Percko is an invisible undershirt lined with tensors in the shape of your back with the idea of good posture in mind. It teaches and helps you how to develop a good posture. Without energy, Percko has a system that when you hunch, slouch or move in a position that is not good for your back, sensors are activated making you feel a slight stimulation in the right direction so you can re-adjust to a good posture. Percko is available in 7 different sizes (PK1, PK2, PK3, PK4, PK5, PK6, PK7) and in 2 colours: black and nude color. Click here to choose your size!
