I'm buying too.
I'd like a backpack where I could fit also stuff for 2-3 day hikes, though maybe only 1 or 2 such per year.
And I don't plan to change 6x in between, so not overdo clothing quantity...
Don't know what minimal volume I should look at?
Like for ex Berghaus 35+8 - 79.99€
click And Deuter 59.55€
click Similar to this but 30+5. Probably too small, right?
