More Details on Our Top Picks
Thule Pulse 2 L Roof Mounted Cargo Box, 16 Cubic Ft
The Thule Pulse 2 L stands out as the best overall choice due to its balanced combination of capacity, ease of installation, and weather resistance. Its 16 cubic feet of space comfortably accommodates luggage, skis, or snowboards, making it ideal for diverse trips. Compared with the Thule Motion 3, which offers a sleeker, more aerodynamic profile, the Pulse 2 L prioritizes practicality and durability, though its streamlined shape may not suit all vehicle styles. Its tool-free, torque-indicator system simplifies installation and ensures secure mounting, while ASA-ABS plastic construction offers excellent weather resistance. However, its 75 kg load limit could be restrictive for very heavy gear, and its shape might not fit some vehicles perfectly. Overall, this model is perfect for users seeking a robust, straightforward cargo solution that can handle various outdoor adventures without fuss.
Pros:- Easy to install with a tool-free system and torque indicator
- Provides ample cargo space for diverse gear
- Weather-resistant and durable construction
Cons:- Limited to 75 kg load capacity, restricting very heavy gear
- Streamlined shape may not fit all vehicle types
Best for: Active families needing reliable, weatherproof storage for skiing gear, luggage, or sports equipment.
Not ideal for: Users requiring ultra-lightweight or highly aerodynamic designs for fuel efficiency, or those with very heavy cargo needs exceeding 75 kg.
- Capacity:16 Cubic Feet
- Load Capacity:75 kg
- Material:ASA-ABS plastic
- Access:Dual-side opening
- Dimensions:450 liters
- Installation:Tool-free with torque indicator
Our verdict“A versatile, durable choice suited for active families who prioritize capacity and weather resistance over sleek design.”
Thule Motion 3 Rooftop Cargo Box
The Thule Motion 3 excels in combining spacious storage with an aerodynamic silhouette, making it a top pick for drivers looking to reduce drag and improve fuel efficiency. Its generous dimensions of 81″L x 38″W x 18″H provide ample space, and the quick-mount system simplifies installation. Compared to the Thule Pulse 2 L, the Motion 3 prioritizes sleekness and efficiency, though it may lack the same level of ruggedness in extremely harsh weather. Its integrated locks and secure closure keep gear safe, while the smooth, aerodynamic shape minimizes wind resistance. However, the absence of detailed accessory compatibility and limited price transparency can be drawbacks for some buyers. This model is ideal for those who want a stylish, efficient carrier that doesn’t compromise on capacity.
Pros:- Aerodynamic design reduces drag and boosts fuel efficiency
- Easy to mount with quick-mount system and torque indicator
- Secure locking system ensures lid stays closed
Cons:- Limited details on accessory compatibility
- Price information not clearly available
Best for: Travelers seeking a modern, aerodynamic carrier that boosts fuel efficiency and offers secure, easy access.
Not ideal for: Car owners with budget constraints or those needing a more rugged, heavy-duty cargo box for extreme weather conditions.
- Dimensions:81″L x 38″W x 18″H
- Material:Not specified
- Mounting System:Quick-mount
- Locking System:Integrated locks
- Warranty:Limited Lifetime
Our verdict“This pick makes the most sense for drivers prioritizing sleek design and reduced wind resistance over maximum capacity or ruggedness.”
Thule Force 3 L Cargo Box
The Thule Force 3 L offers a sleek, practical design tailored for everyday use. Its quick, secure mounting system paired with the SlideLock safety feature makes installation and access straightforward. Its 3-liter capacity, however, is quite limited compared to larger options like the Thule Pulse 2 L, making it better suited for smaller gear or supplemental storage. The durable and stylish exterior ensures it can withstand daily wear, and dual-side access adds convenience. Compared to the more spacious Motion 3, the Force 3 L sacrifices capacity for a more compact, lightweight profile. The main tradeoff is its limited volume, which might not meet the needs of larger families or those packing bulky gear. It’s perfect for city commuters or occasional travelers who need a dependable, low-profile cargo box.
