It fits very much in, so I can also store the notebook, laptop and 2 smaller bags in the middle compartment.
Inside there is another pocket for looser list. In the middle compartment lid I stowed 3 pencils.
There are mutually hinged in which I have stored a lot of measuring tool and screwdriver and Bitkästen.
In a side pocket of a side cables are not stowed for quick use.
On the other hand is still a "mini" bag for further adapters etc.
Laterally are 2 pockets for mobile phone etc.
The processing of the bag is very good.
Even my side cutter and "drill" the needle-nose pliers not purely in the inside of the bag.
The soil is well padded, that the devices at a harder setting up, nothing happens (the middle compartment is still extra reinforced).
Even the rain makes the bag out of nothing, so this is perfect for the sales force.
This I would buy another time - but I think this is not too easy to get broken;)
