The bag is excellent with a very good price!

Starting from the front, a small pocket about 1/3 of the bag with a hidden zipper from one side to the other.
On top, another compartment again with a zipper edge.
Now let's go to the 1st large compartment, where inside there is a divider, and 2 pockets with zippers.
Finally, the largest compartment.

All the zippers are of high quality!

2 pockets for a water bottle, one on each side, with elastic, a bit tight for a large bottle, but deep enough, so very convenient!
