1. Thule Motion XT XL: Top Pick
The Thule Motion XT XL is a premium hard-shell cargo box that excels in aerodynamics and ease of use. In our evaluation of specifications and owner feedback, it consistently rates high for security and weather resistance. The dual-side opening makes loading convenient, and the PowerGrip mounting system attaches securely to most factory and aftermarket racks.
However, its weight and cost are significant drawbacks. At 44 lbs empty, it consumes much of your roof load capacity before adding gear. Budget-conscious buyers or those with low weight limits should consider lighter alternatives like the Yakima CBX or a soft cargo carrier.
- Aerodynamic design reduces wind noise and drag
- Central locking system with dual-side opening
- PowerGrip quick-mount system for easy installation
Pros: Excellent build quality and security; Low profile fits in garages
Cons: Premium price point; Heavy at 44 lbs empty
2. Yakima CBX 16: Runner Up
The Yakima CBX 16 is a close competitor to the Thule Motion XT, offering similar capacity and features at a slightly lower weight. Based on owner feedback, the HitchLock system is intuitive, and the box seals well against rain. It fits most crossbars without adapters.
Some users report that the interior shape wastes space compared to the Thule, and the latch mechanism may require breaking in. If you prioritize a lighter box and don’t mind slightly less efficient packing, the CBX is an excellent choice. But for maximum space utilization, the Thule Motion XT may be better.
- HitchLock system for quick attachment and removal
- Aerodynamic shape with integrated crossbar cutouts
- Dual-side opening for easy access from either side
Pros: Sleek design with good aerodynamics; Easy to install and remove
Cons: Interior space is less efficient than Thule Motion XT; Latch can be stiff when new
3. SportRack Vista XL: Best Value
The SportRack Vista XL offers the largest capacity in our comparison at an accessible price point. Owner feedback highlights its easy installation and ability to hold bulky gear like camping equipment. The 110 lb weight limit is higher than many competitors.
However, we found that the build quality does not match Thule or Yakima. The locking mechanism feels flimsy, and some owners report water ingress in heavy rain. Wind noise is also more noticeable. If you need maximum space on a budget and can tolerate some compromises, this is a solid option. But for frequent long-distance travel, consider spending more for a premium box.
- Large 18 cu ft capacity for bulky items
- Dual-side opening with quick-release mounting
- Fits most factory and aftermarket crossbars
Pros: Generous capacity for the price; Relatively lightweight for its size
Cons: Latch and lock feel less robust than premium brands; Higher wind noise at highway speeds
4. Rightline Gear Range 4: Best Soft Carrier
The Rightline Gear Range 4 is a soft cargo carrier that offers a lightweight and low-cost solution for occasional use. Owner feedback praises its waterproof construction and ease of folding. It fits most roof racks with crossbars and can hold up to 100 lbs.
However, soft carriers have inherent drawbacks. They are less aerodynamic, causing wind noise and potential drag. The straps can loosen over time, requiring periodic checks. Security is minimal as the bag can be cut. This product is best for budget-minded travelers who need temporary extra space and can monitor their load during trips. Not recommended for long highway journeys or valuable gear.
- Waterproof PVC-coated fabric with welded seams
- Four heavy-duty straps with cam buckles for secure mounting
- Folds flat for storage when not in use
Pros: Ultra-lightweight and easy to store; Affordable compared to hard shells
Cons: Not as secure against theft; Can flap at high speeds if not tightened properly
5. Yakima LoadWarrior: Best Basket
The Yakima LoadWarrior is a classic roof basket that excels in carrying bulky, irregular items that won’t fit in a box. Owner feedback highlights its durability and ability to hold up to 150 lbs. The steel construction withstands heavy use and the powder coat resists rust.
But it is not weatherproof, so cargo must be secured and covered. The basket itself is heavy and adds wind noise even with the fairing. Installation requires some assembly and may not fit all crossbars without adapters. This is ideal for off-roaders or campers who need to haul firewood, coolers, or gear boxes. Not suitable for those seeking weather protection or easy access.
- Steel construction with black powder-coat finish
- Expandable with optional extension (sold separately)
- Includes wind fairing to reduce noise
Pros: Very durable and rugged for heavy/bulky items; Can carry odd-shaped loads like coolers or propane tanks
Cons: No weather protection; items must be bagged or tied down; Installation can be tricky with some crossbars
6. Thule Sidekick: Compact Choice
The Thule Sidekick is a soft bag designed for small loads and compact cars. Based on owner feedback, it installs quickly and folds down for storage. The waterproof roll-top keeps rain out, and the bag stays secure at moderate speeds.
But its 8 cu ft capacity and 50 lb limit are restrictive for most families. The strap system is less robust than the Rightline Gear and may require retightening. This product is best for solo travelers or couples with minimal gear who need occasional extra space. For larger families or longer trips, a hard shell box or larger soft bag would be more practical.
- Compact size fits small cars and tight spaces
- Easy to mount with integrated straps
- Waterproof roll-top closure
Pros: Lightweight and easy to handle; Good for occasional use on small vehicles
Cons: Small capacity limits usefulness; Straps can loosen over time
7. Curt 18110 Roof Cargo Basket: Budget Basket
The Curt 18110 is an affordable roof basket for those on a tight budget. Owner feedback indicates it holds a lot of gear and is sturdy enough for occasional use. The tie-down hooks are convenient, and the basket fits most crossbars.
However, we found the build quality lacking compared to Yakima. The powder coat is prone to chipping, and without a wind fairing, wind noise is significant. Installation instructions are sparse. This basket is best for users who need a cheap, temporary solution and don’t mind some noise and cosmetic wear. For long-term use, investing in a Yakima LoadWarrior or similar is recommended.
- Steel basket with black powder coat
- Expands with extension kit (sold separately)
- Includes tie-down hooks and mounting hardware
Pros: Low cost for a large basket; Holds heavy loads up to 150 lbs
Cons: Paint may chip over time; No wind fairing included; noise can be loud
Frequently Asked Questions
What is the weight limit for roof cargo carriers?
Weight limits vary by carrier and vehicle roof rack. Most hard-shell boxes have a limit of 75-110 lbs, while baskets can hold up to 150 lbs. Always check your vehicle’s dynamic roof load rating (typically 165 lbs for cars) and subtract the carrier’s weight. Exceeding limits can damage your roof or cause accidents.
Do roof cargo boxes affect gas mileage?
Yes, roof cargo carriers increase wind resistance and reduce fuel economy. Hard-shell boxes are more aerodynamic than baskets or soft bags, but all cause some drag. Expect a 10-25% decrease in MPG at highway speeds. Removing the carrier when not in use helps restore efficiency.
Can I use a roof cargo carrier with a sunroof?
Yes, most carriers can be used with sunroofs as long as the crossbars are positioned correctly. However, the carrier may block the sunroof’s view or opening. Check the carrier’s dimensions and your roof layout before purchasing. Some slim profiles like the Thule Motion XT minimize obstruction.
How do I secure items in a roof basket?
Use ratchet straps or bungee cords to tie down items to the basket’s rails. For weather protection, wrap gear in a tarp or use a waterproof cargo bag. Ensure nothing protrudes beyond the basket’s edges. Regularly check tension during trips to prevent shifting.
Are soft cargo carriers safe for long trips?
Soft carriers can be safe if properly installed and monitored. They are more prone to loosening and flapping at high speeds, so check straps at every stop. Avoid overloading and ensure the carrier does not obstruct rear view. For long trips, hard-shell boxes offer better security and aerodynamics.
