NEXPOW Car Rooftop Cargo Carrier Bag, 21 Cubic Feet Waterproof Heavy Duty 840D Car Roof Bag for All Vehicle with/Without Racks

I love this cargo bag ! I drive a Ford escape and have no cross bars so I had to use the door frame under the weather seal method and it worked just fine. It was so affordable and it worked so good! We made a 20 hour trip from MN to TX then back to MN 5 days later. we unstrapped it to get our stuff out 4 times total and each time it re-strapped onto the car just fine. The trick to get it to fit proper without the straps getting ripped or unravelling is you have to snug it flat against your roof and weigh the bag down front to back. It doesn't have to be the same weight all the way thru but it needs to be heavy stuff in the front because that's where the air pushes against constantly so if the front is weighted the air glides over the top of the carrier instead of under it. so we put our big suit cases up front towards the front part of the car and our lighter stuff towards the back also when you tie the straps make sure to knot the flappy excess piece's to the already tightened strap. Because if you don't they A. flap noisily the entire ride making you think your stuff is unstrapped and B. will wiggle themselves loose and your bag will flop around in the wind then the constant tension from your heavy cargo bag flopping about will cause the straps to snap. Make sure to point the unzippered part towards the front of your car it keeps everything water proof. we drove thru rain,snow and 5 hours worth of heavy zero visibility fog and our stuff was crisp and dry when we got to our destination. I 10/10, 100% recommend this cargo bag it is amazing for the price. and worth every penny.

We were stranded with our RV and needed to take more, than our cars boot would allow. We could stuff this bag and were able to take everything we needed. The quality is outstanding. We were driving through a long stretch of hard rain and everything inside stayed dry. Highly recommend.
