Face it, an overstuffed cabin makes even the swiftest road trip feel as slow as molasses. Even if we had supersonic cars to whiz us coast-to-coast in hours instead of days, we'd still need to stow our super-sized load of stuff. Well, with the Thule Sonic Cargo Box riding up top, your gear stays out of the way and you look like you're traveling at the speed of sound—even if you're cruising the speed limit.
Featuring an Aeronose and an angle-cut back, your Thule Sonic Rooftop Cargo Box slips right through the wind—silent and sleek. What's more, the AcuTight Mounting system installs to most factory or aftermarket racks and makes a distinct “click" once secured. And, thanks to the dual side opening box design, packing and unpacking is a breeze from either side of your ride. Plus, the oversize SecureLock keeps your valuables safe and is easy to use even with gloves.
If you need a lot of room or just a little extra space, the Thule Sonic Roof Cargo Box has you covered. Available in 4 sizes ranging from petite to the gargantuan, there's one for every road trip. And, it's available in your choice of black of silver to accent your topside style. Best yet, Thule builds it from advanced ABS, coats it with a high-gloss automotive finish and backs it with a Lifetime Warranty.

Product arrived on the previously agreed timeline ( not many options to choose from) and with no defects Easy to handle. Don't have references of competitors to compare with but the product is nice and has good quality and finish. Almost unnoticeable while driving which was a positive surprise. Put it in anTown and Country and our average MPG in our trip to the Outer Banks fully loaded was 24 MPG. Capacity wise is what I expected. Relatively flat but you can put in there sport gear.Very happy

Each summer we meet our children and collect our grandchildren for a few weeks visit. This Thule allows us plenty of room for the kid's luggage and assorted things leaving the car roomy for their comfort. We think this is a great investment.

I never thought I would buy one of these until a stray dog showed up & stayed. What? We use my wife's 2014 Volkswagen Jetta SportWagen TDI for medium range travel. Now with two dogs it became necessary to rethink our operation. A new larger vehicle was out of the question. This was the PERFECT solution. It arrived undamaged in what could be the largest, most sturdy cardboard box I've ever seen. Installation was straight forward & our first trip was a success.

The Thule cargo box fits the Subaru Crosstrek perfect. It is easy to get in and out of. There is lots of space for my needs. It travels quiet on the car and it looks good. I am very happy with it.

First - I Love AutoAnything. I always get incredible customer service reps, and I always get a good product, delivered quickly. They have my business for life. Second - Received the Thule Sonic right before a long road trip from NC to IL and back. Couldn't have been happier to have it. Although it feels somewhat flimsy when it is open, it is very sturdy when shut. The grips that hold the box down have built-in tension break, so you don't have to wonder if it's too loose/tight. Once secured it absolutely will not move or slide. We purchased the Medium, and had plenty of space inside. My only concern is that the closing mechanisms don't always line up exactly (probably due to cargo, etc), so a few times I had to work at getting the latch points to line up correctly in order for the lock to engage. If the lock doesn't engage you can't get your key out! Also - in an effort to protect the case during shipping, Thule places 'stick-on' foam padding all around the edges of the cargo box, which is a good thing for the most part. Problem is that if your shipper stores the box on its side, those foam pad will put pressure on the case. Outcome - the left side of our case (around the lock) is slightly bent inward, leaving a slight openeing between the lid at the base. We did get a little water in the case during a hard rain...I'm assuming because of this gap. This wasn't a product defect, rather an outcome of bad shipping probably. That said - once secured to your roof, you'll barely be able to tell it's there, as it has almost no noticeable noise while driving. We had to take our garage door opener off the visor in fear that we'd forget it was up there! Again - phenomenal product, and phenomenal company.
