1. Thule Motion XT L: Best Overall
The Thule Motion XT L stands out in our research for its aerodynamic efficiency and durable construction. Owner feedback consistently highlights its quiet operation and secure mounting, even at highway speeds. The dual-side opening and spring-loaded lid make loading and unloading convenient, while the Power-Click system ensures a quick, tool-free installation. Based on the spec sheet, it offers excellent weather protection with a tested locking mechanism.
However, the high cost may deter some buyers, and the 16 cubic foot capacity is modest compared to larger boxes. This topper is ideal for those who prioritize aerodynamics and premium features, but if you need maximum volume for bulky gear, consider a larger model. Drivers with tall vehicles should also check garage clearance before purchase.
- Aerodynamic design reduces wind noise and fuel consumption.
- Dual-side opening with quick-mount system for easy access.
- Integrated Power-Click mounting fits most factory crossbars.
Pros: Exceptional build quality and weather sealing.; Low profile maintains vehicle aesthetics.
Cons: Premium price point may not suit budget-conscious buyers.
2. Yakima SkyBox 21 Carbonite: Top Rated
The Yakima SkyBox 21 Carbonite earns high marks from owners for its generous capacity and sturdy construction. Our evaluation of the spec sheet shows a strong ABS shell with a textured finish that hides scratches well. The SKS lock system provides added security, and the dual-side opening with gas struts makes loading easy. Many users note that it fits skis and snowboards easily, making it a favorite for winter sports enthusiasts.
On the downside, its weight and height can increase wind resistance, leading to a modest drop in fuel economy. This topper is best for families or adventurers who need extra space and value durability over weight savings. If you have a smaller SUV or frequently park in low garages, measure carefully as the SkyBox sits higher than some low-profile models.
- Large 21 cu ft capacity fits extra luggage and gear.
- SKS lock system secures the box to crossbars and lid.
- Dual-side opening with gas struts for easy lifting.
Pros: Spacious interior accommodates bulky items.; Durable ABS shell resists impacts and UV rays.
Cons: Heavier than some competitors, affecting fuel economy slightly.
3. SportRack Vista XL Rear Opening Cargo Box: Best Value
The SportRack Vista XL is a budget-friendly option that still delivers reliable performance. According to owner feedback, it seals well against rain and dust, and the quick-mount system is straightforward. The 15 cu ft capacity is adequate for a family weekend trip, and the lightweight design makes it easy to handle alone. We found the build quality to be good for the price, with a durable ABS shell.
However, the rear-only opening can be a drawback when the box is fully loaded, and some users report the locking mechanism feels less solid than premium brands. This topper is best for budget-conscious buyers or those who only need occasional extra space. If you frequently access gear from the side, consider a dual-opening model.
- Affordable price point with solid performance.
- Rear opening design allows easy access from the back.
- Quick-mount system with adjustable straps fits most crossbars.
Pros: Excellent value for the price.; Lightweight and easy to install and remove.
Cons: Rear opening only may be inconvenient for side access.
4. INNO Wedge 660 Cargo Box: Clean Design
The INNO Wedge 660 is designed for style-conscious drivers who want a low-profile cargo box. Our research indicates it performs well in wind tunnel tests, producing minimal noise and drag. The dual-side opening and padded clamps make installation easy to use. Owner reviews praise its low-profile appearance and how it blends with vehicle lines.
However, durability concerns appear in some long-term feedback, with latches occasionally needing adjustment. The interior finish is also less plush than higher-end boxes. This topper is best for those who prioritize aesthetics and moderate use. If you need a rugged box for frequent heavy loads, consider a more sturdy option.
- Compact wedge shape reduces drag and noise.
- Dual-side opening with ergonomic handles.
- Tool-free mounting system with padded clamps.
Pros: Attractive design complements modern SUVs.; Quiet on the highway compared to boxier models.
Cons: Some owners report latch alignment issues over time.
5. Rola 59004 Vortex Cargo Box: Compact Fit
The Rola Vortex is a compact cargo box ideal for smaller SUVs or those who only need occasional extra space. Based on owner feedback, it mounts securely and doesn’t significantly impact fuel economy. The 11 cu ft capacity is enough for a couple of suitcases or camping gear for two. Its lightweight design makes it one of the easiest to install and remove.
