After looking into over 50 of the best cargo boxes on the market, we bought and tested 7 of the top models to figure out which ones are worthy of toting around your luggage. These boxes were driven thousands of miles through a variety of harsh conditions, from torrential rain to scorching desert heat. Our testers rated them based upon durability, ease of use, security, and aesthetics, each weighted in order of importance. Whether you'll be using your cargo box on a daily basis for long-range road trips or as a place to put some extra gear on anomalous weekend camping trips, our review can help you choose the right one for your needs.

Earning one of the highest scores overall, the Motion XT XL claimed the Editors' Choice Award and the title of Best Overall Cargo Box. This box is incredibly convenient and easy to use with one of the best, most intuitive mounting systems that we have seen to date, usually allowing you to install it in about five minutes. This box is durable and secure, with a locking mechanism that prevents you from accidentally leaving the box unlocked. It has a decently sleek, aesthetically appealing design and is available in two colors — black and off-white — to better match a wider variety of cars.

Unfortunately, this cargo box can take a hefty chunk out of your budget and is one of the most expensive cargo boxes we have reviewed. However, this can be totally worth it if you plan on taking your cargo box on and off your car frequently. If the price isn't right for you, consider saving some money and getting a less-expensive product that is a bit more difficult to install but leaves more room in your budget for what goes inside the box. Excluding price, though, this is the best box in the bunch.

Annoying to install

Searching for a great rooftop box that won't blow your entire gear budget? The Skybox Carbonite by Yakima is a fantastic value, earning it our Best Buy Award. This rock-solid box is another one of our absolute favorites, and we would highly recommend it. The SkyBox Carbonite does a great job of keeping our gear safe, secure, and easily accessible, all at a price that leaves you some money left over to buy gear to fill it. The lid isn't really floppy at all, and the latching system indicated when the SkyBox is unlocked, making it much harder to drive away with an unlocked box accidentally. On top of that, the matte black finish hid scuffs and scrapes much better than the glossy sheen of some of the more sleek and stylish models we have tested.

However, the initial installation is quite a pain. It is still totally doable but if you are planning on leaving the box off of your car most of the time, then throwing it on for a weekend getaway, you will probably be better served by a product that is a bit easier and more convenient when it comes to installation. If you plan on leaving the cargo box installed on a semi-permanent to permanent basis, the more laborious installation procedure shouldn't be a deterrent at all, and you should stick with the SkyBox and spend a little less.

While the majority of the models we tested are elongated to fit items like skis, two of the boxes are of the "short and stumpy" variety. Of these two, one, in particular stood out, with the SportRack Vista earning a Best Buy Award for being the best cargo box you can get when shopping on a tight budget. This box costs significantly less than most of the other models we tested and held its own against them. While it did receive one of the lower scores overall, it is a solid, all-around box with a surprisingly spacious interior and a simple, clean design that complements most cars. It doesn't have many of the additional features that the top boxes do, but you can't go wrong with the SportRack if you are looking to save some cash and save some room in your budget.

The SportRack does have a few significant drawbacks. While the somewhat unique rear opening may look cool, it makes it almost impossible to load or unload the box if it is installed on a tall vehicle such as a large SUV or cargo van. This wasn't problematic on smaller cars, but it still isn't as easy to access your gear as the side loading models. If you're considering the SportRack this is worth taking into account.

Slick looks
Easy use and installation

Very expensive

Cargo boxes aren't the best-looking addition to a vehicle; we get it. And while none look great atop a Porsche, our testers, friends, and family agree that the Thule Hyper XL is the slickest of the bunch. Its low profile goes a long way to keep this model stylish, yet it still manages to fit a ton of gear. Like our Editors' Choice Award winner, the Hyper XL is easy to install and remove from vehicles, and several features and details make regular use a comfortable, happy affair. Built with quality at the forefront of the design, we expect this model to last many years of use.

