Many pockets with or without zippers. Inside there is enough room for a laptop, 1 shelf 10 "1 7" tablet and supplies.
2 front pockets for your smartphone, pens and USB cables.
I think a 17 "laptop bag enters this despite the fact that it announced for a 15.6".
I thought to make a case for everyday but the impressive size dissuaded me, then it will transport my hardware gracefully.
In summary, a very nice bag, great practical and elegant HP and signed.
