I would like to add a bit more space (any way is acceptable) to my Deuter ACT Trail 32. http://www.deuter.com/US/us/hiking/act-trail-32-34432-119.html
I do understand it will not be a permament solution but for emergencies or for just walking from point A to B I would like to have this option.
An idea is put carabiners on the red circles below (there is another one on the other side).