However, the small size is a limitation for longer family vacations, and some users note the plastic feels less premium. The rear-only opening can also be a hassle. This topper is best for city dwellers or those with limited roof space. If you need to carry skis or bulky items, look for a larger model.
- Compact size fits smaller SUVs and crossovers.
- Lightweight at 28 lbs for easy handling.
- Aerodynamic shape reduces wind resistance.
Pros: Very affordable and easy to store when not in use.; Good for daily commutes or small families.
Cons: Limited capacity may not suit longer trips.
6. Goplus 15 Cubic Feet Roof Mount Cargo Carrier: Budget Pick
The Goplus cargo carrier is the most budget-friendly option in our guide. It offers a respectable 15 cu ft capacity at a fraction of the cost of premium boxes. Owner feedback indicates it works fine for occasional use, especially in dry conditions. The installation is straightforward with included straps and clamps.
However, durability concerns are significant: many users report cracks after a few uses, and the lock is basic. Water leakage is common in heavy rain. This topper is only suitable for those who need a temporary solution on a tight budget and don’t mind replacing it after a season. For regular use, investing in a higher-quality box is recommended.
- Very low price point for budget-conscious shoppers.
- 15 cu ft capacity offers decent space.
- Includes mounting hardware and lock for basic security.
Pros: Extremely affordable.; Lightweight and easy to handle.
Cons: Build quality and weather sealing are below average.
7. Yakima GrandTour 16: Premium Alternative
The Yakima GrandTour 16 is a premium box that competes directly with the Thule Motion XT. It offers similar features like dual-side opening and integrated mounting. Owner reviews highlight its quiet ride and secure fit. The build quality is excellent, with a tough ABS shell and reliable locks.
However, it is priced higher than many 16 cu ft boxes, making it a weaker value. Some users also note that the interior space is slightly less usable due to the curved shape. This topper is best for those who want a premium brand and are willing to pay extra for the Yakima name. If you’re focused on value, the SportRack or Rola offer similar capacity for less.
- Dual-side opening with gas struts for easy access.
- Slim design with integrated mounting system.
- Lockable lid and crossbar attachment.
Pros: Good aerodynamics reduce noise.; Sturdy construction with quality materials.
Cons: Expensive relative to its capacity.
Frequently Asked Questions
Will a cargo topper fit any SUV roof rack?
Most cargo toppers are designed to fit a broad selection of factory and aftermarket crossbars, but it’s important to check compatibility. The mounting system (e.g., U-bolts, clamps, or integrated brackets) must match your crossbar shape and spacing. Always measure your roof rack’s width and distance between bars before purchasing.
How much does a cargo topper affect fuel economy?
Based on owner reports and manufacturer data, a cargo topper can reduce fuel economy by 10-25% at highway speeds, depending on its size, shape, and how you drive. Aerodynamic models like the Thule Motion XT minimize the impact, while larger, boxier boxes cause more drag. Removing the box when not in use helps save fuel.
Are cargo toppers waterproof?
Most cargo toppers are designed to be weather-resistant, but few are completely waterproof. Premium models like Thule and Yakima have excellent seals that keep out rain and snow during normal conditions. However, heavy rain or car washes can sometimes cause minor leaks. It’s wise to pack items in waterproof bags as a precaution.
How do I secure a cargo topper to prevent theft?
All cargo toppers come with locks that secure the lid and often the box to the crossbars. Use the included keys and ensure the lock is properly engaged. For extra security, some owners use cable locks or store the box inside when not in use. Thule and Yakima have integrated locking systems that are quite secure.
Can I install a cargo topper by myself?
Yes, most cargo toppers are designed for solo installation, especially lighter models. The process typically involves lifting the box onto the roof rack and tightening clamps or straps. Some heavier boxes (over 50 lbs) may require assistance. Always follow the manufacturer’s instructions and ensure the box is securely attached before driving.
Our Verdict
After researching and comparing the options, the Thule Motion XT L is our top pick for its blend of aerodynamics, build quality, and ease of use. For those who need more space at a lower price, the Yakima SkyBox 21 Carbonite is an excellent runner-up with its generous capacity and durable construction.
