A laptop 15.6 "fits perfectly without forcing and is extremely well protected. The cupboards are multiple (pen, business card, passport, cd, telephone, MP3, ...) with a small outlet to run a cable for headphones so very convenient.
The shoulder strap was made to carry the cross in bag (that is to say, you wear the bag on one side and the strap rests on the opposite shoulder) which is more pleasant since the coup was not suffering more discomfort in the neck or other. However, it remains very well and very nice for a classic worn the same side.
Pleasantly surprised by the quality of this bag, I recommend it if you want to stay pro and modern at once.
