Fits almost any car, quickly and easily installed with a roof rack, raised side rails or crossbars; Folded into the storage bag to save space while not in use Please use straps to fasten the roof bag to prevent noise caused ​by excess straps tapping car while driving. OVERSIZED ZIPPER WITH WATER-REPELLENT FLAPS We have found that the straps of other roof boxes can easily tear. That's why we double-reinforced the strap seam. Unlike traditional non-waterproof zippers, we've used a wider zipper and designed it with an enlarged zipper flap to ensure your items stay dry. For maximum security, we use four reinforced straps and six additional reinforcements to securely attach the roof bag throughout the journey. Thus, the safety of the driver and passengers is guaranteed and there is no need to worry about possible dangers while driving!

The soft material makes it foldable and packed in a small bag, then you can put it in the car. Works with ALL Vehicles - Sedans, SUVs or Full Size Vans - Holds like 5 medium suitcases

Review: Exceeded our expectations. - Very happy with this product and it definitely held quite a bit of our gear. It rained in excess of 4 hours one way and 2 hours back, with no evidence of leakage whatsoever. As it was hard to visualize during the initial product comparison, I'm glad I purchased the 20ft² carrier instead of the 15ft² (Go bigger.. always!) These units will definitely fit the roof of a Mini as well.. not that we used it on this rental.. just a good-to-know observation. Regardless of the fact we used a rental vehicle, a protective non-slip mat for the roof, under the unit is highly suggested.. as a just-in-case scenario. The zipper system and velcro flap that covers it seem solid. I did find it tricky to start either side's zippers when closing. So I'd highly recommend not to fully open zippers and stop about 8 inches before reaching the "fully" unzipped position. Following this advice will not impede storage in the least. I do have to mention that you will have to get creative with the included bag for the carrier, as after the initial unpacking.. you will NEVER get it folded as skillfully back in. As a side note, in the provided instruction manual, you are told that you should not put live pets into the carrier. Sage advice indeed. I'd also suggest that it is unsuitable for unalive pets as well.
Review: Waterproof and Super Spacious – A Road Trip Essential - This rooftop cargo carrier exceeded our expectations! We used it for a long road trip with our family of 10, and it fit everything we needed with room to spare. Completely waterproof—everything stayed dry through heavy rain—and the belts held it securely in place for hundreds of miles. Easy to install and remove, and we even got a few compliments at rest stops. Highly recommend for large families or anyone needing serious extra space on the road!

### ⭐⭐⭐⭐⭐ Great for camping and traveling on a budget!
*by B***T on 26 May 2025*

Update: We’ve had this almost two years now and it has still held up really great for us. It’s been with us on dozens of camping trips and a couple of long trips from TX to Colorado. On one of those trips, we ran into some really cold weather causing ice to accumulate on the bag, still no problems. It’s seen heavy rain and kept our gear dry. Really recommend this product, we are very happy with it still! Original: I’ve been really impressed with this! We did not have the budget for something top of the line, but wanted something heavy duty that would last us a long time. We use this for when we go camping and it fits just about all of our gear - no longer is my kiddo sitting in the back seat squished like a sardine! It is very easy to get set up and is very secure. We drive on Texas highways where we go 70-75mph and have had no issues whatsoever. It’s kept our belongings safe in the rain, and after many uses since its purchase..we’ve found that it really is very durable. My biggest concern for products like this is always issues with zippers - happy to report that so far, we’ve had zero issues with anything! Highly recommend!
