The AmpStrip™ is the first heart rate and activity monitor that is accurate, smart and comfortable enough to wear 24/7. Approximately the size of a Band-Aid, the AmpStrip is attached to the torso for the most accurate heart rate readings.
The open elliptical strip features a minimalistic, sporty design with a ridged texture that speaks to durability. It’s stylish enough to expose during a workout and thin enough to wear discreetly under clothes.
