away from traffic; mounting fits most factory racks, subject to fit checking.

Rear opening keeps the SportRack Vista XL’s 18 cubic feet of storage accessible from the back of the vehicle, away from passing traffic. That arrangement suits drivers who load curbside or at busy stops, while the UV-resistant ABS shell and included lock address outdoor exposure and security.

The 18-cubic-foot capacity gives an Outback owner room to move luggage and trip gear out of the cabin, while the rear-opening lid keeps access at the back rather than beside traffic. Tool-free mounting hardware simplifies putting the box on or taking it off the rack. The ABS construction is UV-resistant, and the included lock secures both the contents and the box to the rack. It fits SportRack, square, round, and most factory racks; crossbar spacing is listed as 23 5/8 inches minimum.

Skip it if you need dual-side loading; the Thule Pulse 2 L opens from either side of the vehicle.

Choose the Vista XL if your Outback trips call for 18 cubic feet and you prefer rear access away from traffic. Its mounting compatibility covers several rack types, but check the listed crossbar spacing against your setup.

#4 · Dual-Side Access

4. Thule Pulse 2 L

• Dimensions: 81"L x 17"W x 37"H
• Material: Plastic

Best for: Everyday dual-side access.

Why it ranks #4: It provides 450 litres, a 75 kg load capacity, and access from either side, with tool-free mounting and a torque indicator.

Dual-side opening lets the Thule Pulse 2 L reach cargo from either side of the Outback, a practical advantage when parking or loading conditions change. Its 450 litres of space and 75 kg load capacity suit commuting, day trips, and weekend gear without requiring a single-side approach.

The torque-indicator mounting system clicks when the box is safely attached, giving installation a clear confirmation instead of relying only on feel. Its closure confirmation also helps verify that the lid is shut before departure. With access from either side, passengers can reach luggage without walking around the vehicle, while the 450-litre capacity accommodates luggage, gear, skis, or snowboards. The streamlined shape is specified for a wide variety of modern vehicles, though the supplied details do not state Outback-specific fitment.

Skip it if you need a stated crossbar spacing range before choosing; the GarveeTech 14-cubic-foot box lists one.

The Pulse 2 L suits Outback drivers carrying everyday luggage or weekend equipment who value two-sided access and attachment feedback. Its listed details do not give a crossbar spacing range, so that is a key fit consideration.

#5 · High Capacity

5. DNA Motoring XXL Cargo Box

• Dimensions: 78"L x 31"W x 15"H
• Material: Acrylonitrile Butadiene Styrene (ABS)

Best for: Long-load 17-cubic-foot carrier.

Why it ranks #5: The 17 cubic-foot interior and 110-pound maximum capacity suit bulky trip gear, but compatibility is stated only for vehicles with crossbars.

The DNA Motoring box combines 17 cubic feet of space with a 78-inch length, giving Outback owners room to consider longer or bulkier travel cargo. It opens up to 14 inches wide, carries a stated 110-pound maximum when evenly distributed, and includes mounting brackets and keys.

Its 78-by-31-by-15-inch dimensions and 17-cubic-foot volume make this an option for buyers who want a long cargo area above the Outback. The lid opens up to 14 inches wide to accommodate bulky items, while the stated 110-pound capacity applies when weight is evenly distributed. The ABS construction is described as impact-resistant. The listing specifies crossbar-only fit and no-tool installation, and includes four ABS mounting brackets and a pair of keys for setup and locking.

Skip it if you want dual-side access specifically; the Thule Pulse 2 L opens from either side.

Pick this DNA Motoring box for an Outback trip where long cargo and 17 cubic feet matter, and distribute loads evenly within its 110-pound limit. Its listed fit is for vehicles with crossbars, and the 78-inch length merits roof-space planning.

6. INNO Wedge 660

• Dimensions: 80"L x 33"W x 11"H
• Material: Plastic
• Weight: 42 lb

Best for: Low-profile ski trip carrier.

Why it ranks #6: Its 11 cubic feet, 80-inch length, and dual-side opening suit skis and snowboards; the listing specifies aero and square bar compatibility.

At 11 inches high, the INNO Wedge 660 offers a low-profile hard shell that can carry up to four snowboards or six to eight pairs of skis. Its dual-side opening supports loading from either side of an Outback, making it particularly relevant for winter-sports trips.

The 11-cubic-foot capacity is smaller than many luggage-focused boxes, but the listed ski and snowboard capacity makes its intended use concrete: up to four snowboards or six to eight pairs of skis. Its 80-by-33-by-11-inch dimensions give buyers a way to compare roof space and cargo shape. Dual-side opening eases access from either side, while tool-free installation and compatibility with aero and square bars simplify setup for those rack types. The aerodynamic design is described as reducing noise.

Skip it if you need 17 cubic feet for bulky luggage; the DNA Motoring PT-ZTL-8295-BK lists that capacity.

The Wedge 660 is a good match for Outback owners prioritizing ski or snowboard storage over maximum luggage volume. Its low 11-inch profile and two-sided access help with winter gear, while rack compatibility is specified for aero and square bars.

7. GarveeTech Cargo Box

• Dimensions: 62.2"L x 31.5"W x 13.4"H
• Weight: 44.8 lb

Best for: Crossbar-measured compact hauler.

