The backpack has two pockets in total. One in the front with a zipper and another one in the back with reinforcement for the laptop. The inner pockets are very narrow and cannot fit many things. The backpack is ideal for clothes (bulky items but lightweight) and I would not recommend it to someone who has many small gadgets, as its organization is very minimal. The materials seem okay, but only time will tell how well the elastic side pockets for water bottles will hold up. The back takes shape depending on the things you load inside. This is not always a good thing.

As for the materials and quality, it's amazing!

It has a lot of storage space,
besides compartments for a laptop (16'') and tablet,
it also has a central space for everything else.
It also has spaces for water bottles on the left and right!

I am very satisfied so far.
I use it every day for a month.