Pros:- Durable, stylish design suitable for daily use
- Easy and secure mounting with visual indicators
- Provides convenient access from both sides
Cons:- Limited capacity may not suit larger cargo needs
- Not ideal for bulky or heavy gear
Best for: Urban drivers or individuals needing a compact, easy-to-use cargo solution for daily errands or light trips.
Not ideal for: Large families or outdoor enthusiasts with bulky gear requiring extensive storage capacity.
- Capacity:3 liters
- Mounting System:Quick and secure with indicator
- Locking System:SlideLock
- Dimensions:Not specified
Our verdict“Best suited for users who need a reliable, stylish, and compact cargo solution for everyday use.”
TUFFIOM 13.4 cu.ft. Rooftop Cargo Box
The TUFFIOM 13.4 cu.ft. offers a solid balance of waterproof protection and capacity at a competitive price point. Its 13.4 cubic feet of space is ample for typical travel gear, and the ABS construction ensures belongings stay dry and secure in bad weather. Its dual-side opening simplifies access, especially during tight parking situations. Comparing it with the GarveeTech, which has slightly more capacity, the TUFFIOM’s advantage lies in its proven waterproofing and straightforward design. The main tradeoff is its 3-year warranty, shorter than premium options like Thule, and the weight capacity of 150 lbs might limit very heavy gear. This model is well-suited for users seeking reliable weatherproof storage without the premium price tag.
Pros:- Waterproof and durable ABS construction
- Dual-side opening for easy access
- Locks with keys for security
Cons:- Limited warranty period of three years
- Capacity might be insufficient for very bulky loads
Best for: Travelers needing a waterproof, secure storage option for moderate loads on SUV or car roof racks.
Not ideal for: Heavy-duty users or those requiring extensive warranty coverage for long-term use.
- Capacity:13.4 cubic feet
- Dimensions:61″ L x 27.6″ W x 13.8″ H
- Material:ABS
- Max Load Capacity:150 lbs
- Locking System:Yes, with keys
- Warranty:3 years
Our verdict“A dependable waterproof cargo box ideal for moderate trips and weather protection without high-end features.”
GarveeTech Rooftop Cargo Box Carrier
The GarveeTech Cargo Box stands out with its generous 12 cubic feet capacity and high weight limit of 165 lbs, making it suitable for larger loads and heavier gear. Its dual-side opening enhances convenience, especially for quick access during busy trips. Compared to the TUFFIOM, it offers a slightly lower overall capacity but compensates with a higher weight limit and a more universal mounting system, compatible with most roof racks. The one-year warranty, however, is shorter than premium brands, which might concern long-term durability. Its waterproof ABS shell protects gear in diverse weather conditions, though potential buyers should verify roof rack compatibility beforehand. This model suits those who prioritize large capacity and broad fit compatibility for frequent or heavy-duty trips.
Pros:- Large 12 cubic feet capacity increases cargo space
- High weight limit of 165 lbs for heavy gear
- Dual-side opening for easy access
Cons:- May require verification for roof rack compatibility
- Limited warranty period of one year
Best for: Frequent travelers or outdoor enthusiasts needing a high-capacity, waterproof carrier compatible with most vehicles.
Not ideal for: Casual users or those seeking long-term warranty support, as it has only a one-year warranty period.
- Capacity:12 cubic feet
- Weight Capacity:165 lbs
- Dimensions:54.3 in L x 31.5 in W x 13.4 in H
- Material:ABS
- Opening:Dual-sided
- Warranty:1 year
Our verdict“A high-capacity, waterproof cargo carrier best suited for users with significant gear needs and universal fit requirements.”
