Car Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Heavy Duty 720D Car Roof Cargo Carrier for All Vehicle with/Without Racks - Storage Bag, Anti-Slip Mat,4 Door Hooks & 2 Extra Straps

I have only used this once for our summer vacation this year, but it was easy to set up, very durable and strong, and had minimal affect on fuel economy. It can fit way more items than it appears. I do think the straps that came with it (to strap around the carrier in addition to the built in corner straps) are inadequate, so I purchased Ratchet straps which I felt much more secure with. I highly recommend that you do that, cheap purchase at Lowe's or Home Depot and well worth the security. Very happy with this purchase.

I was skeptical at first. I don't have luggage rack bars on my Durango, but did have some anchor points up top. I used some spring clips and attached the straps to them.Just drove 2500 miles with 5 different places to spend the night. It held perfectly. No damage anywhere. Watertight, and we went through bad weather.Definitely worth it!

This was a must have for our 8 hour road trip to the beach. Gave us the extra room needed as we have two kids and a grandparent. Lost of straps to hock set up with you roof rack. If you don’t have any roof racks it sets up as well with hooks that sits right under the door weather stripping, just get those straps tight and tape them down your good to go!

So far trying to leave and I can’t get this thing working cause I gotta figure out what The freaking instructions which don’t tell you nothing I want to cost so bad it’s unbelievable. I’m so frustrated with this product.

Absolutely perfect. We ran through rain and it's 100 percent waterproof. Zips well,it was a great deal. We love that it's made from thick material. Held up great and never moved an inch. We drove over 200 miles first use. We love it.

I drove for 8 hours in a torrential rain. There was a leak but it honestly surprised me that most of the items were dry. I think if I hadn't been driving the entire time in the rain there would be no leaks. Overall I think it was a good purchase, just not as weatherproof and waterproof as I would've liked.

I was skeptical at first but this thing holds strong for my 1000-mile trip

It's good for summer days but I went on a road trip and went through tons of rain. and all my stuff got soaked. It also did not come with any instructions

Product is great for extra room in a compact car. Used on a 16hr drive going highway speeds and it held up just fine. Super handy!
