Mainly I needed a protective pocket for my 5 inch mobile phone for work where it would otherwise be exposed to dirt and moisture. The additional bags I use for money and cards. all I wear then in my work pants in the side pockets, where it just fits in. The bag is well made and sturdy. Whether it is really waterproof, I doubt it. Think it still holds a couple of minutes longer through when the trousers from the rain is soaked ind right with me thus from. Refer to cell phone I'm only the Reissverschlußm without taking dieTasche to out of his pants. Strong buy recommendation. Was washed 2 times and looks like new !! Have now already the second in black for private. Was on US travel best services rendered. Although as I said great, but also on the belt to tragen.Und also fits in my Smarthie. :-))