Yakima DeepSpace Hard Shell Cargo Box, Travel and Storage Gear Case, Black
The Yakima DeepSpace Cargo Box stands out for offering a generous 10 cubic feet of storage, making it an excellent choice for those seeking a balanced combination of capacity and security. Its wide opening simplifies loading, and the interior tie-down points with SKS lock enhance theft deterrence, especially compared to the thinner-walled Thule Pulse 2. While it requires crossbars (not included), its durable textured ABS construction keeps weight manageable without sacrificing toughness. Compared to larger options like the Hard Shell Roof Top Carrier, it’s more compact but still spacious enough for most gear. The installation process is straightforward with universal hardware, but the need for crossbars might add an extra step for some users. This model makes the most sense for drivers needing a secure, reliable cargo box that’s easy to install on a variety of vehicles.
Pros:- Spacious 10 cubic feet capacity
- Easy to install with universal mounting hardware
- Secure with interior tie-down points and SKS lock
- Durable, lightweight textured ABS material
Cons:- Requires vehicle crossbars not included
- Not compatible with the EXO system
Best for: Families needing secure, medium-capacity storage with easy installation on standard crossbar systems
Not ideal for: Solo travelers with roof racks incompatible with universal mounting hardware or those seeking maximum capacity
- Capacity:10 cubic feet
- Load rating:100 pounds
- Material:Textured ABS
- Installation:Requires crossbars (not included)
Our verdict“This cargo box is best suited for users who prioritize security and ease of setup without needing maximum volume.”
Hard Shell Roof Cargo Box, 26 Cu Ft Extra Large Rooftop Carrier with Dual-Side Opening, Tool-Free Install, Secure Lock System
This 26 cubic feet cargo box is ideal for large families or adventure seekers needing ample space for gear, surpassing the 18 cu ft options like the Yakima SkyBox NX 18 XLG. Its impact-resistant ABS+PC composite ensures durability in tough weather, while dual-side opening allows quick access from either side—an advantage over rear-opening models like the SportRack Vista XL. The tool-free installation simplifies setup, but its weight might be challenging for solo handling, especially compared to lighter models like the Yakima DeepSpace. Its 150 lbs load capacity makes it suitable for heavy gear, but the large size demands ample roof space and proper roof rack compatibility. Overall, this box makes the most sense for users needing maximum storage without sacrificing security or convenience.
Pros:- Huge 26 cubic feet capacity
- Impact-resistant, weatherproof ABS+PC material
- Dual-side opening for easy access
- Tool-free installation
Cons:- Heavy to handle alone
- Requires compatible roof racks for installation
Best for: Large families or outdoor enthusiasts with large roof racks seeking maximum storage capacity
Not ideal for: Casual drivers with limited roof rack space or those who prefer lightweight options
- Capacity:26 Cu Ft
- Load Capacity:150 lbs
- Material:ABS+PC composite
- Opening:Dual-side
Our verdict“This model is best for those who prioritize maximum volume and straightforward setup over ease of handling.”
Yakima SkyBox NX 18 XLG Rooftop Cargo Carrier, 18 Cu Ft, SKS Lock, Black
The Yakima SkyBox NX 18 XLG offers 18 cubic feet of secure storage, striking a balance between size and security for active families or snowboarders, with the added benefit of dual-sided access similar to the larger 26 cu ft options. Its durable nano-texture finish provides a sleek appearance and resistance to scratches, outperforming less refined finishes like the Garvee Carrier. The full metal locking handle and SKS system enhance security, but the box’s weight can make installation tricky for one person, especially when compared to lighter models like the DeepSpace. Its capacity suits up to four campers or snowboards up to 195cm, making it versatile for adventure gear. This makes it an ideal choice for those needing dependable security and style without the bulk of larger carriers.
Pros:- Generous 18 cubic feet of storage
- Dual-sided access for convenience
- Secure SKS locking system
- Sleek nano-texture finish for durability
Cons:- Heavy and potentially difficult to install alone
- Limited color options
Best for: Active outdoor enthusiasts needing secure, mid-sized storage for gear and sports equipment
Not ideal for: Drivers with limited roof rack compatibility or who prioritize maximum volume over security features
- Capacity:18 Cu Ft
- Fits Snowboards/Ski Length:up to 195cm
- Locking System:SKS Locks
- Color:Black
- Model Number:8007370
- Manufacturer Warranty:Limited-lifetime warranty
Our verdict“This cargo box suits users seeking a secure, stylish, mid-capacity carrier for active adventures.”