The drawback on this model is clear — the price. It has one of the highest price tags of the entire bunch, so it's not the model we would recommend to everyone. Regarding utility, you can save hundreds of dollars by selecting another model. However, your vehicle won't look as good. So, there you have it. If you place a high value on style, the Hyper XL won't let you down in the looks or performance departments.

Why You Should Trust Us?


We've been testing and reviewing cargo boxes for over three years and constantly seek new and notable models to add to our review. To ensure objectivity, we purchase all of the products that we test and never accept any free products or incentives from manufacturers. Our cargo box testing team is comprised of Lauren DeLaunay, David Wise, and Steven Tata. Lauren, our head tester, has lived out of her van for several years and taken these boxes all over the country, filling them with gear for many types of trips. David lives in Tahoe and spends a significant amount of time transporting skis, snowboards, and camping equipment throughout the year. In addition to performing thorough real-life testing, David has a degree in mechanical engineering and contributes much expertise regarding each model's aerodynamics and structural design. Steven spends much time traveling with gear for skiing and climbing and is consistently impressed with how much more stylish his Honda Element looks with a cargo box on top of it.

We began testing by unpacking and assembling each model while paying close attention to how easy each one is to install and load with gear. Each box was left on for several weeks and driven for at least three hundred miles. We evaluated how user-friendly each one was for day to day use and noted any significant changes in vehicle handling and fuel economy. The boxes were loaded with a wide variety of equipment, from sleeping bags to climbing ropes to skis. Throughout testing we kept track of any visible wear and tried to find flaws in durability. To evaluate appearance we consulted the OutdoorGearLab testing team and compared the amount of dirt that each model showed after extensive use.

Analysis and Test Results


To rank and score these products and see which cargo carrying box is truly worthy of being crowned king, we began by doing extensive research, looking at over 50 different products, then selected the 7 most promising candidates to purchase and test head-to-head. We developed a comprehensive testing plan, evaluating and judging the performance of each product on everything from its ease of installation to how well it hid scratches and scuffs. We divided our testing process into four weighted rating metrics — Ease of Use, Durability, Security, and Appearance, with each box earning a final score ranging from 0-100.

Value


For those on a budget, the Yakima SkyBox and SportRack Vista are our favorite inexpensive cargo boxes. The SkyBox offers great performance without a shocking price tag. It can fit multiple pairs of skis, is easy to install, and is durably built. The Vista is much shorter and more difficult to install but stands out as a solid basic model if you just need some extra storage and don't plan on using your box for skis. At the top of the line, the Thule Motion XT is a luxury model that is impressively easy to use and quite stylish. It is one of the most expensive models that we tested, along with the Thule Hyper XL.


Ease of Use


Whether you plan to use your cargo box occasionally, or throw it on your roof and leave it there for months, there are a few ways in which some products are considerably easier to use than others. For this metric, worth 40% of the total score, we looked at the assembly process which included mounting and opening and closing the box; this helped us come up with a picture of how much or little effort was required to enjoy the benefits of each box.


Earning some of the top scores of the entire group, the Thule Motion and the Thule Hyper are our absolute favorites when it comes to being convenient and easy to use. These boxes both came essentially assembled and ready to go right out of the box — only requiring you to thread the interior tie-down straps through their brackets.

The AcuTight or PowerClick mounting systems make installation a breeze and usually accomplished in under five minutes. In fact, we spent more time trying to locate where the manufacturer had taped the key than actually mounting it the first time we went to install the Hyper XL.

The PowerClick mounting system on the Hyper and Force is one of the easiest to use that we have seen to date.

Both of these lids open from either side and aren't very floppy at all. Additionally, the Hyper XL also has an integrated light for loading or unloading at night. While it isn't terribly bright, it is useful, though we would still recommend keeping a headlamp on hand if you are going to be using the box at night frequently.

Following this pair of top performers, the Yakima SkyBox and Thule Force XT XL are next regarding ease of use. Both also have dual-side opening, but the handles are less user-friendly. The Force features the same PowerClick mounting system as the more expensive Thule models, but lacks the more convenient locking systems featured on those models. The SkyBox has a slightly more prominent handle than the Force but is not as easy to switch between vehicles. Both have their advantages over each other but feel fairly comparable in terms of overall ease of use.


