Meet the HeartIn shirt: a smart t-shirt that makes it easier to keep an eye on your heart as you exercise. It comes with a Clip that measures ECG signals from your body. You can use the data to track aerobic load, recovery, and heart rate abnormalities.
The shirt has sweat wicking properties. It has snap-on data analysis electrodes, so you will just have to attach the heart tracking module to get started. The battery lasts up to 24 hours.
