It is a one star for my lifestyle. It's okay if you don't need something very durable like I do. I travel for work and for play all over the Western states, Pacific Northwest mostly, days and weeks at a time. Doesn't withstand alot of usage. If you do purchase it make sure the straps that tighten the load are tighten down as much as possible and then give it another tug for good measure...any air pockets anywhere inside are BAD. The inside coating will wear off with the slightest rubbing from the objects packed. (Make sure you don't pack anything with a square corner, either. Such as boxes.) The white piping on the outside will break in spots with movement also. I purchased another thinking the first was a lemon and tried to be extremely careful how it was packed and strapped. Even stopping down the road 50 miles to check and tighten any loosened straps from settling. The piping didn't crack as badly like the first but still the inside has pealed from the outer material in spots. And do beware, IT IS ABSOLUTELY NOT WATERPROOF and can BARELY be classified as weather resistant. If it is raining or if any moisture(including fog) is in the air it WILL find it's way in no matter how careful you zip it up. If you don't plan to use it but once a year on a sunny day, travel far(50 miles @ less than 50mph) or run into any bad weather/wind it will be okay and work for you.

I bought the cargo bag for a trip from Central NJ to Myrtle Beach, SC. I did not and do not plan to use the bag extensively, so the lower price tag fit my needs perfectly. I read all of the reviews before purchasing the bag so I was prepared. I stuffed (duffle/canvas-like bags only - didn't want to ding up the SUV) in heavy duty trash bags and sprayed the bag with water repellent. Since I'm overly cautious and this was my first foray into the "rooftop cargo bag" scene, I also spent an extra $8 at my local auto store for 2 bungee cords. I was able to pack a lot of gear in the bag. We had no problems with attaching and securing the bag and once we criss-crossed the bungee cords across the top, the bag didn't budge an inch. I didn't see any difference in the SUV's gas mileage or feel any drag when driving at higher speeds on the expressways. It did rain for hours coming and going, so there was a little wetness at the bottom of the bag where the rain sat and the sun couldn't reach. I really did expect this if we were hit with heavy rains (which we were) so I made sure only blankets, towels, bathmats and that sort of stuff was packed at the bottom to serve as a buffer between the duffle bags and the auto rooftop. Overall, the cargo bag did its job and the price was right.

We purchased the Thule cargo bag for our recent trip to Florida. It rained at various times throughout the trip and nothing was wet inside. We also sprayed the outside with a water repellent prior to our trip...that may have helped. We were concerned about not having crossbars on the cargo rack, but it worked out just fine!

We got this bag as a last minute choice for a trip to Moab for my Mazda 6. It is bigger then I thought it would be which is awesome at how much stuff I can cram in it. I do have to mount it sideways on my car to fit right since it is longer then the space my rack has available on top. After some adjusting up top it fits great. I hear less noise from wind with this on then without it.
Just becareful with the top of your car and don't scratch it.

Holds a ton but can compress down if you've got less—that means less noise and better gas mileage.

We had to trim the straps (which come very long) because they were flapping.

We use it for family trips (2 adults, 2 children), the children can pack it like a suitcase on the bed and we load it on the car, then drag the whole bag to the cabin. This works a little better than I think a hard case would, where we'd be packing and unpacking more often.

I just used this cargo bag on my Ford Explorer for a trip down to the Smokey Mountains. We drove down in the middle of the rain and wind that Hurricane Ivan was throwing the TN valley. The bag stayed put and although not waterproof, was pretty helpful in being water resistant. I'm not sure that anything would have sustained the rain we saw on our drive. We were in rain for a good 5 hrs. We packed our duffles inside large garbage bags inside the Quest. Our duffles were, for the most part, dry as a bone when we got there. The garbage bags weren't air-tight, which is the reason some wetness did seep in. I was impressed!

Just drove 2400 miles from Rhode Island to Texas with the Quest holding clothes and camping gear. It did a great job: no noise, no difference in gas mileage. It's not waterproof, so I packed things in garbage bags and even through some amazing rains everything came through unscathed. Best of all, it packs into a tiny little cargo bag till next time.

What a great aerodynamic cargo bag. Much better than all the other boxy designs. A snap to install, easy to load and you can't beat the price. A must have for anyone with a roof rack on their SUV.

Great customer service but I would not recommend this cargo bag. After one trip of 700 miles a seam came apart and the inside of the bag flaked terribly. This may have been an isolated incident, but I was fairly disgusted with the quality. However, the quality of customer support is great because they stood behind the product 100%. Thanks guys.

The bag was well designed and definitely saved me room in the car. I only had two problems with it. 1) Had it been waterproof, I would not have had to wrap everything in trash bags to pack it. 2) The clips are made of cheap plastic and I already broke one strapping it down for the ride home.
Other than these two problems, it did what it was supposed to do. Friction is doing a visible job of wearing off the water resistant coating on the inside of the bag where it rubbed on the corner of my suitcase, but that is to be expected.

Summary: If the clips were made a little hardier, or Thule sent extras, I would recommend this bag in a second.

The Best! No complaints!
No "flapping" noises in my 16 hour trip!
Works well with standard roof racks.

If you're looking for a carry top bag that is easy to load and easy to mount to your car this is the carrier for you. It has very good hold downs, and it didn't seem to add much wind resistance to my car. If I'm looking a similar product in the future, I'll be looking at a Thule product first for sure.

We just took the Thule cargo bag on a 750 mile trip. That bag held a lot of stuff! It holds a lot more stuff than it looks like it can. It was simple to install to the roof rack, and worked perfect keeping all of our souvenirs safe until we got back home. Great bag for the price!

Purchased the Thule Quest cargo bag for our summer vacation trip. While not the largest bag on the market, it was still a great space-saver for our family of 5. We encountered a few showers and everything stayed dry. I checked the straps at every stop on a 500-plus mile one-way trip and all of them were secure. I would highly recommend this product and Backcountry (excellent service).

It is not waterproof!
