3. INNO BRM320 9 Cu Ft Rooftop Cargo Box (Matte Black)
| Mounting Type | Roof Mount |
|---|---|
| Item Volume | 9 Cubic Feet |
| Shell Type | Hard |
| Automotive Fit Type | Universal Fit |
| Included Components | BRM320MBK, Locks, Keys Incl |
The INNO BRM320 is a compact hard-shell cargo box that adds about 9 cu ft of secure roof storage for weekend gear or extra luggage. It installs with INNO’s Memory Mount clamp system that lets you set the clamp positions once and clamp the box to crossbars quickly without tools, and the dual-side opening makes loading easier from either side of the vehicle. The matte black shell is low profile, which reduces wind noise and makes it more likely to clear a garage or door opening on taller vehicles. Typical uses are ski trips, camping, and family road trips where you need extra protected storage but do not want a bulky box. Limitations are its modest internal length and capacity for long skis or very large items, and it may not fit if your Traverse has unusual roof accessories or very wide crossbars. Expect good build quality and simple seasonal mounting but plan your packing around the box’s compact footprint.
Best for: Risk-averse mainstream buyers who prioritize a factory-quality, easy-to-use cargo solution that minimizes wind noise and garage clearance issues while adding modest extra storage.
Less Ideal for: Buyers who need maximum cargo volume or who regularly transport long items that exceed the box’s compact internal length should consider larger or longer models instead.
- Low profile hard-shell design that reduces wind noise and improves aerodynamics
- Memory Mount clamp system for faster, tool-free mounting and repeatable fit
- Dual-side opening for easier loading from either side of the vehicle
- Locks and keys included for secure, lockable storage
- Limited internal length can make fitting long skis or very large items difficult
- Smaller 9 cu ft capacity may not handle bulky family loads
Verdict A well-built, low-profile 9 cu ft cargo box that delivers secure, low-noise storage and fast tool-free mounting for practical Chevrolet Traverse use, but it is too compact for long skis or very large loads.
4. Perflex Exclusive Hard-Shell Rooftop Cargo Box, 17.7 cu ft
| Item Volume | 500 Liters |
|---|---|
| Weight capacity | 130 lbs |
| Shell Type | Hard |
| Water Resistance Level | Waterproof |
The Perflex Exclusive is a large hard-shell rooftop cargo box intended to add significant luggage capacity to a vehicle with crossbars. It provides 17.7 cu ft (500 L) of storage and carries up to 130 lb, making it suitable for skis, snowboards, duffel bags, and camping gear. The box comes assembled and uses tool-free mounting hardware that fits roof racks and crossbars, while dual-side opening makes loading and unloading from either side of the car easy. Construction uses UV- and impact-resistant ABS with a textured matte finish and a central lock that prevents key removal until secured; the package includes spare keys and straps. In real-world use you can expect straightforward installation, roomy cargo space, and good protection from rain thanks to the waterproof design. Buyers should note the box is large and will add wind resistance and extra height, and some users have reported occasional latch or opening issues that may require customer support or part replacement. The result is a practical, well-featured carrier for extended trips when you need reliable extra storage.
Best for: A balanced, all-round buyer who wants dependable extra cargo space for family trips and outdoor gear on a Chevrolet Traverse and values convenience and build quality over minimalism.
Less Ideal for: Drivers who frequently park in low-clearance garages or who need the lightest possible rooftop solution should consider lower-profile or soft-shell options instead.
- Large 17.7 cu ft (500 L) capacity accommodates skis, snowboards, and bulky luggage
- Dual-side opening for easier loading and unloading from either side of the vehicle
- Waterproof, UV- and impact-resistant ABS shell provides weather protection

Verdict A roomy, secure hard-shell box that adds reliable storage to a Chevrolet Traverse for road trips and outdoor gear, with the usual height and wind-noise compromises of a large carrier.
Choosing the Right Chevrolet Traverse Rooftop Cargo Box: Key Factors to Consider
Mounting Compatibility
Mounting compatibility matters because the cargo box must secure safely to the Traverse s crossbars or roof rails. Confirm whether the box uses universal U-bolts, T-track adapters, or a proprietary clamping system and whether those work with your vehicle s existing crossbar profile.
