Garmin HRM-Fit Heart Rate Monitor for Women Purpose-built for women, HRM-Fit is the heart rate monitor you need to capture the important metrics -; all with a comfortable clip-on design. The clip-on design easily and comfortably attaches to medium- and high-support sports bras. So move freely and sweat it out -; HRM-Fit is with you all the way. Don’t worry about running out of juice. The HRM-Fit™ monitor gets up to 1 year of battery life. The HRM-Fit heart rate monitor transmits accurate real-time heart rate and performance data to your compatible Garmin smartwatches and Edge® bike computers, compatible fitness equipment, the Tacx Training™ app and other apps.
