I'm considering buying a Cadet as I switch up my travelling style a bit.

I have a 15" 2015 Macbook Pro (retina) that I'd throw in the main compartment (no cache), and I wonder if someone could confirm if it'd depth-wise fit a Bose QC35 headphones case too (also in that main compartment)?

And, is there room for a Tri-star small or medium packing cube adjacent to the Bose headphones case?

Other than that my aim is to put the laptop charger and a Nalgene flask water bottle in the smaller front section.

Finally, anyone know if the very small front pocket holds a passport?
