Pile the right size, and it is space above to bend the strap / strap the camera. In this way, once a closed, there are only the strap of the bag, and we will not tangle with 2 different straps.
I researched a bag with a closure "clips" instead of a front zip / zipper. Indeed, as I often go to the beach (waterproof camera), I do not want a zipper. The grains of sand are blocked inside.
The zipper is often not sustainable, and to react quickly, it is easier to open with this Tamrac system. It does not risk scratching the lens when the device enters or exits.
It is the ideal system that is most rare. I have found that the mark, and that's why I chose it.
The rest is also very well thought out, with front pocket, which takes up little space but can store memory cards, battery, or in my case, the small brush supplied with the unit to clean the gasket before immersion in water.
A sober look with a sturdy material and water resistant (I washed thoroughly before first use).
In short, the bag I've always dreamed of. I'll order another one for my companion.
