Has pros: I take this bag for the second time. Initially I knew that it suits me perfectly based on my needs, look at YouTube for a review of it, awesome backpack. Especially buzz that he is not afraid of water, that is, nothing gets wet in the rain. Got cons: I take off the star only because the pressure adjustment is made with some kind of fasteners, because of them it is inconvenient to let go of the backpack and tighten it, as I did with the old one.
