Very nice bag-to-back with a beautiful design. Possibility to store your pens, medicines, business cards and other small vessels of the genre in the second bag, when you consider that the third is necessarily the main one. Let's talk a little just the main compartment. Only downside in my opinion: no separation in the bag and that's a shame! Because of this manufacturing error (again in my opinion) this is me difficult or impossible to insert my paper documents without these wrinkle inevitably a bit because of this lack of separation. This is unfortunate because it has everything well, such as the possible location on the sides, cigarettes, cereal bars, bottled water, etc. Discreet, lightweight and rigid, however, he holds, and it is perfect summer during walks in the woods or countryside. Contains more than it seems!
