Great Product!
The Thule Motion 3L is an excellent rooftop cargo box that delivers on both form and function. Its easy installation makes it a hassle-free addition to any road trip setup, even for first-time users (able to install by myself). The sleek, modern design not only looks great but also complements a wide range of vehicle styles and it fit our Subaru Outback perfectly! Most impressively, it remains quiet while driving, minimizing wind noise and allowing for a more comfortable ride. Overall, the Motion 3L stands out as a premium, user-friendly solution for anyone in need of extra storage space.

Titan grey is darker than you think
Bought the motion 3 size L titan grey to match my 2023 Honda hrv dark grey with wingbar edge bars and it couldn't have been a better fit size wise and color wise. Very pleased with the size and overall look on my HRV. The xl probably woulda fit but I have zero hang over the windshield with the Large and my entire quiver of skis fits in the large so why add the extra drag on my gas mileage if I dont have to. 4th box ive had and this one is definitely the nicest. Love the add on floor liner, light and 1 key setup with the bars. Install of bars and box took a little over an hour and did it alone. Very straight forward start to finish. Would only be happier if it was snowing!

Visually pleasing, significant capacity
I bought this for an 8-hour road trip and am glad that I did. This unit looks very sharp on top of our Sienna and freed up a ton of room in the cabin.

Thule cargo xL
Looks great on my 2024 Honda Pilot. Easy to load any luggage. Helps that you can do it on either side.

Best cargo carrier!
We crammed 6 people in our van and all our belongings in the Thule carrier above us for an 11-hour ride to the beach. No drag on the car just lots of extra leg room for us. It easily locks and stayed secure the entire ride. It’s also sleek and cool looking.

Great so far!
I've only used it for 1 trip on my R1T but install and breakdown were super easy and it looks great!

Sleek and elegant
So I just bought a new white 4Runner and it comes with shiny black around the wheel wells - my former Thule wouldn’t go so well. I purchased this because of it was also shiny and I can open it from both sides. The only problem is on the passenger side I was unable to unlock until I used some WD40 and my friend had to manhandle it to possibly loosen the tumblers within the lock. It still isn’t near as smooth as the left side which is unfortunate

Mounted on my Subaru Ascent, the Thule Motion 3 is a sleek, spacious roof box that’s perfect for road trips. Spacious and has dual-side opening, it’s super convenient to load and unload. Installation is easy, and it stays secure and quiet on the road. Durable and stylish — a top choice for extra cargo space!
