Designed to fit, built to perform. The HRM-Fit™ heart rate monitor is purpose-built for women — no matter how you move. It easily clips onto your medium- and high-support sports bras and provides accurate heart rate data to your compatible Garmin smartwatches and Edge® cycling computers, fitness equipment and smartphone apps. It also captures running dynamics — including vertical oscillation, ground contact time, stride length and more — to help you improve your form. Plus, for indoor runs, HRM-Fit sends pace and distance to your compatible watch. Keep going strong with up to 1 year of battery life.
