Here's the most advanced Armband, or shall we say Case, well it’s both and it’s both designed to perfection, ultra shock proof case with ultra-strong detachable armband strap. The perfect and smart combination of a top quality case and an ultra-functional armband. You would only need to twist the armband in its place and there you go, you've got yourself an armband. 

It doesn't stop there, the case also features a magnetic plate installed at the back and therefore if you've got yourself a magnetic car holder, you won’t need to install a metal back plate between the case and your iPhone.
