Review on 👜 Spacious and Convenient: CURT 18221 Extended Roof Rack Cargo Bag for All Your Travel Essentials by Chad Michels

As others have said this bag is not waterproof as the zipper is not waterproof. The bag is a clamshell, so the zip runs along three sides of its rectangle, with the only unzipped side (the "hinge") being on the long side. This makes it easier to get in and out of the bag and also means that one of the zipper sides (short) always faces forward when the bag is on the roof of the car (wind and rain). when your car drives down the street). Unfortunately, even if you leave both zippers at the back end of the bag (as one reviewer suggested as a solution), rain still seeps right through the zipper seam at the front of the bag. Adding a waterproof zipper to the bag would actually increase the cost (and retail price) of the bag and probably mean a lot of people wouldn't buy it, so I suspect the company dropped it. (The included zip isn't even the best non-waterproof zip - if you don't pull the bag along the zip to close it, it will crack, buckle, and miss teeth (corners are the worst). To compensate for the zip, the company has one Added flap that hangs over the zipper along which Velcro squares are attached at regular intervals to hold it in place.The wind simultaneously blows into the top flap, twisting it back and pressing on the bottom half of the zipper bag, eliminating the gap between the bag and valve is further enlarged.As a result, when the rainwater flies right under the valve, everything flows, and it is a zipper.Once the water is in the bag, there is no air or ventilation in it, the water just collects inside and seeps in your stuff in. If you don't pull it out and dry it as soon as possible, it will hatch the mold faster than you can believe. In short: either hope it doesn't rain while driving, or tape it off the valve and hope it stays on.
