This is a true messenger bag being wider than it is deep.
Big enough to fit a 14" laptop and A4 magazines, along with lots of accessible pockets and like the bigger bags the option of a suitcase pass-thru pocket.
Also a 2-in-1 so can e worn as both a shoulderbag and backpack.
Big enough to fit sunglasses, diary, wallet and keys.
Like it's larger siblings it has full width zipper pockets on the front and in the lining (for keeping passports etc safe) - plus a key loop for smaller items you need quick access too.
As standard it has a narrower 2.5cm strap, though this can be easily swapped for a wider (or different colour strap) if needed.
