Excellent bag, very large capacity and durability. It has many pockets, as well as the ability to expand (you close the zipper and reduce volume - number of compartments). One of the best for the spine (regarding "back" bags). Finally, it has a waterproof compartment at the bottom, integrated into the bag, for rainy situations. The colors are vibrant and beautiful, just like in the photo. Side pockets on both sides for water (mesh), as well as "pockets" with zippers. I washed it in the washing machine at 30 degrees and it didn't suffer any damage. I highly recommend it

Very nice and well-made bag. The only downside, and that's why I'm now in the process of getting a simpler one, is that it's quite heavy with the books inside.
