Many travellers face the challenge of maximizing storage space without cramming everything inside your vehicle. In this post, we’ll explore two popular options: Car roof boxes and Car roof bags. By examining their differences in capacity, convenience, security, and cost, you’ll be equipped to make the best choice for your adventure. Let’s dive in and find the perfect solution to enhance your journey!



Understanding Car Roof Boxes
Car roof boxes are essential accessories for anyone looking to expand their vehicle’s storage capacity without compromising comfort. Whether you’re embarking on a family road trip or heading out for a weekend adventure, these storage solutions can be game-changers. Let’s look into what a car roof box is, its structure, typical features, and how it can enhance your travel experience.



What is a Car Roof Box?
A car roof box is a hard-shell storage container that is mounted on the roof of a vehicle. Designed to carry luggage, sports equipment, or other items, it can significantly increase your car’s storage capability. Roof boxes are available in various sizes and styles to fit different vehicle types and needs.
Structure of a Roof Box
Roof boxes are typically made from durable materials like ABS plastic or fiberglass, which provide weather resistance and added security. They are designed to be aerodynamic, reducing wind noise and drag while driving.
Here are some common structural features:
- Lockable Lid: Most roof boxes come with a locking mechanism to secure your belongings.
- Dual-Sided Opening: Some models, like the Thule Motion XT, offer dual-sided openings for easy access from either side of the vehicle.
- Mounting System: Roof boxes usually include an easy-to-use mounting system, compatible with most roof racks.
Typical Features of a Car Roof Box
When shopping for a car roof box, consider the following features:
- Size Options: Roof boxes range from compact models for a couple of bags to larger ones that can accommodate multiple suitcases or sports gear.
- Weight Capacity: Most roof boxes can carry between 75 to 200 pounds, depending on the model.
- Material Quality: Look for UV-resistant and weatherproof materials to ensure longevity.
- Compatibility: Ensure the box fits your vehicle’s roof rack. Brands like Yakima and Thule offer compatibility guides on their websites.
Popular Models to Consider
- Thule Motion XT: Known for its aerodynamic design and spacious interior, this model can hold up to 16 cubic feet of gear. It also features a dual-side opening for convenience.
- Yakima SkyBox Carbonite: This versatile option comes in various sizes and is constructed from durable material that’s both lightweight and weather-resistant.
- INNO Wedge: If you’re looking for a sleek design, the INNO Wedge is a great choice, offering a low-profile shape and quiet aerodynamics.
Types of Vehicles That Can Accommodate Roof Boxes
Most vehicles can accommodate roof boxes, but it’s essential to check compatibility. Here are some vehicle types that can easily use roof boxes:
Vehicle Type | Compatibility |
---|---|
SUVs | Most models can handle larger roof boxes |
Sedans | Compact boxes work best |
Crossovers | Generally compatible with mid-size models |
Minivans | Ample space for larger boxes |
Advantages of Using a Roof Box
Car roof boxes offer numerous benefits that can make your travel experience more enjoyable and efficient.
Increased Protection from Weather Elements
Roof boxes provide a protective enclosure for your belongings. Unlike soft bags, which can be susceptible to rain, snow, or dirt, a hard-shell roof box keeps items safe from the elements. For instance, the Thule Force XT is known for its weather-resistant design that keeps your gear dry during inclement weather.
Enhanced Security for Belongings
A roof box not only protects your belongings but also secures them. Many models come with built-in locks, deterring theft and providing peace of mind while you’re away from your vehicle. The Yakima SkyBox, for example, features a key-and-lock system to keep your items safe.
Ease of Loading and Unloading
Loading and unloading can be a breeze with a roof box, especially when it has a dual-side opening feature. This is perfect for families or anyone traveling with a lot of luggage. The extra height can also make it easier to store awkwardly shaped items, such as skis or camping gear.
Practical Examples of Usage
- For Ski Trips: A roof box like the Thule SnowPack can easily carry your skis or snowboards, freeing up valuable space inside the vehicle.
- Family Road Trips: Consider using the Yakima SkyBox for family vacations, where you need extra space for suitcases, strollers, and more.
