I’ve got a large black Timbuk 2 courier bag, it’s ok.
Good points
It’s a courier bag so it’s cool
It’s got lots of pockets
It’s tough
It’s nicer to carry than the previous backpack thing I had
Bad points
All of the 11! pockets are layered on top of each other, so if you put anything in them it gradually becomes a bulging mass.
There are too many pockets, because it’s a bulging mass you can’t feel where the things are and have to go through all of the bloody things.
You can’t keep the main compartment tidy, stuff is just piled in on top of its self and it’s suprising difficult to dig into the bottom if you’ve got much in there
The laptop pocket is only padded on the inside, wtf is that all about?
I would not buy another for carrying books, laptop and files about, not really fit for this purpose imo.