The Yakima ShowCase 15 and the SportRack Vista are relatively mediocre when it comes to being convenient and easy to use. We weren't enamored with the handle-less design on the ShowCase, but it isn't too difficult to install on a car or access your gear with its dual-opening and quick install mounts — similar to the Yakima SkyBox — but is more work than the top Thule models.

The SportRack Vista's U-Bolt mounting system makes it much slower to install than any of the more expensive models but this isn't much of a problem if you plan to leave it on your car for a while. If you plan to move it on and off your car every weekend then it might be worth checking out the Yakima SkyBox.

Finishing out the back of the pack, the Sidekick by Thule is our least favorite when it comes to ease of use. It took us over an hour to assemble this model and we found it to be tedious to install. Additionally, it also relies on a U-bolt mounting system — similar to the SportRack — that is equally hard to use. To top it off, the box only opens on one side, making it one of the least convenient boxes that we've ever tested.

Durability


Because all of these products are made from similar materials, we looked at the details for clues about their longevity. We drove each box around for weeks without any signs of wear and tear, so this category is primarily concerned with structural integrity and weather resistance. Every box in this review passed the rain and wind tests, which were easy to account for in the Eastern Sierra in springtime, but some had more questionable design features than others. We know you want to invest in a long-lasting roof box that you can count on for countless future adventures, twenty-five percent of the overall score of each product was allotted to durability.


Our main test for durability of materials was in the highly-quantitative lid floppiness. This was a surprisingly easy category to measure since the floppiness was so apparent during regular use. The Thule Motion XT, Hyper XL, and Thule Force XT XL, all stood up tall and proud with minimal flop. The Yakima SkyBox is equally sturdy with hinges that gave us a solid impression of sturdiness and a lid with minimal flop.

All of the boxes do a reasonable job of protecting your gear from the elements and kept our belongings dry, even when driving through a hefty rainstorm — or 20 minutes with a garden hose when the weather didn't cooperate. However, two of the models in our review, the SportRack Vista and Thule SideKick, gave us some cause for concern. These boxes attach to the car with U-bolts. The bolts surround the crossbars of the car and attach through a series of holes in the bottom of the box. Both boxes came with small vinyl circles to cover up the unused holes, and we were wary about their waterproofness. We never found water in the boxes during testing, but the vinyl covers seemed like a flimsy solution compared to the solid slide strips that cover any openings on the higher-end Thule or Yakima models. We suspect that these stickers may rub away over time as you load your gear in and out of the boxes, so both of these boxes received a lower score for durability than their competitors.

None of these boxes showed any signs of damage through normal wear and tear, though most showed a handful of scrapes and scuffs from repeatedly installing and uninstalling each one. One tester managed to bend two of the four mounting clips by not realizing it stuck out further than the car and backing into a cement wall. However, the clips were relatively affordable to replace, and the box itself showed no sign of damage — only a minor scuff.

Security


It would be hard to argue that a roof box was a worthy purchase if you couldn't confidently store your belongings in it — that is their purpose, after all. There was only one box that gave us serious pause here, the Thule Sidekick. In turn, we expanded this category to not only include scores for how secure the box was, but how easy the details of the security system were to use, as well.


Because we had to install the locking mechanism ourselves on the Thule Sidekick, we often found it difficult to line up the dual locks on the flimsy lid. It is possible on this product to turn and remove the key without the latch being lined up properly, leaving you with an unintentionally unlocked box and no way to tell other than lifting the lid and testing it. The other products in our test seemed relatively equal, though, and we were never worried about security. In all these models, it is not possible to remove the key without the box being properly latched and secured, which we consider to be a crucial component.

