By all means, it promises quality, durability, and reliability. Aesthetics of Force Cargo Box is another thing to look forward to!

All of the praise applies to their impressive SkyBox Carbonite model.

Large Cargo Space

The SkyBox Carbonite offers 21 cubic feet of cargo space, thereby qualifying as one of the biggest cargo boxes to exist in the market. But that does not make it heavy at all!

SportRack Vista XL Cargo Box

SportRack Vista XL Cargo Box
1,661 Reviews
SportRack Vista XL Cargo Box
  • 18 cubic foot (510 L) internal cargo capacity
  • Made from durable UV-resistant ABS material
  • Rear opening for easy access away from traffic
  • Tool-free mounting hardware for easy installation and removal
  • Includes key and lock to secure contents in the box, and the box to your rack

SportRack Vista XL can be termed as the best bang for the buck, seeing its low price and top-grade design.

With a whopping 18 cubic feet capacity, Vista XL is roomy enough to accommodate most of your belongings needed for long trips.

Aerodynamic Design

Vista XL showcases a nice aerodynamic shape and offers plenty of height as compared to Thule or Yakima models. In other words, you can stash larger items in this spacious rooftop carrier hassle-freely.

It measures 19” height, 63” length and 38” width.


SportRack Roof Rack Cargo Box is made from high-quality ABS plastic, which distinctly makes it durable. Besides, it can endure UV rays for years without showing any signs of fading. For the sake of security, it comes with a built-in cylinder lock to prevent unauthorized access.

It offers 18 cu.ft. of large space and can hold up to 100 pounds of your gear.

Rear Opening

Attaching this roof cargo box is a breeze, but you will require a roof rack system for that. SportRack includes a U-bolt hardware mounting kit in the package for quick setup and removal.

It is compatible with round, square and most factory racks.

Another key point here is that SportRack Vista XL only opens from the rear, unlike other carriers that can be accessed from left or right. But, it comes down to your preference.

​One drawback of such design is that it becomes tough to unload or load cargo box if your vehicle has a high profile like an SUV or Van.

  • ​Large 18 cu. Ft. storage space
  • ​Easy to install
  • ​Mounting kit provided
  • ​Lock included
  • ​Durable and UV-resistant ABS plastic body

RoofBag Waterproof Rooftop Carrier
  • FITS ALL CARS: With or without rack, sunroof, moonroof. The original RoofBag car roof cargo carrier was designed in the USA to safely fit any model car. The generous dimensions of the 15 cubic feet model (48" L, 38" W, 11"-18" H) are large enough to hold the contents of 5 suitcases. You’ll be surprised how spacious it is. It will fit safely on any roof 58" or longer (SUVs, vans, large sedans, pickup trucks). Large Set includes Liner Bags for easier packing and unpacking your rooftop cargo bag
  • MOST SECURE DESIGN: Your belongings are safe at any highway speed with the strongest nylon straps: 1.5” wide, 3,000 lbs strong. For increased safety, straps are not sewn to the car roof bag. RoofBag’s exclusive pass-through straps are safe: tested for 18 years. They don’t interfere with side curtains: they enter at corner of door frame. Door hooks or clips are not safe in the US: most US cars don’t have a required lip under door gasket. Tip: If you car has lip, buy door hooks from RoofBag store
  • TRULY WATERPROOF: RoofBag car topper keeps your valued contents dry, offering the benefits of a rigid car top carrier and the practicality of a cargo bag. To ensure waterproofness, RoofBag is made from a single piece of waterproof material and has no exposed stitching. The double flap protecting the zipper is semi-rigid and stays in place without the need for velcro. Straps are water-repellent. Zipper is unique: has no gap between the two halves.

Built with heavy fabric to reduce noise, RoofBag was engineered to maximize storage space and fuel economy. We make 2 Sizes: 11 and 15 cu ft, which fit safely on any car. Larger bags than 15 cu ft greatly increase gas use and are unstable and noisy. Tip: fill bag completely to keep aerodynamic shape - Leave 8” clear roof in front of bag

For a little lesser than Rightline Gear Sport 2, this RoofBag Car Top Carrier is another option for people who like textile cargo bag.

Buying Guide for Best Cargo Box

Your best cargo box has to have good aerodynamic shape, easy installation process, and quality construction.

There are myriads of cargo boxes out there to choose from. To make an informed decision, you need to know what to look for in a cargo box before spending your money.

Following are the few factors you need to consider before buying any cargo box:


The material of the cargo box plays a vital role in deciding its durability and noise it makes.

  • Poorly constructed cargo boxes will rattle even during normal highway speed, whereas heavy-duty carriers will withstand long trips.
  • High-quality cargo boxes will make use of premium materials like ABS plastic and others. The best cargo box is the one that is thick and has multiple layers of plastic used to make it rugged and weather-resistant.
  • Cheaper models will use thin plastic that won’t be able to withstand bad weather elements and UV rays. Some might even crack due to cold temperatures.

