Our smart apparel is a comfortable, convenient and accurate alternative to traditional heart rate monitoring chest straps that often bind, chafe and slip during workouts.

Close contact is the only way the sensors can do their job. Here's the easiest way to choose your size. Measure the circumference of your torso just below your chest muscles. This can be done with a fabric tape measure or with a piece of string and metal tape measure. Small (35 - 37 inches), medium (38 - 40 inches), large (41-43 inches), x-large (44-46 inches).
