1. Thule Motion XT L: Best Overall
The Thule Motion XT L is a premium hard-shell cargo box that excels in aerodynamics, security, and ease of use. Based on our research, its dual-side opening and SlideLock system are standout features that make loading and unloading convenient. Owner feedback consistently praises its low wind noise and sturdy construction. The 16-cubic-foot capacity is ideal for families needing extra space for luggage or camping gear.
However, its high cost is a real limitation for budget-conscious buyers. Also, the box is relatively heavy at around 50 pounds, which can make mounting and removal a two-person job. If you rarely need roof storage or only take short trips, a soft-shell carrier may be more practical. Skip this if you are looking for an inexpensive solution.
- Dual-side opening allows loading from either side of the vehicle.
- SlideLock system provides secure locking and easy one-handed operation.
- Aerodynamic design reduces wind noise and drag.
Pros: Excellent build quality and security; Low wind noise even at highway speeds
Cons: Premium price point may not fit all budgets
2. Yakima GrandTour 16: Runner Up
The Yakima GrandTour 16 is a close competitor to the Thule, offering similar capacity and aerodynamic efficiency. Our evaluation shows that its integrated crossbar mounts and SpeedKnobs make installation straightforward without tools. Owner reviews highlight its stability and low wind noise. The interior LED light is a nice touch for loading at night.
Its main drawback is the single-side opening, which can be less convenient when parked on a curb. Also, the price is still on the higher side, though slightly less than the Thule. If you prioritize budget over brand, a less expensive option may serve you well. This is best for those who want top-tier performance but can accept one-side access.
- Aerodynamic shape with integrated crossbar mounts for better fit.
- Tool-free mounting system using SpeedKnobs.
- Interior LED light for visibility in dark conditions.
Pros: Very stable on the roof at high speeds; LED light is a clever convenience feature
Cons: Only opens from one side
3. SportRack Vista XL 18: Best Value
The SportRack Vista XL 18 offers the largest capacity in our lineup at a price that is significantly lower than premium brands. Based on owner feedback, the dual-side opening is a major convenience, and the quick-mount system works well once adjusted. It can hold up to 110 pounds, making it suitable for heavier gear.
However, some owners report that the plastic feels less robust, and the locking mechanism is not as smooth as higher-priced models. Wind noise can be noticeable at highway speeds. If you are a frequent long-distance traveler or demand the highest durability, you may want to invest more. This is ideal for occasional users who want maximum space without breaking the bank.
- Dual-side opening for easy access from either side.
- Quick-mount system with adjustable mounting brackets.
- Large 18-cubic-foot capacity at a reasonable price.
Pros: Very good value for the capacity; Dual-side opening at this price is rare
Cons: Build quality not as premium as Thule or Yakima
4. Rightline Gear Range 2: Best Soft Shell
The Rightline Gear Range 2 is a top-rated soft-shell cargo carrier that offers excellent weather protection and flexibility. Our research indicates that its welded seams and heavy-duty fabric keep contents dry even in heavy rain. It can be strapped directly to the roof if you don’t have crossbars, making it a versatile option. Owner reviews appreciate the easy storage when not in use.
Soft shells have inherent limitations: they are less secure against theft, and items inside can shift during transit, potentially causing wear. Also, wind noise is higher than hard shells. If you carry valuable or fragile items, a hard box is better. This is best for budget travelers who need occasional extra space and don’t mind some wind noise.
- Weatherproof 600D PVC-coated polyester with welded seams.
- Universal fit works with or without crossbars using included straps.
- Reflective strips for increased visibility at night.
Pros: Folds flat for easy storage when not in use; Can be used without crossbars
Cons: Less secure than hard shells; items can shift
5. Rhino-Rack Master Fit RS: Best for Aerodynamics
The Rhino-Rack Master Fit RS is designed for those who prioritize aerodynamics and fuel economy. Our evaluation shows that its teardrop shape significantly reduces wind resistance compared to boxier designs. Owner feedback confirms that it feels stable at high speeds and produces minimal noise. The central locking system adds security.
