Sintesi SK, thanks to its small size, allows the execution of the electrostimulation programs even while moving. The base model is provided with a removable hook; for more comfort, the Sport Bag can be used. Its adjustable shoulder-belt permits you to wear it on the shoulder, or as a pouch, depending on the chosen program and on the activity in course. In case the training activity involves abrupt movements, both the shoulder-belt straps can be tightened, obtaining a perfect blocking of the device.