Why it ranks #7: The 14-cubic-foot version lists crossbar spacing of 20.5 to 30.3 inches and bar-width limits, useful details for checking rack compatibility.

Published crossbar limits make this GARVEETECH box easier to assess against a roof rack before installation: its 14-cubic-foot configuration specifies spacing from 20.5 to 30.3 inches. Dual-side access and a weather-resistant ABS shell add useful loading flexibility and protection for road-trip cargo.

The 14-cubic-foot configuration lists crossbars 20.5 to 30.3 inches apart, with a width range of 1.1 to 3.3 inches and height range of 0.7 to 1.5 inches. Those measurements let buyers compare a rack with stated requirements before mounting. The dual-side-opening design provides access from either side of the Outback, while the waterproof, UV-resistant ABS shell is specified to protect luggage from weather. The aerodynamic shape is also described as reducing noise and fuel consumption.

Skip it if you want mounting hardware explicitly listed as included; the SportRack Vista XL includes its mounting hardware.

Consider this GARVEETECH option if you want dual-side loading and can compare your Outback’s crossbars with its published dimensions. The listed compatibility ranges apply to the 14-cubic-foot configuration, so verify those measurements against your rack.

#8

8. Garvee Cargo Box

• Dimensions: 62.2"L x 31.5"W x 13.4"H
• Weight: 43 lb

Best for: Lockable two-side loading.

Why it ranks #8: Its 14-cubic-foot size, dual-sided access, and included lock offer practical utility, though the listing gives no specific Outback rack-fit measurements.

A lock that secures both cargo and the box to the vehicle gives the Garvee rooftop carrier a clear security feature for parked travel stops. Its dual-sided opening lets Outback occupants load from either side, while the 14-cubic-foot configuration offers a substantial roof-storage option.

The dual-sided opening makes it possible to reach luggage from the curb or opposite side of the Outback, but the supplied instructions say not to open both sides simultaneously. A lock secures the contents and helps keep the box attached to the vehicle. The ABS shell is described as waterproof and UV-resistant, supporting use in varied weather, and the aerodynamic shape is intended to reduce noise and fuel consumption. The listed 62.2-by-31.5-by-13.4-inch dimensions provide a basis for checking roof space.

Skip it if you want crossbar spacing limits published; the GARVEETECH 14-cubic-foot model lists a spacing range.

This Garvee fits buyers who value two-sided access and a lock for travel gear, provided they follow the instruction not to open both sides at once. Compare its listed dimensions with your Outback’s roof and rack.

#9

9. INNO Ridge Cargo Box

• Dimensions: 50.4"L x 23.6"W x 11.4"H
• Material: Blend
• Weight: 20 lb

Best for: Lightweight short-trip carrier.

Why it ranks #9: At 8 cubic feet and 50.4 inches long, it is the compact hard box here and lists compatibility with aero, square, round, and most factory racks.

At 20 pounds and 8 cubic feet, the INNO Ridge is a relatively light, compact roof box for Outback drivers carrying a smaller load. Its aerodynamic design is intended to reduce noise, and the safety lock key cannot be removed until the box is locked.

The 50.4-by-23.6-by-11.4-inch dimensions and 8-cubic-foot capacity suit buyers who need a defined, smaller cargo space rather than a large luggage box. At 20 pounds, the listed weight is a practical consideration when handling the box for installation or removal. Its universal-fit description covers aero, square, round, and most factory racks. The aerodynamic form is specified for noise reduction, and the safety lock system keeps the key captive until the box is locked.

Skip it if you need room for bulky family luggage; the SportRack Vista XL offers 18 cubic feet.

Choose the Ridge for an Outback setup where modest storage, broad rack-type compatibility, and a 20-pound box matter more than maximum volume. Its 8-cubic-foot capacity is the main constraint for longer trips with bulky gear.

#10

10. D Solutions Roof Cargo Box

• Dimensions: 53"L x 34"W x 15"H
• Material: ABS Plastic
• Weight: 50.3 lb

Best for: Crossbar-only weather protection.

Why it ranks #10: This 53-inch ABS box is described as universal for vehicles with crossbars, but supplies no Outback-specific fit guidance or stated cargo volume.

A stated 110-pound loading capacity gives this D SOLUTIONS hard shell a clear carrying limit for roof cargo. Its ABS construction is described as protecting contents from inclement weather, while the 53-by-34-by-15-inch box offers a defined footprint for Outback owners to assess.

The box measures 53 by 34 by 15 inches, and the stated 110-pound loading bearing gives buyers two concrete checks when planning cargo and roof space. Its ABS shell is described as durable and able to help protect contents from inclement weather. The universal fit claim is limited to vehicles with crossbars, and the listing describes installation as requiring no tools. The strong support arm is another specified feature, though the supplied information does not provide crossbar spacing limits.

Skip it if you need a box with stated crossbar spacing limits; the GARVEETECH 14-cubic-foot model provides them.

This D SOLUTIONS carrier suits Outback owners with crossbars who want a weather-protective ABS shell and a stated 110-pound load limit. The listing does not give a crossbar spacing range, so rack measurements remain a fit consideration.