As for Cargo bags, they are made from a Polyester fabric similar to what is used for backpacks.

​Manufacturers might incorporate waterproof design elements like double vinyl coating or welded seams, etc. to make it 100{6c74ca63e013bf7fdc90f42082e9494ee47031617a282fbe0976712ddae472a0} leak proof.

Mounting System

Mounting system must be such that it should allow quick and easy installation. You don’t want to spend hours trying to figure out how the cargo box goes over your vehicle.

Look for the one that comes with a mounting kit and does not require tools for installation.

Some cargo boxes come with U bolts, Quick-Grip locks, and other such systems to attach the cargo box to the roof.

​U bolts are fitted beneath the roof rack and then affixed to the two holes provided in the cargo box. Whereas, Quick-Grip locks are somewhat similar to U bolts, but they have a clamp to hold the box in place.

Ease of access

Ease of access is an essential factor to consider, especially when you load/unload gear from the cargo box very often. Best cargo box allows seamless loading/unloading process, without demanding much effort from the user.

Check whether your cargo box has a dual-side opening for quick access, has internal lid stiffeners to keep it open on its own or hydraulic opening to make things easier. All these minimal features hold significant value as to how easy it is to access your cargo box.


Car Top Carriers made from fabric are generally less secure than hard cargo boxes. That’s because they do not incorporate any lock system.

On the other hand, hard cargo boxes mostly come with a secure lock system to prevent your stuff from thieves.

High-end cargo boxes will feature some advanced technology for complete sealing, whereas average models come with traditional padlock and key system.

Size of the cargo box will not only decide its fit with the vehicle but also determine what load it can carry. If you are someone who engages in camping and sports activities frequently, you would want your best cargo box to hold necessary equipment viz. skis, snowboards, etc.

Small cargo box will be hard to access when installed on large vehicles. Whereas, the large box might interfere with the rear hatch of small cars. Make sure you check the capacity and dimensions of the box before purchase.

Aerodynamic Shape

Boxy cargo boxes will promote wind noise and wind resistance, costing you more money as it reduces the miles per gallon. Brands today are striving to design aerodynamic, streamlined shape for cargo boxes. This is, so it slices through the wind, thereby reducing wind noise, wind resistance and improving fuel economy.

​The best cargo box is the one that is curvy and sleek, does not have sharp edges that caters noise and wind resistance.


High-end cargo boxes are backed with a Lifetime warranty, given their premium build and reliable design.

Fabric-style car top carriers will have around 1 or 2 years of warranty. Make sure you check the Manufacturer’s warranty before you buy.

​Excellent warranty means the Manufacturer is confident about the quality of their cargo box.

FAQs regarding Cargo Boxes

Q. How to attach a cargo box to your car?

Nearly all roof cargo boxes need a roof rack with crossbars at the top of the vehicle for attachment. Your car might have round, square, aerodynamic-style or factory crossbars.

If not, you need to buy one separately, that attaches precisely to your roof.

​Cargo boxes mostly come included with mounting hardware (U bolts or Quick-Grip knobs) and setup instructions. You can easily attach it to your vehicle’s rooftop accordingly.

Q. How much weight can a cargo box withstand?

Most of the cargo boxes can hold 90 pounds up to 110 pounds of weight. It depends on the type of model.

Q. What features make it easier to load/unload gear from a cargo box?

 Dual-opening design is what makes it easier upon you to load/unload your gear from a cargo box.

Q. Cargo Bags vs. Cargo Box- which is better?

The cargo box is ideal to choose if you often go for long trips and haul heavy gear with you. They have maximum carrying capacity, strong build and are more secure than cargo bags. Most of them can even carry sporting equipment.

Whereas, cargo bags are better for infrequent travelers, as they are easy to mount, lightweight and fairly waterproof. Even a single person can install it effortlessly. Another advantage of cargo bags is that they can hold oddly shaped objects and fold down easily when not in use.

The Final Word

Considering all things, we conclude that the Thule Force is one of the best cargo boxes out of all the others mentioned in this review.

Everything you’d expect in a premium cargo box, you’ll find it in the Thule Force, given it comes from a leading brand.

Although a bit expensive, Thule Force abides by its high-price by offering excellent durability, large storage space, and sleek aerodynamic shape.

Main highlights of the Thule Force include its diamond-textured lid, thick five-layered ABS plastic body and “Quick-Grip” knobs that allow quick setup.

Another key point is that you can open it from both sides and lock it securely with Thule’s SecureLock technology. It is optimal for campers or active athletes who usually haul around snowboards and skis.
