My 70 liter bag showed up today. I am very pleased with the build quality. It actually appears to be airtight and all the connection points, handles, zipper, etc seem to be durable. The downsides are the the loading zipper is shorter than the bag and it closes kind of wonky. It will take some use to see how the flap with the backpack straps holds up. All-in-all a good deal for the price.
I couldn’t decide between this or this one for less. but I ended up going with the otter box 70. I like that it has the padding inside.
