Nice finish bag, well designed with the number of pockets it takes to extra battery, memory cards, pen, notebook, and rain cover included. it contains easily, once the base extended by the clever zipper system (which gives it an old gas mask appearance). I put two photos online to confirm this handy countenance. A removable cushion with Velcro allows much the same stall with a 5D 70-200 F4. In addition to a backpack when the rest of the material is stored, it will allow the amateur motor sports or hiking to have before him, handy, well protected material. Well as convenient for photography in ULM. It remains to be tested in the length zippers, often loose first on high-end kind Lowepro bags (this happened to me, as to other colleagues). Price may be reluctant but value for money, value for money is very positive in my opinion.
