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.

Traveled just over 1700 miles, trip included heavy rain. Carrier stayed intact and everything inside remained dry.

We finally had a chance to use this bag on a recent road trip. Unfortunately we couldn't test how well it keeps water out since we didn't run into a single drop of rain but as far as usefulness, it will definitely come in handy for future trips as it holds A LOT of stuff and the zipper seems pretty heavy duty. We loaded 2 full sized luggages, a carryon and a ton of random things for my MIL to sell at her thrift store like kids clothes, toys, shoes, etc and still had a ridiculous amount of space for whatever. The straps held very well considering how tight I made them and I love that there's 10 of them as I like a lot of reinforcement on open loads. The zipper tends to snag at the corners which started to annoy me, that's my only reason for the 4 stars. Overall, I recommend it as the price is very reasonable for what you get.

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.

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.

Worked as described. At first, I was hesitant because I don't have the racks on the roof of my car, but we use the clips to the door and it worked perfectly.

Looking forward to using it for family vacation end of May
