I use my S19 as my workday EDC, with a MacBook Air cache attached to the rear side. I'd like to be able to tether items to the opposite side of the interior, e.g. I have several of these cute recycled shopping bags that scrunch up into a tiny pouch with a carabiner.
However there are no o-rings in this part of the S19, so I was wondering if I could thread a 1" triangular metal hook (from the parts list) through the unused cache loops and use that instead. Anyone tried this, or something similar?
