FIVKLEMNZCar Rooftop Cargo Carrier Roof Bag Waterproof for All Top of Vehicle with/Without Rack Includes Topper Anti-Slip Mat + Reinforced Straps + 6 Door Hooks + Luggage Lock

This worked great!!I moved out of the horrible dry barren death of the desert and this got ALL my clothes. It was amazing.Fits snuggly on my Honda Civic.I recommend really tightening it down as hard as possible because if not, it will move...slidding toward the back of the car with the air pressure as you drive. I stopped once to re-tighten it.Had no problems. It held tight for a 6 hour drive, even went through light rain, all my clothes stayed dry. Im super pleased with this, it worked perfectly! And saved me money by carrying more, i needed to make less trips.

Quite literally. We wish we had found this years ago, and we feel very dumb for not having thought to search for something like this before. This product has brought us so much comfort and relief on road trips.We have a Toyota Yaris, 2 people and a 90 pound dog who takes up the whole backseat. Doesn’t leave much room for luggage (you wouldn’t believe how efficient I became at packing the car). We were constantly crammed, no matter what, and it made road trips so unpleasant.We were worried about attaching this bag with no roof rack, but it is completely fine and works great. You do not need a roof rack to succeed with this bag.We do not recommend the anti slip mat, it seemed to make the bag slide more. We do recommend wiping the top of your car before installation, to remove dust etc. This helps with grip.This bag holds SO much, even on top of our tiny car. We put most of our luggage in there (except climate controlled or delicate stuff like coolers, backpacks with laptops, etc.) but we could put way more if we wanted to. This bag seems to fit 4 duffles (not the jumbo kind), plus a bunch of other stuff that you can cram between the duffles. We can now move our chairs all the way back, recline them, no more luggage in the way! A miracle for our backs and hips upon arrival!The bag is very sturdy, reliably water proof if sealed correctly (we have driven through numerous thunderstorms), and easy to attach. It takes a bit of effort to place the hooks under the weather stripping, and adjust the bag, but literally who cares this thing is a lifesaver. Make sure to ensure the weather stripping is sealed back properly so you don’t get dripped on in the car when it rains.We recommend placing two hooks in the front on each side, to hold the bag as it’s blown backward while driving, and one or two on each side in the back. No problems this way, it stays on, doesn’t sway at all.We found that as we drove the first few minutes on the highway, the weight adjusts to fall naturally, and the bag strapping may need to be readjusted to put more tension on one side. Not a big deal.Tie the straps up and tuck them if you can so they aren’t flapping and making a racket, or potentially loosening the bag.Use a lock to seal the zipper, not so much for security purposes, but to ensure the zipper stays shut. I think it would anyway, but it gives me peace of mind to know it won’t fly open on the highway. Tuck the lock under the Velcro zipper cover to hold it in place and not put unnecessary stress on the zipper (we have a heavy lock and do not want to misshape the zipper).Oh, and not to mention, a great price. Most roof rack mechanisms cost hundreds of dollars. It hurts our fuel economy slightly, we fill up slightly more (on a 13 hour drive we may fill one more time than usual, but use only a quarter of that tank).10/5 stars. Bravo, and hallelujah. I cannot stop raving about this product.

I am actually decently surprised by this bag. I just returned after a 2600 mile road trip with my family from Seattle to Southern California and back. Overall I am satisfied with this product. I got the 15 cubic feet model and strapped it to our 2012 Prius V and it was more than enough space for all our camping gear, pillows, blankets, and eventually dirty clothes bags.Durability:Only issue here was when we left to head back home, I noticed a few holes in the underside of the bag. I didn't store anything sharp in it so I am at a loss how they got there. Could have been giant desert spiders or my sister's dog. Either way, it made me think this bag is probably a one time use type thing.Weather resistance:I can't really speak to the water/weather resistance as we encountered virtually no rain during this trip except for a brief morning shower at my sister's house in the desert. Everything was dry inside after the rain.Straps:I read other reviews that said the straps needed to be tightened every hour or so at the beginning, but this was not my experience. I never felt the need to pull over and check the straps, other than at pit stops. The straps held up even though I averaged 70 mph, with a maximum speed of 80 mph for a few brief stretches. The only notable issue with the straps was after driving through a heavy side wind for about 60 miles, the straps on the side that got hit the most seemed a bit looser. Other than that, no issues with the straps. I really dislike how the hooks go under the weather stripping, which causes an annoying sound as you drive.MPG:I noticed this bag produced significant drag, reducing my average MPG from the expected 40 to 34 by the end of the trip. I've done big trips in this Prius before and the MPG has at most reduced to 38 when there's a lot of mountain passes/inclines. So it definitely had a major negative effect on the MPG.Security:The little lock that came with the bag (which would stop no one determined to get your stuff) broke instantly when I tried to set a new code, so that was out of the picture. All a thief would need to do is drive up with a pickup truck, quickly cut the straps and shove the bag in his/her truck to get your stuff. It is not very secure. One of the motels we stayed at seemed to be in a not great area so I opted to take the bag off the car and keep it in the room with us. I felt safer with it at other, nicer hotels which had lighting and cameras in the lots.Overall quality:I am impressed with this bag considering it was $60. It did the trick. However the major thing this product did for me was make me decide to the bite the bullet and get a roof rack and a large hard shell cargo carrier so the air can at least travel underneath it, reducing drag. Hard shells also seem to be way more secure.

when my family and i drove from Fl to Ny we was very scared that this product wasn't going to hold all that 18 hours and we been so wrong because its very durable, waterproof, easy to installed, the zipper was strong and covered with thick material and came with a lock for security. Highly recommend this product!worth the money and it's very spacious

Works phenomenally well. Extremely durable. I use it in my roof rack to keep items dry in Oregon. Not a single drop of water got into anything placed inside this. I’ve used it multiple times with no issues. Would purchase again.
