1. Thule Motion XT L: Best Overall
The Thule Motion XT L is a top contender for those seeking a premium roof cargo box. In our evaluation, its aerodynamic shape and dual-side opening stand out, making loading and unloading convenient. Based on owner feedback, the PowerGrip mounting system provides a secure, rattle-free fit on plenty of crossbars. The box is well-constructed with durable materials that resist cracking and fading over time.
However, the high cost is a significant barrier. If you rarely use a roof carrier or need a budget option, consider alternatives. The Motion XT L is best for frequent travelers who value aerodynamics, security, and ease of use, and are willing to invest in a long-term solution.
- Aerodynamic design reduces wind noise and drag, improving fuel efficiency
- Dual-side opening with integrated mounting system for easy loading and installation
- PowerGrip quick-mount system ensures secure fit on most factory and aftermarket crossbars
Pros: Excellent build quality and durability; Low profile and compact design
Cons: Premium price point may not suit budget-conscious buyers
2. Yakima SkyBox Carbonite 21: Best Value
The Yakima SkyBox Carbonite 21 offers a compelling balance of capacity, weight, and price. In our research, its Carbonite material provides good durability without the heft of fiberglass. The QuickDraw mounting system is straightforward, and owner feedback highlights the ease of installation. The dual-side opening is a practical feature for accessing gear from either side.
One limitation is that some users find the latch stiff, requiring extra effort to close securely. If you need a larger capacity or smoother latching, the Thule Motion XT might be better. The SkyBox Carbonite 21 is ideal for cost-conscious buyers who want a reliable, lightweight cargo box for occasional road trips.
- Carbonite material is lightweight yet impact-resistant
- Tool-free QuickDraw mounting system for fast installation and removal
- Dual-side opening with integrated handle and lock
Pros: Great value for the capacity and features; Lightweight design is easy to handle
Cons: Latch mechanism reported to be stiff by some users
3. SportRack Vista XL Rear Opening Cargo Box: Best Budget
The SportRack Vista XL is a budget-friendly hard-shell cargo box that offers decent value. We found its rear opening design unique and practical for accessing gear from the back of the vehicle. Based on owner feedback, the aerodynamic shape helps keep wind noise manageable. The included mounting hardware fits most crossbars, though some users report a slightly fiddly installation.
However, the weight capacity is limited to 75 lb, and some reviews mention latch issues after extended use. If you need to carry heavy items or want a more sturdy latch, consider spending more on a Yakima or Thule. The Vista XL is best for light, occasional use and tight budgets.
- Rear opening design allows access without reaching over the roof
- Aerodynamic shape reduces wind resistance
- Includes mounting hardware for most crossbars
Pros: Very affordable for a hard-shell cargo box; Rear opening is convenient for shorter users
Cons: Lower weight capacity compared to premium boxes; Some reports of latch durability issues over time
4. Yakima LoadWarrior Roof Basket: Best Roof Basket
The Yakima LoadWarrior is a rugged roof basket for those who need to haul bulky items like camping gear, kayak paddles, or luggage without a box. In our evaluation, its steel construction and high 150 lb capacity make it among the most durable options. Based on owner feedback, the universal mounting system works with most crossbars, and the basket can be expanded with Yakima accessories.
The main drawback is wind noise, which can be loud on the highway. Also, items are exposed to the elements unless you add a cargo bag. If you prioritize quietness and weather protection, a cargo box is better. The LoadWarrior is ideal for outdoor enthusiasts who need an open basket for odd-shaped gear.
- Heavy-duty steel construction with black powder coat finish for durability
- Expandable with optional accessories like extension and cargo net
- Universal fit on most round, square, and factory crossbars
Pros: Very durable and can carry bulky, irregular loads; High weight capacity for heavy gear
Cons: Significant wind noise at highway speeds; Requires a separate weatherproof bag for dry storage
5. Thule Force XT L: Solid All-Rounder
The Thule Force XT L is a well-rounded cargo box that combines ease of use with reliable performance. Our research shows its quick-mount system with torque indicator simplifies installation, and the dual-side opening with struts allows smooth access. Owner feedback highlights the durable ABS shell that resists fading and cracking. The 16 cu ft capacity is suitable for most families.
