we are humans, we made errors.
I start a topic about what was your biggest mistake when choosing your backpack.
I beggin : i live in a town where there is only decathlon for backpack choice.
My biggest error : don't understand that a backpack is like shoes : you have to try and test a lot before finding the one you are the more confortable with, whatever the weight of your gears.
And you? your biggest mistake?
I've definitely jumped onto a multi-day nature trip with a pack that was way too big (80L is tooooo much for me), and that I hadn't broken in. My back was rubbed raw and my knees were shot from the weight :(
