The KLICK FAST Button Dock is designed for use on button-down shirts and is particularly useful for carrying devices that need to be located right in the centre of the chest, e.g. body-worn video cameras. The "S"-shaped design attaches to a shirt placket by means of two shirt buttons. The slim profile ensures the attached device is carried as close as possible to the body. 

A version is available for both male shirts that have buttons on the right and female shirts that have buttons on the left