In summary, a car roof box is an invaluable asset for anyone seeking additional cargo space while traveling. With various models available, from the Thule Motion XT to the Yakima SkyBox, there’s a roof box that can meet your specific needs and enhance your travel experience.
Exploring Car Roof Bags
Car roof bags are an innovative solution for travellers looking to maximise their vehicle’s storage capacity without the bulkiness and expense of traditional roof boxes. These flexible storage options are especially useful for family trips, camping adventures, or any journey requiring extra cargo space. Let’s dive deeper into what car roof bags are, how they differ from roof boxes, and their pros and cons.


What Are Car Roof Bags?
Car roof bags, also known as rooftop cargo bags, are soft-sided storage solutions designed to be mounted on the roof of a vehicle. Typically made from durable, waterproof materials, these bags are ideal for carrying a variety of items, from luggage and camping gear to outdoor sporting equipment. Some popular models include:
- Thule Roof Bag: Known for its durability and weather resistance.
- Rooftop Cargo Bag by Rightline Gear: Features a universal fit and innovative design that keeps it securely attached.
- AmazonBasics Car Roof Bag: A budget-friendly option that still offers decent quality and protection.
How Do Car Roof Bags Differ from Roof Boxes?
While both car roof bags and roof boxes serve the purpose of additional storage, they have distinct differences that may influence your choice depending on your needs.
Feature | Car Roof Bags | Roof Boxes |
---|---|---|
Weight | Lightweight and easy to handle | Heavier and less flexible |
Storage | Foldable and compact when not in use | Requires dedicated space |
Price | Generally more affordable | Typically more expensive |
Security | Less secure against theft | Lockable and more secure |
Weather Protection | Moderate weather resistance | Superior weather resistance |
The Flexibility of Roof Bags
Lightweight Nature
One of the standout features of car roof bags is their lightweight design. Unlike roof boxes that can add considerable weight to your vehicle’s roof, roof bags are easy to lift and install. This makes them an ideal choice for spontaneous road trips or for those who may not have the physical capability to manage heavier equipment.
Easy Storage When Not in Use
Car roof bags can be effortlessly folded and stored away when not in use. This is particularly beneficial for individuals with limited garage or storage space. For example, the Rightline Gear Sport 1 Car Top Carrier can be easily stowed in a wardrobe or even in the boot of your vehicle when not required, freeing up space for other items.
Lower Price Point
Budget-conscious travellers will appreciate that car roof bags usually come at a lower price point compared to roof boxes. For instance, while a sturdy roof box can range from £300 to £800 or more, quality roof bags can be found for as little as £50 to £200. This makes them an attractive option for families or individuals looking to save money without sacrificing utility.
Potential Downsides of Roof Bags
While car roof bags offer numerous benefits, there are some downsides to consider as well.
Less Protection Against Theft
Since car roof bags are soft-sided, they provide less security against theft than roof boxes, which often come with locking mechanisms. If you plan on stopping frequently on your journey or are parked in less secure areas, it might be worth investing in additional security measures, such as a cable lock.
Adverse Weather Conditions
Although many roof bags are designed to be water-resistant, they may not offer the same level of protection as roof boxes in extreme weather conditions. For example, heavy rain or snow can seep through if the bag is not adequately sealed or if it’s made from lower-quality materials. The Thule Motion XT, a popular roof box, is designed to withstand the elements much better than most soft-sided bags.
Limited Structural Support
Roof bags typically do not have the same structural integrity as roof boxes. This means that fragile items may require extra padding or careful packing to prevent damage during transport. The AmazonBasics Rooftop Cargo Carrier, while affordable, may not be ideal for delicate items unless packed with care.
By weighing the pros and cons of car roof bags versus roof boxes, you can make an informed decision that best suits your travel needs. Whether you opt for a roof bag like the Rightline Gear Sport 2 for its flexibility and affordability or a solid roof box for maximum protection, both options can enhance your road trip experience.