Its main limitation is the smaller 12.5-cubic-foot capacity, which may not suffice for larger families. Also, the mounting system can be finicky to adjust on some vehicles. If you need maximum storage volume, look elsewhere. This is perfect for solo travelers or couples who want to minimize fuel consumption and wind noise.
- Teardrop shape reduces drag and improves fuel economy.
- Central locking system with key for security.
- Fits most factory and aftermarket crossbars.
Pros: Excellent aerodynamics and fuel efficiency; Strong construction with 110 lb capacity
Cons: Smaller capacity than many competitors
6. Keeper 85000 Cargo Carrier: Budget Pick
The Keeper 85000 is a budget-friendly soft-shell cargo carrier that gets the job done for occasional use. Based on owner feedback, it is easy to install and provides adequate weather resistance for light rain. The included tie-down straps and storage bag add value.
However, several owners report that the material can leak in heavy downpours and that the straps may loosen over long drives. The zipper is also a common failure point. If you plan to use it frequently or in harsh conditions, invest in a higher-quality soft shell. This is best for very occasional users on a tight budget.
- Affordable soft-shell carrier with 14 cu ft capacity.
- Includes 4 heavy-duty tie-down straps and a storage bag.
- Water-resistant PVC-coated nylon material.
Pros: Very low price point; Includes storage bag for compact storage
Cons: Material is less durable than premium soft shells
7. MaxxHaul 50-195-UB: Best Cargo Basket
The MaxxHaul 50-195-UB is a sturdy roof basket that excels at carrying bulky, dirty, or oddly shaped items like coolers, camping gear, or lumber. Our research shows that its steel construction and high weight capacity make it a workhorse. The mesh floor prevents small items from slipping through.
However, it offers no weather protection, so items must be waterproof or bagged. Also, wind noise is significant, and installation can be time-consuming. If you need a weatherproof enclosure, choose a box instead. This is best for outdoor enthusiasts who prioritize versatility and load capacity over aerodynamics and security.
- Heavy-duty steel construction with black powder coat.
- Expanded metal mesh floor prevents small items from falling.
- Universal fit with adjustable mounting clamps.
Pros: Very high load capacity (150 lb); Can carry irregularly shaped items
Cons: No weather protection; contents exposed to elements
Frequently Asked Questions
How do I choose between a hard shell and a soft shell roof cargo carrier?
Hard shell carriers offer better security, aerodynamics, and weather protection but are heavier and more expensive. Soft shells are lighter, fold flat for storage, and cost less, but they are less secure and can produce more wind noise. Choose a hard shell if you travel frequently at highway speeds or carry valuable items. Choose a soft shell for occasional use and budget savings.
Will a roof cargo carrier fit my car?
Most roof cargo carriers require roof crossbars (factory or aftermarket). Check your vehicle’s roof type: bare roof, raised rails, or flush rails. Many carriers come with universal mounting hardware, but always verify compatibility with your specific crossbar system. The carrier’s weight and dimensions must also be within your roof’s load limit (usually found in the owner’s manual).
How much weight can I safely put on my roof?
The maximum roof load is determined by your vehicle’s manufacturer and includes the weight of the carrier plus cargo. Typical limits range from 100 to 165 pounds. Exceeding this can damage your roof or affect handling. Always check your owner’s manual and subtract the carrier’s weight to find the allowable cargo weight.
Do roof cargo carriers affect gas mileage?
Yes, roof cargo carriers increase aerodynamic drag, which reduces fuel economy. Hard shell aerodynamic boxes have less impact than soft shells or baskets. At highway speeds, expect a fuel economy decrease of 10% to 25%. Removing the carrier when not in use helps restore efficiency.
Are roof cargo carriers safe?
Yes, when installed correctly and within load limits. Ensure the carrier is securely attached to crossbars and that the locking mechanism works. Always distribute weight evenly and avoid overloading. Check all straps or clamps before each trip. Some carriers have been tested to meet TUV or other safety standards; look for those.
Our Verdict
Our top pick is the Thule Motion XT L for its outstanding build quality, dual-side opening, and quiet ride. If you want similar performance at a slightly lower price, the Yakima GrandTour 16 is an excellent runner up. For budget-conscious shoppers, the SportRack Vista XL 18 offers great value and capacity.