A mismatched mounting system can increase installation time, require extra adapters, or result in a less secure fit. Look for systems that offer clear torque specs, anti-slip pads, and hardware long enough for thicker crossbars. Ease of access to the mounting points also affects how quickly you can attach or remove the box for seasonal use.
Interior Capacity and Shape
Capacity determines how much you can carry and how gear will fit. Consider both total liters and the usable shape of the box: tapered or narrow fronts can limit bulky items despite a high listed volume.
Think about the typical loads you carry, such as suitcases, skis, or camping gear, and choose a box with a shape and capacity that accommodate those items without excessive force or awkward stacking. Also evaluate how internal contours and latch positions affect usable space so you maximize every liter.
Weight Rating and Roof Load Limits
Every vehicle and roof rack has a load limit; exceeding it can risk damage or unsafe handling. Check the Chevrolet Traverse s roof load rating and total allowable weight for crossbars, then compare that to the cargo box s own empty weight plus the gear you plan to carry.
A lightweight box leaves more of the vehicle s roof load allowance for cargo, while heavier boxes reduce usable capacity. Selecting a box with a favorable strength-to-weight ratio helps you carry more without surpassing limits.
Aerodynamics and Fuel Efficiency
Aerodynamic performance affects wind noise, stability, and fuel consumption on long drives. Lower, narrow profile boxes tend to create less drag and produce less noise at highway speeds than very tall designs.
If you do a lot of highway driving or take long road trips, favor boxes with streamlined profiles and features such as tapered noses. Even small differences in shape can reduce buffeting and make cabin conversations easier during long drives.
Durability and Weather Resistance
A rooftop box is exposed to sun, rain, snow, and road debris, so materials and build quality matter for longevity. Look for impact-resistant shells, robust hinges, and corrosion-resistant hardware to stand up to repeated use and harsh conditions.
Good weather seals and reinforced lids protect contents from moisture and dust. Durable finishes also resist scratches and fading, which helps maintain the box s functional integrity and appearance over years of use.
Ease of Use and Access
Practical features affect daily convenience. Dual-side opening, central locking, and gas-strut assisted lids make loading and unloading simpler and safer, especially when parked on the road shoulder or when one side is blocked.
Consider how easy it is to reach the locks and latches from a step or ladder and whether the box can be opened while mounted. Simpler installation steps and clearer instructions also save time when you need to remove or fit the box seasonally.
FAQ
Will any rooftop cargo box fit my Chevrolet Traverse?
Not every box fits every vehicle. Fit depends on your Traverse s roof crossbars, roof load limit, and the box s mounting hardware. Check the box s mounting compatibility and your vehicle s crossbar profile before buying. Also ensure total loaded weight stays within the vehicle and rack ratings.
How much gear can I typically carry in a rooftop cargo box?
Capacity varies widely, often measured in liters. Typical boxes range from smaller sizes suited for soft goods to large boxes for multiple suitcases or camping gear. Consider both the listed liters and the interior shape to match the types of items you plan to carry.
Does a cargo box affect fuel economy and driving handling?
Yes, a mounted box changes aerodynamics and can increase fuel consumption, especially on highways. Taller or bulkier boxes create more drag and can add wind noise. Choosing a streamlined design and loading sensibly can reduce those effects and help maintain stable handling.
How difficult is roof box installation on a Chevrolet Traverse?
Installation difficulty depends on the box s mounting system and your roof rack setup. Many systems use tool-free clamps or simple bolts, while some require T-track adapters. Two people often make installation safer and faster, and clear instructions or quick-release hardware can simplify the process.
Can I leave items in the box while parked or unattended?
While most hard-shell boxes have locks and weather seals, leaving valuables unattended is not risk-free. Locks deter casual theft and seals protect against moisture, but for high-value items consider additional precautions like storing them out of sight or removing the box when leaving the vehicle for extended periods.
