That's what I call a master purchase. This product is cheap, practical and discreet. While it is not perfect, but it perfectly meets the purpose for which I intended. I have also bought a second one for my wife. This bag is enough to slide a box-type SLR (not seized) mounted a zoom transtandart in the "silos". There is still plenty of room (and unzipping, more) to put lots of personal effects. They reproach him his outside pockets that are missing at least one Velcro (it can nevertheless add), and the fact that it is not waterproof (it can also be corrected with a waterproofing spray).