That being said, some of the boxes we tested did have great, useful indicators to let you know if the box was latched properly or not before trying to remove the key, like the newly designed red indicator of the Thule Motion XT and the big handle of the Yakima Skybox. Both of these inspire extra confidence that your belongings are safe, so we boosted their scores in this metric accordingly.

The Hyper XL securely holds your gear and won't allow you to remove the key if the box is not locked properly.
The Hyper XL securely holds your gear and won't allow you to remove the key if the box is not locked properly.

We really appreciate straightforward, simple security systems and boxes that have additional features to aid in our confidence in the security of our beloved gear. This metric constitutes 20% of the overall score of each cargo box.

While these boxes are all decently secure, we are sure that each model could be broken into without too much effort if someone really wanted and had the proper tools — like a couple of crowbars — so you might want to think twice about leaving particularly pricey gear in your unsupervised cargo box for extended periods of time.

Appearance


Although we tend to prioritize function over form for most categories, we do recognize that cargo boxes can be an eyesore and are something that you'll have to see every day while on your vehicle. To account for this in our review, 15% of each product's final score is based on appearance. Testing was fairly subjective and based upon a group consensus.


There were no shocking designs in this review; all the products we tested generally look like what we'd expect from cargo boxes these days. They did come in a surprising amount of finishes, though, and we had clear preferences.

The Hyper XL does stand out from the group as having the sleekest design — or at least, as sleek a design as a large cargo box can have. It has a glossy finish with a grey "X" on top to accent its appearance. While it does have some of the most panache out of any of these products, its glossy finish does show dirt and grime a bit more than some of the others, as well as any deeper scratches or scuffs.

This box is one of the sleekest and most stylish out of the entire group.

We loved the matte black finish of the Thule Force XT XL and Yakima Skybox Carbonite. We thought the matte finish was unique and tasteful, blending the lines between sophisticated and subtle. It also hides dead bugs well — a problem we hadn't initially thought of. Scratches and scuffs are more subtle on the matte finishes, a problem that glossy models struggled with after many miles.

Additionally, we appreciate that the Thule Motion XT and Yakima ShowCase are available in both gray and black, letting you pick the best match for your car. These are the only products in our review that come in more than one color, and their appearance scores received a boost for versatility. We liked that the gray Motion XT model blends in a little more on the tester's white van. The shiny black finish of the Yakima ShowCase is sleek, classy, and timeless, and looks exactly like what we'd expect from a high-end cargo box.

Comparatively, we thought the textured finishes of the Thule Sidekick and SportRack Vista looked cheap. If we drove fancier cars, we'd be hesitant to put either of these models on top. Either way, appearance may mean more or less to you depending on your personal preferences and could be a good category to ignore if trying to save a few bucks.

Are These Going To Kill My Gas Mileage or Ruin Handling?


You may be wondering if it is even worth getting a cargo box in the first place, due to their impact on vehicle handling and mileage. While we originally had an entire metric devoted to this, we found after testing each of these boxes that there wasn't significant impact on how a variety of different test cars handled, regardless if we were traveling on the freeway at high speeds, over windy mountain passes, or over potholes and bumps on rough roads. These are all large boxes that go on top of your car and increase the wind resistance and drag while you are driving, but they are all pretty much comparable, especially if you drive a larger SUV or truck that isn't particularly aerodynamic in the first place. Drag is hugely dependent on speed as well, so you can probably negate any loss in fuel economy by driving just a bit slower — and you don't really want to be speeding all that much anyways with a fully loaded cargo box on top of your car. Does adding a heavy box to your vehicle affect its power, handling, and fuel efficiency? Sure. Were we able to notice the difference, especially comparative differences between each box? No, not really.

Conclusion


While all the boxes in our review achieve the purpose of shuttling gear from one place to another, our in-depth research has allowed us to identify the strengths and weaknesses of each product to help you pick the perfect one. After weeks of getting to know each box, we're confident in our assessments of the most popular products on the market today. We evaluated durability, appearance, security, and, most importantly, user-friendliness to help you find the perfect cargo-carrying solution for your next road trip.
