The transverse shoulder and equip a plastic clip in the middle makes it easy to remove and remove the bag more easily than a backpack.
My fear was that this kind of bag is less convenient than a bag worn on the side, due to less access to the camera for input / output common. But finally, with the cross strap, you can easily rotate the bag (without lifting) to take the unit to 1 or 2 photos, then put it away. The closures were positioned on the right side to enable this type of use.
In addition to the main compartment, there is a small compartment on the top of the bag for storing some accessories (eg charger), a flat compartment on the entire rear surface (good for storing a tablet but can also be used for a portfolio some documents, etc.), and a small compartment under the bag, containing a canvas type raincoat designed to cover the bag. This allows more small compartment to store a raincoat for yourself (tested, it fits).
Finally, on the side an attachment for hanging a foot.
In conclusion, this is a bag for SLR camera very well thought out, with a good finish, which looks pretty robust, sober and efficient design, which allows you to store everything you need for your photo output.
