Everything about this bags construction/material/functionality is fantastic. I have two observations for ALPAKA.
1 - This is a flight bag, there is a passport pouch with mag connection on the side, it doesn't quite fully fit a passport, the passport is still visible and doesn't feel totally secure from falling out or being picked, I would like to see a slight increase in the pouch depth just to fully remove the passport from sight.
2 - The bag slides all over the body when you move, very frustrating, the only option, a mag strap (also available) but far too big and obtrusive, this bag needs something thin and unassuming to stop it moving, perhaps a clip strap to that bag that can also clip to a belt loop or a press stud type option to go around a belt, similar to a shoulder holster. This would really optimise the bag and others in the range i feel.
