Hi!
i want to get a backpack that is ard the 70L range and am considering between deuter air contact, aircontact lite and deuter quantum. for back system wise, may i know which one is supposed to be the most comfortable?
i understand that trying out is the best way to know which is one the most comfortable, but i am afraid that the difference in comfort will only be shown after prolong carrying.
how about lafuma landcrusier's back system? i looked through the website but the info was very limited.
thank you so much!
