FIVKLEMNZ 21 Cubic Car 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.

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

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.

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.

For context, I bought the 15 cubic inch bag.So I will be taking a trip to Mexico in about a month and a half and needed to free up some room in my car. For context I have a 2018 Camaro. My wife and I will be going with our daughter and she overpacks like crazy. We both have 32inx20inx13in suitcases for ourselves, though I may take a smaller one this time around. Anyway, I've been looking around for something like this bag due to my car being small inside, the trunk fits at least one huge suitcase, and my car does not include luggage racks. I have looked online and have found really expensive luggage racks as well that are small.I have looked far and wide to find videos of luggage bags such as this being installed and I found one that showed my exact same model car and same-ish year. After reading through the comments of his video, looking for the exact bag, and reading through the reviews here I was convinced enough to buy this one. I got it within 2 days and it is big enough to fit multiple 32in suitcases no problem, looks to be about 3 but i only have 2. It is roomy and it is sturdy as all hell.I will update once I take the trip with information on how it held up. Overall I am liking this bag and couldn't be more excited to have space in the car for more than just suitcases and being cramped.Update:I uploaded a picture just to show how it was set up and what it looked like.So we took the trip and this bag held up better than expected. It withstood rain heavy rain and hail and it stayed latched on even when going over 90MPH for a good 13 hours or roughly 700 miles.I have a few gripes though. The bag says it's waterproof but idk what what happened when going down there, my bag ended up getting soaked. On the way back it was not so it may just be user error. And it's having to tighten it enough down but the more you tighten, the more it tugs and messes with the weather strip, that it causes all the noise from outside to come into your vehicle if you aren't using the luggage rack. Which I would assume would be most cases since that's why I bought it. Oh and a lot of wind drag which caused my car to want to push harder and use more gas but that may just be an issue for me and not more common.Other than that, it is a solid bag. It has lots of room and is able to withstand heavy rain and hail, 90+MPH speeds for a long period of time. Would definitely recommend to anyone. Especially at this price point.
