Garmin HRM 600 Heart Rate Monitor - XS-S

What Makes the Garmin HRM 600 Worth the Upgrade?

The Garmin HRM 600 is Garmin's premium chest-based heart rate monitor, built for athletes who want more than just heart rate data from a strap. It transmits accurate heart rate and HRV status to compatible Garmin watches and cycling computers, and adds Running Dynamics including step speed loss, a metric that quantifies how much you decelerate at ground contact during each stride. For cyclists, it delivers clean, stable heart rate data that doesn't dropout under hard efforts the way optical wrist sensors can. The XS-S size fits smaller frames with a secure, comfortable fit that stays in place across long rides, interval sessions, and race days. The strap module detaches for easy machine washing between sessions.

Battery life reaches up to two months on a single rechargeable charge, and the HRM 600 can record activity data independently when you are not wearing a paired watch, syncing heart rate, calories, speed, distance, and more directly to the Garmin Connect app after the fact. That standalone recording capability makes it useful during pool swims, gym sessions, and any workout where wearing a watch is impractical. It pairs via ANT+ and Bluetooth Smart to the full range of Garmin Edge computers, fenix and Forerunner watches, and third-party training platforms. For athletes who want the most complete cardio data Garmin's ecosystem can produce from a chest strap, the HRM 600 is the right tool.