Garvee Rooftop Cargo Box Carrier, Dual-Side Opening Luggage Storage
The Garvee Cargo Box provides 12 cubic feet of weatherproof storage, making it a reliable choice for those concerned with protecting gear from the elements, especially compared to the larger but less weatherproof SportRack Vista XL. Its high-quality ABS construction resists UV damage and water, and the dual-side opening simplifies access during busy trips. While its 165 lbs max load is generous, verifying roof rack compatibility is important, and its installation may not be as straightforward as tool-free models like the Hard Shell Roof Carrier. Its sleek aerodynamic design also helps reduce fuel consumption and noise, which can be advantageous for longer trips. This box is particularly well-suited for drivers who need dependable, weather-resistant storage without the bulk of larger carriers.
Pros:- Durable, weather-resistant ABS construction
- Large 12 cubic feet storage capacity
- Dual-sided opening for easy access
- Aerodynamic design reduces noise and fuel consumption
Cons:- Requires roof rack compatibility check
- Limited to vehicles with roof racks
Best for: Road trippers in need of durable, waterproof storage with minimal impact on fuel efficiency
Not ideal for: Those seeking maximum capacity or easy installation without verifying roof rack compatibility
- Material:ABS plastic
- Capacity:12 cubic feet (340L)
- Dimensions:54.3″L x 31.5″W x 13.4″H
- Max Load:165 lbs
- Opening:Dual-sided
- Warranty:1 year
Our verdict“This cargo box is best for drivers needing waterproof protection and aerodynamic efficiency for moderate gear loads.”
SportRack Vista XL Rear Opening Cargo Box
The SportRack Vista XL offers 18 cubic feet of capacity in a UV-resistant, durable design, making it a reliable choice for budget-conscious users who prioritize rear access, unlike the dual-sided options like the Yakima SkyBox NX. Its secure locking system and tool-free mounting hardware simplify installation, although its weight can pose challenges for solo handling, especially compared to lighter models like the Yakima DeepSpace. It fits various rack sizes within its range, but users should verify compatibility beforehand. While it may not feature the sleek finish or advanced security of premium options, it provides solid value for those looking for a straightforward, rear-opening cargo solution at a lower price point.
Pros:- Large 18 cubic feet capacity
- UV-resistant, durable construction
- Rear opening for easy access
- Tool-free mounting hardware
Cons:- Heavy to handle alone
- Limited color options
Best for: Budget-conscious families or casual travelers needing rear access and decent capacity
Not ideal for: Solo travelers with limited strength or those seeking dual-side access for convenience
- Capacity:18 cubic feet
- Material:UV-resistant ABS
- Dimensions:63 x 38 x 19 inches
- Max Weight Capacity:100 pounds
- Opening:Rear
Our verdict“This rear-opening cargo box is ideal for budget-minded users who need reliable, easy-to-install storage with rear access.”
Hard Shell Roof Top Cargo Carrier Waterproof Travel Luggage Box
This cargo box stands out for its sturdy ABS plastic construction, offering solid weather protection at a price point more accessible than premium brands like Thule. Its easy, tool-free installation makes it ideal for those who want quick setup without sacrificing durability. The secure lock adds peace of mind, especially during long outdoor trips. Compared with the Auto Dynasty model, it’s slightly less spacious but more affordable and simple to mount. Its main tradeoff lies in its limited color options and the need for additional mounting accessories on some vehicles, which could complicate installation. This pick makes the most sense for budget-conscious drivers seeking reliable weatherproof cargo space without complex features.
