Perfect, functional and safe!

Very happy with the smaller model, the flipside 200, I did not hesitate a second to buy the 400, before the expansion of my equipment park and especially since the purchase of a 200-400.
It contains easily my camera, a Sony A700, all his little connectivity, remote control, 2 sup batteries, memory cards and a second battery for the flash game, a type of flash cobra, a 18-250, a 100 macro, a 70-300 and a "big" 200-400. It remains a little place in case ......
My first selection criterion was the safety of the equipment.
No problem there.
This bag is sturdy, and protects very well reinforced materials properly.
In addition, the opening in the back also protects of possible hardware theft, in the crowd, when the bag is worn.
Very useful and safe in the walkabouts.
My second point was comfort. Both use, as back-delivery (logic for a backpack).
It's done well.
Comfortable to use, convenient access to the hardware, everything is stalled, it has an outside pocket integrating a protetion effective rainfall and a lil asticieux device and carry / hang a good sized tripod.
It is also very comfortable to wear back. Good straps, a lap belt good and wise and well padded reinforcements.
On top of all this, we must note the presence judicieusede large side pockets, can hold water bottle 1 liter eg, or anything else, and a large, wide compartment Advent, swallowing all the documents to carry.

Lil downer ....
I find it a shame before the whole place, the inexistence of a compartment isolated from the equipment, which could allow the transportation of a bottle of water or foods, safe for the material ... .. very useful for ptite hiking.
I do not take the risk of leaving a bottle and rub my equipment. The latter therefore finds place outside ....
This type of fund is reserved only classic opening models, not in the back ............. shame .....
I made the choice of personal safety equipment, the bag brought against the possible use of double-sided bag hiking gear .... Photo / groceries .....
To meditate as usual ;-)
