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 product changed our lives on road trips – Toyota Yaris owners
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.

Spacious and Functional, but Better for Side Rails
This rooftop cargo carrier held up great during our trip. It’s very spacious and kept everything secure and dry even through a rainstorm. The straps are sturdy, and I like that it comes with everything needed: reinforced straps, door hooks, a luggage lock, and a black topper mat.That said, the mat came off mid-drive, which was a bit frustrating. Installation took some time and felt a little finicky. It definitely seems like it would perform better with side rails rather than just parallel bars. With a bit of adjusting, though, it still worked for us.

Great purchase
I don’t typically write reviews but this cargo bag literally saved my trip. I recently traveled from Virginia to Florida with my family and we needed more room in the car to ensure a more comfortable drive. This bag did exactly that. I have a SUV with a roof rack so it was super easy to install using the side rails. It held 5 small suit cases, a beach canopy, beach chairs and a few additional small bags. It rained while we were on the road and everything stayed dry. We got up to speeds of 90 mph and the bag did not move. It was very secure. It was also extremely affordable to purchase and was overall a very good product!

Not waterproof but sturdy and good amount fit inside
This held a lot of stuff! It secured really well to the top of my civic and didn’t budge my entire trip from Florida to Pennsylvania! I was nervous it was going to slide but it stayed in place even going 90 on the highway a few times. I filled it once it was on the top of the car, it was just easier for me. I gave it 3 stars because it wasn’t waterproof even though I installed it correctly. My trip took 2 days, I rained pretty good the first day and when I arrived a lot of my stuff was soaked, a few things were damaged. I would have returned it but I threw away the packaging.

Looks good, holds heaps of stuff. Survived an epic journey across Australia with no issues at all.

We used this Car Roof Bag Cargo Carrier (21 Cubic Feet) for a 5-night camping trip, and it was absolutely amazing! It was extremely spacious — we packed everything we needed and still had room to spare. It held our tents, sleeping bags, clothes, and even extra camp gear with no problem at all.The waterproof material kept everything dry through heavy rain, and the anti-slip mat made sure it stayed perfectly in place the whole drive. The 8 reinforced straps and 6 door hooks made setup fast and secure, even though our vehicle doesn’t have a roof rack. It worked flawlessly!Honestly, this cargo carrier exceeded our expectations in every way. It made our trip so much more organized and stress-free. Highly recommend it for anyone planning a camping trip or road trip — it’s a game-changer!

Works well and is a cheaper option for car roof bags.
