10 Best Cargo Boxes for Subaru Forester in 2026: Practical Picks for More Storage

A rooftop cargo box can free up valuable cabin space in a Subaru Forester without leaving luggage exposed to the elements. The right choice depends on more than volume: it also needs to fit your crossbars, clear the rear hatch, and carry your gear within the vehicle’s roof-load limit.

These 10 options span compact and larger boxes, different opening styles, and a range of weight ratings. Use the comparisons below to narrow down a box that suits your trips and your specific Forester setup.

Best 10 Cargo Box for Subaru Forester Picks for 2026

Best for Dual-Side Access – GarveeTech 12 Cu. Ft. Cargo Box

If you’re shopping for a cargo box for Subaru Forester road trips, this GarveeTech model offers 12 cubic feet of storage and access from either side. Its ABS hard shell measures 54.3 x 31.5 x 13.4 inches; check your Forester’s crossbar fit and roof-load limit before buying.

Best For: Travelers who want to load luggage from either side of the vehicle.

Pros:

• Dual-side opening makes loading more flexible.
• Waterproof, UV-resistant ABS shell.
• Includes two keys and two securing straps.

Cons:

• At 39 pounds empty, the box uses part of your roof’s available load capacity.
• Roof-rack compatibility needs to be verified before purchase.

The stated box capacity is 165 pounds, but your usable load may be lower once you account for the vehicle and rack limits. Warranty information in the supplied notes conflicts, so confirm coverage with the seller.

Best for Bulky Luggage – SportRack Vista XL

For shoppers seeking a cargo box for Subaru Forester trips with lots of luggage, the SportRack Vista XL provides 18 cubic feet of space. Its rear-opening lid lets you reach gear from behind the vehicle, while the included hardware mounts without tools.

Best For: Families prioritizing storage volume and rear access.

Pros:

• 18-cubic-foot capacity accommodates bulky packing.
• Rear opening keeps access away from the sides of the vehicle.
• Tool-free mounting hardware and a key-operated lock are included.

Cons:

• 100-pound box load limit is lower than the stated limit of some smaller boxes.
• Requires crossbar spacing of 23 5/8 to 29 3/4 inches; check the fit guide.

Measure your Forester’s crossbars and check hatch clearance before choosing this large box. The vehicle and rack load limits may further restrict how much you can carry.

Best Compact Option – 10 Cu. Ft. Rooftop Cargo Carrier

If you need a smaller cargo box for Subaru Forester travel, this 10-cubic-foot carrier measures 46.5 x 30.5 x 17.5 inches. Its HDPE hard shell has a weather-tight seal and opens from either side for loading.

Best For: Drivers who need modest extra storage and dual-side access.

Pros:

• Dual-side opening helps with loading and unloading.
• Weatherproof shell has a locking system and front latch.
• Includes mounting hardware and requires no tools for assembly.

Cons:

• 10-cubic-foot capacity offers less room than the larger boxes here.
• The listing specifies vehicle-specific fit, so Forester compatibility must be confirmed.

Its stated load capacity is 110 pounds, subject to your vehicle and rack limits. Verify the required mounting fit before ordering rather than assuming the included hardware suits your crossbars.

Best for Quick Mounting – Thule Pulse Medium

The Thule Pulse Medium is a 14-cubic-foot cargo box for Subaru Forester owners who value straightforward mounting. Its FastGrip system is designed to assemble in minutes, and the passenger-side opening gives you one designated side for loading.

• Central Locking system prevents key removal until all locking points are closed.
• Fits three to five snowboards up to 155 cm long.

Cons:

• Listed as water-resistant, not waterproof.

At 67 inches long and 16 inches high above the crossbar, this box warrants a check of hatch and overhead clearance. Confirm crossbar compatibility and roof-load limits; its stated box load capacity is 110 pounds.

Most Storage – 18 cu. ft. Hard-Shell Carrier

If you need a high-volume cargo box for Subaru Forester trips, this 18-cubic-foot carrier offers room for luggage in a 57 x 39 x 19.5-inch hard shell. Check its mounting fit and your vehicle’s roof-load limit before buying.

