The bag has a good shape, that's inner life also OK, but a major deficiency: the two side pockets are not closed, there is only one tiny inside pocket with zip, you can money, identity cards, .... other valuables NOT store, you can not insert the outside (memory cards, guides, keys, ....) falling sure with every move out. pity, even a bag specialist had to admit that you can retrofit anything (plastic ...). Therefore, unfortunately, back pocket is not recommended
