Note however:
1- I have a ASUS 17.3 inches which just returned to the bag and the closure is tight and delicate so as not to scratch it with zip.
2- I would have liked a few "pockets" in the additional main compartment for easy storage of small parts (hard drives, cables, USB keys, etc.)
3- I am a bit skeptical when the life of the plastic end caps (blue) zippers. To see in time. It would have been better whether metal, including a power to padlock (this also applies to the semi-rigid compartment and front pocket).
4- A cover for the rain would have been welcome, especially for bikers!
Apart from these small imperfections, I am very happy with my purchase (although a bit "salty" price) and I recommend this bag.