Cons:

• 110-pound stated cargo capacity is lower than the Garvee box’s 165-pound rating.
• Rear loading offers less flexibility than dual-sided access.

Its capacity is the main draw, but confirm crossbar compatibility and account for both the box and its contents when checking roof-load limits.

Best for Long Gear – Yakima RocketBox Pro 14

For shoppers comparing a cargo box for Subaru Forester travel, the Yakima RocketBox Pro 14 offers a 74-inch-long, 14-cubic-foot shell that may suit longer items. Its dual-sided opening lets you load from whichever side is easier to reach.

If load capacity is a priority in a cargo box for Subaru Forester travel, this 14-cubic-foot Garvee model lists a 165-pound maximum. It has a 62.2 x 31.5 x 13.4-inch ABS shell and opens from either side.

The box’s stated capacity does not raise your Forester’s roof-load limit. Confirm the rack fit, vehicle limits, hatch clearance, and warranty terms before ordering.

Compact Universal Pick – Auto Dynasty 11-Cubic-Foot Cargo Box

If you need a cargo box for Subaru Forester trips, this 53-inch Auto Dynasty box adds 11 cubic feet of storage without taking up cabin space. It has a universal crossbar mount, so check your Forester’s crossbars against the stated fit before buying.

How We Picked the Best Cargo Box for Subaru Forester

We compared the listed boxes on the factors that matter most to Forester owners: stated storage volume and load rating, opening direction, locking design, mounting requirements, and overall dimensions where available. We also considered whether a box’s shape could make rear-hatch access or parking-garage clearance harder. Product listings alone cannot establish a universal fit, so treat model-year compatibility claims as a starting point—not a substitute for checking your vehicle and crossbars.

Quick Comparison

For a relatively compact setup, start with the 10-cu.-ft. carrier or the medium Thule Pulse. The Yakima RocketBox Pro 14 offers a stated 14 cu. ft. for buyers who need more room without automatically choosing the largest box. The listed 18-cu.-ft. carrier and SportRack Vista XL are worth considering when packing bulky family gear; check their exterior dimensions before ordering. Dual-side-opening Garvee and GarveeTech options may be easier to access when parking space is tight, while the rear-opening SportRack requires room behind the vehicle. Compare the actual listing for each box: names, dimensions, mounting hardware, and specifications can vary by seller.

Key Buying Factors for a Cargo Box for Subaru Forester

Crossbars and Fit

A roof box attaches to crossbars, not simply to the Forester’s side rails. Confirm that your vehicle has compatible crossbars and that their shape, width, spacing, and load rating meet the box manufacturer’s requirements. A listing that names particular Forester years does not guarantee compatibility with other model years or aftermarket racks.

Roof Load and Usable Capacity

The vehicle, crossbars, and box can each have different weight limits; follow the lowest applicable limit. Include the empty box and mounting hardware when calculating how much gear you can carry. A box advertised with a 110- or 165-lb. capacity does not raise your Forester’s permitted roof load. Put dense, heavy items inside the vehicle when practical and reserve the box for lighter, bulky gear.

Clearance, Access, and Security

Check box length and mounting-position adjustment so the open rear hatch will not strike it. Measure total vehicle height with the box installed before entering a garage or low-clearance area. Dual-side openings can improve access from either side; rear-opening models may suit some parking situations but need space behind the car. Choose a locking box for basic theft deterrence, and verify that the lid is fully latched before every drive. Weatherproof claims are not a reason to leave sensitive items unprotected inside.

Who Should Buy Which Cargo Box for Subaru Forester?

Occasional travelers with modest luggage should prioritize a smaller box that is easier to store and less likely to interfere with the hatch. Families carrying jackets, bedding, or other bulky equipment should compare larger-volume choices against their roof-load budget. Buyers who often park against walls may appreciate dual-side access. If you have a 2014–2018 Forester, the year-specific DNA MOTORING listing is worth checking, but confirm its fit against your exact rack setup. Whatever you choose, verify the current specifications and installation instructions before purchase.
