Hello everyone,
This is what you want for carrying around your 7" Tablet too. I'm using a Samsung Galaxy TAB with a silicone protection cover and it slides in and out with no trouble and is snug enough that it doesn't slip around inside. I don't know where the translation "Breast Bag" comes from but in English it's a Shoulder Holster. Since it's no where near the Breast or Chest, seems something got lost in the translation to German. It fits comfortably on your side between the ribs and your hip and hangs on the shoulder and uses a elastic strap that spans over your back and surrounds the shoulder on the opposite side, which keeps it from sliding off the primary shoulder. That's why it's called a shoulder holster because it uses the shoulders for an almost undetectable way of concealing whatever you maybe carrying with you. A sturdy well constructed product that is easy and comfortable to wear and an excellent method of avoiding bulging pants pockets without worry of what has fallen out or removed without you being aware of what has happened.
Try it, You'll like it,
