Worked great on 350 mile trip!

Great cargo bag! Was used on a 2020 Nissan Rogue Sport, included straps were great and added 2 ratchet straps cross wise over the top. Our drive was over 350 miles and it didn't budge and no rips or holes. Was loaded with 3 large duffle bags, 2 king size pillows, 2 body pillows, 2 back packs and still had room for more. There was no rain on the trip so I can not state if waterproof or not. Would purchase again and highly recommend for added storage on a vehicle. I do suggest to install on the roof prior to loading the cargo bag.

The Solution We Needed!

It's no fun moving from two different States and expecting it all to fit in a SUV; and this is where the cargo storage was the perfect solution. The 15cu was more than enough room and easy to secure on top. We went through rain and stayed dry too! Tough durable material with strong zippers!

This bag is well made and functional.

I actually needed another waterproof bag for the bed of my pickup truck. Am pleased with the quality of the bag and functionality of it also. Time will tell as to longevity but see nothing to think this will not serve me well for years. Would definitely buy again.
