Your sense of style is uniquely you. Let the small/medium Garmin Vivo smart 3 in black complement that style without trying to overshadow it. Featuring a slim inconspicuous band Vivo smart 3 is as hip as anything in your closet. Even better it s a master of subtlety. The tracker s hidden display is only visible when you want it to be. When you re not using it it disappears into the device. It s the perfect companion for the office the gym the pool and everywhere in between. Before beginning any weight loss or exercise program you should consult with your physician.
