XC SKI Dynamics

When paired with the HRM-Pro chest strap (sold separately), the ski power metric helps measure the actual exercise load of cross-country workouts.

Trail Run VO2 Max

Trail run VO2 max tracks your cardiovascular fitness level and adjusts based on trail conditions.

Wrist-Based Heart Rate

Optical heart rate technology gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart rate strap.

Pulse OX Sensor

For altitude acclimation or sleep monitoring, a Pulse Ox sensor uses light beams at your wrist to gauge how well your body is absorbing oxygen.

All Day Respiration

Track how you’re breathing throughout the day, during sleep, and during breathwork and activities such as yoga.

Advanced Sleep Monitoring

Get a full breakdown of your light, deep, and REM sleep stages as well as Pulse Ox and respiration data. View it all on a dedicated widget that includes your stress score and other insights.
