Unfortunately, it also has a catch: The iPhone is sitting pretty tight in the bag firmly. It is not so easy, herauszufummeln the phone out of his pocket when it rings. Especially when you're in a fast. It is virtually impossible to pull out the phone, without the bag to take only the belt and without to use the side buttons for volume and mute.
Another disadvantage that you can not operate the iPhone when it is in the pocket shows during operation as an MP3 player with an attached docking connector (eg to make it in the car being infected).
Conclusion: The case seems robust and the iPhone is the fact well protected - but unfortunately also before my visit ... I'm looking for I prefer a bag with hinged lid.
