Waterproof 25 Cubic Feet Roof Top Cargo Carrier Bag with 6 Door Hooks - Universal Fit for All Vehicles (With/Without Roof Rack) - Perfect for Road Trips, Camping & Outdoor Adventures

My partner and I had a 4 day long camping trip we went on in another state. Both states are notorious for crazy canyon winds that you can feel your car being pushed around in. This thing held fast with no sliding or shifting, even when we were going 70mph and dealing with those winds.Secondly, there is SO much space in this carrier. We were able to fit 2 full size suit cases, 2 camping chairs, as well as 2 golf club bags full of supplies with wiggle room to spare.3rd and most importantly of all, the weather proofing. The last day of our camp it started to pour on is. Thunder, lightening, moderate winds, the works! This kept everything we had still inside bone dry, even with the car parked. On the drive back home we also dealt with more rain and even snow into the mountains. When we got home, everything still completely dry!The zippers are incredibly durable and easy to use. I could see that if you over stuffed the bag then you would run into issues of the zipper splitting or refusing to close up, but... Don't overfill it?Overall this was a phenomenal purchase and I would certainly buy another one for my second vehicle.