Factors to Consider When Choosing Between a Roof Box and a Roof Bag
When it comes to maximising your vehicle’s cargo space for an adventure, choosing between a roof box and a roof bag can be a daunting task. Each option comes with its unique benefits and considerations. Here are the key factors to help you make an informed decision tailored to your needs.
1. Vehicle Compatibility
Not all vehicles are created equal. Before making a decision, consider how well each option will fit your particular model.
- Roof Box: Roof boxes typically require crossbars on your vehicle’s roof. If you have a compact car, options like the Thule Motion XT (available in sizes ranging from 16 to 22 cubic feet) may be a perfect fit. Ensure that your car’s roof can support the weight of the box plus cargo.
- Roof Bag: Roof bags, such as the Rooftop Cargo Bag by XCAR, can often be strapped directly to your roof without crossbars. This makes them compatible with more vehicle types, including those without existing roof racks.
2. Volume of Items Needed for Transport
The volume of items you plan to transport plays a crucial role in your decision.
- Roof Box: If you’re carrying bulky items like skis, snowboards, or camping gear, a hard-shell roof box like the Yakima SkyBox, which offers up to 21 cubic feet of storage, can provide the necessary space and protection.
- Roof Bag: For lighter, less bulky items, consider a roof bag. The Keeper Waterproof Roof Bag is a great choice for soft items like clothing or sleeping bags, with a capacity of up to 15 cubic feet.
3. Frequency of Use
How often you plan to use your roof storage can influence your choice significantly.
- Frequent Use: If you’re a regular traveler, a durable and secure roof box like the INNO Shadow 16 can be a wise investment. Its locking mechanism provides peace of mind while parked.
- Occasional Use: If your trips are infrequent, a roof bag may be more economical. The AmazonBasics Rooftop Cargo Carrier offers a compact solution for occasional road trips without the need for a long-term commitment.
4. Budget Constraints
Your budget can play a significant role in your decision-making process.
- Roof Box Pricing: Roof boxes generally range from $300 to $800. For instance, the Thule Force XT offers a reliable option at around $400, making it a good mid-range choice with great capacity.
- Roof Bag Pricing: Roof bags are more budget-friendly, typically ranging from $50 to $200. The Rightline Gear Sport 3 is an excellent choice at around $150, offering waterproof features without breaking the bank.
5. Personal Preferences for Convenience and Security
How you value convenience and security can heavily influence your choice.
- Convenience: Roof boxes are generally easier to load and unload due to their hard-shell design and opening mechanism. Models like the Yakima EXO, which features an innovative slide-out design, allow easy access without needing to climb on the car.
- Security: For those who prioritise security, roof boxes provide a more robust solution. The Thule Pulse is equipped with a central locking system, ensuring that your belongings are secured while you’re away from your vehicle.
6. Evaluating Specific Needs for Different Types of Trips
Consider the nature of your trips to determine which option fits best.
- Family Road Trips: If you’re packing for a family vacation, a spacious roof box like the Ski Box by SportRack, providing up to 18 cubic feet, can accommodate your family’s gear securely.
- Camping Adventures: For camping trips where you need to carry bulky sleeping bags and tents, a flexible roof bag such as the Goplus Waterproof Cargo Carrier (with a capacity of 15 cubic feet) can be ideal, as it can be easily folded and stored when not in use.
Summary Table of Key Considerations
Factor | Roof Box | Roof Bag |
---|---|---|
Vehicle Compatibility | Requires crossbars | Fits many cars without crossbars |
Volume | Larger capacity available | Suitable for lighter items |
Frequency of Use | Best for frequent travelers | Good for occasional use |
Budget | £300 – £800 | £50 – £200 |
Convenience | Easier to load/unload | Lightweight, can be compacted |
Security | More secure with locks | Less secure |
Best for | Family trips, bulky gear | Camping, light items |
By considering these factors, you’ll be well-equipped to choose between a roof box and a roof bag that best fits your lifestyle and travel needs. Happy adventuring!

We’ve explored the various modes of transportation, accommodations, and itineraries, highlighting their pros and cons. As you weigh your choices, consider factors such as budget, comfort, and the type of experience you seek. If you prioritise flexibility and adventure, a road trip in your own vehicle might be ideal.
