SLEEP TRACKING

How did you sleep? The Index Sleep Monitor gives you insight with sleep score, sleep stages, HRV status and more, so you can better understand how well you recovered.

COMFORTABLE DESIGN

Worn on the upper arm, this lightweight and breathable smart sleep band comes in two sizes, allowing you to get the data you need without compromising comfort.

SEAMLESS DATA SYNCING

The Index Sleep Monitor seamlessly syncs your data with the Garmin Connect™ smartphone app. If you wear a compatible Garmin smartwatch during the day or a heart rate monitor during workouts, your data will seamlessly sync via Garmin Connect for more insight into your health and fitness.

BREATHING VARIATIONS

For a closer glimpse of your health, the breathing variations feature uses Pulse Ox to help you better understand shifts in your breathing patterns as you sleep.