Some users note that the latch requires careful alignment to close securely, which can be frustrating. If you prefer a simpler latch, the Yakima SkyBox may be easier. The Force XT L is a solid choice for those who want a dependable, easy to use cargo box without the premium price of the Motion XT.
- Quick-mount system with integrated torque indicator for secure installation
- Dual-side opening with lid struts for easy access
- Durable ABS plastic shell with UV protection
Pros: Excellent ease of installation and removal; Good balance of capacity and aerodynamics
Cons: Latch design can be tricky to close tightly
6. Rightline Gear SUV Tents Roof Top Carrier: Best Soft Bag
The Rightline Gear SUV Tents Roof Top Carrier is a soft-sided cargo bag that offers a low-cost, flexible solution. Based on our research, its waterproof fabric and roll-top closure keep gear dry, and the strap-based mounting system works on vehicles without crossbars. Owner feedback appreciates the ease of installation and foldable design for storage.
However, soft bags are less secure and aerodynamic than hard boxes. At highway speeds, the bag can flap and cause wind noise, and durability is lower over time. If you need long-term reliability or carry valuable items, a hard shell is better. The Rightline bag is best for occasional trips where budget and portability are priorities.
- Waterproof construction with welded seams and roll-top closure
- Mounts to roof without crossbars using integrated straps and door hooks
- Folds flat for storage when not in use
Pros: No crossbars required, fits most vehicles with rain gutters or door frames; Affordable and easy to store
Cons: Not as secure as hard-shell boxes; potential for flapping at high speeds; Limited durability compared to hard shells
7. INNO Roof Cargo Box Wedge 660: Compact & Efficient
The INNO Wedge 660 is a compact roof box designed for smaller vehicles. In our evaluation, its wedge shape improves aerodynamics and fits cars with low roof rails. Based on owner feedback, the installation is straightforward with rubber pads that protect the crossbars. The rear opening is convenient for accessing items from the back.
However, the 11 cu ft capacity and 75 lb limit are restrictive for longer trips. Some users have noted the latch can be misaligned, requiring adjustment. If you have a larger vehicle or need more space, consider the Yakima SkyBox. The INNO Wedge 660 is suitable for small cars and light packing.
- Compact wedge shape fits smaller vehicles and reduces wind drag
- Lightweight ABS construction with rear opening for easy access
- Universal mounting system with rubber compression pads
Pros: Good for small cars with limited roof space; Relatively affordable compared to larger boxes
Cons: Small capacity may not suit families; Some reports of latch alignment issues
Frequently Asked Questions
What is the best type of roof carrier for a car?
The best type depends on your needs. Hard-shell cargo boxes offer weatherproofing, security, and aerodynamics, ideal for frequent travelers. Roof baskets are great for bulky, irregular items but require a separate bag for dry storage. Soft bags are budget-friendly and foldable but less durable and secure. We recommend hard-shell boxes for most users.
How do I choose the right size roof carrier?
Measure your vehicle’s roof space and check crossbar spread. Consider the volume of gear you typically carry. For families, 16-21 cu ft is common. Also check weight capacity, which includes the box and contents. Ensure your vehicle’s roof dynamic load limit (usually 100-165 lb) isn’t exceeded.
Will a roof carrier affect my fuel economy?
Yes, any roof carrier increases wind resistance and reduces fuel economy, typically by 10-25% at highway speeds. Aerodynamic cargo boxes like the Thule Motion XT minimize drag. Removing the carrier when not in use helps restore efficiency.
Can I install a roof carrier on any car?
Most cars with roof rails or crossbars can accommodate a roof carrier. Some soft bags mount without crossbars using door hooks. Always check compatibility with your vehicle’s roof type and weight limits. Convertibles, sunroofs, or very small cars may not support a carrier.
How do I secure my roof carrier to prevent theft?
Most hard-shell boxes come with integrated locks. Always lock the box and, if possible, use a locking cable to secure it to the crossbars. Remove the carrier when parked for extended periods. Some carriers have replacement lock cores for added security.
Our Verdict
After researching and comparing, the Thule Motion XT L earns our top pick for its superior aerodynamics, build quality, and ease of use, making it the best overall roof carrier. For a more affordable option that still offers excellent performance, the Yakima SkyBox Carbonite 21 is our runner-up, providing great value and reliability.
