Peak Design everyday 20L V2. 
I've used this bag for a couple photography outings and a few months of commuting. Has been well taken care of and never let me down. 
Absolutely no signs of wear or use apart from a coffee drop stain on the interior (see picture 3). Comes with all three dividers, exterior straps, and side straps (hidden in the magnetic front pocket and dual water bottle pockets).
This backpack is excellent for commuters or photographers. Only selling because I've recently changed cameras and need a slightly bigger bag for my new lenses.

Happy bidding!
