Garmin HRM 600 Heart Rate Monitor Chest Strap (M-XL) - Brand New

Elevate every session with the Garmin HRM 600 — a premium chest-strap heart rate monitor engineered for athletes who demand precise, real-time insight into their performance. From road runs and long rides to fast-paced team sports, the HRM 600 captures the data that matters most and syncs it effortlessly across your Garmin ecosystem. This listing is for the M–XL strap size, designed for a secure, comfortable fit across a wide range of body types.

Precision Heart Rate & HRV

At its core, the HRM 600 delivers accurate, real-time heart rate and heart rate variability (HRV) data, streaming directly to compatible Garmin smartwatches, cycling computers, fitness equipment, and training apps. Chest-strap monitoring remains the gold standard for accuracy, giving you confidence in every reading whether you're chasing a personal best or dialing in your training zones.

Stand-Alone Activity Recording

One of the HRM 600's standout features is its ability to record workouts entirely on its own. During activities where wearing a watch isn't practical — such as basketball, soccer, swimming drills, or contact sports — the HRM 600 captures your full session and syncs heart rate, calories, speed, distance, and more directly to the Garmin Connect smartphone app once you're back in range. No watch required, no data left behind.

Advanced Running Dynamics

Serious runners gain access to a deeper layer of form analysis. Pair the HRM 600 with a compatible Garmin smartwatch to unlock:

• Step Speed Loss — See exactly how much you slow down each time your foot strikes the ground.
• Stride Length — Track your stride to optimize efficiency and cadence.
• Vertical Oscillation — Measure the up-and-down motion of your torso to reduce wasted energy.
• Ground Contact Time Balance — Monitor left/right symmetry to help prevent imbalances and improve form.

All-Day Health Tracking

Beyond workouts, the HRM 600 keeps tabs on your daily wellness, logging estimated steps, heart rate, and calories burned, then syncing it all straight to Garmin Connect. It's a complete picture of your activity, from your morning warm-up to your evening cooldown.

Comfortable, Machine-Washable Design

The soft, adjustable M–XL strap is built for all-day comfort and stays put through the most intense efforts. When your session is done, the strap is fully machine-washable, keeping your gear fresh and ready for the next workout.
