>>2402215What is the pro over an internal frame?
>>2402578Over the weekend is two nights/three days? I would maybe go for two backpacks then, one for commuting (something more robust, canvas, milsup) and one for weekends (like the one you picked, but larger).
I have a Fjällraven Bergen 30 and feel it's barely enough for an overnighter. There was a 40l version, whish i had it.
