In case you are curious about the Veenanv backpack from Ali Express, it is called the Hynes Eagle 28L on Amazon here in the US, and there are reviews of it on the Amazon page. I actually bought this bag myself because it was so cheap, and it holds a surprising amount. I did a short video review of it. The main thing that makes it not perfect for me is the laptop compartment is not TSA scanner compliant. How hard does it have to be to find a sub 30 liter, clamshell opening, TSA laptop compliant bag??