Pros:- Durable, weather-resistant ABS plastic construction
- Easy to install without tools, saving time
- Secure lock enhances safety during travel
- Supports up to 110 lbs, accommodating significant cargo
Cons:- Fits only vehicles with cross bars, limiting versatility
- Limited color choices may not match all vehicle aesthetics
- Additional mounting accessories might be required for some vehicles
Best for: Budget-conscious travelers with cross bars seeking weather-resistant storage
Not ideal for: Owners of vehicles without cross bars or those wanting a more stylish appearance, as color options are limited
- Material:ABS plastic
- Capacity:110 lbs
- Dimensions:53 x 34 x 15 inches
- Color:Black textured surface
- Includes:Cargo box, keys, mounting brackets, hardware
Our verdict“This cargo box suits budget-minded users who prioritize weatherproof durability and straightforward installation on cross bar-equipped vehicles.”
Auto Dynasty Hard Shell Roof Top Mount Cargo Carrier
The Auto Dynasty model makes the list for its generous 11 cubic feet capacity, making it an excellent choice for families or outdoor enthusiasts with bulky gear. Its UV-protected, impact-resistant ABS shell provides reliable weather resistance comparable to the Thule Motion 3, but at a more accessible price point. The wide opening (14 inches) simplifies loading and unloading large or awkward items. While it fits cross bars up to 13 inches wide, its universal fit isn’t guaranteed for all vehicle setups, and its heavier weight (compared to lighter models like the Thule Pulse 2) could pose handling challenges during installation. The limited color options also mean it won’t match every vehicle’s style. Overall, this model is ideal for those needing substantial cargo space with robust weather protection without a premium price tag.
Pros:- Spacious 11 cubic feet capacity for large gear
- Weather-resistant, impact-protected shell keeps contents safe
- Secure lock system for valuables
- Easy tool-free installation simplifies setup
Cons:- Universal fit may not suit all vehicle cross bars
- Heavy weight could be cumbersome for solo handling
- Limited color options reduce aesthetic flexibility
Best for: Families or outdoor adventurers needing large, weatherproof cargo capacity with easy access
Not ideal for: Solo travelers or those with lightweight vehicles who might find handling the heavier box difficult
- Dimensions:53″ L x 34″ W x 15″ H
- Capacity:11 Cubic Feet
- Weight Limit:110 lbs
- Material:UV-protected, weather-resistant ABS
- Mounting Compatibility:Fits cross bars up to 13 inches wide
- Opening Width:14 inches
Our verdict“This cargo box is a strong choice for those prioritizing large capacity and impact resistance on vehicles with compatible cross bars.”
How We Picked
I evaluated each rooftop cargo box based on several key factors: build quality, capacity, ease of installation, security features, weather resistance, and overall value. I prioritized products that balance these attributes well, ensuring they are suitable for a range of needs from casual family trips to more demanding outdoor adventures. The ranking reflects a combination of consumer reviews, brand reputation, and feature analysis, with particular emphasis on usability and durability. Products that excelled in multiple categories and offered unique advantages were placed higher, while those with notable compromises or niche appeal ranked lower.Factors to Consider When Choosing Best Rooftop Cargo Box Hard Shell
Choosing the best rooftop cargo box involves more than just capacity. Consider your typical travel conditions, security needs, and installation preferences to find the right fit. Here are key factors to keep in mind:Capacity and Size
Assess how much gear you need to carry and match that with the cargo box’s volume. Larger models like the Yakima SkyBox NX 18 XLG provide ample space but can be heavier and more challenging to mount. Overestimating capacity can lead to unnecessary weight and difficulty, while underestimating might compromise your storage needs. Think about your typical trips—if you often travel with bulky gear, prioritize higher volume options, but if most trips are short or light, a smaller, easier-to-handle box might be best.
Ease of Installation and Use
Look for models with tool-free mounting systems and dual-side access, which significantly simplify installation and retrieval. Some brands offer quick-mount systems that allow you to attach or remove the box without extra tools—saving time and effort. Consider how often you’ll be removing the box; if frequent, ease of installation becomes a key factor. Also, check if the lid opens from both sides to access gear more conveniently, especially on wider vehicles.
Security Features
Secure locks are vital if you’re leaving your gear unattended. Some models, like the Yakima SkyBox, include integrated SKS locks, which prevent theft and tampering. Basic models may only feature simple latches, which might be sufficient for short trips or low-risk areas. Think about where you’ll be traveling—high-theft zones demand better security. Remember, higher security features usually add to the cost but can protect your investment and gear effectively.
Weather Resistance and Durability
A waterproof, UV-resistant shell protects your gear from rain, snow, and sun damage. Check product specifications for weatherproofing features—some models include sealed edges and waterproof gaskets. Durability also depends on build quality; thicker, reinforced shells are more resistant to impacts and cracks. If you often travel in harsh climates, investing in a weather-resistant model prevents damage and extends the lifespan of your cargo box.
Price and Overall Value
The most expensive models often offer premium features like integrated locks, larger capacity, and superior materials. However, not everyone needs top-tier specs; balance your budget with your actual needs. Sometimes, a mid-range model provides all necessary features without the hefty price tag. Consider long-term value—spending more initially might save money on repairs or replacements later, especially if you frequently travel or carry valuable gear.
Frequently Asked Questions
How much weight can a typical rooftop cargo box hold?
Most rooftop cargo boxes support between 165 and 220 pounds, but this varies by model. Always check the manufacturer’s specifications to avoid overloading, which can compromise safety and damage your vehicle or the cargo box. Distributing weight evenly across the roof is essential for maintaining vehicle stability, especially at higher speeds or in windy conditions. Keep in mind, exceeding weight limits can also void warranties or damage mounting hardware.
Are rooftop cargo boxes waterproof?
Yes, many premium models are designed with waterproof shells and sealed edges to protect your gear from rain, snow, and splashes. Look for features like waterproof gaskets and reinforced corners for maximum protection. However, not all budget options are fully waterproof—some may be water-resistant but still allow moisture ingress over time. When traveling in rainy climates, choosing a true waterproof model ensures your gear stays dry and safe.
Will a larger cargo box fit on my vehicle’s roof?
Before purchasing, measure your vehicle’s roof dimensions and check the cargo box’s footprint. Larger models like the Yakima DeepSpace or Thule Motion 3 require sufficient roof width and crossbar spacing. Some vehicles with low clearance or narrow roofs may not accommodate the biggest options comfortably. Always verify compatibility to avoid issues with installation or clearance, especially if you have roof rails or racks that are close to the vehicle’s edges.
Is it difficult to install and remove a rooftop cargo box?
Modern cargo boxes are designed for straightforward installation, often featuring quick-mount systems that require no tools. Dual-side opening lids also make access easier once mounted. However, larger models can be heavier, requiring some effort or assistance during mounting and removal. If you plan to frequently take the box on and off, prioritize models with simple, tool-free mounting systems to reduce hassle and ensure safety.
What maintenance is needed for a rooftop cargo box?
Regular cleaning with mild soap and water keeps the exterior looking new and prevents buildup of dirt or grime. Check the locks and hinges periodically for smooth operation and apply lubricant if needed. Inspect the mounting hardware for signs of wear or corrosion, especially after exposure to harsh weather. Proper maintenance prolongs the life of your cargo box and keeps it functioning securely and smoothly for many trips.
Conclusion
For most buyers, the Thule Pulse 2 L offers a balanced combination of capacity, security, and ease of use, making it the best overall choice. Those prioritizing value without sacrificing key features should consider the TUFFIOM 13.4 cu.ft. for waterproof protection at a lower price. If you want the best for long-term durability and security, the Yakima SkyBox NX 18 XLG stands out as a premium option. Beginners or occasional users will find models like the SportRack Vista XL easier to install, while frequent travelers in harsh climates should invest in weatherproof, rugged designs. Ultimately, your choice depends on your specific needs and the conditions under which you’ll be using the cargo box.
